Answer 1

try like this 

In Swift 2.0, toInt(),replaced with initializers. (In this case, Int(someString).)

 let myString : String = "50"
    let x : Int? = Int(myString)

    if (x != null) {
       // converted String to Int
    }

Answer 2

myString.toInt() - convert the string value into int .
