I updated my MacOS and XCode this past week and now I have 15 errors that weren't there before and all dealing with the Podfiles. Most are can't build modules and not liking double quotes which the headers are supposed to be. How do I fix this as the XCode recommended fix makes it worse. Do I need to create new pods?

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. Help!
