@IBAction func endTurn(sender: UIButton!) {
    if coins.count > 0 { // @IBOutlet var coins: [UIButton]! (21 coins)
        let index: Int = Int(arc4random_uniform(UInt32(coins.count)))
        coins[index].hidden = true
        self.coins.removeAtIndex(index)
        if coins.isEmpty {
            println("GameOver")
        }
    }
}

Try this

let numberToDelete = Int(arc4random_uniform(UInt32(3))) + 1

for i in 0..<numberToDelete{
    let indexToDelete = Int(arc4random_uniform(UInt32(coins.count)))
    coins.removeAtIndex(indexToDelete)
    if coins.isEmpty{
        break;
    }
}
if coins.isEmpty{
    println("GameOver")
}
