Thanks for your service on Xcode.

In my experience, it’s quite “crashy.” It often locks up so bad, that I need to force-quit (or force-restart the Mac). I end up doing that once a day, or so. I suspect that many of the performance and stability issues, have to do with resource usage. It’s a damn big app.

It can also end up in strange states, where portions of the UI fall “out of sync,” and the app needs to be restarted. Some operations (like opening a storyboard, or stopping at a breakpoint) introduce massive delays.

It’s not a denigration, calling something a UI shell. I’m working on one, right now. The engine and backend were done in April (started in February), and all the work since, was on the UI shell. I probably could have shipped something that “ticked all the boxes,” in May. It’s almost done, but there’s still a couple of months of testing, ahead.
