Answer 1

When you use UIApplication.shared.statusBarOrientation, Xcode 11 will show the warning 'statusBarOrientation' was deprecated in iOS 13.0: Use the interfaceOrientation property of the window scene instead.

This answer is in Swift 5, and supports both iOS 13 and lower versions. It assumes the following:

• You will create only one scene, and never more than one
• You wish to contain your code to a specific view
• You have a view that has a member variable previewLayer of type AVCaptureVideoPreviewLayer

First, in your SceneDelegate.swift, add the following lines:

    static var lastCreatedScene: UIWindowScene?

    func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
        guard let newScene = (scene as? UIWindowScene) else { return }
        Self.lastCreatedScene = newScene
    }

Then in your view, add the following function and call it in layoutSubviews():

    func refreshOrientation() {
        let videoOrientation: AVCaptureVideoOrientation
        let statusBarOrientation: UIInterfaceOrientation
        if #available(iOS 13, *) {
            statusBarOrientation = SceneDelegate.lastCreatedScene?.interfaceOrientation ?? .portrait
        } else {
            statusBarOrientation = UIApplication.shared.statusBarOrientation
        }
        switch statusBarOrientation {
        case .unknown:
            videoOrientation = .portrait
        case .portrait:
            videoOrientation = .portrait
        case .portraitUpsideDown:
            videoOrientation = .portraitUpsideDown
        case .landscapeLeft:
            videoOrientation = .landscapeLeft
        case .landscapeRight:
            videoOrientation = .landscapeRight
        @unknown default:
            videoOrientation = .portrait
        }
        self.previewLayer.connection?.videoOrientation = videoOrientation
    }
