Every time macOS goes to sleep the processes get suspended which is expected. But during the sleep period, all processes keep coming back and they all get a small execution window where they make some n/w requests. Regardless of what power settings i have. It also does not matter whether my app is a daemon or not Is there any way that i can disable this so that when system is in sleep, it stays in suspended, no intermittent execution window? I have tried disabling Wake for network access setting but processes still keep getting intermittent execution window. Is there any way that i can prevent my app from coming back while in sleep. I don't want my app to get execution window, perform some executions and then get suspended not knowing when it will get execution window again?

Currently I am trying to find a work around to fetch data from server and update user defaults when app is forced quit. Can anyone suggest for this ?

The application is placed into the idle state. Subsequently, the device enters a sleep state. While the device is in sleep, App start background task within the application successfully receives its expirationHandler callback. App received the expiration callback and App called the end BGtask OS did not released the Assertion. Resulting in App getting terminated by the OS for exceeding the BG task Apple Feedback- FB19192371

So i am pretty new to Xcode, but i have been using Python and other language for some while. But I am quite new to the game of view and view control. So it may be that i have over complicated this a bit - and it may be that I have some wrong understanding of the dependencies and appcontroller (that i thought would be a good idea). So here we have a main file we call it app.swift, we have a startupmanager.swift, a appcoordinator and a dependeciescontainer. But it may be that this is either a overkill - or that I am doing it wrong. So my thought was that i had a dependeciecontainer, a appcoordinator for the views and a startupmanager that controll the initialized fetching. I have controlled the memory when i run it - checking if it is higher, lower eg - but it was first when i did my 2 days profile i saw a lot of new errors, like this: Fikser(7291,0x204e516c0) malloc: xzm: failed to initialize deferred reclamation buffer (46). and i also get macro errors, probably from the @Query in my feedview. So my thought was that a depencecie manager and a startupmanager was a good idea together with a app coordinator. But maybe I am wrong - maybe this is not a good idea? Or maybe I am doing some things twice? I have added a lot of prints and debugs for checking. But it seems that it starts off to heavy? import SwiftUI import Combine @MainActor class AppCoordinator: ObservableObject { @Published var isLoggedIn: Bool = false private var authManager: AuthenticationManager = .shared private var cancellables = Set<AnyCancellable>() private let startupManager: StartupManager private let container: DependencyContainer @Published var path = NavigationPath() enum Screen: Hashable, Identifiable { case profile case activeJobs case offers case message var id: Self { self } } init(container: DependencyContainer) { self.container = container self.startupManager = container.makeStartupManager() setupObserving() startupManager.start() print("AppCoordinator initialized!") } private func setupObserving() { authManager.$isAuthenticated .receive(on: RunLoop.main) .sink { [weak self] isAuthenticated in self?.isLoggedIn = isAuthenticated } .store(in: &cancellables) } func userDidLogout() { authManager.logout() path.removeLast(path.count) } func showProfile() { path.append(Screen.profile) } func showActiveJobs() { path.append(Screen.activeJobs) } func showOffers() { path.append(Screen.offers) } func showMessage() { path.append(Screen.message) } @ViewBuilder func viewForDestination(_ destination: Screen) -> some View { switch destination { case .profile: ProfileView() case .activeJobs: ActiveJobsView() case .offers: OffersView() case .message: ChatView() } } @ViewBuilder func viewForJob(_ job: Job) -> some View { PostDetailView( job: job, jobUserDetailsRepository: container.makeJobUserDetailsRepository() ) } @ViewBuilder func viewForProfileSubview(_ destination: ProfileView.ProfileSubviews) -> some View { switch destination{ case .personalSettings: PersonalSettingView() case .historicData: HistoricDataView() case .transactions: TransactionView() case .helpCenter: HelpcenterView() case .helpContract: HelpContractView() } } enum HomeBarDestinations: Hashable, Identifiable { case postJob case jobPosting var id: Self { self } } @ViewBuilder func viewForHomeBar(_ destination: HomeBarView.HomeBarDestinations) -> some View { switch destination { case .postJob: PostJobView() } } } import Apollo import FikserAPI import SwiftData class DependencyContainer { static var shared: DependencyContainer! private let modelContainer: ModelContainer static func initialize(with modelContainer: ModelContainer) { shared = DependencyContainer(modelContainer: modelContainer) } private init(modelContainer: ModelContainer) { self.modelContainer = modelContainer print("DependencyContainer being initialized at ") } @MainActor private lazy var userData: UserData = { return UserData(apollo: Network.shared.apollo) }() @MainActor private lazy var userDetailsRepository: UserDetailsRepository = { return UserDetailsRepository(userData: makeUserData()) }() @MainActor private lazy var jobData: JobData = { return JobData(apollo: Network.shared.apollo) }() @MainActor private lazy var jobRepository: JobRepository = { return JobRepository(jobData: makeJobData(), modelContainer: modelContainer) }() @MainActor func makeUserData() -> UserData { return userData } @MainActor func makeUserDetailsRepository() -> UserDetailsRepository { return userDetailsRepository } @MainActor func makeStartupManager() -> StartupManager { return StartupManager( userDetailsRepository: makeUserDetailsRepository(), jobRepository: makeJobRepository(), authManager: AuthenticationManager.shared, lastUpdateRepository: makeLastUpdateRepository() ) } @MainActor func makeJobData() -> JobData { return jobData } @MainActor func makeJobRepository() -> any JobRepositoryProtocol { return jobRepository } @MainActor private lazy var jobUserData: JobUserData = { return JobUserData(apollo: Network.shared.apollo) }() @MainActor private lazy var jobUserDetailsRepository: JobUserDetailsRepository = { return JobUserDetailsRepository(jobUserData: makeJobUserData()) }() @MainActor func makeJobUserData() -> JobUserData { return jobUserData } @MainActor func makeJobUserDetailsRepository() -> JobUserDetailsRepository { return jobUserDetailsRepository } @MainActor private lazy var lastUpdateData: LastUpdateData = { return LastUpdateData(apollo: Network.shared.apollo) }() @MainActor private lazy var lastUpdateRepository: LastUpdateRepository = { return LastUpdateRepository(lastUpdateData: makeLastUpdateData()) }() @MainActor func makeLastUpdateData() -> LastUpdateData { return lastUpdateData } @MainActor func makeLastUpdateRepository() -> LastUpdateRepository { return lastUpdateRepository } }```

