Since last night we've been seeing this error on every build: The Build - iOS action could not complete due to an error. Something went wrong and the Xcode Cloud team has been notified to investigate. The error may not occur on rebuild. Is there anything that we can do? Every build fails now. Thanks.

We've been running Xcode Cloud smoothly for the last few months, and everything's been great. Yesterday everything was fine, but builds triggered today, start failing. Since last night to today there's been no changes in the project, but we're getting this: Invalid Provisioning Profile. The provisioning profile included in the bundle fm.here.ios.dev [Payload/Here.app] is invalid. [Missing code-signing certificate]. A Distribution Provisioning profile should be used when submitting apps to the App Store. For more information, visit the iOS Developer Portal. Not sure why out of the blue the provisioning profile is missing the code-signing certificate. Everything's automatically managed by Xcode, so I'm not sure what has changed. We get it for our fm.here.ios.dev app and for the regular fm.here.ios one, so not isolated to a single one, seems to be happening to all of them. I can't see anything expired on the developer portal, has there been a deploy of Xcode Cloud / App Store Connect that could trigger this?

I have an app that uses NSPersistentCloudKitContainer to store all the data so it's backed by iCloud and synced between devices. Such app has a Share Extension, that can be triggered both from iOS (and iPadOS) and macOS (Catalyst). I was wondering if it's safe to instantiate an NSPersistentCloudKitContainer from a Share Extension due to it being very short lived. At the moment, I'm sending the data straight to iCloud instead of instantiating an NSPersistentCloudKitContainer, but it feels wrong because I'm using the keys that NSPersistentCloudKitContainer created internally (CD_MyEntity, CD_myProperty, etc.) to send it to iCloud and then being correctly pulled by my clients. The only concern that I have is that bringing up an NSPersistentCloudKitContainer that has to pull data, might delay or even loose the data that I'm saving right now because it gets killed after some amount of time since the share action has been completed. Any insights will be much appreciated, because if it's safe to use an NSPersistentCloudKitContainer from a Share Extension, I could remove a ton of fragile code! 🙏

I have an app that has a main target, a Share Extension and an App Extension. I save data from any of the extensions, but the UI is never updated on the main app when going back into it if the app was on the background (alive, not terminated). If the app was terminated, it all works as expected because it loads everything from scratch. If the app was on the background, it's not updated until a save from an unrelated part of the code occurs. It feels like @FetchRequest's is not aware of remote (meaning from other processes) changes, is this something that has to be done manually? I have both suggested options enabled: storeDescription.setOption(true as NSNumber, forKey: NSPersistentHistoryTrackingKey) storeDescription.setOption(true as NSNumber, forKey: NSPersistentStoreRemoteChangeNotificationPostOptionKey) When using UIKit with an NSFetchedResultsController, you could simply call performFetch to force the refresh of the controller when the app became active, but I don't see a way to force a refresh on a @FetchRequest.

If you have configured your workflows to use 'Latest Release', and there's a Release Candidate available, Xcode Cloud decides to use it. The problem is that the App Store rejects builds submitted with Release Candidate builds, at least that's what I'm encountering with Xcode 15.3 on the 27th of February, 2024: This is the error: Unsupported SDK or Xcode version. Your app was built with an SDK or version of Xcode that isn’t supported. Although you can use beta versions of SDKs and Xcode to build and upload apps to App Store Connect, you need to use the latest Release Candidates (RC) for SDKs and Xcode to submit the app. For details on currently supported SDKs and versions of Xcode, visit: https://developer.apple.com/news/releases. I'm not really sure if the issue is on Xcode Cloud or on the App Store, but something's up and they don't like each other right now!

I've just updated to Xcode 15.3 and iOS 17.4 (simulator). Every time I launch the app, I see a CPU spike keeping the CPU at 100% for about 30 seconds on a background thread. After those 30 seconds, there's a 'Thread Performance Checker' error posted on the console. This does not happen when using Xcode 15.2 and running on iOS 17.2. or iOS 16.4. Thread Performance Checker: Thread running at User-initiated quality-of-service class waiting on a thread without a QoS class specified (base priority 33).

