I can't edit my above comment - but DO NOT use the above method in a production app, this is just how I have been able to get it to work in testing. Don't hard code your .videoformat as it changes in different releases of iOS and for different devices.

Try using a New Private Window in Safari.

@Chengliang you get the gravity using import CoreMotion let motionManager = CMMotionManager() motionManager.deviceMotion?.gravity`

Any option when Objective C++ is present? That .dynamic fix didn't work in my case. - I guess make a new build target excluding all that code and use #if !TARGET conditionals? Gotta say it seems pretty silly that after all this switching to ARM from Intel that it's SwiftUI that's causing such a pain lol.