My app uses SMAppService to register a privileged helper, the helper registers without errors, and can be seen in System Settings. I can get a connection to the service and a remote object proxy, but the helper process cannot be found in Activity Monitor and the calls to the proxy functions seem to always fail without showing any specific errors. What could be causing this situation?

I would like to implement an expression that pops out from the window to Immersive based on the following WWDC video. This video introduces the new features of visionOS 2.0 in the form of refurbishing Apple's sample app BOT-anist. https://developer.apple.com/jp/videos/play/wwdc2024/10153/?time=1252 In the video, it looks like ImmersiveSpaceAppModel is newly implemented. However, the key code is not mentioned anywhere. You pass appModel.robot as the from argument to the transform method of RealityViewContent. It seems that BOT-anist has been updated once and can be downloaded from the following URL, but there is no class such as ImmersiveSpaceAppModel implemented in this app either. https://developer.apple.com/documentation/visionos/bot-anist Has it been further updated again? Frankly, I'm not sure if it is possible to proceed as per the WWDC video. Translated with DeepL.com (free version)

I'm using libxpc in a C server and Swift client. I set up a code-signing requirement in the server using xpc_connection_set_peer_code_signing_requirement(). However, when the client doesn't meet the requirement, the server just closes the connection, and I get XPC_ERROR_CONNECTION_INTERRUPTED on the client side instead of XPC_ERROR_PEER_CODE_SIGNING_REQUIREMENT, making debugging harder. What I want: To receive XPC_ERROR_PEER_CODE_SIGNING_REQUIREMENT on the client when code-signing fails, for better debugging. What I’ve tried: Using xpc_connection_set_peer_code_signing_requirement(), but it causes the connection to be dropped immediately. Questions: Why does the server close the connection without sending the expected error? How can I receive the correct error on the client side? Are there any other methods for debugging code-signing failures with libxpc? Thanks for any insights!

