I imported both of the following protocols:

@interface ViewController : UIViewController&

@JRo solution works great!

Here is my updated code in Swift 3:

func textFieldDidBeginEditing(_ textField: UITextField) {
    self.activeTextField = textField

    // Create a date picker for the date field.
    let picker = UIDatePicker()
    picker.datePickerMode = .date
    picker.addTarget(self, action: #selector(updateDateField(sender:)), for: .valueChanged)

    // If the date field has focus, display a date picker instead of keyboard.
    // Set the text to the date currently displayed by the picker.
    textField.inputView = picker
    textField.text = formatDateForDisplay(date: picker.date)
}


// Called when the date picker changes.

func updateDateField(sender: UIDatePicker) {
    activeTextField?.text = formatDateForDisplay(date: sender.date)
}


// Formats the date chosen with the date picker.

fileprivate func formatDateForDisplay(date: Date) -> String {
    let formatter = DateFormatter()
    formatter.dateFormat = "dd MMM yyyy"
    return formatter.string(from: date)
}
