UIView snapshot crashes in iOS app running natively on Apple Silicon

Question

I am using default snapshotView(afterScreenUpdates: false) in my app and it crashes on Mac Mini with M1 chip (Thread 1: EXC_BAD_ACCESS (code=1, address=0x20)

Also, I got the same crash with drawViewHierarchyInRect and all of this graphics/UI methods.

Any ideas what's wrong and how to fix it?

M1 is still a bit buggy but something like `drawViewHierarchyInRect` should work fine. It's probably something else that's causing the crash. — aheze, Jan 18 '21 at 22:34
@aheze you are right, it works in empty app in Swift, so the problem is more specific. Maybe some obj-c bridges thing, will check later. — Damik Minnegalimov, Jan 27 '21 at 14:18
I'll test it out. Which simulator and Xcode version are you using? — aheze, Jan 27 '21 at 16:40
@aheze I described, it's not in a simulator, its native iOS app on M1. Xcode 12.2 — Damik Minnegalimov, Jan 28 '21 at 14:33
Hi @DamikMinnegalimov , did you find the cause/workaround for this ? — hsafarya, May 12 '21 at 07:30

We also had this crash, suspected it had something to do with using a Metal layer in our app. Couldn't figure out the exact cause, but the issue seems to be resolved in macOS Monterey.
