在call SwiftUI中位置#11，#12处的额外参数

Question

我继续在SwiftUI中的切换开关上得到一个“在第11位，第12位的额外参数”错误。我见过其他人有“电话中的额外论点”错误，但答案似乎没有帮助；此外，我的错误说“第11，12位”，这是我从未见过的其他人。我正在使用Xcode 12测试版，如果这有区别的话。

import SwiftUI

let defaults = UserDefaults.standard

let notifsEnabled = defaults.bool(forKey: "NotifsEnabled")




struct Settings: View {
    @State var class11: String = defaults.string(forKey: "class11") ?? ""
    @State var class12: String = defaults.string(forKey: "class12") ?? ""
    @State var class13: String = defaults.string(forKey: "class13") ?? ""
    @State var class14: String = defaults.string(forKey: "class14") ?? ""
    
    @State var class21: String = defaults.string(forKey: "class21") ?? ""
    @State var class22: String = defaults.string(forKey: "class22") ?? ""
    @State var class23: String = defaults.string(forKey: "class23") ?? ""
    @State var class24: String = defaults.string(forKey: "class24") ?? ""
    
    @State var scheduleNotifications = notifsEnabled
    
    
    
    var body: some View {
        
        VStack(alignment: .leading) {
            
            Toggle(isOn: $scheduleNotifications) { //Extra arguments at positions #11, #12 in call
                Text("Daily schedule notifications")
            }
            
            if scheduleNotifications {
                Text(CreateNotifs())
            } else {
                Text(DeleteNotifs())
            }
            
            
            
            Text("This App will send you a reminder each day at 8:25 with the schedule for that day")
                .font(.caption)
                .foregroundColor(Color.gray)
            
            
            Divider()
            
            TextField("Class 1-1", text: $class11)
            
            TextField("Class 1-2", text: $class12)
            
            TextField("Class 1-3", text: $class13)
            
            TextField("Class 1-4", text: $class14)
            
            TextField("Class 2-1", text: $class21)
            
            TextField("Class 2-2", text: $class22)
            
            TextField("Class 2-3", text: $class23)
            
            TextField("Class 2-4", text: $class24)
            
            
            
            //Spacer()
        }
        .padding()
        .navigationBarTitle("Settings")
        
    }
    
}

ViewBuilder只支持一个容器中最多10个静态视图.这是你犯错的原因之一

把他们分组

Group {

    TextField("Class 1-1", text: $class11)
    
    TextField("Class 1-2", text: $class12)
    
    TextField("Class 1-3", text: $class13)
    
    TextField("Class 1-4", text: $class14)
    
    TextField("Class 2-1", text: $class21)
    
    TextField("Class 2-2", text: $class22)
    
    TextField("Class 2-3", text: $class23)
    
    TextField("Class 2-4", text: $class24)

}
