Ios SwiftUI Bug Fix"；无法转换类型为'；装订<；int>'；到预期类型'；装订<_>'&引用；

我遇到此错误的问题：

“无法将“Binding”类型的值转换为预期的“Binding”类型”

我想我用的是一个过时的SwiftUI版本，但我不是100%确定，所以我能得到的任何帮助都会很棒

我在下面显示了我的代码，以便您可以查看

我不确定底部是否重要，但我添加它只是为了安全

ContentView

import SwiftUI

struct ContentView: View {
    @State private var selection = 0
    @State var networkManager = NetworkManager()
    var body: some View {
        TabView(selection: $selection){

            NavigationView{
            Text("First View")
                .font(.title)
                    .navigationBarTitle(Text("Welcome"))
                }

谢谢

显示的错误非常混乱，但其他一些错误会导致此类错误

在您的情况下，可能需要修复

选项卡视图

中的第二个

导航视图

：

            NavigationView{
                //↓Fix this line.
                List(networkManager.featureList.results, id: \.url) { featured in
                    Text(featured.name.capitalized)
                }
                .navigationBarTitle(Text("Featured"))
            }
            .tabItem {
                VStack {
                    Image(systemName: "app.badge.fill")
                    Text("Featured")
                }
            }
            .tag(1)

最好检查并始终尝试查找最新的示例或教程。

欢迎使用Stackoverflow

OOPer实际上是正确的。您需要修复

列表

。 让我们尝试替换

列表中的数据

，以查看项目将编译：

假设我们有一个符合

可识别的
协议的模型，如下所示：

struct Person: Identifiable {
    var id = UUID()
    var name: String
}

然后将您的
列表
行替换为以下内容：

List([Person(name: "fafa")]) { featured in
    Text(featured.name)
}

这次它应该运行。由于SwiftUI是新的，这一定是导致错误相当混乱的原因
