title: Get UITextField from UIView using an Identifier/Tag (SWIFT)
body: <p>I need to know how I can access a particular UITextField within a UIView from the ViewController class.</p>
  
  <p>The setup I have currently is that I have ViewController that is linked to a View in Storyboard. I have UIView in nib that has 3 UITextFields. I load the view up using the following code:</p>
  
  <pre><code>TextFieldView = UINib(nibName: "TextView", bundle: nil).instantiateWithOwner(nil, options: nil)[0] as! UIView
  self.view.addSubview(TextFieldView)
  </code></pre>
  
  <p>I can get all three UITextField and their values using the following code:</p>
  
  <pre><code>for case let textField as UITextField in TextView!.subviews {
      print(textField.text)
  }
  </code></pre>
  
  <p>My issue is that how can I get the value of any one particular UITextField using some sort of identifier or a tag. Lets say I have 3 UITextFields named TextField1, TextField2, and TextField3 respectively. How do I get the value of TextField2?</p>
