Flutter: "Flutter/Flutter.h not found." on iOS.
Steps to Reproduce
Preface:
I'm on the flutter master channel and have run upgrade half an hour ago.
I've reinstalled flutter and cocoapods completely before and tried the fixes provided in #15437, #15532 and all other issues on GitHub looking like the problem I have. _
flutter create --template=plugin -i swift health_stats

I did not have path_provider version 0.4.0 in my dart packages folder before running the app, so it's a fresh copy.

In the health_stats project, your example/ios/Podfile appears to be almost full day older than example/ios/Podfile.lock. Perhaps the former has been copied from somewhere? I believe the consequence of a Podfile older than Podfile.lock is that pod install isn't executed as part of flutter run. This is consistent with the log output at the start of your Logs section.
Can I ask you to remove example/ios/Podfile.lock and retry flutter run in health_stats?
(Meanwhile, I'll be trying to reproduce the error of the regular project.)

Thank you very much for your speedy reply.
I have made this project around an hour ago (IIRC), so everything is newly generated, so I don't know how the dates are that inconsistent.
I have deleted the example/ios/Podfile.lock in the health_stats project and ran flutter run, to no avail, unfortunately.

You did get a Running pod install... line in your output now. OK, ruled that one out then.
I could not reproduce the error you get in the regular project.
Just noticed that your Cocoapods installation is 1.5.0.beta.1. Flutter tooling has not been tested with that version as far as I know. The regular project works for me with the path_provider dependency using Flutter master and Cocoapods 1.4.0.
mravn-google
on 28 Mar 2018
Ok, thanks for checking.
I've uninstalled Cocoapods using gem and installed version 1.4.0 (using sudo gem install cocoapods -v 1.4.0) but sadly get the exact same output as before.
jeroen-meijer
on 28 Mar 2018
Did you redo pod installation after the downgrade of Cocoapods? The health_stats project also works for me after deleting example/ios/Podfile.lock and example/ios/Pods/.
And flutter clean.
mravn-google
on 28 Mar 2018
Well, after running pod install inside the example/ios folder, health_stats works!
Sadly, doing the same thing for regular and running it still gives me this:

I should mention that I got this error even before installing Cocoapods 1.5.0.beta.1.
So these are two separate problems apparently.

jeroen-meijer
on 28 Mar 2018
Your Podfile in regular does not seem to contain the fix of #15437.
mravn-google
on 28 Mar 2018
What fix are you referring to?
If you meant this workaround:
target.headers_build_phase.files.each do |file|
file.settings = { 'ATTRIBUTES' => ['Public'] }
end
I just added it, removed Podfile.lock, ran pod install in the ios folder and ran flutter run, but still get the same output.
jeroen-meijer
on 28 Mar 2018
Sorry, my bad. That fix is relevant for Swift projects only.
mravn-google
on 28 Mar 2018
No problem. Very useful to know, though.
Any other suggestions?
jeroen-meijer
on 28 Mar 2018
No currently, I'm afraid. I cannot reproduce the error you get.
mravn-google
on 28 Mar 2018
I understand.
I want to try to reinstall everything I can to see if that fixes anything.
Do you perhaps have a list of tools and programs that flutter uses so I can uninstall and reinstall it all, including dependencies that get installed on the side?
For example:
- flutter
- cocoapods
...
flutter doctor -v should give you some indication. For iOS, mine says
[✓] iOS toolchain - develop for iOS devices (Xcode 9.2)
• Xcode at /Applications/Xcode.app/Contents/Developer
• Xcode 9.2, Build version 9C40b
• ios-deploy 1.9.2
• CocoaPods version 1.4.0
One might hope that it is enough to recreate the regular project now that you've downgraded your Cocoapods.

@0916174
Both myself and another person on the flutter gitter chat app had the same issue where we were using the cocoapods beta version. We both downgraded to version 1.4 -> deleted the Podfile.lock file -> deleted the pods directory -> ran flutter clean -> ran pod install -> flutter run worked for both of us after performing these steps.

