Hello I implemented the filter function in my ForEach loop, and it works just with the valori property but not with the date property , is there a way to let it filter also the date? I tried to remove the dateFormatter but it didn't work. Here is the code import SwiftUI let dateFormatter: DateFormatter = { let formatter = DateFormatter() formatter.dateStyle = .medium return formatter }() struct Test4: View { @State private var text: String = "" var body: some View { NavigationView{ if !lifetimes.isEmpty{ List{ Section(header: Text("")){ TextField("Search", text: $text) } Section(header: Text("")){ ForEach(lifetimes.filter { text.isEmpty || "\($0)".contains(text) }, id: \.id){ lifetimeInputs in HStack{ Text("\(lifetimeInputs.valori, specifier: "%.0f")") Spacer() Text("\(dateFormatter.string(from: lifetimeInputs.date))") } } } } .listStyle(InsetGroupedListStyle()) .navigationTitle("All History") } else{ VStack{ Text("No Data") .font(.largeTitle) .fontWeight(.semibold) .foregroundColor(.secondary) } .padding(.bottom) .navigationTitle("All History") } } } } struct LifetimeInputsModel: Identifiable { var id = UUID() var valori: Double var date: Date } var lifetimes: [LifetimeInputsModel] = [ LifetimeInputsModel(valori: 300, date: Date()), LifetimeInputsModel(valori: 200, date: Date() + 86400) ] Thank you

Hello Does anyone know how to use real time image recognition in SwiftUI with a Create ML model. Thank you

Hello I am trying to save some data in the Health App from my app, and it is working, the problem is that when I delete that data (already saved) from my app (using the deleteFromHealthKit function) the data is not deleted from the health app. How can I fix this? Here is the code: import SwiftUI import HealthKit struct ContentView: View { init() { //-------- let healthStore = HKHealthStore() let allTypes = Set([HKObjectType.quantityType(forIdentifier: .dietaryWater)!]) healthStore.requestAuthorization(toShare: allTypes, read: allTypes) { (success, error) in if !success { print("success") } } } func fetchHealthData(date: Date, ml: Double) -> Void { let healthStore = HKHealthStore() let quantityType = HKObjectType.quantityType(forIdentifier: HKQuantityTypeIdentifier.dietaryWater) let waterConsumed = HKQuantitySample.init(type: quantityType!, quantity: .init(unit: HKUnit.literUnit(with: .milli), doubleValue: ml), start: date, end: date) healthStore.save(waterConsumed) { success, error in if (error != nil) { print("Error: \(String(describing: error))") } if success { print("Saved: \(success)") } } } @State var water: [Water] = [] @State private var value: Double = 0 func deleteFromHealthKit(date: Date, ml: Double) { let healthStore = HKHealthStore() let quantityType = HKObjectType.quantityType(forIdentifier: HKQuantityTypeIdentifier.dietaryWater) let waterConsumed = HKQuantitySample.init(type: quantityType!, quantity: .init(unit: HKUnit.literUnit(with: .milli), doubleValue: ml), start: date, end: date) healthStore.delete(waterConsumed) { success, error in if (error != nil) { print("Error: \(String(describing: error))") } if success { print("Saved: \(success)") } } } var body: some View { NavigationView{ VStack{ Text("Value: \(value)") .padding() HStack{ Text("100 ml") .onTapGesture { value = 100 } Text("200 ml") .onTapGesture { value = 200 } } Button("Add"){ water.append(Water(value: value, date: Date())) fetchHealthData(date: Date(), ml: value) }.disabled(value == 0 ? true : false) .padding() List{ ForEach(0..<water.count, id: \.self){ i in HStack{ Text("\(water[i].value)") Text("\(water[i].date)") } .onTapGesture { deleteFromHealthKit(date: water[i].date, ml: water[i].value) water.remove(at: i) } } } } } } } struct Water: Identifiable { var id = UUID() var value: Double var date: Date } Thank you

Hello Is there a way to sync notifications that are created locally, on CloudKit, I am using this function to create notifications and I am saving everything in an array func scheduleNotifications(date: Date, identfier: String) { UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound]) { success, error in if success { print("Success") } else if let error = error { print(error.localizedDescription) } } let content = UNMutableNotificationContent() content.title = "Notification" content.body = "Notification." content.sound = UNNotificationSound.default var dateComponents = DateComponents() dateComponents.hour = Int(hourFormatter.string(from: date)) ?? 0 print(hourFormatter.string(from: date)) dateComponents.minute = Int(minuteFormatter.string(from: date)) ?? 0 print(minuteFormatter.string(from: date)) let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: true) let request = UNNotificationRequest(identifier: identfier, content: content, trigger: trigger) UNUserNotificationCenter.current().add(request) } Thank you

