Cordova-plugin-firebasex: iOS build freeze

[peterpeterparker]

Describe the bug
Hi Dave,

I installed the plugin as described in your comment in (https://github.com/arnesson/cordova-plugin-firebase/issues/1081#issuecomment-503135862).

With Android, all good, it works like a charm.

With iOS, on the other side, I'm not able to compile/build the app with the command line once I had this plugin to my app.

I use Cordova v9 and NodeJS v12

I tried many times to remove and add platforms and plugins but I always land on the same problem, when I run ionic cordova build ios the build will always freeze respectively it will hang on the following:

ProcessPCH /Users/myProject/platforms/ios/build/sharedpch/SharedPrecompiledHeaders/10438514788408785055/MyApp-Prefix.pch.gch /Users/myProject/platforms/ios/MyApp/MyApp-Prefix.pch normal x86_64 objective-c com.apple.compilers.llvm.clang.1_0.compiler (in target: MyApp)
cd /Users/myProject/platforms/ios
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang -x .... (a lot of lines) ... 8408785055/MyApp-Prefix.pch.dia

Interesting, if I abort the build and open the project in Xcode v10.2.1 I'm able to build the project in Xcode without any problem.

I also tried many times to reboot my laptop (Mac) thinking that maybe a process would remains blocker but nothing helped.

I'm not sure it's directly related to the plugin, maybe it's related to Cordova v9(?), but I definitely don't face it when I remove the plugin.

I'm aware it isn't probably an issue and most probably more a support question so I hope you will accept my apologies for that. Of course if you don't face the problem and would close the issue without any comment, that would be absolutely no problem.

Thx for all your cool work and again for your about the other issue of today!

P.S.: A sample repo to reproduce the problem

https://github.com/peterpeterparker/ios-build-freeze

[peterpeterparker]

Note, don't know if this is related but I do see the following warning at the begin of the build:

Pod installation complete! There are 7 dependencies from the Podfile and 19 total pods installed.

[!] The MyApp [Debug] target overrides the LD_RUNPATH_SEARCH_PATHS build setting defined in `Pods/Target Support Files/Pods-MyApp/Pods-MyApp.debug.xcconfig'. This can lead to problems with the CocoaPods installation

[!] The MyApp [Release] target overrides the LD_RUNPATH_SEARCH_PATHS build setting defined in `Pods/Target Support Files/Pods-MyApp/Pods-MyApp.release.xcconfig'. This can lead to problems with the CocoaPods installation

- Use the `$(inherited)` flag, or
- Remove the build settings from the target.
- Use the `$(inherited)` flag, or
- Remove the build settings from the target.

[dann95]

can you post config.xml plugins and package.json ?

[peterpeterparker]

@dann95 sure. I was able to reproduce the problem in a sample minimal project, here's the repo:

[Hanzofm]

Same problem:
/platforms/ios/build/sharedpch/SharedPrecompiledHeaders/8559664710397625761/myproject-Prefix.pch.dia

If I cancel de build and then go to xCODE and deploy to device it works perfectly

[dpa99c]

Will look into this today

[dpa99c]

I've tried to reproduce this issue in an isolated test case using the following commands:

cordova create test io.cordova.firebase.test && cd test
curl https://raw.githubusercontent.com/dpa99c/cordova-plugin-firebase-test/master/www/GoogleService-Info.plist -o GoogleService-Info.plist
cordova platform add ios@latest
cordova plugin add cordova-plugin-firebasex
# open project in Xcode and set development team
cordova build ios --device

But the build succeeds: console log

Please try the above commands in your environment and report the result.

[peterpeterparker]

thx @dpa99c

I could confirm that using the exact same commands as you I don't face the problem neither

On the other side when I do try out again the sample repo I provided in a fresh install I still face the error

Incompatibility with another plugin maybe?

[Hanzofm]

What do this?

curl https://raw.githubusercontent.com/dpa99c/cordova-plugin-firebase-test/master/www/GoogleService-Info.plist -o GoogleService-Info.plist

[dpa99c]

@Hanzofm it downloads a dummy iOS configuration file for the Firebase plugin.
Not sure if iOS build fails without it, but Android certainly does.

