I hope Apple currently has a team focused on macOS perf.

I worked on the team in charge of improving iOS (13) perf at Apple and IIRC there was no dedicated macOS “task force” like the one on iOS.

Luckily some iOS changes permeated into macOS thanks to some shared codebases.

What changes permeated into macOS? What did your team do to improve iOS perf?

So many of the frameworks have shared code between macOS and iOS (e.g. MapKit, Foundation, Contacts etc..), so a perf fix in iOS pays dividends on macOS too.

Perf changes are too numerous to mention, I’d recommend watching last year’s WWDC keynote describing the iOS 12 v/s 13 perf advancements.
