Answer 1

Here is a simple way that works for me with Swift 4.2 (iOS 12.2), put this in a UIViewController for which you want to disable shouldAutorotate:

override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
    return .portrait
}

The .portrait part tells it in which orientation(s) to remain, you can change this as you like. Choices are: .portrait, .all, .allButUpsideDown, .landscape, .landscapeLeft, .landscapeRight, .portraitUpsideDown.
