You need to assign UITapGestureRecogniser to view and dismiss keyboard.

In viewdidLoad()

let tap = UITapGestureRecognizer.init(target: self, action: #selector(self.dismissKeybord(_:)))
        tap.numberOfTapsRequired = 1
        self.view.addGestureRecognizer(tap)

In dismissKeybord

func dismissKeybord(_ sender:UITapGestureRecognizer) {
        self.view.endEditing(true)
}

This worked in my case recently. Should work for you too.

  1. Create a UITapGestureRecognizer.
  2. In the selector method that is endEditing in the below code, simply call self.view.endEditing(true).

(Please note, the parameter true is a value for animated)

class MyViewController: UIViewController {

    override func viewDidLoad() {

        super.viewDidLoad()

        let tapGestureRecognizer = UITapGestureRecognizer(target: self, action:#selector(endEditing))
        tapper.cancelsTouchesInView = false
        self.view.addGestureRecognizer(tapGestureRecognizer)
    }

    func endEditing() {
        self.view.endEditing(true)
    }
}

Working for me. Showing keyboard on touch to textfields. Hide on every other touches.

class LoginController: UIViewController, UITextFieldDelegate {

    @IBOutlet weak var userLogin: UITextField!
    @IBOutlet weak var userPassword: UITextField!

    override func viewDidLoad() {

      userLogin.delegate = self
      userPassword.delegate = self

      //For scrolling the view if keyboard on
      NotificationCenter.default.addObserver(self, selector: #selector(LoginController.keyboardWillShow),
                                             name: NSNotification.Name.UIKeyboardWillShow, object: nil)
      NotificationCenter.default.addObserver(self, selector: #selector(LoginController.keyboardWillHide),
                                             name: NSNotification.Name.UIKeyboardWillHide, object: nil)

      super.viewDidLoad()
    }

    // OTHER METHODS

    var keyBoardAlreadyShowed = false //using this to not let app to scroll view
    //if we tapped UITextField and then another UITextField

    func keyboardWillShow(notification: NSNotification) {
      if !keyBoardAlreadyShowed {
         view.frame.origin.y -= 50
         keyBoardAlreadyShowed = true
      }
    }

    func keyboardWillHide(notification: NSNotification) {
      view.frame.origin.y += 50
      keyBoardAlreadyShowed = false
    }

    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
      view.endEditing(true)
    }
}

You need to set delegates and observers

Swift 3 :-

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        self.view.endEditing(true)
    }

If your touches are not eaten by other view, then i guess this will work 

 override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
            if touches.first != nil {
                view.endEditing(true)
        }
   }