Hello I am developing an app with SwiftUI using CoreData and iCloudKit to sync data between platforms. The problem is that the iCloud background update is not being triggered when staying in the application. If I make changes on both systems, the changes are being pushed, however not visible on the other device. I need to reload the app, close the app and open again. I already enabled iCloud capability, background notifications and push notifications. This is my persistentContainer var persistentContainer: NSPersistentCloudKitContainer = { let container = NSPersistentCloudKitContainer(name: "Test7") container.loadPersistentStores(completionHandler: {(StoreDescription, error) in if let error = error as NSError? { fatalError("Unresolved error \(error), \(error.userInfo)") } }) container.viewContext.automaticallyMergesChangesFromParent = true container.viewContext.mergePolicy = NSMergeByPropertyStoreTrumpMergePolicy return container }() func saveContext() { let context = persistentContainer.viewContext if context.hasChanges{ do { try context.save() } catch { let nserror = error as NSError fatalError("Unresolved error \(nserror), \(nserror.userInfo)") } } } This is my model class ItemsModel: ObservableObject { init() { readData() } @Published var dataInputs: [Item] = [] let context = persistentContainer.viewContext func readData(){ let request: NSFetchRequest<Item> = Item.fetchRequest() do { let results = try context.fetch(request) self.dataInputs = results } catch { print(error.localizedDescription) } } func addItem(todo: String, date: Date){ let entity = NSEntityDescription.insertNewObject(forEntityName: "Item", into: context) as! Item entity.todo = todo entity.date = date do { try context.save() self.dataInputs.append(entity) } catch { print(error.localizedDescription) } } func deleteItems(indexSet: IndexSet){ for index in indexSet{ do { let obj = dataInputs[index] context.delete(obj) try context.save() let index = dataInputs.firstIndex(of: obj) dataInputs.remove(at: index!) } catch { print(error.localizedDescription) } } } } and this is my view struct ContentView: View { @EnvironmentObject var items: ItemsModel var body: some View { NavigationView{ List { ForEach(items.dataInputs) { item in Text("Item at \(item.date!)") } .onDelete(perform: items.deleteItems) } .toolbar { Button { items.addItem(todo: "Hello", date: Date()) } label: { Image(systemName: "plus") } } } } } Thank you

Hello Is there a way to share data stored in CloudKit and CoreData between iOS and watchOS in SwiftUI? I am using the same CoreData file both, and I am using the same PersistenceController file both, and I am using the same CloudKit container for both. I tried adding the App Groups capability to all the targets, but it is not working. (I already enabled iCloud capability, Push notification capability and background Modes capability for both iOS and WatchOS)  PersistenceController: struct PersistenceController { static let shared = PersistenceController() static var preview: PersistenceController = { let result = PersistenceController(inMemory: true) let viewContext = result.container.viewContext do { try viewContext.save() } catch { let nsError = error as NSError fatalError("Unresolved error \(nsError), \(nsError.userInfo)") } return result }() let container: NSPersistentCloudKitContainer init(inMemory: Bool = false) { container = NSPersistentCloudKitContainer(name: "Test7") if inMemory { container.persistentStoreDescriptions.first!.url = URL(fileURLWithPath: "/dev/null") } container.loadPersistentStores(completionHandler: { (storeDescription, error) in if let error = error as NSError? { fatalError("Unresolved error \(error), \(error.userInfo)") } }) container.viewContext.automaticallyMergesChangesFromParent = true container.viewContext.mergePolicy = NSMergeByPropertyStoreTrumpMergePolicy } } View: struct ContentView: View { @FetchRequest( entity: Item.entity(), sortDescriptors: [] ) var items: FetchedResults<Item> @Environment(\.managedObjectContext) private var context var body: some View { NavigationView{ List { ForEach(items) { item in Text("Item at \(item.date!)") } .onDelete(perform: deleteItems) } .toolbar { Button { addItem() } label: { Image(systemName: "plus") } } } } private func addItem() { withAnimation { let newItem = Item(context: context) newItem.date = Date() do { try context.save() } catch { let nsError = error as NSError fatalError("Unresolved error \(nsError), \(nsError.userInfo)") } } } private func deleteItems(offsets: IndexSet) { withAnimation { offsets.map { items[$0] }.forEach(context.delete) do { try context.save() } catch { let nsError = error as NSError fatalError("Unresolved error \(nsError), \(nsError.userInfo)") } } } } Thank you

Hello I am making a counter app using Core Data to store the value that the user has reached, the problem is that in the DetailView the value changes just if I close the view and reopen it, how can I change the value immediately when the user taps the button? ContentView: struct ContentView: View { @Environment(\.managedObjectContext) private var viewContext @FetchRequest( sortDescriptors: [NSSortDescriptor(keyPath: \Item.date, ascending: true)], animation: .default) private var items: FetchedResults<Item> @State private var isShown: Bool = false var body: some View { NavigationView{ List { Section(header: Text("All counters")){ ForEach(items) { item in NavigationLink( destination: DetailView(item: item) .environment(\.managedObjectContext, viewContext) , label: { HStack{ Text(item.name ??

Hello How can I set up local notifications that repeat every X minutes from a certain hour to another hour. For example, I want to receive a notification every 60 minutes starting from 12:00 AM to 10:00 PM? func scheduleNotifications() { let content = UNMutableNotificationContent() content.title = "App" content.subtitle = "App" content.sound = UNNotificationSound.default let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 60, repeats: true) let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: trigger) UNUserNotificationCenter.current().add(request) } With this code I can schedule a notification every minute, however, I cannot decide from what time it should start or when it stops. Any ideas? Thank you!