Thanks for the suggestion. I've tried that just now. That also didn't work for me. Looking into doing a complete Mac reinstall, but I'm really not looking forward to it and want to avoid it at all costs.

I changed channel to beta on flutter and it works fine.
magillus
on 5 Apr 2018
I am able to reproduce the error consistently using Cocoapods 1.5.0 (newly released) and freshly created Flutter projects (from Flutter master).
It appears Cocoapods 1.5.0 deals differently with symlinks than some earlier versions, leading to a situation where the Flutter pod is effectively empty inside the Xcode project.
The fix of #16273 appears to solve the problem. You can make this change manually to the ios/Podfile in your existing project, then delete ios/Podfile.lock and ios/Pods/.
I have tested that the changed Podfiles work with both Cocoapods 1.4.0 and Cocoapods 1.5.0. I have so far been unable to reproduce the issue with the former.
mravn-google
on 5 Apr 2018
Thanks for this suggestion.
Uninstalled cocoapods completely and ran brew install cocoapods. It installed 1.5.0 as expected. I ran pod setup, flutter channel master, flutter upgrade and made a new project, added the path_provider dependency like before and ran it. Still get the same result.
Edit
I noticed this in the output for running pod update in the ios folder:
...
Analyzing dependencies
Fetching podspec for `Flutter` from `Pods/.symlinks/flutter/ios`
Fetching podspec for `path_provider` from `Pods/.symlinks/plugins/path_provider/ios`
Downloading dependencies
Using Flutter (1.0.0)
Using path_provider (0.0.1)
...
Are these version numbers for Flutter and path_provider correct? Shouldn't path_provider's version be 0.4.0 like I defined in the pubspec.yaml file?
jeroen-meijer
on 6 Apr 2018
Flutter plugins don't really use Pod versions so they all stay at 0.0.1 or whatever.
Updating Flutter will not give you a new ios/Podfile, because Flutter tooling doesn't overwrite it, if it already exists. You need to manually edit it with the changes of #16273, or delete it, after which flutter run will recreate it. You might need to delete ios/Podfile.lock and ios/Pods too before executing flutter run.
Edit: sorry, I missed the place where you write "made a new project".
mravn-google
on 6 Apr 2018
@0916174 I cannot reproduce with a freshly updated Flutter master (including #16273).

It's the same error (just a different dependency).
So it's machine specific, or rather, something your new machine and mine have in common that creates this problem.

Looks like thats is issue with cocoapods https://github.com/CocoaPods/CocoaPods/issues/7594

Ok, looks like I solved this. As it problem with cocoapods itself i just removed cocoapods from my machine and install version 1.4 with gem
sudo gem install cocoapods -v 1.4
then update pods in ios/ folder
cd ios
pod update
after this my project get alive on simulator

@Zmeu213 Thanks a lot. Have you tried if Cocoapods 1.5.0 works for you with Flutter master, so after https://github.com/flutter/flutter/pull/16273 landed? (Might require creating a new Flutter project and adding a plugin dependency to that to verify)
mravn-google
on 6 Apr 2018
Not sure. I switched flutter to master and dev couple of times, reinstalled it and force updated pods. But I didnt create new project with cocoapods 1.5 instaled. I dont know what version of cocoapods was installed on previous machine, it could also be just problem with migrating from 1.4 to 1.5. I only launched firebase example project with zero changes.
Zmeu213

adamkona
on 8 Apr 2018
For those who have updated Cocoapods with Homebrew and still haven't cleaned its cache, revert to 1.4 with brew switch cocoapods 1.4.0, then cd ios && pod update
It should compile now.

