iOS crashes on launch in release builds only

[mtostenson]

Unity version: 2018.2.1f1 React native version: 0.57.8

When running straight out of XCode, it works fine. However, creating a release IPA file results in an immediate crash on launch. We use fastlane to generate an IPA for beta testing, so we don't usually see this problem until then. I tested this using a blank react native project, and a blank unity project, and the crash is there. There are no useful crash logs unfortunately. Has anyone been able to publish an iOS release using this library?

Thanks

UPDATE: Setting "Strip Linked Product" to NO prevents this crash. However, this means the debug symbols are not removed and causes the app size to increase by 30-50%

FURTHER UPDATE The "Strip Linked Product" workaround does not appear to work for iOS 12.1.

Here is an issue I created in the react native repo that describes a possible solution.

Here's the crash report:

@alisherakb I was only able to build after downgrading to an older version of Unity 2018.1f2.

However, my initial version of Unity was v2018.3.13 when I encountered the error. react-native-unity-view: v1.3.3

I also made changes to the library's xcconfig file

In my case downgrading react-native-unity-view to 1.2.1 solved the issue. The error was occurring because of the UnityNativeModule.h that appeared in newer versions.

[psyrenpark]

same isuue. I solved it in the following way.

We also have the same issue at iphone XS MAX in ios 12.1.4 also ,still crashed, any idea?

yes i have the same issue at xs max and ipad pro

[techistoner]

I had problems with iOS Ad-Hoc / App Store Builds too. The app crashed immediately without any useful logs. Setting some compiler flags in XCode worked for me. You could give it a try.

ios/rnunitydemo.xcodeproj/project.pbxproj

COPY_PHASE_STRIP = YES;
ENABLE_BITCODE = NO;
STRIP_INSTALLED_PRODUCT = NO;

i have try it ,but still crash in xs max & ipad pro ,but no crash in iphone x & iphone 8plus
