Converting from UITextField to Int failure - string

Question

I cannot convert the UITextField to an Int, although I have taken a look at the instructions on the internet. I'm a beginner with Swift 2. Can anyone help?
import UIKit
class ViewController: UIViewController {
#IBOutlet var age: UITextField!
#IBOutlet var resultLabel: UILabel!
#IBAction func findAge(_ sender: AnyObject) {
// Changed "enteredAge = age" to "enteredAge = age!"
var age = Int = Int(age.text)
var enteredAge = Int(age)
if enteredAge != nil {
var catYears = enteredAge! * 7
resultLabel.text = "Your cat is \(catYears) in cat years"
} else {
resultLabel.text = "Please enter a number in the box"
}
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}

Answer 1

Entered age use age.text again as in age variable

Answer 2

As I see in your code you are redeclaring the age textfield , I am editing you IBAction . I have not run this code , but I think It will work for you . Just copy paste in your code any check it .
#IBAction func findAge(_ sender: AnyObject) {
var ageToInt = Int(self.age.text!)!
if ageToInt != nil {
var catYears = ageToInt! * 7
resultLabel.text = "Your cat is \(catYears) in cat years"
} else {
resultLabel.text = "Please enter a number in the box"
}
}
Good luck!
