Close iOS Keyboard Using Swift

There are two ways to close iOS keyboard.

1. Close the virtual keyboard while finishing typing at any textField

func textFieldShouldReturn(_ textField: UITextField) -> Bool {
    textField.resignFirstResponder()
    return true
}

2. Close the virtual keyboard while one or more fingers touch down in a view or window

Assume that finish typing in passwordFiled.

@IBOutlet weak var passwordField: UITextField!

Add passwordField.delegate = self to function viewDidLoad.

override func viewDidLoad() {
    super.viewDidLoad()    
    passwordField.delegate   = self
}

Add a function touchesBegan.

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

That’s it!
