[REQUIRED] Please fill in the following fields:

• Unity editor version: 2020.3.31
• Xcode version: 14.0 (14A309)
• External Dependency Manager version: 1.2.171

• Features in External Dependency Manager in use: Android Resolver, iOS Resolver
• Plugins SDK in use: Firebase Core, Crashlytics, Cloud Messaging, Google Analytics, IronSource, Airship, AppsFlyer, WebView
• Platform you are using the Unity editor on: Mac

[REQUIRED] Please describe the issue here:

The Unity application crashes on launch only on iPhones with iOS version 12.1, with EDM4U version 1.2.171 or above. Don't throw any errors. When the app is launched we see only the "activity" screen for less than a second and then it crashes.
When we downgrade to EDM4U version 1.2.170 the application runs normally.

The issue repro rate is 100%.

You can reproduce this following this steps:

1. Create a new Unity project with the 2D template.
2. Add "com.google.external-dependency-manager-1.2.171.tgz" via Package Manager. Link to archive -https://developers.google.com/unity/archive#external_dependency_manager_for_unity
3. Add "com.google.firebase.app-9.5.0.tgz" via Package Manager. Link to archive - https://developers.google.com/unity/archive#firebase_app_core
4. From Build Settings switch to iOS.
5. Check Symilink Unity libraries and Development Build.
6. Build.
7. In Xcode set Enable Bitcode to NO for both Unity-iPhone and UnityFreamwork.
8. Run.

Thank you for your great work and "heads free" tool.

Hi @Antonio-Iliev,

Thanks for reporting this. It's possible that the issue may be due to newer SDKs deprecating support for lower iOS versions. Let me bring this up to the team so we can confirm this.

Also, I see that you're importing a Firebase dependency. Could you try importing a .tgz file corresponding to a Firebase product and see if the behavior persists? Additionally, does the issue occur in any iOS version higher than 12.1 but lower than 13?

Hi @paulinon,
Thanks for your quick response.
Could you try importing a .tgz file corresponding to a Firebase product and see if the behavior persists? - I used the Package Manager to import a .tgz file for Firebase to reproduce the problem. The problem occurs for both Firebase versions 9.1.0 and 9.5.0
does the issue occur in any iOS version higher than 12.1 but lower than 13? - No, the problem only occurs on iOS 12.1 version. I tried on 12.3, and there aren't any problems.

So EDM4U 1.2.71 changed the Enable Swift Framework Support Workaround setting to be on by default, which was done because of the increased need for Swift support. With 1.2.71, if you try changing that in the Unity Editor, Assets > External Dependency Manager > iOS Resolver > Settings, does that affect the problem you are seeing?

Also, I know things change a lot with Xcode versions, what Xcode version are you using?

Hi @a-maurice,
Thank you for the suggestion. Unfortunately, there is no difference with or without the Enable Swift Framework Support Workaround.

I'm using Xcode version 14.0.

@chkuang-g Thanks for fixing my title typo. :)
