Add this code to force portrait and lock it:

override func viewDidLoad() {
    super.viewDidLoad()

    // Force the device in portrait mode when the view controller gets loaded
    UIDevice.currentDevice().setValue(UIInterfaceOrientation.Portrait.rawValue, forKey: "orientation") 
}

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

override func supportedInterfaceOrientations() -> Int {

    // Only allow Portrait
    return Int(UIInterfaceOrientationMask.Portrait.rawValue)
}

override func preferredInterfaceOrientationForPresentation() -> UIInterfaceOrientation {

    // Only allow Portrait
    return UIInterfaceOrientation.Portrait
}

In your AppDelegate - set supportedInterfaceOrientationsForWindow to whatever orientations you want the entire application to support:

func application(application: UIApplication, supportedInterfaceOrientationsForWindow window: UIWindow?) -> UIInterfaceOrientationMask {
    return UIInterfaceOrientationMask.All
}
