Random Image for Launch Screen

I have 3 different images I'd like to use Launch Screen.

I've added a UIImageView in the Launchscreen.storyboard

And I was thinking I could use a simple Switch statement with a randomizer to select the image:

var random = arc4random_uniform(3) //returns 0 to 2 randomly

  switch random {
    case 0:
        launchImageView.image = UIImage(named: "splash1.jpg")
    case 1:
        myImageView.image = UIImage(named: "splash2.jpg")
    default:
        /myImageView.image = UIImage(named: "splash3.jpg")      }

However I'm not really sure where to implement the code as the viewDidLoad will not work.

You can set the UILaunchImageFile by a relative path and then put an image at the path and use your random.

For example you change the launchscreen after launching by setting UILaunchImageFile property in the info.plist. You would then write a random image to the Documents folder.

<key>UILaunchImageFile</key>
<string>../Documents/image.png</string>
