title: Xcode simulator text field invisible when vertical
body: <p>I'm just trying out the FoodTracker tutorial on Apple's website.</p>
  
  <p>I just added a text field, label, and button. In the Assistant Editor everything looks fine vertically and horizontally. But in the iPhone 6 simulator, the text field is not showing up when it is vertical. When it's horizontal, it shows up and functions normally.</p>
