According to Korey Hinton's answer

Swift 2.2:

extension UINavigationController {
    public override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
        return visibleViewController!.supportedInterfaceOrientations()
    }
    public override func shouldAutorotate() -> Bool {
        return visibleViewController!.shouldAutorotate()
    }
}


extension UITabBarController {
    public override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
        if let selected = selectedViewController {
            return selected.supportedInterfaceOrientations()
        }
        return super.supportedInterfaceOrientations()
    }
    public override func shouldAutorotate() -> Bool {
        if let selected = selectedViewController {
            return selected.shouldAutorotate()
        }
        return super.shouldAutorotate()
    }
}

Disable Rotation

override func shouldAutorotate() -> Bool {
    return false
}

Lock to Specific Orientation

override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
    return UIInterfaceOrientationMask.Portrait
}
