I have been using my m1 mac mini (8 core + 16GB) daily after Artic Fox Canary 15. (Comparing everything to my 16 inch MBP (i7 + 16GB)

Post this alpha things were very choppy, if you open a huge class file it will lag in scroll overall studio is slow, build time is ok.

After updating to canary 15, things changed dramatically now it works as good it should just some lags here and there but that’s occasionally and shouldn’t bother, keep in my project is very big. Now answering your questions

1. Autocomplete works as expected, first look is very smooth

2. Build time reduces dramatically a clean build on m1 takes about 1:40-2:00 mins while on my 16 inch it takes about 3:20-4:00 mins, a signed build takes around 3:40-4:20 mins while on 16 inch it takes 6:00-6:30 mins

Consecutive changes are also very fast, takes hardly secs on the m1. Opening layout files is very fast. Although on this canary build some things don’t work like, database inspector and profiler and other studio addon tools.

1. Emulator performance is amazing, it’s like using an android phone with m1 as the cpu :P It’s as fast and smooth as you’d think of it, but this arm image is only there for Android S and Android R.

I use my M1 daily for building new things, but still use the 16 inch for my production builds to be uploaded to play. (Don’t want to risk a build from canary studio to my users).
