I have a simple app in SwiftUI, and I try to delete all list items with context menu , when I click context menu button, I want to remove all items, is it possible? struct MyView: View { @State private var selectedUsers: MyModel? var body: some View { ScrollView(.vertical, showsIndicators: false, content: { VStack(content: { ForEach(datas){ data in MyRowView(data: data) .contextMenu { Button(action: { self.delete(item: data) }) { Text("delete") } } .onTapGesture { selectedUsers = data } } .onDelete { (indexSet) in selectedUsers.remove(atOffsets: indexSet) }}) })} private func delete(item data: MyModel) { if let index = datas.firstIndex(where: { $0.id == data.id }) { datas.remove(at: index) } }} model: struct MyModel: Identifiable, Hashable, Codable { var id = UUID().uuidString var name: String } var datas = [ MyModel(name: "david"), MyModel(name: "marry"), ]

I have list items in SwiftUI, and when I delete list items I want to delete after alert menu, like "do want to delete your list items, ""yes" or "no" is it possible? struct MyView: View { @State private var selectedUsers: MyModel? var body: some View { ScrollView(.vertical, showsIndicators: false, content: { VStack(content: { ForEach(datas){ data in MyRowView(data: data) .contextMenu { Button(action: { self.delete(item: data) }) { Text("delete") } } .onTapGesture { selectedUsers = data } } .onDelete { (indexSet) in self.datas.remove(atOffsets: indexSet) }}) })} private func delete(item data: MyModel) { if let index = datas.firstIndex(where: { $0.id == data.id }) { datas.remove(at: index) } }}

I have list items in SwiftUI, and when I delete list items, but when I click the delete button, it delete item randomly, I want to delete seleted item, where is the mistake? struct MyView: View { @State private var selectedUsers: MyModel?   @State var datas: [MyModel]    @State private var confirmDelete = false var body: some View { ScrollView(.vertical, showsIndicators: false, content: { VStack(content: { ForEach(datas){ data in MyRowView(data: data) .contextMenu { Button(action: { self.delete(item: data) }) { Text("delete") } } .onTapGesture { selectedUsers = data }   .confirmationDialog( "Are you sure ?",                   isPresented: $confirmDelete,                   titleVisibility: .visible                 ){                                       Button(role: .destructive) {                     self.delete(item: data)                   } label: {                     Text("ok")                                         }                   Button(role: .cancel) {                                         } label: {                     Text("cancel")                                         }                 }             } .onDelete { (indexSet) in self.datas.remove(atOffsets: indexSet) }}) })} private func delete(item data: MyModel) { if let index = datas.firstIndex(where: { $0.id == data.id }) { datas.remove(at: index) } }}

I am trying to use confirmationDialog to delete an item in a List. But what happens is that the wrong item gets deleted. Why? Here is my code: struct MyView: View { @State private var selectedUsers: MyModel?   @State var datas: [MyModel]    @State private var confirmDelete = false var body: some View { ScrollView(.vertical, showsIndicators: false, content: { VStack(content: { ForEach(datas){ data in MyRowView(data: data) .contextMenu { Button(action: { self.delete(item: data) }) { Text("delete") } } .onTapGesture { selectedUsers = data }   .alert(isPresented: $confirmDelete) {               Alert(title: Text("title"),                 message: Text("message"),                 primaryButton: .destructive(Text("Delete")) {                                 self.delete(item: data)                                   },                 secondaryButton: .cancel())             }                               } .onDelete { (indexSet) in self.datas.remove(atOffsets: indexSet) }}) })} private func delete(item data: MyModel) { if let index = datas.firstIndex(where: { $0.id == data.id }) { datas.remove(at: index) } }}

I have small SwiftUI app, and it throw an error like "Cannot find 'state' in scope" for this line  Register(state: state) I guess it must be like that, but it is throw an error, I do not know what I missed? Any idea? struct Register: View {       @ObservedObject private var viewModel: RegisterViewModel        init(state: AppState) {    self.viewModel =RegisterViewModel(authAPI: AuthService(), state: state)    }       var body: some View { } } struct Register_Previews: PreviewProvider {       @ObservedObject private var viewModel: RegisterViewModel   @State var pushActive = false        init(state: AppState) {    self.viewModel = RegisterViewModel(authAPI: AuthService(), state: state)    }       static var previews: some View {     Register(state: state)   } } class RegisterViewModel: ObservableObject {     @Published var state: AppState       init(authAPI: AuthAPI, state: AppState) {     self.authAPI = authAPI     self.state = state   }     } }

