My entire app is portrait mode. However, one screen needs to be able to rotate to landscape (for playing video). I am able to enable all orientation rotations with no problem via @Jonathan Danek's answer.

In my AppDelegate I have:

static var orientationLock = UIInterfaceOrientationMask.portrait

and subsequently:

func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
    return AppDelegate.orientationLock
}

So to enable rotation for all orientations, I do the following as the video view-controller is presented: 

AppDelegate.orientationLock = UIInterfaceOrientationMask.all
UINavigationController.attemptRotationToDeviceOrientation()

This works great ..the problem is when I try to change it back to only portrait mode.

I am trying this as the video view-controller is dismissed:

AppDelegate.orientationLock = UIInterfaceOrientationMask.portrait
UINavigationController.attemptRotationToDeviceOrientation()

..but it does not trigger the above AppDelegate's supportedInterfaceOrientationsForWindow function if the video view-controller is currently rotated to Landscape. What's interesting is that it will trigger the function if the video view-controller is currently rotated to Portrait.

So I'm wondering how I can set my one view-controller to have all orientations, but then change it back to just portrait?

Have you tried to overwrite supportedInterfaceOrientations in your controller? That might help.

Example:

override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
    return UIInterfaceOrientationMask.all
}

Returns all of the interface orientations that the view controller supports.

Apple Doc - supportedInterfaceOrientations

Swift 5.1 short version:

override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
    .all
}