I needed to verify something on the CloudKit console but it doesn't seem to be working even though the system status says that it's operational: http://developer.apple.com/system-status/ Is anyone experiencing the same issue? I can't load the databases, zones nor saved queries. For Apple folks, here's the feedback number: FB9756611

I'm observing a weird issue with SwiftUI Lists on macOS (they do work as expected on iOS). The problem is that the List calls the init & body of every row, even if those rows are not on screen (and might never be shown). If I replace the List with a ScrollView + LazyVStack, it does work as expected (only those rows which are going to be rendered get their init & body called). Of course, this is is not an ideal workaround because you loose the built-in benefits of using a List (mainly selection in my case). I did expect that under the hood, SwiftUI would use the same mechanism as NSTableView (which loads cells on demand). Historically I'm an iOS dev, so I'm used to cellForRowAtIndexPath coming from UITableView. Here's a quick gist demonstrating the issue: import SwiftUI @main struct SwiftUIListVSLazyVStackApp: App {     let numbers = (0...100).map { $0 }     var body: some Scene {         WindowGroup {             /*              List calls the init & the body of *every* element on the list, even if it's not being displayed.              This is unexpected because a tableView usually only loads the visible cells as needed (cellForRowAtIndexPath)              */             List(numbers) { number in                 RowView(for: number, example: "list")             }             /*              A combination of ScrollView + LazyVStack achieves what's expected from the list. Only calls the init & body of              the element that's going to be displayed.              */ //            ScrollView { //                LazyVStack(alignment: .leading, spacing: 8) { //                    ForEach(numbers) { number in //                        RowView(for: number, example: "stack") //                    } //                } //            }         }     } } struct RowView: View {     private let number: Int     private let example: String     init(for number: Int, example: String) {         print("Init \(example): \(number)")         self.number = number         self.example = example     }     var body: some View {         let _ = print("Body \(example): \(number)")         Text("\(number)")             .onAppear{ print("Appear \(example): \(number)") }     } } extension Int: Identifiable {     public var id: Int { self } } GitHub gist: https://gist.github.com/xmollv/7ecc97d8118c100e85698c5ff09a20dc And a video to better show the issue if you can't run the code: https://gist.github.com/xmollv/7ecc97d8118c100e85698c5ff09a20dc?permalink_comment_id=4140623#gistcomment-4140623 Twitter thread: https://twitter.com/xmollv/status/1517158777882955779 Any help is very much appreciated!

I'm being faced with an issue when using SwiftUI's WebView on iOS 26. In many websites, the top/bottom content is unaccessible due to being under the app's toolbars. It feels like the WebView doesn't really understand the safe areas where it's being shown, because the content should start right below the navigation bar, and only when the user scrolls down, the content should move under the bar (but it's always reachable if the users scroll back up). Here's a demo of the issue: Here's a 'fix' by ensuring that the content of the WebView never leaves its bounds. But as you can see, it feels out of place on iOS 26 (would be fine on previous OS versions if you had a fully opaque toolbar): Code: struct ContentView: View { var body: some View { NavigationStack { WebView(url: URL(string: "https://apple.com")).toolbar { ToolbarItem(placement: .primaryAction) { Button("Top content covered, unaccessible.") {} } } } } } Does anyone know if there's a way to fix it using some sort of view modifier combination or it's just broken as-is?

Hello, I've a question about performance when trying to render lots of items coming from SwiftData via a @Query on a SwiftUI List. Here's my setup: // Item.swift: @Model final class Item: Identifiable { var timestamp: Date var isOptionA: Bool init() { self.timestamp = Date() self.isOptionA = Bool.random() } } // Menu.swift enum Menu: String, CaseIterable, Hashable, Identifiable { var id: String { rawValue } case optionA case optionB case all var predicate: Predicate<Item> { switch self { case .optionA: return #Predicate { $0.isOptionA } case .optionB: return #Predicate { !$0.isOptionA } case .all: return #Predicate { _ in true } } } } // SlowData.swift @main struct SlowDataApp: App { var sharedModelContainer: ModelContainer = { let schema = Schema([Item.self]) let modelConfiguration = ModelConfiguration(schema: schema, isStoredInMemoryOnly: false) return try! ModelContainer(for: schema, configurations: [modelConfiguration]) }() var body: some Scene { WindowGroup { ContentView() } .modelContainer(sharedModelContainer) } } // ContentView.swift struct ContentView: View { @Environment(\.modelContext) private var modelContext @State var selection: Menu? = .optionA var body: some View { NavigationSplitView { List(Menu.allCases, selection: $selection) { menu in Text(menu.rawValue).tag(menu) } } detail: { DemoListView(selectedMenu: $selection) }.onAppear { // Do this just once // (0..<15_000).forEach { index in // let item = Item() // modelContext.insert(item) // } } } } // DemoListView.swift struct DemoListView: View { @Binding var selectedMenu: Menu? @Query private var items: [Item] init(selectedMenu: Binding<Menu?>) { self._selectedMenu = selectedMenu self._items = Query(filter: selectedMenu.wrappedValue?.predicate, sort: \.timestamp) } var body: some View { // Option 1: touching `items` = slow! List(items) { item in Text(item.timestamp.description) } // Option 2: Not touching `items` = fast! // List { // Text("Not accessing `items` here") // } .navigationTitle(selectedMenu?.rawValue ?? "N/A") } } When I use Option 1 on DemoListView, there's a noticeable delay on the navigation. If I use Option 2, there's none. This happens both on Debug builds and Release builds, just FYI because on Xcode 16 Debug builds seem to be slower than expected: https://indieweb.social/@curtclifton/113273571392595819 I've profiled it and the SwiftData fetches seem blazing fast, the Hang occurs when accessing the items property from the List. Is there anything I'm overlooking or it's just as fast as it can be right now?

