Dismiss Keyboard on Touch

If you want to dismiss the keyboard when you touch anywhere outside a text field, choose one of these ways:

Dismiss keyboard in a view with no scrollview/tableview

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

(Note: This will not work on a scrollview or tableview.)

Dismiss keyboard when touching inside a scrollview/tableview

1. Add a TapGestureRecognizer to your storyboard's scene
2. Create an action outlet in your viewcontroller with the code below

 
@IBAction func TapGestureRecognizer_Action(_ sender: UITapGestureRecognizer) {
    view.endEditing(true)
}
 

All in code

 
override func viewDidLoad() {
    super.viewDidLoad()
    
    let tapGesture = UITapGestureRecognizer(target: self, action: #selector(self.endEditing))
    view.addGestureRecognizer(tapGesture)
}

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