[dpa99c]

@peterpeterparker I'll clone your sample repo and investigate

[peterpeterparker]

thx a lot Dave for all your effort!

[dpa99c]

Some interesting results when testing with your project.

So I did:

git clone https://github.com/peterpeterparker/ios-build-freeze && cd ios-build-freeze
npm install
ionic cordova platform add ios@latest
ionic cordova build ios

And in this case I can replicate your observed results: the build command hangs on the clang step.

But if I do the same and instead use the Cordova (instead of Ionic) CLI to build, it doesn't hang and builds OK:

git clone https://github.com/peterpeterparker/ios-build-freeze && cd ios-build-freeze
npm install
ionic cordova platform add ios@latest
ionic cordova prepare ios
cordova build ios

And if I remove cordova-plugin-firebasex it builds OK with the Ionic CLI:

git clone https://github.com/peterpeterparker/ios-build-freeze && cd ios-build-freeze
npm install
cordova plugin rm cordova-plugin-firebasex
ionic cordova platform add ios@latest
ionic cordova build ios

I've no idea why it hangs with Ionic CLI and not Cordova but my recommendation would to be repeat my tests above and if it works OK using ionic CLI to prepare the platform and cordova CLI to build it, then go with this as a workaround for now.

[peterpeterparker]

excellent @dpa99c I'm agree and could confirm with your finding. For now one the following target/workaround does the job:

"scripts": {
      "ios": "ionic cordova prepare ios --prod && cordova build ios"
}

Should we ping the Ionic-cli repo?

[dpa99c]

Should we ping the Ionic-cli repo?

it does seem related to Ionic so might be worth opening an issue there and linking to this one

[peterpeterparker]

Agree @dpa99c

I have opened and issue in the Ionic CLI repo (https://github.com/ionic-team/ionic-cli/issues/4042) and therefore I close this issue. If you would follow the issue I would honestly don't mind ;)

Thx again for your great plugins and support 👍

[dpa99c]

a quick update:
I just tried the experiment again but this time installing the plugin direct from the git repo which contains an update to use <pod> instead of <framework type="podspec"> and the build succeeded with Ionic. Please try the following to see if you can confirm. If so I will publish the repo as a new plugin version.

git clone https://github.com/peterpeterparker/ios-build-freeze && cd ios-build-freeze
npm install
cordova plugin rm cordova-plugin-firebasex
cordova plugin add https://github.com/dpa99c/cordova-plugin-firebase.git #this took a while to install
ionic cordova platform add ios@latest
ionic cordova build ios

[peterpeterparker]

Awesome @dpa99c ! I confirm that it solves the issue, I was able to build my app (I skipped the sample repo and tried it directly in my app) using master branch of the plugin

Thx a lot!

[dpa99c]

I've published the current master branch of this plugin as [email protected]

[peterpeterparker]

It works like a charm, thx a lot @dpa99c !

[Hanzofm]

what is solved in 2.0.7?

[dann95]

what is solved in 2.0.7?

the generated Podfile.

[Hanzofm]

Then, now is possible to install normally?

[peterpeterparker]

Yes

[remifleurance]

Hello,
I have the exact same issue using the latest 2.1.2 version.

From the command line it hangs on :

[..] MyApp-Prefix.pch.dia

Opening and building on Xcode gives me the follow error :

So it seems to be still related to CocoaPods

[peterpeterparker]

@remifleurance maybe open a new issue?

I'm (still) good and mine was solved with v2.0.7 of the plugin, so maybe something changed since then

[dpa99c]

@remifleurance I just tried the following test with v2.1.2 and the iOS build succeeded:

ionic start test blank --cordova --package-id=cordova.plugins.diagnostic.example && cd test
ionic cordova plugin add cordova-plugin-firebasex
ionic cordova platform add ios@latest
ionic cordova build ios

Please try the same in your environment.

Note: I used package ID cordova.plugins.diagnostic.example because it's one for which I have a provisioning profile installed which supports push notifications, so you may need to use a different package name.

[remifleurance]

Thanks for you answers

@peterpeterparker I tried with 2.0.7 too, but the issue is still here

@dpa99c I gave it a try using my own package ID

ionic cordova build ios

is not freezing anymore. But I still have the same error on Xcode.

