Is anyone else seeing issues with ARkit Body Tracking and SwiftUI?
I am finding the the face tracking works fine if you have a view that appears with ARKit, does the tracking then goes away. This can consistently be done over and over by switching to the view and using it.
But I can't do the same with BodyTracking. If I have a view that is making use of BodyTracking then it only works if I show ONLY the view with the body tracking as the very first thing to appear when running the app. If I show any other views before switching to the one with the BodyTracking then it does not work. Also if I display that first view (which works fine) the switch to another view and back to the BodyTracking view then it no longer works.
This feels like a bug in ARKit, SwiftUI or iPadOS (don't have a phone to try it out).
Anyone else running into problems with SwiftUI and BodyTracking?
I get the following output when running my App (both when it works and when it doesn't). Feels to me like SwiftUI is causing issues with the tracking.
