Any tips on positioning a shutter button on camera screen (fullscreen preview) when device is in half-open state? As well as other centred controls (camera mode, etc)? How to handle hinge area updates? Thanks
This doesn't completely answer your question, but regarding hinge updates...
To ensure your interface correctly accounts for occlusions like the camera or Dynamic Island, or divisions like the hinge area or folding region, use ReservedRegion(SwiftUI) or UIView.ReservedRegion (UIKit) and query intersecting regions using reservedRegions(kind:options:layoutDirectionBehavior:) (SwiftUI) or reservedRegions(kind:options:) (UIKit).
In addition to reservedRegion you could also use ArrangementView
