Hello, how can I add a detail view to this code? I want to show the image in a detail view and that for every image single. import SwiftUI struct ContentView: View {     var images: [String] = ["noaa1", "noaa2", "noaa3", "noaa4", "noaa5", "noaa6", "noaa7", "noaa8", "noaa9", "noaa10", "noaa11", "noaa12", "noaa13", "noaa14", "noaa15", "noaa16", "noaa17", "noaa18"]          var columnGrid: [GridItem] = [GridItem(.flexible()), GridItem(.flexible())]          var body: some View {             ScrollView {                 LazyVGrid(columns: columnGrid) {                     ForEach(images, id: \.self) { image in                         Image(image)                             .resizable()                             .scaledToFit()                             .cornerRadius(10)                                      }             }         }     }          struct ContentView_Previews: PreviewProvider {         static var previews: some View {             ContentView()         }     } }

Hello, I struggling to integrate this code below in my Content View can someone give me help? import UIKit import QuickLook import ARKit class ViewController: UIViewController, QLPreviewControllerDataSource {     override func viewDidAppear(_ animated: Bool) {         let previewController = QLPreviewController()         previewController.dataSource = self         present(previewController, animated: true, completion: nil)     }     func numberOfPreviewItems(in controller: QLPreviewController) -> Int { return 1 }     func previewController(_ controller: QLPreviewController, previewItemAt index: Int) -> QLPreviewItem {         guard let path = Bundle.main.path(forResource: "myScene", ofType: "reality") else { fatalError("Couldn't find the supported input file.") }         let url = URL(fileURLWithPath: path)         return url as QLPreviewItem     } }

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?

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.

I am currently working on an app that utilizes SwiftData, and I am planning to integrate CloudKit. My current challenge involves managing a Day object that gets inserted when the date changes to track daily progress. Additionally, I want to prompt users to create a username during the app's onboarding process. I am concerned that this could lead to synchronization issues, such as duplicate entries for the same day or multiple user accounts being created. I assume blocking the app until everything is synced from CloudKit is not a practical solution. Does anyone have any recommendations on how to handle this? Furthermore, I would like to implement a community feature where users can post content. I noticed that CloudKit offers a public database. Is this database suitable for such a feature, or would I need to develop a separate backend to support it?

This week, I developed a small multiplatform RealityKit project. I also created a demo scene in Reality Composer Pro. Afterward, I imported the local package into the project. Running the project on macOS works perfectly. However, when I tried to run it on my iPhone, I encountered a permission error indicating that it couldn’t read the package. This seems unusual to me because I assumed that the dependency is bundled into the binary file. In an attempt to resolve the issue, I pushed the RCP package to GitHub, hoping it would work. Fortunately, everything compiles successfully now, but the loading time is significantly long, and the animations don’t play on tap gestures. Could someone please help me identify the root cause of this problem?

Currently, I’m working on developing a small macOS utility tool for my photography. In my camera, I have a digital zoom feature. I prefer using this feature when I shoot both JPEG and DNG files. While the JPEG is already cropped to the desired format, the DNG file contains metadata (DefaultUserCrop: 0.22, 0.22, 0.78, 0.78). For instance, when I open that DNG file in Lightroom, it pre-crops the image non-destructively. However, I prefer using Pixelmator Pro for editing. Unfortunately, Pixelmator Pro doesn’t have this feature. So, I thought I could create an app that allows me to pre-crop the image for editing in Pixelmator Pro afterward. Does someone have a better idea or some hints on how I could solve it?

I will briefly explain my view. My goal is to make a list where you can enter all personal information like a kind of emergency passport. There should also be text fields where you can tap on the plus button and then there is a new text field. On the top right I want to make an edit button that you can delete text fields again. I will connect this view with another SwiftUI view file. Does anyone have an idea how to solve this problem with the list? import SwiftUI struct ListeDaten: Identifiable { let id = UUID() let Name: String let Adresse: String var Telefonnummern: [String] = [] var Something: String = "" } struct ListeDaten: View {     var body: some View {                  TextField(Name: "Name/Vorname")         TextField(Adresse: "Adresse")         ForEach(id: \.self) {Telefonnummern in TextField("Telefonnummer")}         Button(action: {             Telefonnummern.append("")         })         {             Image(systemName: "plus.circle.fill")                 .foregroundColor(Color(.systemGreen))         }     } } struct ListeDaten_Previews: PreviewProvider {     static var previews: some View {         ListeDaten()     } }

Hello, I want to implement AR quick look to my app. I' don't want to use UIKit but SwiftUI. In one of my views, I want to press a button named "preview" and then it should open the AR quick look. Have someone an idea how I can do that? Sorry for that badly formatted code below. import UIKit import QuickLook import ARKit class ViewController: UIViewController, QLPreviewControllerDataSource { override func viewDidAppear(_ animated: Bool) { let previewController = QLPreviewController() previewController.dataSource = self present(previewController, animated: true, completion: nil) } func numberOfPreviewItems(in controller: QLPreviewController) -> Int { return 1 } func previewController(_ controller: QLPreviewController, previewItemAt index: Int) -> QLPreviewItem { guard let path = Bundle.main.path(forResource: "myScene", ofType: "reality") else { fatalError("Couldn't find the supported input file.") } let url = URL(fileURLWithPath: path) return url as QLPreviewItem } } [https://developer.apple.com/documentation/arkit/previewing_a_model_with_ar_quick_look)

Hello everyone, how can I change the standard pin icon to another? And how is it possible when I tap on the pin that an additional popup view opens in which the name of the city is at the top and that the associated image from the PhotoView is displayed? How could I best implement this?

Hi everyone At the moment I try to use augmented reality QuickLook in Swift playgrounds When I try to open the reality file from the resource folder, this error shows up. Have someone an idea to fix that problem? Thanks in advance import QuickLook import RealityKit import ARKit struct ARQLViewController: UIViewControllerRepresentable {     func makeUIViewController(context: Context) -> some UIViewController {         return UINavigationController.init(rootViewController: ViewController())     }     func updateUIViewController(_ uiViewController: UIViewControllerType, context: Context) {} } class ViewController: UIViewController, QLPreviewControllerDataSource {     var isAppeard: Bool = false     override func viewDidLoad() {         super.viewDidLoad()         DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) {             let previewController = QLPreviewController()             previewController.dataSource = self             self.present(previewController, animated: true, completion: nil)         }     }    override func viewDidAppear(_ animated: Bool) {         guard !isAppeard else { return }         isAppeard = true         }     func numberOfPreviewItems(in controller: QLPreviewController) -> Int { return 1 }     func previewController(_ controller: QLPreviewController, previewItemAt index: Int) -> QLPreviewItem {         guard let path = Bundle.main.path(forResource: "SipARAnimation", ofType: "reality") else { fatalError("Couldn't find the supported input file.") }         let url = URL(fileURLWithPath: path)         return url as QLPreviewItem     } }

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() } }

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, 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?

When I parse the query result(SwiftData) to my DetailView it works fine. But when I delete the item in the DetailView the view isn't updated. I parse the array from the dataModel to the DetailView. But I do not understand why it's not updating when I add or delete a tree in the DetailView. Only when I append the tree to the array from the other model after insert it works. Does someone have a tip for me? Here is my Code: https://gist.github.com/romanindermuehle/14441c21f689e91b26942d997f75300d
