I didn’t try running on iOS Simulator, I don’t think it’s important.
I am testing on real iPhone 8, real iPad Pro 12.9 1st gen with latest iOS.
Doesn’t seem to crash on iPad 2 with iOS 9.3.5, that is 32 bit device.
On the video I am using QuickTime Player to show the screen of my real device for the recording and you can see ARM-64 in the crash report.
