## Discussion

Discussion Use this modifier to combine a View and a ViewModifier, to create a new view. For example, if you create a view modifier for a new kind of caption with blue text surrounded by a rounded rectangle: struct BorderedCaption: ViewModifier {     func body(content: Content) -> some View {         content             .font(.caption2)             .padding(10)             .overlay(                 RoundedRectangle(cornerRadius: 15)                     .stroke(lineWidth: 1)             )             .foregroundColor(Color.blue)     } } You can use modifier(_:) to extend View to create new modifier for applying the BorderedCaption defined above: extension View {     func borderedCaption() -> some View {         modifier(BorderedCaption())     } } Then you can apply the bordered caption to any view: Image(systemName: "bus")     .resizable()     .frame(width:50, height:50) Text("Downtown Bus")     .borderedCaption()