For example, let’s propose an XPC service that can connect to websites. Suppose that I want to connect to Apple.com, microsoft.com, and ibm.com. Can 3 service objects be made between the service and client? Or does the service have to return an ID for each web connection, with the client needing to specify which connection ID along with a command?

I'm developing a macOS application that tracks the duration of a user's session using a timer, which is displayed both in the main window and in an menu bar extra view. I have a couple of questions regarding the timer's behavior: What happens to the timer if the user closes the application's window (causing the app to become inactive) but does not fully quit it? Does the timer continue to run, pause, or behave in some other way? Will the app nap feature stop the timer when app is in-active state? When the application is inactive and the system is either in sleep mode or locked, does the timer’s tolerance get affected? In other words, will the timer fire with any additional delay compared to its scheduled time under these conditions?

Recently, after updating the Developer app to the latest version, my iPad has been unable to open this app as it crashes immediately upon launch. Prior to the update, the app functioned normally. My device is an 11-inch iPad Pro from 2021, running iPadOS 17.3. I have tried troubleshooting steps such as reinstalling the app and restarting the device, but these actions have not resolved the issue. However, I need to use this specific version of the system, iPadOS 17.3, for software testing purposes and cannot upgrade the system. Other apps on my device work normally without any issues. Is there a solution to this problem? I have attempted to contact the developer support team in China, but they were also unable to provide a resolution. This issue is reproducible 100% of the time on my iPad.

Purpose I want to use launchd to run a shell script asynchronously every minute, but I'm encountering an issue where the job does not run, and I receive the error "Bootstrap failed: 5: Input/output error". I need help identifying the cause of this issue and how to configure launchd correctly. What I've done Created the shell script (test_ls_save.sh) The script is designed to list the contents of the desktop and save the output to a specified directory. #!/bin/bash DATE=$(date +%Y-%m-%d_%H-%M-%S) SAVE_DIR=/Users/test/Desktop/personal/log_gather FILE_NAME="ls_output_$DATE.log" ls ~/Desktop &gt; "$SAVE_DIR/$FILE_NAME" echo "ls output saved to $SAVE_DIR/$FILE_NAME" File permissions (ls -l output): -rwxr-xr-x 1 test staff 1234 Feb 17 10:00 /Users/test/Desktop/personal/log_gather/exec/test_ls_save.sh Created the launchd plist file (com.test.logTest.plist) The plist file is configured to execute the shell script every minute. &lt;key&gt;Label&lt;/key&gt; &lt;string&gt;com.test.logTest&lt;/string&gt; &lt;key&gt;ProgramArguments&lt;/key&gt; &lt;array&gt; &lt;string&gt;/bin/bash&lt;/string&gt; &lt;string&gt;-c&lt;/string&gt; /Users/test/Desktop/personal/log_gather/exec/test_ls_save.sh &lt;/array&gt; &lt;key&gt;StartInterval&lt;/key&gt; &lt;integer&gt;60&lt;/integer&gt; &lt;!-- Run every minute --&gt; File permissions (ls -l output): -rwxr-xr-x 1 test staff 512 Feb 17 10:00 /Users/test/Library/LaunchAgents/com.test.logTest.plist Ran the job with launchctl I used the following command to load the plist file into launchd: sudo launchctl bootstrap gui/$(id -u) /Users/test/Library/LaunchAgents/com.test.logTest.plist pc spec MacBook Pro Apple M1 16 GB RAM macOS 15.3 (Build 24D60) what I know The configuration has been set, but the launchd job is not running every minute as expected. I don't believe there is a mistake with the path. When I check the job using launchctl list, the job does not appear in the list. I don't know where the error log files are supposed to be. I checked /var/log/system.log, but there are no error logs. The .sh file runs fine by itself, but it cannot be executed via launchctl. Want to ask What could be the cause of the launchd job not running as expected? Also, is there a way to check where the logs are being output? If there is an error in the plist file configuration, which part should be modified? Specifically, what improvements should be made regarding environment variables and path settings? If my information is not enough, please tell me what is not enough!

