Xcode Unity build: app freezes and has some errors

Question

The app successfully built to Google Play as well as WebGL. I've tried switching all kinds of build settings in Unity, which leads me to believe there's something wrong in Xcode.

I also get these: dyld`dyld_fatal_error: -> 0x1200ed088 <+0>: brk #0x3

dyld`_dyld_start:

Any ideas what is the problem? All tutorials and guides I look at just fill in code signing and all that, and launch the project like nothing is wrong.

Answer 1

This was fixed by changing scripting backend from Mono2x to IL2CPP in the Unity settings for iOS. Also set the architecture to universal. No idea why this works, but I won't complain.

Answer 2

Have you tried build with "Device SDK" instead of "Simulator SDK" in player setting? I found an answer here
