ARFoundation integrated in ios native app as library crashes with EXC_BAD_ACCESS error #337

Closed pnok closed 4 years ago

pnok commented 4 years ago

I built an AR iOS project using ARFoundation 1.5.0, ARKit XR plugin 2.2.0, with Unity 2018.4.8f1 version and XCode 11.

As standalone iOS app it works.

Then I tried to integrate the Unity XCode project as library in an exisisting ios native project. The build process succeeded, but as soon as I ran the app on an iphone 7 plus device it crashed with EXC_BAD_ACCESS.

The error has been raised by the unity_init func in AppDelegate class. In details the crash happens at UnityInitRuntime inside the unity_init function.

Any suggestions?

Thanks

Since nobody else bothered to do it, I have reported this issue being caused by MultiThreaded Rendering at Unity Bug: IN-35599 - [AR Foundation] MultiThreaded Rendering crash AR Foundation when enable/disable AR Session on iOS+Android
