PagingView-example.swift

struct PagingContentView: View {
  @State var currentPage: Int = 0
  let config: PagingViewConfig

  init() {
    var config = PagingViewConfig()
    config.direction = .horizontal
    config.size = 100
    config.margin = 0
    config.spacing = 0
    self.config = config
  }

  var body: some View {
    PagingView(config: config, page: $currentPage, views: Array(0...30).map { page(at: $0) })
  }

  @ViewBuilder
  func page(at index: Int) -> some View {
    Text("Page \(index)")
      .frame(maxWidth: .infinity, maxHeight: .infinity)
      .background(backgroundColor(at: index))
  }

  func backgroundColor(at index: Int) -> Color {
    let indexMod = (index % 3)
    switch indexMod {
    case 0: return Color.red
    case 1: return Color.green
    case 2: return Color.blue
    default: return Color.clear
    }
  }
