typealias Balance = (add: ((Int) -> Void), get: (() -> Int), print: () -> ()) //Tupple. Tupple is value type but inside tupple we have function with referenc type.
func newBalance() -> Balance {
    var balance = 0
    return (
        add: { newValue in balance += newValue },
        get: { return balance },
        print: { print("Your balance is \(balance)") }
     )
}

let balance = newBalance()
balance.add(3)  // add 3
balance.get()  // get 3
balance.print() // prints the balance
