swift UI使用Relam返回重复记录

我使用Relam在本地存储数据，工作正常，但当我尝试添加带有导航链接的新记录时，它也会返回重复记录。另一个问题是，当我单击记录时，我希望更改导航，但由于它有重复的记录，第一个记录不起作用，但第二个记录起作用。

这是模型。

import SwiftUI
import RealmSwift

struct Task: Identifiable {
    var id: String
    var title: String
    var completed: Bool = false
    var completedAt: Date = Date()

    init(taskObject: TaskObject) {
            self.id = taskObject.id.stringValue
            self.title = taskObject.title
            self.completed = taskObject.completed
            self.completedAt = taskObject.completedAt
        }
}

这是持久模型。。。

import Foundation
import RealmSwift

class TaskObject: Object {
    @Persisted(primaryKey: true) var id: ObjectId
    @Persisted var title: String
    @Persisted var completed: Bool = false
    @Persisted var completedAt: Date = Date()
}

这是视图模型。。

final class TaskViewModel: ObservableObject {
    // 3
    @Published var tasks: [Task] = []
    // 4
    private var token: NotificationToken?

    init() {
        setupObserver()
    }

    deinit {
        token?.invalidate()
    }
    // 5
    private func setupObserver() {
        do {
            let realm = try Realm()
            let results = realm.objects(TaskObject.self)

            token = results.observe({ [weak self] changes in
                // 6
                self?.tasks = results.map(Task.init)
                    .sorted(by: { $0.completedAt > $1.completedAt })
                    .sorted(by: { !$0.completed && $1.completed })
            })
        } catch let error {
            print(error.localizedDescription)
        }
    }
    // 7
    func addTask(title: String) {
        let taskObject = TaskObject(value: [
            "title": title,
            "completed": false
        ])
        do {
            let realm = try Realm()
            try realm.write {
                realm.add(taskObject)
            }
        } catch let error {
            print(error.localizedDescription)
        }
    }
    // 8
    func markComplete(id: String, completed: Bool) {
        do {
            let realm = try Realm()
            let objectId = try ObjectId(string: id)
            let task = realm.object(ofType: TaskObject.self, forPrimaryKey: objectId)
            try realm.write {
                task?.completed = completed
                task?.completedAt = Date()
            }
        } catch let error {
            print(error.localizedDescription)
        }
    }

    func remove(id: String) {
        do {
            let realm = try Realm()
            let objectId = try ObjectId(string: id)
            if let task = realm.object(ofType: TaskObject.self, forPrimaryKey: objectId) {
                try realm.write {
                    realm.delete(task)
                }
            }
        } catch let error {
            print(error.localizedDescription)
        }
    }

    func updateTitle(id: String, newTitle: String) {
        do {
            let realm = try Realm()
            let objectId = try ObjectId(string: id)
            let task = realm.object(ofType: TaskObject.self, forPrimaryKey: objectId)
            try realm.write {
                task?.title = newTitle
            }
        } catch let error {
            print(error.localizedDescription)
        }
    }
}

这是主视图。。

@main
struct RelamDemoSwiftUIApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView().environmentObject(TaskViewModel())

        }
    }
}

这是内容视图的代码。。

import SwiftUI

struct ContentView: View {
    var body: some View {
            NavigationView {
                VStack {
                    AddTaskView()
                    TaskListView()
                }
                .navigationTitle("Todo")
                .navigationBarTitleDisplayMode(.automatic)
            }
        }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

以下是添加任务视图的代码。。

import SwiftUI

struct AddTaskView: View {
    @State private var taskTitle: String = ""
    @EnvironmentObject private var viewModel: TaskViewModel

    var body: some View {
        HStack(spacing: 12) {
            TextField("Enter New Task..", text: $taskTitle)
            Button(action: handleSubmit) {
                Image(systemName: "plus")
            }
        }
        .padding(20)
    }

    private func handleSubmit() {
        viewModel.addTask(title: taskTitle)
        taskTitle = ""
    }
}

这是任务列表视图。。

struct TaskListView: View {
    @EnvironmentObject private var viewModel: TaskViewModel
    var body: some View {

        ScrollView {
            
            LazyVStack (alignment: .leading) {
                ForEach(viewModel.tasks, id: \.id) { task in
                    TaskRowView(task: task)
                    Divider().padding(.leading, 20)
                    NavigationLink (destination: TaskView(task: task)) {
                        TaskRowView(task: task)

                }.animation(.default)
                }
            }
        }
    }
}

这是任务代码。。

struct TaskView: View {
    // 1
    @EnvironmentObject private var viewModel: TaskViewModel
    // 2
    @Environment(\.presentationMode) var presentationMode: Binding<PresentationMode>
    @State private var taskTitle: String = ""
    // 3
    let task: Task

    var body: some View {
        VStack(alignment: .leading, spacing: 24) {
            // 4
            VStack(alignment: .leading, spacing: 4) {
                Text("Title")
                    .foregroundColor(Color.gray)
                TextField("Enter title..", text: $taskTitle)
                    .font(.largeTitle)
                Divider()
            }
            // 5
            Button(action: deleteAction) {
                HStack {
                    Image(systemName: "trash.fill")
                    Text("Delete")
                }
                .foregroundColor(Color.red)
            }
            Spacer()
        }
        .navigationBarTitle("Edit Todo", displayMode: .inline)
        .padding(24)
        .onAppear(perform: {
            taskTitle = task.title
        })
        // 6
        .onDisappear(perform: updateTask)
    }

    private func updateTask() {
        viewModel.updateTitle(id: task.id, newTitle: taskTitle)
    }

    private func deleteAction() {
        viewModel.remove(id: task.id)
        presentationMode.wrappedValue.dismiss()
    }
}
