Hello everyone My goal is to create Apple's activity ring sparkle effect. So I found Paul Hudson's Vortex library. There is already a sparkle effect, but I don't know how to modify it to achieve my goal. Because I'm pretty new to SwiftUI animations. Does anyone have any idea how I could do this?

Hello everyone, I looked at various methods how to Unit/UITest SwiftData but I couldn't find something simple. Is it even possible to test SwiftData? Does someone found a solution for that?

My goal is to create Apples activity ring sparkle effect. So I found Paul Hudson's Vortex library. There is already a spark effect, but I don't know how to create a custom one that fits my needs. I'm still quite new to SwiftUI animations. Does someone have an idea how to do it? VortexView(createSparkle()) { Circle() .fill(.white) .frame(width: 16) .tag("circle") } func createSparkle() -> VortexSystem { let system = VortexSystem(tags: ["circle"]) system.birthRate = 150 system.emissionDuration = 0.2 system.idleDuration = 0.5 system.lifespan = 1.5 system.speed = 1.5 system.speedVariation = 0.2 system.angle = .degrees(330) system.angleRange = .degrees(30) system.acceleration = [0, 3] system.dampingFactor = 4 system.colors = .ramp(.white, .yellow, .yellow.opacity(0)) system.size = 0.1 system.sizeVariation = 0.1 system.stretchFactor = 8 return system } Vortex project: https://github.com/twostraws/Vortex

Hello everyone, How do I need to handle the delete with the relationship deny? When I delete a model that still has a reference to another model, it deletes it from the UI. But when I re-run the simulator, it's back again. Does someone have a hint for me? How is it possible to ensure the uniqueness of the entries? Because I saw that the Attribute unique can't be used with CloudKit.

Hello everyone I tried to upload my playground app via Xcode to AppStore Connect. Unfortunately it didn’t worked. I tried everything what the error suggested me to do. But its still not working. Has anyone ever encountered this error?

I started playing around with the navigationDestination modifier. But currently it always re-routes me back to the list with the entries. Does someone have an idea why this happens? MainView NavigationStack { Form { Section { ProgressRing(percentage: $percentage) Text("1 of 3 compleatet") .font(.title2) .fontWeight(.medium) .foregroundStyle(Color.accentColor) } .listRowBackground(Color.clear) .listRowSeparator(.hidden) .frame(maxWidth: .infinity ,alignment: .center) .padding() Section("Daily tasks") { NavigationLink { EmptyView() } label: { Label("Log mood", systemImage: "seal") } NavigationLink { QuoteView() } label: { Label("Quote Gallery", systemImage: "seal") } NavigationLink { GratitudeListView() } label: { Label("Writing down gratitude", systemImage: "seal") } } } .navigationTitle("Hello, \(users.first?.name ?? "User")") } List { ForEach(gratitudes, id: \.self) { gratitude in NavigationLink(value: gratitude) { VStack(alignment: .leading) { Text(gratitude.gratitude1) Text(gratitude.createdAt, style: .date) } } } .navigationDestination(for: Gratitude.self, destination: { gratitude in GratitudeUpdateView(gratitude: gratitude) }) } .navigationTitle("Gratitude") .toolbar(.hidden, for: .tabBar) .overlay(alignment: .bottom) { NavigationLink { GratitudeAddView() } label: { PlusButton() } }

Hello everyone, Is there a way to set the minimum deployment target in Xcode Playground?

Hello everyone, Is there a better solution than my approach out there to convert an image to data and back? @Model class User { var name: String @Attribute(.externalStorage) var image: Data? var createdAt: Date init(name: String, image: Data, createdAt: Date = .now) { self.name = name self.image = image self.createdAt = createdAt } } if let selectedPhotoData = imageData, let uiImage = UIImage(data: selectedPhotoData) { Image(uiImage: uiImage) .resizable() .scaledToFill() .frame(width: 300, height: 300, alignment: .center) .clipShape(Circle()) } .task(id: selectedPhoto) { if let data = try? await selectedPhoto?.loadTransferable(type: Data.self) { imageData = data } }