I'm using flutter's inappwebview. All functions work on my simulator and phone, but when I submit for review, I get an answer saying infinite loading. How did it happen? I don't know what the problem is.

Hello everyone, I’m a new developer still learning as I go. I’m building a simple watchOS app that tracks Apple Watch battery consumption, records hourly usage data, and uses that information to predict battery life in hours. I’ve run into an issue where background refresh completely stalls after charging and never recovers, regardless of what I do. The only way to restore normal behavior is to restart the watch. Background refresh can work fine for days, but if the watch is charging and a scheduled background refresh tries to run during that period, it appears to be deferred—and then remains in that deferred state indefinitely. Even reopening the app or scheduling new refreshes doesn’t recover it. Has anyone else encountered this behavior? Is there a reliable workaround? I’ve seen a few reports suggesting that there may be a regression in scheduleBackgroundRefresh() on watchOS 26, where tasks are never delivered after certain states. Any insights or confirmations would be greatly appreciated. Thank you!

Will App be terminated or suspended when updating to incremental version from app store?

If I create a BGContinuedProcessingTaskRequest, register it, and then "do work" within it appropriately reporting progress, and before my task has finished doing all the work it had to do, its expirationHandler triggers... does the task later try again? Or does it lose the execution opportunity until the app is next re-launched to the foreground? In my testing, I never saw my task execute again once expired (which suggests the latter?). I was able to easily force this expiry by starting my task, backgrounding my app, then launching the iOS Camera App. My example is just using test code inspired from https://developer.apple.com/documentation/backgroundtasks/performing-long-running-tasks-on-ios-and-ipados let request = BGContinuedProcessingTaskRequest(identifier: taskIdentifier, title: "Video Upload", subtitle: "Starting Upload") request.strategy = .queue BGTaskScheduler.shared.register(forTaskWithIdentifier: taskIdentifier, using: nil) { task in guard let task = task as? BGContinuedProcessingTask else { return } print("i am a good task") var wasExpired = false task.expirationHandler = { wasExpired = true } let progress = task.progress progress.totalUnitCount = 100 while !progress.isFinished && !wasExpired { progress.completedUnitCount += 1 let formattedProgress = String(format: "%.2f", progress.fractionCompleted * 100) task.updateTitle(task.title, subtitle: "Completed \(formattedProgress)%") sleep(1) } if progress.isFinished { print ("i was a good task") task.setTaskCompleted(success: true) } else { print("i was not a good task") task.setTaskCompleted(success: false) } } try? BGTaskScheduler.shared.submit(request) Apologies if this is clearly stated somewhere and I'm missing it.

My app is for personal use currently, so distribution won't be a problem. It registers a privileged helper using SMAppService, and I was wondering whether there is a way to customize the authorization dialog that the system presents to the user.

I'm try to monitor all processes by ES client. But I found the process name is different from the Activity Monitor displayed. As shown in the picture below, there are ShareSheetUI(Pages) and ShareSheetUI(Finder) processes in Activity Monitor, but I can only get the same name ShareSheetUI, I thought of many ways to display the name in parentheses, but nothing worked, so there is a way to display the process name like Activity Monitor?

I am writing an app which mainly is used to update data used by other apps on the device. After the user initializes some values in the app, they almost never have to return to it (occasionally to add a "friend"). The app needs to run a background task at least daily, however, without the user's intervention (or even awareness, once they've given permission). My understanding of background refresh tasks is that if the user doesn't activate the app in the foreground periodically, the scheduled background tasks may never run. If this is true, do I want to use a background processing task instead, or is there a better solution (or have I misunderstood entirely)?
