I have an iOS project based on SwiftUI in which almost all code is organised in Packages. With Xcode 26.2 and 26.3, I can preview all SwiftUI views without issues. With Xcode 26.4, the same previews don't work, in the canvas appears this error message: "Cannot preview in this file. Could not find target description for “TaskListView.swift”". The explanation is: "The list of source files that produce object files did not contain this file to be previewed. Check to make sure it is not excluded using the EXCLUDED_SOURCE_FILE_NAMES build setting." If I add a SwiftUI view to the main project files (not in a package), the preview works as expected. Is it an Xcode 26.4 regression? Or do I need to modify some configuration file?

Good day! When your project have total 887 or more SPM local targets and then you try to build it, xcodebuild will be crash.

Here you can open sample project: Just Package.swift with SPM 900 targets Open Package.swift via Xcode 26 any beta and try to build Xcode workspace with SPM 900 targets Open MyApp.xcworkspace and try to build You can also make by self the Package.swift (also make required directories for SPM): // swift-tools-version: 5.9 import PackageDescription // let count = 800 // no crash let count = 900 // crash let targetsNames = (1...count).map { "Pkg1Target\($0)" } let targets = targetsNames.map { Target.target(name: $0) } let package = Package( name: "Pkg1TargetLibrary", platforms: [.iOS(.v16)], products: [ .library(name: "Pkg1TargetLibrary", targets: targets.map(\.name)), ], targets: targets )

Previews seemed to be working okay. However, I wanted to test out some changes inside of a package that I'm working on for work, but in a lighter project since in our main project (where I have the package pulled in locally for now) is just too big to have the previews render in a decent amount of time. So, I opened a small project that was already importing that package and was set to 'Up to Next Major', but I switched that to 'branch' and added my branch. This is the second time I've done that and it causes Xcode to freak out in terms of the previews. This is the code I have: import SwiftUI extension EnvironmentValues { @Entry var trailingDescriptionColorToken: Color = .secondary } extension View { func updateTrailingDescriptionColor(to colorToken: Color, when trigger: Bool) -> some View { environment(\.trailingDescriptionColorToken, trigger ? colorToken : .secondary) } } // MARK: - ListItemDescription public struct ListItemDescription: View { @Environment(\.trailingDescriptionColorToken) var trailingDescriptionColorToken let description: String init(_ description: String) { self.description = description } public var body: some View { Text(description) .font(.caption) .foregroundStyle(trailingDescriptionColorToken) } } struct ContentView: View { @State private var isError = false var body: some View { VStack { Button("Error Trigger") { isError.toggle() } ListItemDescription("Description") .updateTrailingDescriptionColor(to: .red, when: isError) } .padding() } } #Preview { ContentView() } As soon as I tap the button to toggle the isError state property, that causes the preview canvas to indefinitely load and spin eventually leading to a crash. This is infuriating as I've just wasted a ton of time at work trying to figure out what's going on. Xcode and SPM is so fragile and delicate that at this point I feel like if I breathe on it wrong it'll break. I'm not sure what fixed it last time. Nothing in Xcode makes sense anymore. How to I resolve this please?

Is anyone have this problem on xcode 26 ? Undefined symbol: _swift_FORCE_LOAD$_swiftCompatibility50 Undefined symbol: _swift_FORCE_LOAD$_swiftCompatibility51 Undefined symbol: _swift_FORCE_LOAD$_swiftCompatibility56 Undefined symbol: _swift_FORCE_LOAD$_swiftCompatibilityConcurrency Undefined symbol: _swift_FORCE_LOAD$_swiftCompatibilityDynamicReplacements

Hi everyone, yesterday i installed some package in my ios app , but i had a lot of problems to compile , due to reset my branch and get started from 0. My project have pods with firebase, lottie, instana and truskit but now, when a i try to run my project, xcode show "Unable to resolve module dependency" into LOTTIE, INSTANA, TRUSKIT, FIREBASE . I visited a lot of forums and websites, and i tried the followings steps: Pod deintegrate pod repoupdate pod install Clean build folder Delete derived data but isnot working. Also,I reinstalled xcode , 2 versions , i "re"clone my repository and the issue persist. Sorry, my english is basic only