Good fix. Thank you @Zmeu213
wongalan2002

I agree that the fix of #16273 appears to solve the problem.
In my case, my flutter git branch is beta. So the #16273 commit was not applied.
I change flutter git branch like below.
cd flutter
git checkout master
git pull
flutter doctor
And then, there is no build problem when I build template project.
Note that, already existed projects will not be resolved.
You need to regenerate the project or manually edit ios/Podfile (for swift or for Object-C) file and delete ios/Podfile.lock
I think flutter 'Get Started: Install on macOS' page cause this problem.
That's because there is an old version of the SDK download link.
It should be changed to clone the latest version like below.
git clone -b master https://github.com/flutter/flutter.git
./flutter/bin/flutter --version

I've removed cocoapods again using brew and installed 1.4.0 according to @Zmeu213's solution and updated flutter to the latest master version just like to @bbongcol's . For me, it still does not compile, and I get the same result like always.
jeroen-meijer

@0916174 Have you looked into whether your Xcode may be at fault---your Xcode build version appears to be different from the one you get with a fresh download as of three days ago.
mravn-google
on 9 Apr 2018
$ xcodebuild -version
Xcode 9.3
Build version 9E145
I'll try doing a fresh install from the App Store. I'm also copying some commands from @bbongcol's Podfile from the referenced commit to see if that helps.
jeroen-meijer
on 9 Apr 2018
The project works! When copying the following from @bbongcol's Podfile, my project now runs properly:
...
use_frameworks!
...
pre_install do |installer|
# workaround for https://github.com/CocoaPods/CocoaPods/issues/3289
Pod::Installer::Xcode::TargetValidator.send(:define_method, :verify_no_static_framework_transitive_dependencies) {}
end
...
target.headers_build_phase.files.each do |file|
file.settings = { 'ATTRIBUTES' => ['Public'] }
end
I'll still get a new Xcode version just in case.
It seems there are differences in the Podfile between me and @bbongcol that my flutter installation isn't including in my generated Podfiles, but are essential for it to work properly. Is there any way to include these lines somewhere so they're automatically included when generating a new project?
Edit
This is my Xcode output right now:
$ xcodebuild -version
Xcode 9.3
Build version 9E145
Seems it's the same.
jeroen-meijer
on 9 Apr 2018
Ah OK, your Xcode is already upgraded to 9.3 stable, no need to reinstall. (12 days ago you used build version 9Q127n, see top of post).
mravn-google
on 9 Apr 2018
I believe I reinstalled it when I tried reinstalling everything flutter related here.
jeroen-meijer
on 9 Apr 2018
The Podfile differences listed above are needed for Swift-based Flutter projects, created with -i swift.

Not sure what you mean by this? The flutter installation contains two Podfile templates, one for Objective-C projects, one for Swift projects. They are supposed to be copied to your project when you add a plugin dependency and rebuild---unless you already have a Podfile in your project, in which case Flutter tooling does not overwrite it.
mravn-google
on 9 Apr 2018
The Podfile differences listed above are needed for Swift-based Flutter projects, created with -i swift.
That's strange since my newregular project just built and ran fine. When running another project however (an example project on redux by Brian Egan) it gave me some Dart related errors.
Guess I shouldn't be using that Swift podfile? In that case, I need a different solution.
jeroen-meijer
on 9 Apr 2018
The Swift Podfile may well work for ObjC projects too, we just haven't tested that.
mravn-google
on 9 Apr 2018
Not sure what you mean by this?...
When trying to use the Podfile I copied from @bbongcol, my project (a normal flutter create ... project without -i swift) built and ran fine. However, with the Podfile provided by flutter (without modifications) makes it crash with the Flutter.h not found error.
What I was trying to say was that those lines that are in the Swift Podfile are essential for my project to build. That's all.
So we now have a solution that works (using the -i swift Podfile) but isn't really a good solution, correct? Since everybody else says they can build projects without problems. It does help narrow the problem down, though.
jeroen-meijer
on 9 Apr 2018
I haven't tried Brian's sample projects, but I suspect they have not yet been upgraded to cope with Dart 2 runtime type checks. If so, you should be able to run them with the --no-preview-dart-2 flag.
mravn-google
on 9 Apr 2018
Woah that works!
So I guess for the near future, I'll have to copy that Podfile to all my new projects. Not a permanent solution, but good enough to get working.
Thank you very much for all your help. I think this issue can be closed now, if you deem it solved as well.
For people in the future having this problem, try the solutions above or use this Podfile (and run old projects with flutter run --no-preview-dart-2).
jeroen-meijer
on 9 Apr 2018
Well, that was a shortlived victory.
Same problem, now with the map_view package.
pubspec.yaml:
...
map_view: "^0.0.10"
...
I also had short lived victory but beta2 released recently fixed the issue.
magillus