I'm using Xcode 10.1, Node 10.15.3 and Cordova 9.0.0

[remifleurance]

Ok, after trying different things I was able to solve this issue.
FirebaseCore/FirebaseCore.h was located in Pods folder.

So in Xcode I went to :

General tab > Linked Frameworks and Libraries

and opened Pods/Pods.xcodeproj
Doing so allowed Xcode to add all files prepared by Cocoapods.

Not sure if this is how Pods.xcodeproj is supposed to be included ?

[dpa99c]

If you open YourProject.xcworkspace (instead of YourProject.xcodeproj) in Xcode, both your Cordova app project and the Pods project will be loaded into Xcode.

[remifleurance]

Oh ok. I'm a beginner in Xcode, Cocoapods etc...
Thanks for this information

@JohnMokgokong I suggest the following:

• try building the example project using the Cordova CLI
• try creating a blank Ionic project, adding this plugin, then building with both Ionic and Cordova CLI

[elaval]

I am having a similar problem (freezing at Prefix.pch.dia) and noticed that it occurs if I do the build with an iPhone connected to the computer. If I disconnect it, and start the build from scratch, the it ends OK.

[alexdelgado]

I'm having the same issue using [email protected]

[rolinger]

I was running v6.0.7 but the ionic cordova build iOS simply, and cleanly, exited at Preparing Firebase on iOS - and no build files were actually created. So I downgraded to v6.0.6 and now I too am getting the freezing at myApp-Prefix.pch.dia point in the build. But this is only happening on iOS. I was successfully able to build and deploy my app on Android using v6.0.7.

update:
I just detached my test iPhone from my Mac, as @alexdelgado referenced above, and my app compiled cleanly with v6.0.6

I then reattached my test iPhone, did ionic cordova build iOS again, it hung again at the same spot. Very bizarre.

I then tried with `ionic cordova build ios --buildFlag='-UserModernBuildSystem=0', with phone attached to Mac, and it still hung.

[abomadi]

I have the same issue also without attaching an iphone

[afelipelli]

In case it helps someone: I restarted my mac and it was working fine until I had the same issue again. Then I restarted the shell (terminal) and it built fine. I can't really explain it but thought I'd give the tip.

[rolinger]

@afelipelli - I will try that out. How long did it work until it hung each time?

Obviously something is up with this build of firebasex...its annoying.

[theopavan]

@dpa99c It's a strange error ... it occurs when I use the command with '--device' and in a new project that I have never opened in Xcode. If I use Xcode (10.3) the project will work.

I try:

ionic start test blank --cordova --package-id=cordova.plugins.diagnostic.example && cd test
ionic cordova plugin add cordova-plugin-firebasex
ionic cordova platform add ios@latest
ionic cordova build ios --device

Obs.: I use build.json so I don't need to open Xcode for sign

for me, workarounds are:

• use 'ionic cordova prepare ios --prod && cordova build ios --device' or
• add to build.json --buildFlag='-UserModernBuildSystem=0' or
• open project with Xcode one time

For now in CI i use --buildFlag='-UserModernBuildSystem=0'

[dpa99c]

@theopavan yes, since ionic cordova prepare ios --prod && cordova build ios --device works but ionic cordova build ios --device does not, I can only conclude the cause of this issue is upstream in the way Ionic wraps the Cordova CLI so isn't something that can be resolved by this plugin in itself.

[dwieeb]

👋 For those using the Ionic CLI, I just released 5.3.0 with a fix for this. See CHANGELOG.md. Please feel free to let me know if there are other issues!

npm i -g ionic@latest

[brownoxford]

@dpa99c, @dwieeb With the latest 5.3.0 version of Ionic CLI I'm seeing success with ionic cordova build ios --debug --device, so there is some improvement, but I'm definitely still seeing some other issues when cordova-plugin-firebasex is installed - here is my test procedure:

This has been fixed in Ionic CLI 5.4.1 by https://github.com/ionic-team/ionic-cli/commit/44697cf4ebc77c656ac664c2ee08bcba052892af
