提升应用程序的用户体验：在 iOS 17 的 SwiftUI 中探索 ScrollViewscrollTransition API

借助 SwiftUI，设计和实现复杂的 UI 已变得轻而易举。

ScrollView 当需要滚动功能时，开发人员通过添加子视图来使用设计屏幕。

import SwiftUI

struct Movie: Identifiable {
  let id = UUID()
  let title: String
  let color: Color
  
  static let dummyMovies: [Movie] = [
    Movie(title: "a.square.fill", color: .red),
    Movie(title: "b.circle", color: .green),
    Movie(title: "c.square.fill", color: .blue),
    Movie(title: "d.circle", color: .yellow),
    Movie(title: "e.square.fill", color: .gray),
    Movie(title: "f.circle", color: .purple),
  ]
}

struct ContentView: View {
  var body: some View {
    ScrollView {
      ForEach(Movie.dummyMovies) { movie in
        Image(systemName: movie.title)
          .resizable()
          .imageScale(.large)
          .frame(height: 340)
          .cornerRadius(16)