It's my first time I am configuring the Xcode cloud to build my project. Here is the crash and stack trace Stack trace One thing I noticed when I setup Xcode Cloud - it asked me to grant access to every public github library I have as dependency, I can't do that, as I am not owner or member of those libraries (firebase, swift algorithms, etc) when I tapped "Continue" there was an alert saying if I continue without granting access CI might not be able to fetch dependencies

For me it looks like Xcode 26 has problems reading SPM packages from a locally hosted BitBucket git solution. While Xcode 16 work perfectly fine, Xcode 26 fails to load and gives "Server SSH Fingerprint Failed to Verify" as error description. Cleaning build data and DerivedData sometimes makes loading work. Any change in Package dependencies will break it again. Anyone having same problems? How do you handle it?

Hi, We are evaluating Swift Package Manager for distributing private packages to external customers. Our use case requires enterprise-grade authentication beyond standard username/password, personal access token, or SSH key based authentication. Our current authentication model relies on request signing / IAM-based authorization rather than standard Git credentials. From what we can tell, Swift Package Manager does not appear to expose a built-in mechanism for custom authentication hooks during package resolution. Because of that, we started exploring whether a Git-based workaround might be possible, such as: using a custom Git URL scheme handling that scheme through a Git remote helper using a Git credential helper or related Git configuration for authentication We tried a proof of concept along these lines, but Xcode did not seem to recognize or resolve the package correctly. We are trying to understand what is officially supported and what is not. Our questions are: Does Xcode / Swift Package Manager support package dependencies that rely on custom Git URL schemes? During package resolution, does Xcode honor system Git configuration for remote helpers and credential helpers? Is there any difference in support between: adding the package through the Xcode UI resolving through swift package resolve resolving through xcodebuild For private package distribution, is there any Apple-recommended approach when authentication requires request signing or a custom IAM-based flow instead of standard Git credentials? If custom Git authentication is not supported, should we assume the recommended path is to place an authenticated proxy or gateway in front of a standard Git or HTTPS endpoint instead? We are mainly trying to determine whether this direction is fundamentally unsupported in Xcode / SwiftPM, or whether there is a supported way to integrate enterprise authentication into package resolution. Any guidance would be appreciated. Thanks!

Hi everyone, I’m building a SwiftUI app using NavigationStack and running into a weird nav bar issue. For the setup I have a 'home' screen with a vertical ScrollView and a large edge-to-edge header that extends under the top safe area (using .ignoresSafeArea(edges: .top)). I also have a 'detail' screen with a similar immersive layout, where the header/poster image sits at the top and the ScrollView also extends under the top area. I’m using the native navigation bar on both screens and default back button, not a custom nav bar, and I’m not manually configuring UINavigationBarAppearance, I'm just relying on SwiftUI’s default/automatic toolbar behavior. The problem I’m facing is when I push from home to the detail screen, the top nav area briefly flickers and shows the system navigation bar/material background (white in light mode, black in dark mode). It’s clearly the system material, not the poster/image underneath. The screen initially renders with that nav bar state (white/dark), and only after I start scrolling does it correct itself and visually align with the header/background behind it. What I'm thinking is that maybe the detail screen initially renders with systemBackground, so the nav bar uses its default (standard) appearance on the first frame, and only after layout/interaction, once the image-derived background settles, does it switch to the correct scroll-edge/transparent style. One important thing, if I hide the nav bar on the detail screen using .toolbar(.hidden, for: .navigationBar), the issue disappears completely. So this seems specifically tied to the native nav bar’s initial render/appearance timing during the push, rather than just the layout or image loading. I’d prefer to keep the native nav bar and back button rather than implement a custom approach. Has anyone faced this issue before, or is there a correct way to structure edge-to-edge content under the nav bar so it renders properly on first push?

