Swift 2.0 String to Integer

Question

So I've been trying to convert this string of input numbers into variables but for some reason, every possible combination I try, it always gives me an error

@IBOutlet weak var age: UITextField!
@IBOutlet weak var finalYears: UILabel!
@IBAction func findYears(sender: AnyObject) {

    var enteredYears = age.text.toInt()
    if enteredYears != nil {
        var catYears = enteredYears * 7
        finalYears.text = "Your cat is \(catYears)"
    } else {
        finalYears.text = "Please enter another number"
    }
}

And for some reason on the line

var enteredYears = age.text.toInt()

I always seem to get an error that conflicts with every other line after that piece of code

toInt() returns an optional Int?, since it is possible for the String to Int conversion to fail.

In Swift 2 you have to use the Int initializer instead of .toInt() (returns Int?):

var enteredYears = Int(age.text)
