Thanks for the submission @xunreal75

Is this causing the compilation to fail, or is it just a warning?

[xunreal75]

Hi, at the moment a warning on compilation with Apple Deploytarget 13. I had not tried to upload my App to Appstore

• perhaps you can replace

static UIViewController *RootViewController() { UIWindow *mainWindow = nil; if ( @available(iOS 13.0, *) ) { mainWindow = [UIApplication sharedApplication].windows.firstObject; [mainWindow makeKeyWindow]; } else { mainWindow = [UIApplication sharedApplication].keyWindow; } return mainWindow.rootViewController }

[xunreal75]

I ignore the warning. Upload and review to AppStore are successfully finished.

Hi, my app runs at emulator, but fails when building the IPA file. Output:

Created a PR (#1157) that will prevent the deprecation warning on iOS 13+