Hello everyone, My app has been stuck in "Waiting for Review" for a long time, and I would like to know whether this is normal or whether I should take any additional action. App name: ختمة يومية Submission date: March 7, 2026 at 3:34 AM Current status: Waiting for Review I have already completed the required app information, including the TestFlight/App Review details, and there are no visible missing items in App Store Connect. I would like to ask: Is this review delay normal at the moment? Has anyone experienced a similar delay recently? Is there anything else I should check in App Store Connect? Would contacting App Review again help in this case? I would appreciate any advice or shared experience. Thank you.

Is it possible to build localization into console apps, developed in SwiftUI in Xcode26. I have created a catalog, (.xcstrings file) with an English and fr-CA string. I have tried to display the French text without success. I am using the console app to test a package which also has English/French text. English text works fine in both package and the console main, but I cannot generate the French. From what I can discover so far it's not possible without bundling it as a .app, (console app). Looking for anyone who has crossed this bridge.

Trying out the new package trait support in Xcode 26.4 and it seems like the default traits for the package are being enabled even when explicitly set to disabled. At first I thought it was something wonky in the Xcode UI around the new support for traits. I've been able to replicate the issue with just two Swift packages, so no Xcode UI for setting the traits. Feature package // swift-tools-version: 6.3 import PackageDescription let package = Package( name: "MyAwesomeFeature", platforms: [ .macOS(.v26) ], products: [ .library( name: "MyAwesomeFeature", targets: ["MyAwesomeFeature"] ) ], traits: [ .trait(name: "SomeBetaFeature"), .default(enabledTraits: ["SomeBetaFeature"]), ], targets: [ .target( name: "MyAwesomeFeature" ), ], swiftLanguageModes: [.v6] ) For the sake of testing I've given it a simple object that just prints if the trait is enabled Inside MyAwesomeFeature public struct SomeObject { func printTraitStatus() { #if SomeBetaFeature print("Beta feature enabled") #else print("Beta feature disabled") #endif } } I then have a second package that depends on the feature and produces an executable // swift-tools-version: 6.3 import PackageDescription let package = Package( name: "SwiftPackageBasedProgram", platforms: [ .macOS(.v26), ], products: [], dependencies: [ .package(name: "MyAwesomeFeature", path: "../MyAwesomeFeature", traits: []) ], targets: [ .executableTarget( name: "MyAwesomeProgram", dependencies: [ .product(name: "MyAwesomeFeature", package: "MyAwesomeFeature") ] ), ], swiftLanguageModes: [.v6] ) If I run MyAwesomeProgram from the command line with swift run I get the output I would expect Build of product 'MyAwesomeProgram' complete! (6.10s) Inside SwiftPM program Beta feature disabled If I run the same program from within Xcode though Inside SwiftPM program Beta feature enabled Program ended with exit code: 0 I've got the sample project available here if anyone wants to try it out. Has anyone else come across anything like this? Very possible I'm just missing something.

When I try to build my iOS app using Xcode Cloud, it encounters an error when trying to resolve packages: an out-of-date resolved file was detected at [path to package.resolved], which is not allowed when automatic dependency resolution is disabled; please make sure to update the file to reflect the changes in dependencies Looking at my package.resolved file, it all seems to be in order. What can I do to fix it?

Hi there, I recently updated to the latest version of macOS Tahoe 26.3. Since then, Xcode is not able to resolve my Swift Package dependencies anymore. We use SSH for all our Github hosted packages. When package resolution is running, we randomly have Failed to verify SSH fingerprint on some remote package. Nothing has changed and it worked perfectly with Tahoe 26.2. The SSH have been reconfigured and known hosts have been verified. Is something changed between those 2 versions or is it a bug ?

