Im using Unity 5.52f1, when I try to submit my app to app store,
an error message say the app must be a 64bit one, I go back to Unity
Changed Scripting Backend from Mono2x to IL2CPP, no problem in unity
after build it with xcode and test it on any iOS devices, my app crash on start
Android experiences no problem
I think there might be something went wrong with the sql database
Your likely best to post this in the iOS section - but you’re also going to need to supply a lot more information than “app crash” - what’s the crash info (it’ll be in the console log, crash log, etc).
