I\'m sick to death of Xcode\'s prolific use of live \"unused variable\" warnings while I am typing. I keep thinking I have an error in my syntax, stop what I\'m doing, check
On my version (Xcode 10.2.1), it seems as if disabling live warnings only disables warnings, not all errors as others have said. So, I would think this exact answer addresses the original post quite well:
Xcode > Preferences > General > Issues: [x] Show live issues
Uncheck "Show live issues
". No more constant warnings as you type new code.