We've started hitting this limitation when submitting builds using Xcode Cloud. ITMS-90382: Upload limit reached - The upload limit for your application has been reached. Please wait 1 day and try again. We generate TestFlight builds for every PR (builds from PR get sent to QA & devs) & for every merge (builds get sent to everybody in the team). Is there any way to know what's the limit so we can try to work around it? Edit: I've just checked, and TestFlight only reports 19 builds that are expiring in 90 days (aka were uploaded within the last 24h). Is the limit that low?

Recently Xcode Cloud has stopped showing new branches on the branch picker. For example, I still see our main branch on the list, but branches that I pushed recently do not appear when trying to generate a manual build. We have another app where none of the branches appear, and the same app (with a different bundle ID we use for Production, they all appear except for the new ones). The GitHub integration seems fine since when PRs are merged to main, all workflows that listen to changes to main work fine, and on the Settings I can see that the last access to the GitHub repository is from a few minutes ago when pushing new things. The same issue happens on the integration of Xcode Cloud inside Xcode, none of the new branches is listed there. Looks like the issue is on whatever lists the branches available. Has anyone noticed this?

For ages, we've been using appStoreReceiptUrl to detect if the app was installed from TestFlight or not, but now that's deprecated. Since we have a strict policy of no warnings on the project, we need to find a way to check if the app was installed from TestFlight or from the App Store. Does anyone know what's the new way to do so? I thought about using MarketplaceKit.AppDistributor.testFlight but to use MarketplaceKit you need to jump through hoops that our app really doesn't need to - we don't distribute outside of the App Store. Any ideas are much appreciated! 🙏

I'm having a lot of performance issues with SwiftUI Lists and I can't seem to find any solution. Currently, if you have a List with 10_000 items and try to filter it, the app hangs for 1 second at the beginning of filtering, looking at Instruments it seems to be an issue with the underlying UITableView to perform the animations. Here's a very tiny example to demo the issue: struct Item: Identifiable, Hashable {     let title: String     var id: String { title } } @main struct ListFilteringDemoApp: App {     private let allItems = (0...10_000).map { _ in Item(title: UUID().uuidString) }     @State var searchQuery: String = ""     var filteredItems: [Item] {         if searchQuery.isEmpty {             // No filter applied             return allItems.filter { _ in true }         } else {             return allItems.filter { item in item.title.localizedCaseInsensitiveContains(searchQuery)             }         }     }     var body: some Scene {         WindowGroup {             NavigationView {                 List(filteredItems) { item in                     Text(item.title).id(item)                 }                 .navigationTitle("Filtering")                 .searchable(text: $searchQuery, placement: .navigationBarDrawer(displayMode: .always))             }         }     } } I know that having 10_000 items in an array is not common. But using Core Data with a @FetchRequest, having 10_000 items is very easy to achieve for the kind of app that I'm building, and the issue is the same. The issue is present on device (iPhone 12 Pro, iOS 15.1), macOS and iOS Simulator. I've two questions: Is there a better way to filter a list while searching? If the answer is no, is there any way to prevent the animations on a List while being filtered to try to improve the performance? Thanks! PS: For Apple folks, I've opened a feedback which includes a sample project to reproduce the issue and a saved Instruments .trace. Number: FB9763003

For the past few days we've been observing a degraded performance on Xcode Cloud. Some builds get queued for hours and never start. I just cancelled one that's been queued for an hour and a half: Is this a known issue?
