I just finished my first mobile app using .Net Maui. I have created all of the required certificatee, identifier, and profile in my Apple developer account and downloaded them to my MacAir. On my Windows machine I connect to my MacAir in VS2022 and build my release. Then I go to publish and I get this error: Cannot create an IOS archive 'AgentManagerMobile'. Process cannot be executed on XMA server. MessagingRemoteException: An error occurred on client Build1647067 while executing a reply for topic xvs/build/16.4.7067/execute-task/{AppName}/399e8ad002fWriteAppManifest ArgumentNullException: Value cannot be null. Parameter name: path2 What is parameter path2? Can anyone help with solving this? Thanks, Phill

I am trying to add complication feature to my watchOS app. I need to add some keys to the Info.plist. Project Navigator - no Info.plist file (as expected) Target watchOS > Build Settings > Info.plist values. I am unable to add a value. Hovering over a row does NOT show small '+' or '-' icons. How do I edit the Info.plist?

I have an app, which is depended on custom SDK. Custom SDK has dependencies, included all dependencies in Podspec and custom framework/static lib ios.vendored_frameworks. here I sample of my pod spec Pod::Spec.new do |s| s.name = "SDK" s.version = "1.0.1" s.summary = "SDK" s.source = { :git => "https://github.com/ABC/SDK.git", :tag => "v"+s.version.to_s } s.platform = :ios s.ios.deployment_target = '16.0' s.swift_version = '4.2' s.static_framework = true s.frameworks = 'Security' s.frameworks = 'CoreLocation' s.requires_arc = true s.module_name = 'SDK' s.library = 'z' s.default_subspec = 'Shared' s.subspec 'Shared' do |shared| shared.ios.vendored_frameworks = 'SDKLib.xcframework' shared.dependency 'CocoaAsyncSocket', '~> 7.4' shared.dependency 'CocoaHTTPServer' shared.dependency 'SocketRocket', '~> 0.6' shared.dependency 'QNNetDiag' shared.dependency 'SAMKeychain' shared.dependency 'AFNetworking/Reachability', '~> 4.0' shared.dependency 'AFNetworking/Serialization', '~> 4.0' shared.dependency 'AFNetworking/Security', '~> 4.0' shared.dependency 'AFNetworking/NSURLSession', '~> 4.0' shared.dependency 'CocoaMQTT' shared.dependency 'Starscream', '~> 4.0.8' shared.dependency 'TrustKit' shared.dependency 'Firebase/Analytics' end end below error I am getting while linking lib

Hello, I'm seeing many errors like this in the Xcode debug console when I build and run my app: ERROR: Unrecognized attribute string flag '?' in attribute string "T@"NSString",?,R,C" for property debugDescription The app project makes heavy use of Logger(), and I suspect it is related to that logging in some way, but I haven't been able to narrow down the issue to specific log calls. I have Category, Subsystem and Timestamp enabled in the Xcode console, but none of those are displayed for this output. What causes this? Or how can I better narrow down the source?

I am at a loss. I have looked at examples, and I have used chat/cursor. I cannot figure out how to target the transform/position of a Reality Composer Pro project when adding it to an ARView in iOS. I have a test red sphere working perfectly for raycast positioning. When I pass the same variables (tested with print out) to the Entity or Anchor position/transform nothing changes. It seems that, no matter what, the content of the Reality Composer Pro project is placed where the camera view initialized. How do I actually interact with its position? I just want to be able to tap the screen and place the RCP wherever I want.

XCode 13 is super slow, build time is 10~20 times longer than Xcode 12。The worst release ever.

Hi, I'm developing an app and after I change the app icon it's appear this error. Why? Previously I noticed, and it still does, that in the app settings it does not keep the LauncScreen.storyboard. In the drop-down menu it appears but as soon as I change screen it loses it. I don't know what to do.... Thanks!

