title: How to change radius of segmented control in swiftUI without using old UISegmentControl
body: <p>I was trying to change radius of segment control in SwiftUI. I am only able to change the outer radius. Is there any way to change the radius of selected tag?</p>
  
  <pre><code>struct ContentView: View {
      @State private var favoriteColor = 0
      var colors = ["Red", "Green", "Blue"]
  
      var body: some View {
          VStack {
              Picker(selection: $favoriteColor, label: Text("What is your favorite color?")) {
                  ForEach(0..&lt;colors.count) { index in
                      Text(self.colors[index]).tag(index)
                  }
              }.pickerStyle(SegmentedPickerStyle())
               .cornerRadius(13). ////////////////////////////////--
  
              Text("Value: \(colors[favoriteColor])")
          }
      }
  }
  </code></pre>
