I am fixing a project created before iOS 13 and my Build fails due to the below line because "KeyWindow" is depreciated. Login and Signup ViewController swift files. I've googled endlessly for a solution of which I find a billion methods but don't see how to specifically fix this.

Code Block guard let mainTabBarController = UIApplication.shared.keyWindow?.rootViewController as? MainTabBarController else { return }

Help!

You probably have to change as follows:

Code Block        UIApplication.shared.keyWindow

with

Code Block 	UIApplication.shared.windows[0]

@Claude31 That seems to have gotten rid of the errors. I cleaned the build folder and ran another build successfully.
