iOS App Store requires 64 bit. I changed from Mono2x to IL2CPP to solve this problem. My application launches the camera on startup. With IL2CPP it no longer launches the camera. Instead I get a black screen, or the app crashes. The log doesn’t say anything about it. What could cause this?
It could be a whole load of reasons. Take a look at the stack trace in XCode to see exactly where this is crashing (make sure you’re running in debug mode) and that’ll help you figure out where the problem lies.
