Realm-cocoa: Realm.h not found via cocoapods

[lucasp90]

Goals

I've formatted my macbook and then I've made a fresh install of my development environment (latest XCode version, cocoapods 1.0.0). I've cloned an old Objective C project and downloaded all its dependencies using cocoapods. When i try to build it, it fails because of a missing Realm header. It's imported in my project as

#import "Realm.h"

Expected Results

The project builds as usual

Actual Results

Build failing: Realm.h not found

Steps to Reproduce

1. Include Realm 0.98.1
2. Import as #import "Realm.h"
3. Build the project

Realm version: 0.98.1

Xcode version: 7.3

iOS/OSX version: 8.4

Dependency manager + version: cocoapods 1.0.0,

Are you able to upgrade to Realm 1.0? If yes, then that may fix your issue.

[lucasp90]

I've made an upgrade to Realm 1.0.0 and now the not found file has changed:

/Users/me/ios-project/Pods/Realm/include/Realm.h:21:9: 'Realm/RLMArray.h' file not found

[stel]

Please try to clean the whole build folder path / DerivedData and build from scratch, see also https://github.com/realm/realm-cocoa/issues/3676 and https://github.com/realm/realm-cocoa/issues/3723

[lucasp90]

Hi! I have tried the first solution and the error persists: I'll list what I've done to make sure that I haven't missed anything:

First attempt

1. Download a clean version of the project
2. Go to the project's root
3. Execute the following commands

pod cache clean Realm
pod cache clean RealmSwift #Actually I dont need this since I'm using objective C, but I've added it just in case
pod install
pod deintegrate || rm -rf Pods
pod install --verbose

Result: I'm getting Realm.h not found

I'll try the second approach asap.

[stel]

Let us know if it helps. Also try to update CocoaPods and Realm to the latest versions.

[jpsim]

I'm closing this since we haven't heard back from @lucasp90 in a little while.

[lucasp90]

I'm sorry! I'm sure I'll be able to look at it next week.

[loveforgeter]

I also have the same issue, umbrella header not found. It seems like a bug of Cocoapods, public headers treat as private headers.

Update
Build success after setting User Header Search Paths to empty instead of ${PODS_ROOT}

[cbess]

@loveforgeter If you have cocoapods 1.0, make sure your build settings for "user paths" or something hasn't been overriden in your target

[lucasp90]

Well, I had to change my Macbook due to a hardware issue, so I ended up making a fresh install of cocoapods.

gem install cocoapods
pod setup --verbose
cd my/projects/folder
git clone <my repo>
cd path/to/my/repo
pod install

Without making any changes to the repo I'm getting "Realm.h not found"

After that, I've tried updating Realm to the latest version (1.0.1) I've finally made it pass the realm build (now I'm getting an error when I try to get the path of the default realm configuration, but I guess this is because of the library update and I'll read the docs to check it).

So, upgrading to the latest Realm version worked for me

[stel]

Thanks for letting us know, @lucasp90! Glad to hear that everything is fine now :)

[hcientist]

I seem to be having this issue. I have tried everything above (from #3676, #3723, and see below for my output from the verbose install mentioned at the end of https://github.com/realm/realm-cocoa/issues/3735#issuecomment-226522681 )

(please forgive my attempt at removing sensitive info from the message because i don't know what would be sensitive, and may have made the message useless?)

this is the error

@thegreatmichael what version of CocoaPods you use? Try to upgrade to the latest 1.0.1 version. Also check "Headers search paths" in your project's build settings, make sure that it doesn't override CocoaPods path.

[hcientist]

thanks for checking in @stel, i am on 1.0.1 /-: My User Header Search Paths is $(PODS_ROOT) recursive and $(PODS_ROOT)/ionicons recursive.

update:
so, i just started at the top of this thread again, I (have my project working fine on another machine, and so I) checked out my project again, did as in https://github.com/realm/realm-cocoa/issues/3735#issuecomment-226522681 and made sure my User Header Search Paths is empty, and doggonit, it works!!

[stel]

@thegreatmichael faced with this issue by myself today :) My solution was to remove all Xcode's Derived Data (or alt+shift+cmd+K in project). Glad to hear that you also resolved this issue :)
