iOS 16 Scene orientation issue

Question

I always received this error when I tried to allowed only portrait orientation on my controller: Error Domain=UISceneErrorDomain Code=101 "None of the requested orientations are supported by the view controller. Requested: landscapeLeft; Supported: portrait" UserInfo={NSLocalizedDescription=None of the requested orientations are supported by the view controller. Requested: landscapeLeft; Supported: portrait}

I called this method:

func updateOrientation(orientation: UIInterfaceOrientationMask) {
        if #available(iOS 16, *) {
            DispatchQueue.main.async {
                let windowScene = UIApplication.shared.connectedScenes.first as? UIWindowScene
                self.setNeedsUpdateOfSupportedInterfaceOrientations()
                self.navigationController?.setNeedsUpdateOfSupportedInterfaceOrientations()
                windowScene?.requestGeometryUpdate(.iOS(interfaceOrientations: orientation)) { error in
                    print(error)
                    print(windowScene?.effectiveGeometry )
                }
            }
        }
    }

Did someone face the same issue ?

It looks like a workaround, but it's fixed the problem in my case.

the trick is to update the AppDelegate supported orientation when you need to rotate.

In Your AppDelegate :

    var orientation: UIInterfaceOrientationMask = .all
    func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
         return orientation
    }

Then in your controller :

 static func SwitchOrientation(orientation : UIInterfaceOrientationMask, viewController : UIViewController){
 
    
    
    if #available(iOS 16.0, *) {
        (UIApplication.shared.delegate as? AppDelegate)?.orientation = orientation
                            
        let windowScene = UIApplication.shared.connectedScenes.first as? UIWindowScene
        windowScene?.requestGeometryUpdate(.iOS(interfaceOrientations: orientation))

        UIApplication.navigationTopViewController()?.setNeedsUpdateOfSupportedInterfaceOrientations()
        
        DispatchQueue.main.async {
                    let windowScene = UIApplication.shared.connectedScenes.first as? UIWindowScene
                    viewController.setNeedsUpdateOfSupportedInterfaceOrientations()
                    viewController.navigationController?.setNeedsUpdateOfSupportedInterfaceOrientations()
                    windowScene?.requestGeometryUpdate(.iOS(interfaceOrientations: orientation)) { error in
                        print(error)
                        print(windowScene?.effectiveGeometry ?? "")
                    }
                }
    

    } else{
        UIDevice.current.setValue(orientation, forKey: "orientation")
    }
  
}
