After a day of attempts to fix a stuttering UI, I gave in and opened Instruments. results were, of course, amazing. When I understood the real source of the slowdown it was easy to fix.
I’d like to get in the habit of using Instruments first, before wasting a day… no, really, I would, honest… but Instruments isn’t easy to use. It looks pretty enough, but the UI is strange bordering on arcane. I’m pretty sure I’m not alone in feeling this way.
If Apple Instruments just a bit easier to use, a bit less unique, and a bit less clever, I’m almost certain most developers would use it all the time. Imagine how much better all our apps would be.
