I have a working solution based on this answer here: https://stackoverflow.com/a/24928474/1359306

  1. So first off, make sure the supported orientations are checked in Target Settings > General > Deployment Info.

Target Settings > General > Deployment Info

  1. Add this code (taken from the linked answer) to your app delegate:

    internal var shouldRotate = false
func application(application: UIApplication, supportedInterfaceOrientationsForWindow window: UIWindow?) -> UIInterfaceOrientationMask {
  if shouldRotate {
    return .AllButUpsideDown
  } else {
    return .Portrait
  }
}

  2. Then in your landscape only view controller, put the following code in viewDidAppear (NOT viewDidLoad!) to enable both portrait and landscape view:

    let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
appDelegate.shouldRotate = true

  3. And the opposite to viewWillDisappear to disable landscape again.

    let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
appDelegate.shouldRotate = false

  4. I am also hiding my tabs and status bar when the app is in landscape, which feels like a much better UX than tapping a tab and automatically rotating the screen.

There are a few things which in my case I don't have to worry about.

  • Displaying a modal view from a landscape view would cause issues
