I like how the TabView control looks on the mac and ipad and decided to see if my current code can show the tabs in my multi-platform app just to realize that whenever I click on one of those tabs my macOS app currently crashes every time I press any other tab with the error: Thread 1: "NSToolbar 0x600003de33c0 already contains an item with the identifier com.apple.SwiftUI.navigationSplitView.toggleSidebar. Duplicate items of this type are not allowed." While trying to troubleshoot I noticed several other people have had a similar issue with differing reasons (toolbars and searchers mentioned) all in macOS since upgrading to 15.0: https://forums.developer.apple.com/forums/thread/763829 Minimal Viable Project: to show the issue I commented out most of my code calls hoping to create a project that worked so I could bring my code back in and see if it broke. I still had this issue so I next created a minimal viable example. Here it is: import SwiftUI import SwiftData @Model class Issue { var name: String init(name: String) { self.name = name } } @main struct TestMultiplatformApp: App { var sharedModelContainer: ModelContainer = { let schema = Schema([ Issue.self, ]) let modelConfiguration = ModelConfiguration(schema: schema, isStoredInMemoryOnly: false) do { return try ModelContainer(for: schema, configurations: [modelConfiguration]) } catch { fatalError("Could not create ModelContainer: \(error)") } }() var body: some Scene { WindowGroup { ContentView() } .modelContainer(sharedModelContainer) } } struct ContentView: View { @State var isCompact: Bool = true var body: some View { VStack { if isCompact { EntryTab() } else { EntrySidebar() } Toggle(isOn: $isCompact, label: { Text(isCompact ? "TabView" : "Sidebar") }) .padding(.horizontal, 20) .padding(.bottom, 20) } } } public struct tabControl: Identifiable, Hashable, Sendable { public static func == (lhs: tabControl, rhs: tabControl) -> Bool { lhs.id < rhs.id } public var id: Int // Tab Number public var displayName: String public init(id: Int, displayName: String) { self.id = id self.displayName = displayName } } struct EntryTab: View { let entryTabs = [ tabControl(id: 0, displayName: "row 0"), tabControl(id: 1, displayName: "row 1"), tabControl(id: 2, displayName: "row 2"), tabControl(id: 3, displayName: "row 3") ] @State private var selectedTab: Int = 0 var body: some View { TabView(selection: $selectedTab) { ForEach(entryTabs) { tabCtrl in NavigationSplitView { Text("Selected tab is \(selectedTab)") } detail: { Text("Choose item from sidebar... in future this would be content") } .tabItem { Text(tabCtrl.displayName) } .tag(tabCtrl.id) } } } } struct EntrySidebar: View { @State private var selectedTabID: Int? let entryTabs = [ tabControl(id: 0, displayName: "row 0"), tabControl(id: 1, displayName: "row 1"), tabControl(id: 2, displayName: "row 2"), tabControl(id: 3, displayName: "row 3") ] var body: some View { NavigationSplitView(sidebar: { List(entryTabs, id:\.id, selection: $selectedTabID) { thisItem in Text(thisItem.displayName) } }, content: { Text("Hi selected tab: \(String(describing: selectedTabID))") }, detail: { Text("Choose item from sidebar... in future this would be content") }) .onAppear() { // Set the selected tab selectedTabID = 1 } } }

I have a bug I've come across since I've upgraded Xcode (16.0) and macOS (15.0 Sequoia) and figured I'd create a minimal viable example in case someone else came across this and help. I've noticed this in both the macOS and iOS version of my app when I run it. Essentially I have an area of my code that calls a class that has a step 1 and 2 process. The first step uses async let _ = await methodCall(...) to create some SwiftData items while the second step uses a TaskGroup to go through the created elements, checks if an image is needed, and syncs it. Before this worked great as the first part finished and saved before the second part happened. Now it doesn't see the save and thus doesn't see the insertions/edits/etc in the first part so the second part just isn't done properly. Those step one changes are set and shown in the UI so, in this case, if I run it again the second part works just fine on those previous items while any newly created items are skipped. I came across this issue when step one handled 74 inserts as each one didn't contain an image attached to it. When I switched the async let _ = await methodCall(...) to a TaskGroup, hoping that would wait better and work properly, I had the same issue but now only 10 to 30 items were created from the first step. Minimal Viable Example: to reproduce something similar In my minimal viable sample I simplified it way down so you can't run it twice and it's limited it creating 15 subitems. That said, I've hooked it up with both an async let _ = await methodCall(...) dubbed AL and a TaskGroup dubbed TG. With both types my second process (incrementing the number associated with the subissue/subitem) isn't run as it doesn't see the subitem as having been created and, when run with TaskGroup, only 12 to 15 items are created rather that the always 15 of async let. Code shared here: https://gist.github.com/SimplyKyra/aeee2d43689d907d7a66805ce4bbf072 And this gives a macOS view of showing each time the button is pressed the sub issues created never increment to 1 while, when using TaskGroup, 15 isn't guaranteed to be created and remembered. I'm essentially wondering if anyone else has this issue and if so have you figured out how to solve it? Thanks

