Make sure your UITextField delegates are set and the tags are incremented properly. This can also be done through the Interface Builder.

Here's a link to an Obj-C post I found: How to navigate through textfields (Next / Done Buttons)

class ViewController: UIViewController,UITextFieldDelegate {
   // Link each UITextField (Not necessary if delegate and tag are set in Interface Builder)
   @IBOutlet weak var someTextField: UITextField!

   override func viewDidLoad() {
      super.viewDidLoad()
      // Do the next two lines for each UITextField here or in the Interface Builder
      someTextField.delegate = self
      someTextField.tag = 0 //Increment accordingly
   }

   func textFieldShouldReturn(_ textField: UITextField) -> Bool {
      // Try to find next responder
      if let nextField = textField.superview?.viewWithTag(textField.tag + 1) as? UITextField {
         nextField.becomeFirstResponder()
      } else {
         // Not found, so remove keyboard.
         textField.resignFirstResponder()
      }
      // Do not add a line break
      return false
   }
}