Beta 2 seems to work for me as well. Not calling my victory too early this time, though. Let me do some more testing.

I was facing a similar issue. I ended up creating a new flutter project with these settings (currently tracking the master channel):

I compared the Podfile from the new project and the old project, this was the diff:

Then I deleted the ios/Pods directory, the ios/Podfile.lock file, the entire ~/.pub_cache directory, ran flutter clean, and finally flutter run. It worked after that.

It seems this problem is fixed.
I'm having a different problem now, similar to issues #15152, #15168 and #15050. I'll open a new issue for this problem since as of yet it seems there are no clear-cut answers to fix this, just workarounds.

@0916174 Can I ask you to try the following:
- make sure you have Cocoapods 1.5.0 installed (
pod --versionshould say1.5.0) - change any dependencies you have on the
firebase_xxx,google_sign_in, orcloud_firestoreplugins to the newest versions (look for changelog entries referring to Cocoapods 1.5.0) - change your
ios/Podfileto the newest version on Flutter master branch (https://github.com/flutter/flutter/tree/master/packages/flutter_tools/templates/cocoapods) - delete
ios/Podfile.lockandios/Pods - switch to Flutter master branch
flutter clean ; flutter run
Cf. #16443, flutter/plugins#483
mravn-google
on 12 Apr 2018
I've done so, same error.
I just remembered something that may be of value. When I said 'It seems this problem is fixed.' I was having a different error. To fix that, I commented use_frameworks! in the Podfile. Then I got the Flutter.h not found-error. After that, I uncommented use_frameworks! again like before I got the error, but the error persists.
I'll give this up and do a Mac reinstall soon. I don't see anything that could fix this.
If you come up with any suggestions, go ahead. Thanks for your help.
jeroen-meijer
on 12 Apr 2018
You should have use_frameworks! in your Podfile only if your Flutter project uses Swift
mravn-google
on 12 Apr 2018
I don't understand why this was closed @0916174 ? I don't see how this issue is solved.
Downgrading to 1.4.0 worked, sure, but shouldn't flutter support 1.5.0? Or is it still beta? then why is brew installing a beta version of this by default?
acidjazz
on 13 Apr 2018
I closed this since it seems it's a problem with my local machine. Any possible solution didn't work or temporarily worked and then stopped working again. I'll reopen it since it's still an issue, yes, but I'll be reinstalling my Mac OS (or getting a new one while I'm at it).
Things about flutter and the beta are better answered by the devs.
jeroen-meijer

@0916174 No I think you also found a legit bug with 1.5.0

@makalu-niko Thank you very much! It appears you are on Flutter's beta channel, and therefore the Podfile that Flutter tooling generates for your sandbox project is not based on the newest template from Flutter master.
I can thus reproduce the error with your Podfile, but not with the tip-of-tree version.
If you replace sandbox/ios/Podfile with that one and delete sandbox/ios/Podfile.lock and sandbox/ios/Pods/, then flutter clean ; flutter run should work.

