Does `requestGeometryUpdate()` Override Orientation Lock by Design?
Hi everyone, I've been testing the requestGeometryUpdate() API in iOS, and I noticed something unexpected: it allows orientation changes even when the device’s orientation lock is enabled. Test Setup: Use requestGeometryUpdate() in a SwiftUI sample app to toggle between portrait and landscape (code below). Manually enable orientation lock in Control Center. Press a button to request an orientation change in sample app. Result: The orientation changes even when orientation lock is ON, which seems to override the expected system behavior. Questions: Is this intended behavior? Is there official documentation confirming whether this is expected? I haven’t found anything in Apple’s Human Interface Guidelines (HIG) or UIKit documentation that explicitly states this. Since this behavior affects a system-wide user setting, could using requestGeometryUpdate() in this way lead to App Store rejection? Since Apple has historically enforced respecting user settings, I want to clarify whether this approach is compliant. Would love any official guidance or insights from Apple engineers. Thanks! struct ContentView: View { @State private var isLandscape = false // Track current orientation state var body: some View { VStack { Text("Orientation Test") .font(.title) .padding() Button(action: toggleOrientation) { Text(isLandscape ? "Switch to Portrait" : "Switch to Landscape") .bold() .padding() .background(Color.blue) .foregroundColor(.white) .cornerRadius(10) } } } private func toggleOrientation() { guard let scene = UIApplication.shared.connectedScenes.first as? UIWindowScene else { print("No valid window scene found") return } // Toggle between portrait and landscape let newOrientation: UIInterfaceOrientationMask = isLandscape ? .portrait : .landscapeRight let geometryPreferences = UIWindowScene.GeometryPreferences.iOS(interfaceOrientations: newOrientation) scene.requestGeometryUpdate(geometryPreferences) { error in print("Failed to change orientation: \(error.localizedDescription)") } self.isLandscape.toggle() } }
