Adding a double-click gesture recognizer in Swift

The click recognizer is done, but I can't figure out how to change that click recognizer to double-click.

Code:

import Foundation
import UIKit
 
class MainBoardController: UIViewController{
 
  let tap = UITapGestureRecognizer()
 
  override func viewDidLoad() {
    ()
    // Do any additional setup after loading the view,typically from a nib.
    var swipe: UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self,action: "GotoProfile")
     = 
          (swipe)
 
    (self,action: "GotoCamera")
     = true
    (tap)
  }
 
  override func didReceiveMemoryWarning() {
    ()
    // Dispose of any resources that can be recreated.
  }
 
  func GotoProfile(){
    ("Profilesegue",sender: nil)
  }
 
  func GotoCamera(){
    ("Camerasegue",sender: nil)
  }
}

Solution

Finally, the extension solved this problem:

override func viewDidLoad() {
  ()
 
  let tapGR = UITapGestureRecognizer(target: self,action: #selector((_:)))
   = self
   = 2
  (tapGR)
}
extension MainBoardController: UIGestureRecognizerDelegate {
  func handleTap(_ gesture: UITapGestureRecognizer){
    print("doubletapped")
  }
}
