Saving Game Currency Swift 3.0 Xcode

The output that I am trying to achieve is to save the in game currency so that it's still available when the user re-opens the app. When the user collects more currency, I would like the collected currency to be added to the total currency.

With the code that I have, the currency doesn't save when the app is re-opened.

I am still learning swift so any help / advice would be greatly appreciated!

let totalCoinDefault = UserDefaults.standard()
    totalCoins = totalCoinDefault.integer(forKey: "Totalcoin")
    totalCoinLabel.text = "\(self.totalCoins)"

    func currencyUpdate(_ currentTime: CFTimeInterval){

        if ( coin > 0) {

            totalCoins += self.coin
            totalCoinLabel.text = NSString(format: "Totalcoin : %i", totalCoins) as String

            let totalcoinDefault = UserDefaults.standard()
            totalcoinDefault.setValue(totalCoins, forKey: "Totalcoin")
            totalcoinDefault.synchronize()

        }
    }

You can use this:

let totalCoinDefault = UserDefaults.standard()
totalCoins = totalCoinDefault.integer(forKey: "Totalcoin")
totalCoinLabel.text = "\(self.totalCoins)"

if ( coin > 0) {
    totalCoins += self.coin
    totalCoinLabel.text = String(format: "Totalcoin : %i",totalCoins)
    totalcoinDefault.setValue(totalCoins, forKey: "Totalcoin")
    totalcoinDefault.synchronize()
}

You don't need this func.