I have small problem in my project, it throw an error as a Extra arguments at positions #3, #4 for  Auth.auth().signIn() line, I do not know what I missed? func login(email: String, password: String, name: String, surname: String) -> Future<User?, Never> { return Future<User?, Never> { promise in Auth.auth().signIn(withEmail: email, password: password, name: name, surname: surname) {(authResult, _) in guard let id = authResult?.user.providerID, let email = authResult?.user.email else { promise(.success(nil)) return } let user = User(id: id, email: email, name:name, surname:surname) promise(.success(user)) } } } model: import Foundation struct User { let id: String let email: String let name: String let surname: String }

I ask this question before, it was answered but it is not work for many data, like when I click the any list items, all details pass name of "david", I want to pass data of user which I clicked, where I missed here? struct ImageModel: Identifiable, Hashable {   var id = UUID().uuidString   var name: String   } var datas = [       ImageModel(name: "davis"),  ImageModel(name: "carry"),   ImageModel(name: "maria"), ] struct ImageRowView: View {   var data: ImageModel   var body: some View {            NavigationLink(destination: ImageDetailsView(data: ImageModel)){                       HStack{} }}} struct ImageDetailsView: View {      var body: some View {          ImageDetails(data:  ImageModel(name: "davis"))   } } struct ImageDetailsView_Previews: PreviewProvider {   static var previews: some View {           ImageDetailsView()         } } struct ImageDetails : View {      var data: ImageModel   var body: some View{   VStack{             Text(data.name)                      } }

I have multiple alert dialog in project, just one of them is work, but I am still do not know why I am not use second one, so how we can use multiple .alert dialog in SwiftUI? struct MyView: View { @State private var selectedUsers: MyModel?   @State var datas: [MyModel]    @State private var deleteRow = false   @State private var deleteRows = false var body: some View { ScrollView(.vertical, showsIndicators: false, content: { VStack(content: { ForEach(datas){ data in MyRowView(data: data) .contextMenu { Button(action: {     deleteRow = true }) { Text("delete") } Button(action: {    deleteRows = true }) { Text("delete") } } .onTapGesture { selectedUsers = data }   .alert(isPresented: $deleteRow) {               Alert(title: Text("title"),                 message: Text("message"),                 primaryButton: .destructive(Text("Delete")) {                                 self.delete(item: data)                                   },                 secondaryButton: .cancel())             }   .alert(isPresented: $deleteRows) {               Alert(title: Text("title"),                 message: Text("message"),                 primaryButton: .destructive(Text("Delete")) {                    self.datas.removeAll()                 },                 secondaryButton: .cancel())             }                               } .onDelete { (indexSet) in self.datas.remove(atOffsets: indexSet) }}) })} private func delete(item data: MyModel) { if let index = datas.firstIndex(where: { $0.id == data.id }) { datas.remove(at: index) } }}

I have simple app in SwiftUI, when I use  @Binding var show : Bool for second register screen, it is throw an error for this line of code   init(state: AppState) {             self.viewModel = RegisterViewModel(authAPI: AuthService(), state: state)           } as a "Return from initializer without initializing all stored properties" any idea? first screen: import SwiftUI struct RegisterFirstScreen: View {   @Binding var show : Bool   init(state: AppState) {             self.viewModel = RegisterViewModel(authAPI: AuthService(), state: state)     }   var body: some View {    NavigationLink(destination: RegisterSecondScreen(state: viewModel.state, show: $show),                            isActive: self.$pushActive) {                 Button {                              viewModel.signUp()                                     } label: {                   Text("Register Now")                     .padding()                    }               } } second screen: struct RegisterSecondScreen: View {   @ObservedObject var state: AppState       @Binding var show : Bool   var body: some View { Text("Next main screen") }}
