Random number from an array without repeating the same number twice in a row?

Question

I am making a game using Swift and SpriteKit where i move an object to random locations based on an array.

The array that is made up of CGPoints:

let

I think Larme's suggestion is pretty clever, actually.

easyArray.append(easyArray.removeAtIndex(Int(arc4random_uniform(UInt32(easyArray.count)-1))))
selector.runAction(SKAction.moveTo(easyArray.last!, duration: 0))
