Report

Crash at app startup after integrating an XCFramework through CocoaPods, which at the same time depends on other pods:

What did you do?

We have an SDK which depends on some pods. We currently bundle this SDK to a fat binary framework. We now want to bundle it using the new XCFramework format and distribute it through CocoaPods as a binary.
After including the binary to a project and run the app, we get this runtime crash on app startup.

We build the xcframework with the BUILD_LIBRARY_FOR_DISTRIBUTION flag set to YES.

This is our .podspec:

...
s.vendored_frameworks = '<MyFramework>.xcframework'
s.swift_version = '5.0'
...
s.dependency 'Kingfisher', '~>5.13.4'
...

What did you expect to happen?

App runs normally with the SDK installed via CocoaPods.

What happened instead?

Runtime crash on app startup

No.. I'm still having the same problem :/

[renescholze]

@nikitaame , @rserentill : I'm also struggling with this issue. Did you somehow solve this issue?

[dcortes22]

Any news on this issue?? @renescholze @nikitaame @rserentill I'm also facing this problem

Same here... any updates on this?

I have opened a new issue here incase if it helps anyone with sample repo code reference in it as well : https://github.com/CocoaPods/CocoaPods/issues/10185

[deepesh-vasthimal-cko]

@paulb777 can you please help me with this issue, I think last time you were looking for a sample repo you can find all this in my new issue raised here https://github.com/CocoaPods/CocoaPods/issues/10185

add below line in the pod file which sets the Build library for distribution to yes for all pods. Then update/install the pods. It solves the problem of crashing app at runtime
Add this to pod file of application where u had added xcframework

post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['BUILD_LIBRARY_FOR_DISTRIBUTION'] = 'YES'
end
end
end

@mayaTest you are top class , saviour, saved my day. Thank you so much, I added the script to client app and it worked, Adding it to the framework does not help but adding to the client app does the trick.

[sebastianludwig]

Since 1.10 the Build library for distribution setting of a target is inherited by its pods (see #9232 and 37cc010). So instead of the post_install hook activating that build setting for your app target also does the trick (+ running pod install again).

Maybe though this has some side effects I'm not aware of...

@mayaTest Thank you so much!

@mayaTest You saved my month 😭. Thank you very much.

@mayasomase It looks like you've done a great thing here. My question is do you know why this works?

post_install do |installer| installer.pods_project.targets.each do |target| target.build_configurations.each do |config| config.build_settings['BUILD_LIBRARY_FOR_DISTRIBUTION'] = 'YES' end end end

Can this be injected via the podspec so that the end-user is saved some agony?

Can this solution be implemented in podspec?

Not sure I didn't tried that....My requirement was to create xcframeworl so I tried that only