When building a SwiftUI project in Xcode 26.3, Swift compilation fails in the Release configuration with Optimization Level set to -O, when the iOS deployment target is lower than iOS 26 (e.g. iOS 16, 17, or 18). The failure occurs when using a generic class conforming to ObservableObject that contains a @Published property. The same code: Compiles successfully in Xcode 16.3 (Release, -O) with iOS 16/17/18 Compiles successfully in Xcode 26.x when the deployment target is set to iOS 26 Compiles successfully in Xcode 26.x Debug configuration (-Onone) Compiles successfully in Xcode 26.x Release when optimization is disabled (-Onone) However, in Xcode 26.3, the build consistently fails in Release (-O) when targeting iOS 16, 17, or 18. This appears to be a Swift compiler optimization issue related to generics, ObservableObject, @Published, and back-deployment to iOS versions prior to iOS 26. STEPS TO REPRODUCE Create a new SwiftUI App project using Xcode 26.3. Leave all project settings at default (Swift version 5). Set the iOS Deployment Target to iOS 16, 17, or 18. Use the following minimal code: import SwiftUI internal import Combine @MainActor class CommonViewModel<Item>: ObservableObject { @Published var listArray = [Item]() } class ContentViewModel: CommonViewModel<String> { func reloadData() { self.listArray = ["1"] } } struct ContentView: View { @StateObject private var viewModel = ContentViewModel() var body: some View { Color.clear .onAppear { viewModel.reloadData() } } } Build and run the app using the Release configuration.

I use spm manage swift package, now i want my macos app support arm64e,so i add arm64e in Build Srtting -> Architectures. but i got error Could not find module 'SwiftyJSON' for target 'arm64e-apple-macos'; found: arm64-apple-macos, x86_64-apple-macos Apparently, if no limit in Package.swift, SPM will only compile versions for x86 and ARM64 architectures by default. now, how should I configure SPM to compile the arm64e version? thanks

I am reporting a reproducible performance issue in iOS 18.6 where synchronizing the scroll position of two Chart views via chartScrollPosition(id:) causes a complete redraw loop when custom AxisMarks are used. This occurs even when the axis marks are technically "hidden," leading to significant frame drops and stuttering on modern hardware like the iPhone 15. Environment Device: iPhone 15 OS: iOS 18.6 (22G86) Frameworks: SwiftUI, Swift Charts, Observation The Issue When using a shared @Observable state to sync two charts, the scrolling is fluid only if the axes are at their default settings. As soon as a custom AxisMarks block is added to either chart, the following behavior is observed: Diffing Failure: The framework appears unable to maintain the identity of the axis components during the scroll update. Redraw Loop: Instead of an incremental scroll translation, the diffing algorithm triggers a full reload/re-render of both charts on every scroll offset change. Impact: CPU spikes to 100% and the UI becomes unresponsive. This happens even if the custom AxisMarks is used solely to hide the axis (e.g., AxisMarks { _ in }), suggesting the issue is with the custom declaration itself rather than the complexity of the marks being rendered. Steps to Reproduce Create two Chart views in a VStack. Bind both to a single @Observable property using .chartScrollPosition(id: $state.pos). Add any .chartXAxis { AxisMarks(...) { ... } } modifier. Scroll either chart; observe the stuttering. import SwiftUI import Charts import Observation @Observable class ChartState { var scrollPos: Date = .now } struct PerformanceBugView: View { @State private var state = ChartState() var body: some View { VStack { Chart(data) { ... } .chartScrollPosition(id: $state.scrollPos) .chartXAxis { // This custom mark triggers the performance issue AxisMarks { _ in AxisValueLabel() } } Chart(data) { ... } .chartScrollPosition(id: $state.scrollPos) } } } Questions for the Community/Apple Engineers: Is there a way to provide a stable identifier to AxisMarks to prevent them from being treated as "new" during a scroll update? Why does even an empty AxisMarks block (used for hiding) trigger a layout invalidation that standard axes do not? Are there internal optimizations for chartScrollPosition that are bypassed when the axis layout is customized?

My project uses about 10 local packages. When Xcode determins its dependencies graph it includes project Foo (a package) and project Foo_Foo (???). This is a no op for normal builds, but causes the Foo package to be linked twice for test builds which then fail due to duplicate symbols. Nowhere in my repository is Foo_Foo defined or reference. Nowhere in the .xcodeproj/ folder is there mention of Foo_Foo. What am I doing wrong?

Can't able to run the Create ML for training and I upgraded to MacOS 26.3 beta and I have tried older and newer
