I have coded this

import Cocoa class ViewController: NSViewController {     @IBOutlet weak var textfield: NSTextField! @IBOutlet var label: NSTextField! var name : String    @IBAction func done(_ sender: NSButton) {     name = textfield.stringValue     textfield.isHidden = true     label.isHidden = false     label.stringValue = "Hello, " + name     }  override func viewDidLoad() {     super.viewDidLoad()     label.isHidden = true     label.stringValue = ""     textfield.isEditable = false     textfield.isSelectable = false     }     override var representedObject: Any? {     didSet {     // Update the view, if already loaded.     } }   } 

and it show me this error in line 2:

Class ‘ViewController’ has no initializers
