Swift giving Optional(3) instead of 3 for .toInt

Question

Trying to pull a number from a Field and keep getting Optional(number) instead of the number

@IBOutlet weak var years: UITextField!

@IBAction func calculateYear         


        

Answer 1

That happens because the toInt() method returns an optional, to account for the case when the string is not convertible to an integer.

Just put that in an optional binding:

if let a = a {
    println(a)
}