@enrichman Does this mean that flutter run fails for a newly created Flutter project without any plugin dependencies added? Otherwise, can I ask you to share your pubspec.yaml file ios/Podfile (if present)?
mravn-google
on 15 Apr 2018
Does this mean that flutter run fails for a newly created Flutter project without any plugin dependencies added?
@mravn-google that's true. As you can see no Podfile in the project.
The pubspec.yaml is the default one (I've removed the comments):
name: cocoatest
description: A new Flutter project.
dependencies:
flutter:
sdk: flutter
cupertino_icons: ^0.1.0
dev_dependencies:
flutter_test:
sdk: flutter
flutter:
uses-material-design: true
Thanks for your quick support on this one. I'm not a iOS dev so I'm pretty lost on the errors coming from it (I didn't even know what a pod is 😂).
enrichman

@enrichman Now that is puzzling... I seem to have the exact same configuration you do

yet I cannot reproduce the error. What is the contents of your ios/Flutter folder and the Generated.xcconfig file within it? Mine look as follows:

The Headers folder is empty though:
enrichman
on 15 Apr 2018
Bingo. The Headers folder is not supposed to be empty! Indeed, mine contains all the FlutterXxx.h header files. These are supposed to be copied from your Flutter installation. In your case, /Users/enrico/development/flutter/bin/cache/artifacts/engine/ios/Flutter.framework. Is that folder empty too? If so, your Flutter installation is incomplete. I suggest you delete the flutter/bin/cache/ directory and then execute flutter doctor. That should download the files needed and recreate the cache. We'd then need to find out what caused your Flutter installation to end up in that state.
mravn-google
on 15 Apr 2018
Thanks you @mravn-google !
The folder was not empty but it was messed up with strange symlinks:
As you said clearing the cache rm -rf ~/Development/flutter/bin/cache and running a flutter doctor worked.
The Headers files were there and everything seems to work now.
Just created a new project and did a run without any issues. 🎉
Now I have to see what is breaking my original project, or how to fix it:

@enrichman all i did was at first i removed the 1.5.0 brew rm cocoapods and then switched to 1.4.0
brew switch cocoapods 1.4.0 it just worked for me there's some problems with 1.5.0.
ashim888
on 15 Apr 2018
@ashim888 I had troubles installing the 1.4.0 actually. I haven't found a way with brew. Maybe you have installed it previously, that's why brew switch doesn't work for me (I don't have the version locally).
brew switch cocoapods 1.4.0
Error: cocoapods not found in the Cellar.
brew install [email protected]
Error: No available formula with the name "[email protected]"
brew search cocoapods

cocoapods
Maybe later I'll try to see if installing manually the 1.4.0 could fix the issue, but this seems just a workaround and I would like to see if there is a solution.
enrichman
on 15 Apr 2018
@enrichman yeah me too searching for a solution, but that worked for me for now.
ashim888
on 15 Apr 2018
@ashim888 @enrichman The workarounds we had in place to use Cocoapods 1.4.0 resulted in iOS archives with link failures (see #15031), so I would not go that way.
@enrichman For us to help out with your original project with firebase_analytics, please share your pubspec.yaml and ios/Podfile.

Most of the above is just warnings which I guess you'll see only on the first build, because after that, the code involved has already been built. It seems the error, reported at the end, is the same as before.