Hi, I'm updating my app from CoreData to SwiftData and came across an issue. My app has multiple users so in CoreData and I assigned each a myID value set to an UUID so I could use UserDefaults to set the preferred user on app load. When switching over I noticed the PersistentIdentifier value and got excited as I could fetch the matching entity with modelContext.model(for: yourID). I decided to use that instead so I updated my UserDefaults code from UUID to this: @Published var selectedUserID: PersistentIdentifier? { didSet { UserDefaults.standard.set(selectedUserID, forKey: "selectedUserID") } } init() { self.selectedUserID = UserDefaults.standard.object(forKey: "selectedUserID") as? PersistentIdentifier ?? nil } This code compiles and, of course the id is currently set to nil. My issue now is when I try to assign a user to it ar my app crashes and I get the following error: Attempt to set a non-property-list object SwiftData.PersistentIdentifier(id: SwiftData.PersistentIdentifier.ID(url: x-coredata://6FE80FC9-0B4C-491E-8093-DED37A619F1B/EnteredUser/p834), implementation: SwiftData.PersistentIdentifierImplementation) as an NSUserDefaults/CFPreferences value for key selectedUserID Should I go back to an additional UUID field in my user model and find it that way or is there a way to use the PersistentIdentifier value with my UserDefaults? Thanks for any tips.

I'm currently hooking up StoreKit2 to my app. I worked my way through an older example that listened to products and added/removed ids as they came up. This example fell short using the StoreKit config file as all subscriptions don't have a revocation date set so my list of purchased ids just grew longer (as they weren't removed). My app is only using a single subscription group and thus will only have one subscription live at once. I'm currently grabbing the current subscription using for await result in Transaction.currentEntitlements and am showing the subscriptions with StoreView(ids: arrayIds) and SubscriptionStoreView(groupID: subscriptionGroupID) depending where they user is. Currently when those views disappear I grab the current subscription again (thus updating it if it was changed). That seems cumbersome especially if it doesn't need to be updated and I'm not getting the following error: Making a purchase without listening for transaction updates risks missing successful purchases. Create a Task to iterate Transaction.updates at launch.. I'm wondering if there's a way to just listen to the StoreKit Subscription ID in my main App entry point thus making the final error disappear and maybe, if I could update the type of subscription, removing my onDisappear subscription fetches throughout the rest of the app. All the examples I come across seem to be either tied up with SwiftData (WWDC 2023) or older and maybe not applicable anymore. Everything seems to be embedded in StoreKit and it would be lovely if I could listen in one simple spot for in app and outside app subscription changes. Thanks :)

Hi, I'm looking through the Backyard Birds app and trying to wrap my head around StoreKit 2 and make it work with my app. Currently my app is three tabs that, for example, call access1, access2, and profile. I want to make users pay for access to the first two tabs and, by default, profile is visible on download for unsubscribed members. In the Backyard Birds app they have three levels that are clear cut and then they figure out access for family sharing by the highest level the user has. I currently have six subscriptions listed under my group: level1: all access annual all access monthly level2: access1 only annual access1 only monthly access2 only annual access2 only monthly My thought with this (not set up yet) is if the user subscribes to all access they have access to all three tabs. If they subscribe to access1 only they have access to the first and third(profile) tabs. If they subscribe to access2 then they have access to the second and third tabs. I guess my main problem is I don't know how to implement func status(for statuses: [Product.SubscriptionInfo.Status], ids: PassIdentifiers) -> PassStatus as if there's a family member with access1 and another family member with access2 then the current person should essentially have all access (all three tab access). Before I stumbled along further I wanted to check with all of you and see if there's a better way to set up or continue with the Backyard Pass example with different logic in status. Thanks everyone.

I'm setting up tests for my Xcode Multiplatform App. To create a test environment I created a docker image that I want to run an XCTestCase against. I understand I'd have to make sure Docker is running before running the test. That said I have a permission denied when trying to connect to the docker daemon socket. Background: I'm using a makefile to store the commands and planned to run the docker build and docker run commands in the setUpWithError while running the docker kill command in tearDownWithError. To run the commands I used Process to execute the shell commands. I'm currently doing this is a test function to get it up and going. Issue: When I try to run the docker command Xcode tells me that it doesn't give me the permission to run it: docker: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/create?name=remarkable": dial unix /var/run/docker.sock: connect: operation not permitted. See 'docker run --help'. I only want to use Docker to run this specific XCTestCase. Is there anyway to run it from here JUST for the test? Or do I need to manually run docker and kill it before/after I run these tests? Thanks for any help.

