recently starting learning swift and I'm getting an error message that I'm not sure where to being with. I'm attempting to make a simple app that stores the user phone number in UserDefaults. I'm not sure if the location of where I've placed the code or another silly mistake. Thanks in advance for any help.
View Controller:
class ViewController: UIViewController {
@IBOutlet var userNumberText: UITextField!
@IBOutlet var blankView: UITextView!
@IBAction func saveButton(_ sender: Any) {
if(userNumberText.text?.count)! > 0 {
let number = UserDefaults.standard.set(userNumberText.text, forKey: "number")
}
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
let defaults = UserDefaults.standard
if let number = defaults.string(forKey: "number"){
blankView.text = number;
}
}
}