Environment: Xcode v. 16.2; Swift version 6+ Scenario: I have an .xcodeproj within an .xcsworkingspace that must follow the 'command-line' paradigm outside the sandbox. My UnitTest (using the newer 'Swift Test' vs 'XCTest') is hitting runtime fatal errors due to sandbox violations. Here's a typical error line from the compiler: 1 duplicate report for Sandbox: chmod(41377) deny(1) file-read-data /Users/Ric/Library/.. I've set the .entitlement to ignore sandbox: <key>com.apple.security.app-sandbox</key> <false/> I also created a shell script in the project build phase to access my TestData which was copied via a Build Phase: #!/bin/bash BUILD_DIR="${BUILT_PRODUCTS_DIR}" TEST_DATA="${SRCROOT}/SwiftModelTest/TestData" mkdir -p "${BUILD_DIR}/TestData" cp -R "${TEST_DATA}/" "${BUILD_DIR}/TestData/" What do I need to allow real-time Testing of my code without worrying about the Sandbox?

Hi Folks... I’m 81 and trying to learn Swift. I taught programming 40 years ago but haven’t coded for over 20 years. As you can see in the subject line, I’m running Sequoia 15.3 on a MacBook Air and learning and running code samples from “IOS 18 Programming for Beginners” by Ahmad Sahar. When I run the code samples, the variable settings show up in the Debug area but none of the output even though Sahar’s book states that it should. I’m wondering if I’m doing some stupid newbie thing or if it might be a bug? Anyone seen this one?

I have two apps that I have been supporting for some time now. When Xcode 15.3 came out the app started crashing. No code changes whatsoever. I could not figure out why it would crash in 15.3. I just downloaded Xcode 15.2 and kept using 15.2. I have stayed recent with other apps, but I have just used 15.2 for this app. I just upgraded my OS to sequoia which also upgrades my Xcode to 16.2. To my surprise 15.2 is not supported on sequoia, so I only have 2 choices. setup a VM with an older OS and Xcode 15.2 or figure out why the app crashes on anything beyond 15.2 Like I said no problem running on Xcode 15.2 What gets shown in the error starts off with this: Unable to Install “Gatlinburg Pocket Guide” Domain: IXUserPresentableErrorDomain Code: 1 Failure Reason: Please try again later. Recovery Suggestion: Failed to load Info.plist from bundle at path .... Hoping someone has some suggestions for me or has seen this happen before. Thanks.

I recently upgraded to macOS 14.7.2, triggering an upgrade to Xcode 16.2 and its command line tools. My open source project builds and runs fine in Xcode. But when I tested the CMake build, it failed looking for standard c++ headers. I asked on stackoverflow but no solutions so far. Any thoughts here?

