title: SwiftUI: Expanding TextField size to font size before input
body: <p>I'm having a problem with SwiftUI TextField. The cursor and text field size initially is very small, and on input it grows to the full size (in this case .largeTitle). I have made the background black so you can see what is happening to the actual field. Is there a way to set the size of the TextField so the cursor starts off the same size as the text? I have tried all the functions from the documentation with no luck... This is using Xcode 11 Beta 5. Thanks!</p>
  
  <pre><code>TextField("", text: input)
      .lineLimit(nil) // doesn't seem to work in Xcode 11 Beta 5
      .font(.largeTitle)
      .foregroundColor(.blue)
      .background(Color.black)
  </code></pre>
