如何将 CloudKit 数据直接传递到 Text() 而不是列表中

Question

我正在尝试将字符串从数组传递到 Text()，但只能通过先将它传递给列表才能使其工作吗？我已经尝试了 class.struct.item 或 struct.item 等的每种组合，请让我知道如何将它直接传递到 Text() 以在其他视图中使用。

import SwiftUI

struct WorkoutView: View {

    @EnvironmentObject var workoutElements: WorkoutElements
    @State private var newWorkout = WorkoutElement(redWorkout: "")

    var body: some View {
        NavigationView {
            List(workoutElements.workouts) { item in
                VStack {
                    Text(item.redWorkout)
                }
            }

    }
    .onAppear {
        // MARK: fetch from CloudKit
        WorkoutFetcher.fetch { (result) in
            switch result {
            case .success(let newWorkout):
                self.workoutElements.workouts.append(newWorkout)
                print("succesfully fetched Item")
            case .failure(let err):
                print(err.localizedDescription)
            }
        }
    }
 }
}
struct WorkoutView_Previews: PreviewProvider {
    static var previews: some View {
        WorkoutView()
    }
}

// this works for a list
//List(workoutElements.workouts) { item in
    //VStack {
        //Text(item.redWorkout)
    //}
//}
// but this doesn't work for Text()
// Text(workoutElements.workouts.redworkouts)
// Text(workouts.redworkouts)
//etc

Answer 1

如果你只是想把它们连在一起，可以如下（据我看你的模型）

Text("\(workoutElements.workouts.reduce("") { [=10=] + .redWorkout })")

如果需要任何分隔符，则只需替换为

[=11=] + .redWorkout + ". "
