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? Thanks in advance MapView import MapKit import SwiftUI struct City: Identifiable {     let id = UUID()     let name: String     let coordinate: CLLocationCoordinate2D } struct MapView: View {     @State private var region = MKCoordinateRegion(center: CLLocationCoordinate2D(latitude: 46.62407, longitude: 8.03434), span: MKCoordinateSpan(latitudeDelta: 0.1, longitudeDelta: 0.1))          let annotations = [         City(name: "Alte Strasse(Zuhause)", coordinate: CLLocationCoordinate2D(latitude: 46.63649, longitude: 7.97512)),         City(name: "Stalden1", coordinate: CLLocationCoordinate2D(latitude: 46.63937, longitude: 7.97216)),         City(name: "Stalden2", coordinate: CLLocationCoordinate2D(latitude: 46.63873, longitude: 7.96684)),         City(name: "Scheideggstrasse(Wetterhorn)1", coordinate: CLLocationCoordinate2D(latitude: 46.63353, longitude: 8.07356)),         City(name: "Scheideggstrasse(Wetterhorn)2", coordinate: CLLocationCoordinate2D(latitude: 46.63293, longitude: 8.07380)),         City(name: "Scheideggstrasse(Wetterhorn)3", coordinate: CLLocationCoordinate2D(latitude: 46.63313, longitude: 8.07329)),         City(name: "Scheideggstrasse(Wetterhorn)4", coordinate: CLLocationCoordinate2D(latitude: 46.63456, longitude: 8.07337)),         City(name: "Obere Gletscherstrasse(Wetterhorn)", coordinate: CLLocationCoordinate2D(latitude: 46.63205, longitude: 8.07022)),         City(name: "Obere Gletscherstrasse(Hotel Blümlisalp)", coordinate: CLLocationCoordinate2D(latitude: 46.63173, longitude: 8.06699)),         City(name: "Itramenstrasse", coordinate: CLLocationCoordinate2D(latitude: 46.62060, longitude: 7.99514))     ]     var body: some View {         Map(coordinateRegion: $region, annotationItems: annotations) {             MapMarker(coordinate: $0.coordinate)             }         .onAppear {             MKMapView.appearance().mapType = .satellite         }             }     struct MapView_Previews: PreviewProvider {         static var previews: some View {             MapView()         }     } } PhotoView 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(.fixed(180), spacing: 16), GridItem(.fixed(180), spacing: 16)]              var body: some View {         NavigationView {             ScrollView {                 LazyVGrid(columns: columnGrid, alignment: .center, spacing: 16) {                     ForEach(images, id: \.self) { image in                         NavigationLink (destination: ImageDetail(imageName: image)) {                             Image(image)                                 .resizable()                                 .scaledToFit()                                 .cornerRadius(10)                         }                     }                 }             }.navigationBarTitle(Text("Test"), displayMode: .inline)         }.navigationViewStyle(.stack)     } }

Recently I've been working on a demo project called iLibrary. The main goal was to learn more about CloudKit and SwiftData. After a while I noticed that there were some hangs/freezes when running the app in debug mode. I first tried this with Xcode 15.4 and iOS 17.5. Here the hang only appears at the beginning, but only for a few seconds. But when I exit debug mode, there are no more hangs. With Xcode 16 beta 4 and iOS 18 it looks completely different. In this case, the hangs and freezes are always present, whether in debug mode or not. And it's not just at the beginning, it's throughout the app. I'm aware that this is still a beta, but I still find this weird. And when I profile this I see that the main thread gets quite overloaded. Interestingly, my app doesn't have that many operations going on. So I guess something with the sync of SwiftData or my CloudKitManger where I fetch some records from the public database is not running fine. Lastly, I wanted to delete the iCloud app data. So I went to Settings and tried to delete it, but it didn't work. Is this normal? Does anyone have any idea what this could be? Or has anyone encountered this problem as well? I'd appreciate any support. My project: https://github.com/romanindermuehle/iLibrary

Hey there, does someone know why the ContentUnavailableView is behaving differently on iOS 26 than in iOS 18 but the code is the same?

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?

Lately, I keep getting this warning when closing Xcode asking if I want to save the changes. Strangely enough, I have never received this before. I looked to see if I could disable and enable autosave. Unfortunately I have not found anything. Does anyone have any tips?

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?

Hey there, I’m currently exploring the possibility of integrating Sign in with Apple into my iOS app and backend. Regarding the iOS app, I’ve read that when a user is signed in, you always need to call getCredentialState on the app’s launch. Is this true? If so, how is it possible to sign the user out then? I intend to incorporate SwiftData and CloudKit into my application. In light of this, I’m curious about your approach to user management. Specifically, I’m wondering if you would store the user’s data in a Redis database after successful authentication on the backend. Or, would you separate the user data and save it using SwiftData/ CloudKit?

Good day, I have the problem that when I switch from one view to another, the content is moved to the bottom every time. I have already tried with the: See picture attached: [https://we.tl/t-SUYZZh6M2P) Does anyone have a solution suggestion? Greetings

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 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 } }

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?

Recently I noticed that when I build and archive my app with Xcode Cloud, it fails due to code signing issue. But that's weird because I have all development and distribution certificates. Does anyone have any idea how to solve this?

Helle there Currently, I’m attempting to create an interactive learning application with a 3D view. I’ve discovered the framework SceneKit, but I lack the necessary knowledge to animate, load and moving objects. Could someone kindly suggest some good articles or tutorials on this topic?
