Swift 3 - How to lock orientation for iOS app?

Question

I'm trying to create an app that only supports portrait orientation, I have tried setting at Target -> General -> Deployment Info -> Portrait

Then, at appDelegate.swift

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

AT ViewController.swift

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

But it doesn't work.. At ViewController.swift, it give me error:

Method does not override any method from its superclass

Select a target and find Device Orientation under Deplayment info. — El Tomato, Nov 26 '16 at 06:31
Have you unchecked all other orientations in Deployment Info except for Portrait? — fja, Nov 26 '16 at 06:44
Yes I did, I even clear the landscape out at info.plist --> supported interface orientations — ramen87x, Nov 26 '16 at 07:11
In Swift 3 this functions was replaced by an property. override var supportedInterfaceOrientations : UIInterfaceOrientationMask { return UIInterfaceOrientationMask.portrait } (note the var instead of func) — Thomas G., Nov 26 '16 at 08:20

In Swift 3.1

If you want to lock orientation on all of the screen.

See also https://freakycoder.com/ios-notes-5-how-to-application-orientation-abba750bed6e .

Open AppDelegate.swift, and add this code.

// Lock the orientation to Portrait mode
func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
    return UIInterfaceOrientationMask(rawValue: UIInterfaceOrientationMask.portrait.rawValue)
}

or

// Lock the orientation to Landscape(Horizontal) mode
func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
    return UIInterfaceOrientationMask(rawValue: UIInterfaceOrientationMask.landscape.rawValue)
}

Its a simple code just copy and paste the following code in the ViewController you want to fix the Orientation for.

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

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

This works if and only if all the code is in the ViewController, no need to change anything or put anything in the AppDelegate. Cheers