I am able to setup and schedule a background refresh task as well as manually trigger it via Xcode and the simulator tied to my iPhone 11 Pro test phone using the e -l objc -- (void)[[BGTaskScheduler sharedScheduler] _simulateLaunchForTaskWithIdentifier: However, it won't execute on the app on it's own. And yes, the pinfo.list entries are correct and match! I know the scheduler is not exact on timing but it's just not executing on its own. Since I can trigger manually it I'm pretty sure the code is good but I must be missing something. I created an observable object for this code and the relevant parts look like this: class BackgroundTaskHandler: ObservableObject { static let shared = BackgroundTaskHandler() var taskState: BackgroundTaskState = .idle let backgroundAppRefreshTask = "com.opexnetworks.templateapp.shell.V1.appRefreshTask" func registerBackgroundTask() { BGTaskScheduler.shared.register(forTaskWithIdentifier: backgroundAppRefreshTask, using: nil) { task in self.handleAppRefresh(task: task as! BGAppRefreshTask) } self.updateTaskState(to: .idle, logMessage: "✅ Background app refresh task '\(backgroundAppRefreshTask)' registered.") BGTaskScheduler.shared.register(forTaskWithIdentifier: backgroundTaskIdentifier, using: nil) { task in self.handleProcessingTask(task: task as! BGProcessingTask) } self.updateTaskState(to: .idle, logMessage: "✅ Background task identifier '\(backgroundTaskIdentifier)' registered.") } // Handle the app refresh task private func handleAppRefresh(task: BGAppRefreshTask) { self.updateTaskState(to: .running, logMessage: "🔥 app refresh task is now running.") PostNotification.sendNotification(title: "Task Running", body: "App refresh task is now running.") let queue = OperationQueue() queue.maxConcurrentOperationCount = 1 let operation = BlockOperation { self.doSomeShortTaskWork() } task.expirationHandler = { self.updateTaskState(to: .expired, logMessage: "💀 App refresh task expired before completion.") PostNotification.sendNotification(title: "Task Expired", body: "App refresh task expired before completion \(self.formattedDate(Date())).") operation.cancel() } operation.completionBlock = { if !operation.isCancelled { self.taskState = .completed } task.setTaskCompleted(success: !operation.isCancelled) let completionDate = Date() UserDefaults.standard.set(completionDate, forKey: "LastBackgroundTaskCompletionDate") self.updateTaskState(to: .completed, logMessage: "🏁 App refresh task completed at \(self.formattedDate(completionDate)).") PostNotification.sendNotification(title: "Task Completed", body: "App refresh task completed at: \(completionDate)") self.scheduleAppRefresh() // Schedule the next one } queue.addOperation(operation) } func scheduleAppRefresh() { // Check for any pending task requests BGTaskScheduler.shared.getPendingTaskRequests { taskRequests in let refreshTaskIdentifier = self.backgroundAppRefreshTask let refreshTaskAlreadyScheduled = taskRequests.contains { $0.identifier == refreshTaskIdentifier } if refreshTaskAlreadyScheduled { self.updateTaskState(to: .pending, logMessage: "⚠️ App refresh task '\(refreshTaskIdentifier)' is already pending.") // Iterate over pending requests to get details for taskRequest in taskRequests where taskRequest.identifier == refreshTaskIdentifier { let earliestBeginDate: String if let date = taskRequest.earliestBeginDate { earliestBeginDate = self.formattedDate(date) } else { earliestBeginDate = "never" } self.updateTaskState(to: .pending, logMessage: "⚠️ Pending Task: \(taskRequest.identifier), Earliest Begin Date: \(earliestBeginDate)") } // Optionally, show a warning message to the user in your app PostNotification.sendNotification(title: "Pending Tasks", body: "App refresh task is already pending. Task scheduling cancelled.") return } else { // No pending app refresh task, so schedule a new one let request = BGAppRefreshTaskRequest(identifier: refreshTaskIdentifier) request.earliestBeginDate = Date(timeIntervalSinceNow: 15 * 60) // Earliest in 15 minutes do { try BGTaskScheduler.shared.submit(request) self.taskState = .scheduled self.updateTaskState(to: .scheduled, logMessage: "✅ App refresh task '\(refreshTaskIdentifier)' successfully scheduled for about 15 minutes later.") PostNotification.sendNotification(title: "Task Scheduled", body: "App refresh task has been scheduled to run in about 15 minutes.") } catch { print("Could not schedule app refresh: \(error)") self.taskState = .failed self.updateTaskState(to: .failed, logMessage: "❌ Failed to schedule app refresh task.") } } } } // Short task work simulation private func doSomeShortTaskWork() { print("Doing some short task work...") // Simulate a short background task (e.g., fetching new data from server) sleep(5) print("Short task work completed.") } In my AppDelegate I trigger the registerBackground task in the didFinishLaunchingWithOptions here: BackgroundTaskHandler.shared.registerBackgroundTask() And I scheduled it here in the launch view under a task when visible: .task { BackgroundTaskHandler.shared.scheduleAppRefresh() } I've also tried the last in the AppDelegate after registering. either way the task schedules but never executes.

For a number of years we have managed our iOS projects using Sourcetree and command line Git or Visual Code. I wanted to use the XCode Source control for a more integrated development experience. However, depite the fact that the Git repo is in the root of the XCode project tree, XCode cannot see that repo in the Source Control panel. Source Control IS enabled in settings I tried to add the repo using. Integrate >> New Git Repository. but Xcode then says there is an existing repository and does nothing. How do I add the existing local repo into the Xcode environment or does it now need to be managed only externally because it was not created using Xcode ? Thanks

So I have a MacOS application that was working just fine before Xcode 16. The Widgets are not working anymore. The main application and the widgets share a file in a common App Group. The widget app now get a permission error when accessing the file. Also, the Widget Kit simulator keeps crashing. I also try to start a new project in Xcode, add a target with a Widget extension with an App Intent and run it, and it also crashes. Sometimes, it doesn't crash but just display the error: "Failed to load widget. The operation couldn't be completed. (WidgetKit_Simulator.WidgetDocument.Error error 2.). Edited to attach WidgetKit error log widgetKitError.txt

Has anyone used the Xcode AI coding assistant called CodeNext? It is a free tool and can be downloaded at codenext.ai. It autocompletes code, has a chat function, and can use any AI model which is a cool feature. Curious to know your thoughts and what other tools you've used.
