我建立了一个核心数据模型，其中包含3个实体：Exercise、ExerciseSet和Workout。它的设置使得Exercise和ExerciseSet具有一对一关系，而Workout和ExerciseSet具有一对多关系。我试图通过Workout访问ExerciseSet中的属性，但当我运行以下代码时：

struct WorkoutView: View {
@State var workout = Workout()
    
    var body: some View {
        
        Text("Sets in Workout: \(workout.exerciseSets.count)")
        
        ForEach(Array(arrayLiteral: workout.exerciseSets), id: \.self) { e in
            Text("Exercise Name: \(e.exercise.exercisename), Reps: \(e.reps), Weight: \(e.weight)")         
        }

我收到以下错误

Value of type 'NSSet' has no member 'exercise'
Value of type 'NSSet' has no member 'reps'
Value of type 'NSSet' has no member 'weight'

当我在健身程序和健身程序之外调用这些属性时，它们都存在。exerciseSets.count按预期返回。
以下是每个实体的定义：

为了能够通过“健身程序”访问ExerciseSet中的属性，我是否遗漏了什么？谢谢。
