Convert Int to String in Swift

I'm trying to work out how to cast an Int into a String in Swift.

I figure out a workaround, using NSNumber but I'd love to figure out how to do it all in Swift.

let x : Int = 45
let xNSNumber = x as NSNumber
let xString : String = xNSNumber.stringValue

Converting Int to String:

let x : Int = 42
var myString = String(x)

And the other way around - converting String to Int:

let myString : String = "42"
let x: Int? = myString.toInt()

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

Or if you're using Swift 2 or 3:

let x: Int? = Int(myString)

Check the Below Answer:

let x : Int = 45
var stringValue = "\(x)"
print(stringValue)
