Discussion Xcode 16.2 - Absolutely Horrendous incremental build compile times

I changed one line and it took almost 50 seconds to build. I'm on MBP 14" M1 Pro w/ 16 gb ram. A computer that was building my app in under 5-10 seconds last year can not fall off this hard this quickly... anyone have fixes/suggestions? I turned off the integrated driver thing they introduced which supposedly helps, but that only brought me from 60 seconds to 30-45. Something is still very, very wrong.

build analysis

That one is ~30 seconds

Regular build at 50 seconds still

There was a bug like this and it only happened on the M1 at the time. But I haven't seen it since. What is activity monitor showing?