Hello I noticed that in my app, when I add data (I am using Core Data) the size of the app increases, as expected, the problem occurs when I delete data, the size of the app remains unchanged and sometimes increases, I thought there was an error in the my code and so I created, from scratch, a project for iOS with SwiftUI and Core Data enabled (the default template that Xcode provides) and also with the SwiftUI & Core Data default app the same problem happens. Is there a way to fix it or is there an explanation for this? Thank you!

Hello I am using matched Geometry Effect to make animations and transitions, the problem is that when I press to start the animation, the object being animated, in this case Text, is duplicated during the transition, and then when I press again to get it back to its original position, no animation takes place, how can I fix it. Here is the code: struct ContentView: View { @StateObject var numberViewModel = NumberViewModel() @Namespace var animation var body: some View { GeometryReader { geo in NavigationView{ ZStack { ScrollView{ LazyVGrid(columns: [GridItem(.flexible()), GridItem(.flexible())]) { ForEach(numbers){ number in NumberView(numberViewModel: numberViewModel, animation: animation, number: number) .onTapGesture { withAnimation(.easeInOut(duration: 1)){ numberViewModel.selected = number numberViewModel.tapped = true } } } } } if numberViewModel.tapped{ NumberTappedView(animation: animation, numberViewModel: numberViewModel) .position( x: geo.frame(in:.global).midX, y: geo.frame(in:.global).midY ) .onTapGesture { withAnimation(.easeInOut(duration: 1)){ numberViewModel.selected = Number(number: 0) numberViewModel.tapped = false } } } } } } } } struct NumberView: View { @ObservedObject var numberViewModel: NumberViewModel var animation: Namespace.ID var number: Number var body: some View{ GroupBox{ if !(numberViewModel.selected.number == number.number){ Text("\(number.number)") .font(.largeTitle) .frame(width: 100, height: 100, alignment: .center) .matchedGeometryEffect(id: number.number, in: animation) } } } } struct Number: Identifiable { var id = UUID() var number: Int } var numbers: [Number] = [ Number(number: 1), Number(number: 2) ] struct NumberTappedView: View { var animation: Namespace.ID @ObservedObject var numberViewModel: NumberViewModel var body: some View{ GroupBox{ Text("\(numberViewModel.selected.number)") .font(.largeTitle) .frame(width: 200, height: 200, alignment: .center) .matchedGeometryEffect(id: numberViewModel.selected.number, in: animation) } } } class NumberViewModel: ObservableObject { @Published var selected: Number = Number(number: 0) @Published var tapped: Bool = false } Thank You!

Hello I was trying to use @FetchRequest in a class, but found it doesn't work, so I was wondering if there was a way to use something that works like @FetchRequest in a class? Thank You!

Hello In my previous post I asked: https://developer.apple.com/forums/thread/689720 (Read my previous post before continuing, please) My question now is, if I compare Dates between each other will they be formatted or not, and how would I fix this? Thank You

Hello I wanted to know why when I print(Date()) the date is printed but two hours before? Example If I print(Date()) and the actual date is 2021-09-10 22:33:41 +0000, it prints 2021-09-10 20:33:41 +0000 instead of 2021-09-10 22:33:41 +0000. Why does this happen? Thank You!

Hello I created a custom shape in SwiftUI and I am trying to rotate it around a circle, but it works just on the top part of the circle, can you help me make it rotate exactly around the circle? (And also can I get the same effect using radians? How?) Here is the code: import SwiftUI struct MyGameView: View { @State private var degress: Double = 0 let timer = Timer.publish(every: 0.05, on: .main, in: .common).autoconnect() var body: some View { VStack{ ZStack{ Circle() .frame(width: 80) ZStack{ Circle() .stroke(lineWidth: 1) .frame(width: 300) BallonShape() .scaledToFit() .scaleEffect(0.2) .foregroundColor(.red) .rotationEffect(.degrees(degress), anchor: .bottom) .offset(x: 0, y: -170) } } } .onReceive(timer) { input in withAnimation(.easeIn(duration: 0.05).speed(10)){ degress += 1 } } } } struct BallonShape: Shape { func path(in rect: CGRect) -> Path { Path { path in path.move(to: CGPoint(x: rect.midX, y: (rect.maxY + rect.midY) / 2)) path.addCurve(to: CGPoint(x: rect.midX, y: rect.minY), control1: CGPoint(x: (rect.midX + rect.minX) / 2, y: rect.minY), control2: CGPoint(x: (rect.midX + rect.minX) / 2, y: rect.minY)) path.addCurve(to: CGPoint(x: rect.midX, y: (rect.maxY + rect.midY) / 2), control1: CGPoint(x: (rect.midX + rect.maxX) / 2, y: rect.minY), control2: CGPoint(x: (rect.midX + rect.maxX) / 2, y: rect.minY)) } } } Thank You very much!
