I have the following code snippet with a simple map and map reader that shows a pin on the map when the user selects a location struct MapReaderTest: View { @State private var loc: CLLocationCoordinate2D? = nil var body: some View { MapReader { proxy in Map { UserAnnotation() if let loc { Marker(coordinate: loc, label: { Text("Marker") }) } } .onTapGesture { position in let position = proxy.convert(position, from: .local) loc = position } } } } This snippet compiles and works perfectly fine using Xcode version 16.4 building for iOS 18.0 and running on a device. This snippet also works for me when I build using Xcode 26 Beta and run in the canvas or simulator, however it does not work when I compile using Xcode 26 and run it on a physical device(I built and tested for both iOS 18.6 and iOS 26 Beta) Has anyone else had a similar issue / have any ideas for work arounds?
