在 Swift Tik Tok 克隆中传递视频数组时，ForEach“隐式合成声明”错误:(

如何解决在 Swift Tik Tok 克隆中传递视频数组时，ForEach“隐式合成声明”错误:(

这些错误

“无法声明名为 '$reel' 的实体；'$' 前缀是为隐式合成声明保留的”

“通用结构 'ForEach' 要求 'Binding' 符合 'RandomAccessCollection'”

两个错误都在这个 ForEach

ForEach($reels) { $reel in

          ReelsPlayer(reel: $reel)
}

这是不是因为我的视频是自定义类型，因此 swift 无法识别它们，这给了我“RandomAccessCollection”错误？

我有一个 TabView {}，我正在尝试将每个页面制作成类似于 tik tok 或 vine 的新视频。当我传入虚拟数据时它可以工作，但是当我从我的视频数组中传递时，我得到了这些错误。

视图：

import SwiftUI
import AVKit

struct ReelsView: View {
   
  @State var currentReel = ""
     
  // extracting AVPlayer from media file
  @State var reels: [Reel] = MediaFileJSON.map { item -> Reel in
     
    let url = Bundle.main.path(forResource: item.url,ofType: "MP4") ?? ""
     
    let player = AVPlayer(url: URL(fileURLWithPath: url))
     
    return Reel(player: player,mediaFile: item)
  }
   
  var body: some View {
     
    // setting width and height for rotated view
    GeometryReader { proxy in
       
      let size = proxy.size
       
      // vertical page tab view
      TabView(selection: $currentReel) {
         
        ForEach($reels) { $reel in // **ERRORS HERE**

          ReelsPlayer(reel: $reel)
          // setting width
          .frame(width: size.width)
          .padding()
          // rotate content
          .rotationEffect(.init(degrees: -90))
        }
      }
      // Rotate View
      .rotationEffect(.init(degrees: 90))
      // setting height as width
      .frame(width: size.height)
      .tabViewStyle(PageTabViewStyle(indexDisplayMode: .never))
      // setting max width
      .frame(width: size.width)
       
    }
  }
}

struct ReelsView_Previews: PreviewProvider {
  static var previews: some View {
    ContentView()
  }
}

struct ReelsPlayer: View,Identifiable {
  var id: ObjectIdentifier
   
   
  @Binding var reel: Reel
   
  var body: some View {
     
    ZStack {
       
       
    }
  }
}

媒体文件结构：

struct MediaFile: Identifiable {
  var id = UUID().uuidString
  var url: String
  var title: String
  var isExpanded: Bool = false
}

var MediaFileJSON = [
   
  MediaFile(url: "Reel1",title: "Apple AirTag......."),MediaFile(url: "Reel2",title: "this is the second."),MediaFile(url: "Reel3",title: "the third"),MediaFile(url: "Reel4",title: "wooooooooooooo ya"),MediaFile(url: "Reel5",title: "ay ayayayayay ayay lsdfk sl"),MediaFile(url: "Reel6",title: "this is the last one....."),]

卷轴结构：

struct Reel: Identifiable {
   
  var id: String = UUID().uuidString
  var player: AVPlayer?
  var mediaFile: MediaFile
}
