ios - 无法在 SwiftUI 的当前上下文中推断闭包类型

Question

我正在尝试在 SwiftUI 中使用 ForEach 将简单的字符串数组传递到列表中。

• 这是我的代码

  import SwiftUI
  
  struct ContentView : View {
  var testArry:[String] = ["1", "a", "c"]
  var body: some View {
  List {
      ForEach(testArry) { obj in
          Text("test")
      }
    }
  }
  }
  
  #if DEBUG
  
  struct ContentView_Previews : PreviewProvider {
   static var previews: some View {
     ContentView()
   }
  }
  #endif
  

Error : Unable to infer closure type in the current context

或者你可以像这样使用 .identified(by:\.self) :

import SwiftUI

struct ContentView : View {

    var testArry:[String] = ["1", "a", "c"]

    var body: some View {
        List {
            ForEach(testArry.identified(by: \.self)) { obj in
                Text("test")
            }
        }
    }
}
