Build for iOS results in a black screen before the splash screen and remains forever.

Unity Engine

I have a Unity application that works fine on android devices, but in iOS, it results in a black screen before the splash screen appears. There are no crashes, and the backtrace contains this. Can Anyone help me out to solve this? Thank you!

Looks like Firebase is angry.

To isolate, try rip out 100% of firebase stuff (I am assuming you are correctly using source control so all the damage can be instantly reverted with one click!) and build your app to prove it runs on iOS, then go back and troubleshoot the firebase installation, go through all the setup steps, etc.

Firebase is unfortunately one of the most challenging libraries to get right, mostly because they “try to be smart” and don’t quite make it in many cases.

Hi @Kurt-Dekker ,
Thank you very much. It was the Firebase SDK. Completely wiping the SDK up and re-adding a newer version did the work. Appreciate your help and am Sorry for the late reply!
