public init(_ items: [String], title: String, onSelected: @escaping (Int) -> ()) {
      self.items = items
      self.title = title
      self.onSelected = onSelected
  }

Demo app

Simple app that uses the Floating Segmented Control to switch beetween satellite and standard modes for a MapView.

import FloatingSegmentedControl

struct ContentView: View {
    @State var items = ["Satellite", "Standad"]
    @State var mapType: MKMapType = .hybrid
    
    var body: some View {
        ZStack {
            Map(mapType: $mapType).edgesIgnoringSafeArea(.top)
            VStack {
                FloatingSegmentedControlView(
                  items,
                  title: "Map view",
                  onSelected: onSelected)
                  .padding(.top)
                Spacer()
            }
        }
    }
    
    func onSelected(index: Int) {
        switch index {
        case 0:
            mapType = .hybrid
        case 1:
            mapType = .standard
        default:
