Two days into using Xcode 15 and I'm finding it quite unstable.
Firstly there are times where it just crashes. No idea why at the moment, it just goes.
Then there are the hangs. 100% CPU on one core and a completely unresponsive UI. Force Quit sees it as not responding and I have to kill it. Every time with this it's been a particular swift source code file that is causing the issue. Opening that file triggers something that hangs the UI, sometimes pretty quickly, sometimes after a few seconds.
It's always the same files too. Completely reproducible. Most sources are fine, it's just the odd one that locks up 15.
In all cases the sources compile fine. So it appears to be something in Xcode that's getting itself in knots.
