title: Get value of a Binding
body: <p>I am trying to create <code>@State</code> variable inside a custom initialiser based on a binding that is passed in.  I am getting error <code>Cannot convert value of type 'Binding&lt;Color&gt;' to expected argument type 'Color'</code>. Is there a way to extract raw value of the biding itself? This is an example:</p>
  <pre><code>struct ContentView: View {
      
      @State var color = Color.red
      
      var body: some View {
          
          SomeView(color: $color)
      }
  }
  
  struct SomeView: View {
      
      @Binding var color: Color
      @State var someOtherColor: Color
      
      init(color: Binding&lt;Color&gt;) {
          
          _color = color
          
          _someOtherColor = State(initialValue: color) // ERROR: Cannot convert value of type 'Binding&lt;Color&gt;' to expected argument type 'Color'
      }
      
      var body: some View {
          Text(&quot;Hello, world!&quot;)
      }
  }
  </code></pre>
