title: SwiftUI Optional TextField
body: <p>Can SwiftUI Text Fields work with optional Bindings? Currently this code:</p>
  
  <pre><code>struct SOTestView : View {
      @State var test: String? = "Test"
  
      var body: some View {
          TextField($test)
      }
  }
  </code></pre>
  
  <p>produces the following error:</p>
  
  <blockquote>
    <p>Cannot convert value of type 'Binding&lt; String?>' to expected argument type 'Binding&lt; String>'</p>
  </blockquote>
  
  <p>Is there any way around this? Using Optionals in data models is a very common pattern - in fact it's the default in Core Data so it seems strange that SwiftUI wouldn't support them</p>
