This has been driving me nuts most of the day. Working on a header file in a framework, which means most of the app gets recompiled every build.

Xcode 16.2
M1 Ultra: builds in ~14s
M4 Max: builds in 14-220s+

So crazy, kept futzing around with spotlight, networking, devices, etc…

Nothing until I tried Xcode 16.3 beta 3
M1 Ultra: ~9s
M4 Max: ~6s

What the actual hell? I was probably a couple hours away from sending this thing back to Apple.