I'm looking to test my Xcode project using the default file set up XCTestCase... but I need to test it against a service that will need to be started before the test and stopped after the test. I was hoping to start and end it within the setUpWithError and tearDownWithError methods but I don't know how. Is there a way I could run commands from the testing environment? Basically I want to figure out where it's executing from ls one time, move my files over, and then I can go through starting the service setUpWithError, running the tests, and then ending the service tearDownWithError. Specifically the service runs a Docker image and I use a Makefile to make it a simple command. I just want to start and end it from the test environment. Thanks

I'm developing a Multiplatform app that uses CloudKit to sync the CoreData between the user's devices. At this time they don't share data between users. I have a single password field on a single Entity and was wondering if there was a simple way to encrypt just this field. I see in CoreData there's a checkbox labelled "Allows Cloud Encryption"... does checking that off magically encrypt it. I checked it off and nothing seemed to change so I unchecked it for now... is there something else I needed to do? And, most importantly, will it work with CloudKit?

Hi. I’m developing a multiplatform app for both iOS and macOS and was wondering if there’s any way to display an SVG file in the swiftUI view. I’ve seen ways online once you put the image in the assets file but this will be dynamic coming from outside the program. I just want to display and maybe rotate it but nothing more complicated than that. thanks

I'm attempting to figure out how to display a message to my users when some asynchronous code takes some time to run. So far I've used a sample I found online to create a popup banner and tied the message together using an ObservedObject of the async method on my view and Publishing the values. My sample code project is on a public GitHub repository here. https://github.com/SimplyKyra/CodeAttempts Right now I have an issue as when I set the variables in the async method I'm getting the following error: Publishing changes from background threads is not allowed; make sure to publish values from the main thread (via operators like receive(on:)) on model updates. Solutions online seem to fix this issue by updating the value on the @mainActor thread but I want these methods to run asynchronously AND update the user on what's happening. What's the best way to update my variables from this location?

Hey, During a developer Q&A today I was referred to a "Sundae shop" (the ice cream) sample code from, I think it was, WWDC 2020. Does anyone know where I can find it? I want it mainly for ObservedObject updates for my view from an async model. Thanks :)

I have a multiplatform app that I'm coding that uses HealthKit. To get it working I needed to add a custom entitlement to the entitlements file. Specifically "application-identifier". See this solved question for more information: https://developer.apple.com/forums/thread/713829 Now I can only run the app on my simulators and NOT on my phone or Mac as the automatic signing is failing Provisioning profile "iOS Team Provisioning Profile: myName.AppName" doesn't match the entitlements file's value for the application-identifier entitlement. It says to submit a bug report: Automatic signing failed. Xcode failed to provision this target. Please file a bug report at <https://feedbackassistant.apple.com> and include the Update Signing report from the Report navigator. Which I did FB11512832, but is there something I can do to fix this or is it just a wait and see? Error image:

Hey, I'm coding my app in the Xcode Beta 2 and am attempting to access the HKHealthStore() to add a HKCategorySample. When I run the app and attempt to add the sample I get the following error: Error Domain=com.apple.healthkit Code=4 "Missing com.apple.developer.healthkit entitlement." UserInfo={NSLocalizedDescription=Missing com.apple.developer.healthkit entitlement.} When I make sure to requestAuthorization before running the code I get a different error: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'NSHealthShareUsageDescription must be set in the app's Info.plist in order to request read authorization for the following types: HKCategoryTypeIdentifierMindfulSession' I'm assuming I need to add to my Info.plist but am unable to figure out how. If I go to my project or project's target and access Build Settings I see the following image: But am unable to edit it. I assuming I want to add NSHealthShareUsageDescription with a String explanation for why I want access but anything I find online is for an older Xcode so I don't know how to do it. Any help to get this working would be really appreciated. Thank you

Yesterday I had issues with my CoreData database for my Multiplatform app which resulted in changes to the schema. I reset the CloudKit version and, on the iOS simulator, had to delete my app and run the code again to get it to work. My issue is with the macOS target. I'm getting the same fatalError (Fatal error: Unresolved error Error Domain=NSCocoaErrorDomain Code=134140 "Persistent store migration failed, missing mapping model.") when running the macOS app but I can't figure out how to delete it so I can run it fresh like I did with the iOS version. I've found where the application is created (in the Debug directory ultimately within my app's Build directory) and removed them all but when run the newly created application has the same error. Should I move up the directory structure and remove the entire app directory within Xcode/DerivedData or is there another way? Wanted an answer before I do something I can't go back from :) Thanks, Kyra
