I hate to add the same function to every UIViewController  By extending UIViewController to support UITextFieldDelegate  you can provide a default behavior of  return pressed     extension UIViewController  UITextFieldDelegate      public func textFieldShouldReturn   textField  UITextField  - gt  Bool           textField resignFirstResponder           return true            When you create new UIViewController and UITextField  all you have to do is to write one line code in your UIViewController   override func viewDidLoad         super viewDidLoad       textField delegate   self     You can even omit this one line code by hooking delegate in Main storyboard   Using  ctrl  and drag from UITextField to UIViewController

you can put this anywhere but not in a UIButton   func TextFieldEndEditing text fiend name  UITextField   - gt  Bool       return  false      then you can put this code in a button also for example    self view endEditing true    this worked for me

The return true part of this only tells the text field whether or not it is allowed to return  You have to manually tell the text field to dismiss the keyboard  or what ever its first responder is   and this is done with resignFirstResponder    like so      Called on  Return  pressed  Return false to ignore   func textFieldShouldReturn   textField  UITextField  - gt  Bool        textField resignFirstResponder       return true

When the user taps the Done button on the text keyboard  a Did End On Exit event will be generated  at that time  we need to tell the text field to give up control so that the keyboard will go away  In order to do that  we need to add an action method to our controller class  Select ViewController swift add the following action method    IBAction func textFieldDoneEditing sender  UITextField    sender resignFirstResponder      Select Main storyboard in the Project Navigator and bring up the connections inspector  Drag from the circle next to Did End On Exit to the yellow View Controller icon in the storyboard and let go  A small pop-up menu will appear containing the name of a single action  the one we just added  Click the textFieldDoneEditing action to select it and that s it

In the view controller you are using     suppose you are using the textfield label as this   IBOutlet weak var emailLabel  UITextField   IBOutlet weak var passwordLabel  UITextField     then your viewdidload should have the code like this override func viewDidLoad             super viewDidLoad            self emailLabel delegate   self         self passwordLabel delegate   self           then you should implement the func named textFieldShouldReturn  func textFieldShouldReturn   textField  UITextField  - gt  Bool           textField resignFirstResponder           return true           -- then  further if you want to close the keyboard when pressed somewhere else on the screen you can implement the following method too   override func touchesBegan   touches  Set lt UITouch gt   with event  UIEvent             self view endEditing true

Another way of doing this which mostly uses the storyboard and easily allows you to have multiple text fields is    IBAction func resignKeyboard sender  AnyObject        sender resignFirstResponder       Connect all your text fields for that view controller to that action on the Did End On Exit event of each field