I'm trying to downgrade my Cocoapods to see if I can solve this by downgrading it to 1.4.0. I used the code from this SO thread to do so:
sudo gem uninstall cocoapods
sudo gem install cocoapods -v 1.4.0
This my gem list:
When I run flutter doctor, it asks me to install cocoapods through brew:
brew install cocoapods
pod setup
Why does flutter not recognise that I have a cocoapods 1.4.0 installed through gem?
Also, when I tried brew install [email protected], it fails as the downgrade cannot be found.
Winghin2517
on 18 Apr 2018
It asks you to install via brew because the actual cocoapods gem wasn’t in your gem list for some reason.
cocoapods (1.4.0) was missing. It should be there above cocoapods-core (1.4.0).
jeroen-meijer
on 18 Apr 2018
It should not matter to Flutter how you install Cocoapods as long as the pod executable is on your path.
@0916174 Downgrading Cocoapods to 1.4.0 is unlikely to solve your problems, and Flutter tooling will be tested with Cocoapods 1.5.0 going forward.
mravn-google
on 18 Apr 2018
@mravn-google the problem is that I already have the exactly same file.
I've tried to do the same on my other Mac and it works with no issues. It's probably something that I broke on my machine that causes the issue.
It seems that the flutter run links the files in the cache in a strange way (@see), and since they're referenced in the .symlinks dir under ios/Pods something weird happens.
On my second Mac, after the flutter run, they're ok.
I'll try to delete flutter and reinstall it.
enrichman
on 18 Apr 2018
@enrichman If the contents of <flutter_install_dir>/bin/cache is broken, just delete bin/cache, then run flutter doctor. I'd be very interested in learning steps to reproduce the self-symlinks you get.
mravn-google
on 18 Apr 2018
@mravn-google i'm try to delete bin/cache, then run flutter doctor, and then flutter run, but still have the errors.
arden
on 18 Apr 2018
@mravn-google already did that, also deleting the .pub-cache of the dependencies but still getting the same behaviour.
The strange things that I did before getting the error was mainly switching branches of Flutter and recompiling with flutter doctor. Not sure if there are other "hidden" folders that I could try to clear.
enrichman
on 18 Apr 2018
@arden @enrichman Exact steps to reproduce would be very welcome. E.g. which project, with which dependencies (pubspec.yaml) and ios/Podfile (if any), are you running? Which version of Flutter are you using? (flutter doctor -v). Do you have the project open in Xcode while you perform these steps? Do you specify any parameters to flutter run?
mravn-google

@mravn-google
I've pulled the master and it doesn't even start, so I've tried to checkout the v0.3.0.
The steps were basically clear the caches:

Checked the Headers and they're still good.

@mravn-google thanks for your support. I've tried to reinstall flutter and cocoapods removing everything with no success.
The problem is on the pod install. After it I found the symlinks messed up.. Not sure on what is wrong but is related to my environment.

@enrichman One experiment to make is to modify the Podfile to keep the .symlinks folder outside Pods/, as a sibling of it instead.
mravn-google
on 19 Apr 2018
Something like this (not tested). And then add .symlinks to the ios/.gitignore file.

# platform :ios, '9.0'

@mravn-google Could you summarize the final, suggested workaround? It's unclear which steps are necessary and which are not. e.g. Do i need to be flutter master channel?

I have same issue with Flutter/Flutter.h but with audioplayer plugin.

For those with this problem these steps seemed to work with me:
1. uninstall cocoapods
$sudo gem uninstall cocoapods
$sudo gem uninstall -n/usr/local/bin cocoapods
2. install cocoapods 1.4
$sudo gem install cocoapods -v 1.4
3. update pod
$cd ios
4. pod
$pod update

miguelpruivo
on 20 Apr 2018
@miguelpruivo Going back to Cocoapods 1.4.0 is a short-term solution, at best. Flutter tooling (on Flutter master) does not support it, because we have been unable to make it work with Swift projects. You are advised to update your ios/Podfile instead.
mravn-google
on 20 Apr 2018
@mravn-google what are the steps to do so?
miguelpruivo
on 20 Apr 2018
@miguelpruivo Copy the Podfile suitable to your project from Flutter master to your project's ios/Podfile and delete ios/Podfile.lock. Use the ObjC version, if your Flutter project wasn't created with -i swift.

@mravn-google Sorry for being absent for a while.
I'm currently installing all the software on my new Mac, but haven't tried flutter yet.
However, while browsing my user files (~/Users/jeroen), I found this:
It seems the flutter headers everyone is talking about are stored incorrectly. Instead of ~/Users/jeroen/flutter/bin..., it's in ~/Users/jeroen/jeroen/flutter/bin....
While moving the folder to the correct location, I accidentally deleted my original flutter folder, so I can't test it out myself, but maybe other people here could check if their headers are in the incorrect folder as well.

I also had this happen and looked into it a bit. For some reason it tends to appear when flutter decides to switch from the engine built at 'ios-release' vs. 'ios'.
If that helps.
I was able to get partially back in business by deleting most all pod artifacts and then building through VSCode which I believe is building a debug artifact instead of a release artifact.

