Re: Xcode 11 unusable?


I assume this happens in any Xcode project and not just your own?

Open and check various logs to see if anything Xcode-related is being dumped.
Sample Xcode (using Activity Monitor or the 'sample' tool) and see if it's spending a ton of time in something suspicious-looking.
Definitely submit a bug report to Apple. The Feedback app will collect a profile.
