title: Autofill for UITextField is broken
body: <p>In my sign up form in my app, the keyboard suggests an entry for my first name, last name, eventually a strong password, but not for my email address. I have content-type set to email in the storyboard and in code:</p>
  
  <p><a href="https://i.stack.imgur.com/bxPqF.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/bxPqF.png" alt="enter image description here"></a></p>
  
  <pre><code>self.emailTxt.textContentType = .emailAddress
  </code></pre>
  
  <p>But no suggestion. You can see in the image below, the keyboard suggests the first and last name of the user, but for email it is blank. <a href="https://i.stack.imgur.com/pA5hN.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/pA5hN.jpg" alt="enter image description here"></a></p>
  
  <p>In the next image I show that in signing up for sites on safari, it does suggest my email. Even moreso, it suggests to autofill the entire page:<a href="https://i.stack.imgur.com/4SBlX.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/4SBlX.jpg" alt="enter image description here"></a></p>
  
  <p>What could I be missing?</p>
  
  <h2>EDIT: I created a <a href="https://github.com/PiedPieper/UITextFieldBug" rel="nofollow noreferrer">github repo</a> demonstrating the error. Every field should be auto-filled. What I am experiencing is that in this app, the email works but password doesn't suggest to create a new password. Nothing is working together.</h2>