@mravn-google copying the Podfile from Flutter's master as you suggested fixed the Flutter.h not found issue but did not fix the The “Swift Language Version” (SWIFT_VERSION) build setting must be set to a supported value for targets which use Swift problem.
Adding this line to the post_install loop on build_configurations as suggested here makes it work after running pod install:
config.build_settings['SWIFT_VERSION'] = '3.2'
Wouldn't it be better to add this line to the Flutter's Podfile?

Then with 'flutter run' everything worked well.

iltumio
on 31 May 2018
So I tried the suggestion by @mravn-google and got the missing Flutter.h error to go away, however it introduced another issue. All of the plugins were moved in ios/.symlinks/plugins and xcode can't find them.
Is there a way I can set the directory where the plugins should be looked for? The failing lines in xcode just look like this:
import
(along with other package imports).
Thanks!

on 3 Jun 2018
There should be no need for auxiliary configuration to use plugins, beyond the Podfile that is distributed with Flutter. If you are having problems based on the project templates of the Flutter beta or master branches, please help us resolve it by filing a new issue, including the output of flutter doctor -v.

I don't see why this has been closed when we still have to copy a Podfile from master, shouldn't this stay open until flutter upgrade fixes it?
acidjazz
on 13 Jun 2018
@acidjazz flutter upgrade does not change your Flutter projects, it only updates your Flutter installation.
Specifically, once a Podfile exists in your Flutter project, Flutter tooling does not attempt to overwrite it, as you may have custom settings in there. As you note, this is unfortunate, because the Podfile was likely written by an earlier version of Flutter tooling using a template that does not work with newer CocoaPods versions and/or with Swift projects.
We are working on a project template with a clearer separation of the files Flutter tooling create and depend on (specifically, for plugins) and those that the app author is supposed to own.

Hi, I am not sure, But I think that I've tried all solutions I can find on this issue. I am totally new to Flutter and just running the basic test projects. Everything worked as a charm until i tried to start the app on my iPhone and had to enter information in the "xcode Runner". Before that on an Android device and in the simulator it worked fine.
Now it produces different errors but mostly I end up with the "Flutter/flutter.h" not found problem. (Only thing that works now is to run on Android phone) Please help me with this error, I've put more than a day of work to sort this problem out. Deleted all projects, uninstalling cocoapods and reinstalling it, trying different versions and so on.. Nothing helps, And oh, Flutter doctor is happy as always.

Hi, @Pergius , the workaround that worked for me was also described at this link (https://github.com/flutter/flutter/issues/24428#issue-381497805).
When copying the files to the ios-release folder, flutter build ios worked.
However, I believe there is a bug that needs to be fixed.

on 8 May 2019
I'm experiencing this on one of our build machines. I've tried reinstalling Flutter, switching to the stable channel, making sure cocoapods is the same version as on the working machines and pretty much every other solution suggested. The only temporary success I've had is with yxfmlbb's fix in https://github.com/flutter/flutter/issues/24428. The Flutter.framework header files are replaced with aliases that lead nowhere when I run build --release, and after that the iOS build fails with Flutter.h file not found.
I can only assume I haven't reinstalled Flutter completely. What else should I be doing besides deleting the Flutter installation directory?
Edit: this appears to be some weird Jenkins issue as running the same commands from terminal does not overwrite the header files with shortcuts.

I fixed this by doing pod install in my iOS project.
It seemed it was caused by updating flutter and then the podspec for flutter being out of date.

uncheck these two checkboxes when you create a new flutter project, it works for me.

Just run into the same problem. I removed the current pod files and pod folder I had, re-installed cocoapods, re run the app, and the issue was solved

For me this was solved by editing podfile as mentioned by this https://github.com/flutter/flutter/issues/10654#issuecomment-389034245 and change the xcode's build system to legacy.

I created a new app with flutter create my_app, deleted everything from ios/Flutter in my own app and copied everything from my_app/ios/Flutter back again in my own app. It worked :/
