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 > "$SAVE_DIR/$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. <key>Label</key> <string>com.test.logTest</string> <key>ProgramArguments</key> <array> <string>/bin/bash</string> <string>-c</string> /Users/test/Desktop/personal/log_gather/exec/test_ls_save.sh </array> <key>StartInterval</key> <integer>60</integer> <!-- Run every minute --> 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!

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 } }```

Are there any plans to add RBI support (the sending keyword) to the OSAllocatedLock interface? So it could be used with non-sendable objects without surrendering to the unchecked API

I have implemented a XPC server using C APIs. I want to write unit tests for it. I came across the following links that use Swift APIs- Testing and Debugging XPC Code With an Anonymous Listener TN3113 I have tried to write anonymous listener code and the client code in the same file, using C APIs- #include <unistd.h> #include <syslog.h> #include <pthread.h> #include <stdio.h> #include <xpc/xpc.h> #include <xpc/connection.h> #include <CoreFoundation/CoreFoundation.h> static void Anon_Client_Connection_Handler(xpc_connection_t connection, xpc_object_t clientMessage) { const char *description = xpc_copy_description(clientMessage); printf("Event received - %s\n", description); free((void *)description); xpc_type_t type = xpc_get_type(clientMessage); if (type == XPC_TYPE_ERROR) { if (clientMessage == XPC_ERROR_CONNECTION_INVALID) printf("Client_Connection_Handler received invalid connection n"); else if (clientMessage == XPC_ERROR_TERMINATION_IMMINENT) printf("Client_Connection_Handler received termination notice n"); } else { const char *clientMsg = xpc_dictionary_get_string(clientMessage, "message"); printf("Received from client: %s ", clientMsg); } } static void Anon_Listener_Connection_Handler(xpc_connection_t connection) { printf("Anon_Listener_Connection_Handler called, setting up event handler \n"); xpc_connection_set_event_handler(connection, ^(xpc_object_t clientMessage) { printf("Processing the connection! \n"); Anon_Client_Connection_Handler(connection, clientMessage); }); xpc_connection_resume(connection); } int main(int argc, const char *argv[]) { xpc_connection_t anon_listener = xpc_connection_create(NULL, NULL); xpc_connection_set_event_handler(anon_listener, ^(xpc_object_t clientConnection) { printf("Client tried to connect \n"); Anon_Listener_Connection_Handler(clientConnection); }); xpc_connection_resume(anon_listener); printf("\nINFO Anonymous connection resumed"); xpc_object_t anon_endpoint = xpc_endpoint_create(anon_listener); xpc_connection_t clientConnection = xpc_connection_create_from_endpoint(anon_endpoint); xpc_object_t message = xpc_dictionary_create(NULL, NULL, 0); xpc_dictionary_set_string(message, "message", "client's message"); xpc_connection_send_message_with_reply(clientConnection, message, dispatch_get_main_queue(), ^(xpc_object_t event) { printf("\nINFO inside reply"); const char *description = xpc_copy_description(event); printf("\nINFO %s",description); free((void *)description); }); xpc_release(message); xpc_release(anon_listener); printf("\nINFO Releasing listener"); xpc_release(anon_endpoint); printf("\nINFO Releasing endpoint"); // dispatch_main(); return 0; } and this is the output I get INFO Anonymous connection resumed INFO Releasing listener INFO Releasing endpoint I am not able to connect to the client and exchange messages. Where am I going wrong?

I'm working on an XPC server and need to determine the owner of the client process that connects to it. Specifically, I'd like to retrieve details such as the fully qualified user name or other identifying information from the XPC client connection.I'm considering using xpc_connection_get_pid() to get the client’s process ID, but I’m unsure of the best way to map this to the user who owns the process. Is there a recommended API or approach to capture this information securely?

Im using the low-level C xpc api <xpc/xpc.h> and i get this error when I run it: Underlying connection interrupted. I know this error stems from the call to xpc_session_send_message_with_reply_sync(session, message, &reply_err);. I have no previous experience with xpc or dispatch and I find the xpc docs very limited and I also found next to no code examples online. Can somebody take a look at my code and tell me what I did wrong and how to fix it? Thank you in advance.

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?

Hello, aspiring programmer here. I am developing a StepCounter APP, which keeps track of how many steps I have taken and sends to an MQTT server. I am trying to make this happen even while the app is not in focus, but so far I have not been able to get this working. First tried with silent background music, which seemed pretty inconsistent and inpractical, since I usually play youtube videoes while walking, making the app stop with its silent audio. Then tried GPS, which didnt really do anything (could be implementation problem). Has anyone made background processing work for their apps?

I have an XPC server running on macOS and want to perform comprehensive performance and load testing to evaluate its efficiency, responsiveness, and scalability. Specifically, I need to measure factors such as request latency, throughput, and how well it handles concurrent connections under different load conditions. What are the best tools, frameworks, or methodologies for testing an XPC service? Additionally, are there any best practices for simulating real-world usage scenarios and identifying potential bottlenecks?

How can I return the results of a Spotlight query synchronously from a Swift function? I want to return a [String] that contains the items that match the query, one item per array element. I specifically want to find all data for Spotlight items in the /Applications folder that have a kMDItemAppStoreAdamID (if there is a better predicate than kMDItemAppStoreAdamID > 0, please let me know). The following should be the correct query: let query = NSMetadataQuery() query.predicate = NSPredicate(format: "kMDItemAppStoreAdamID > 0") query.searchScopes = ["/Applications"] I would like to do this for code that can run on macOS 10.13+, which precludes using Swift Concurrency. My project already uses the latest PromiseKit, so I assume that the solution should use that. A bonus solution using Swift Concurrency wouldn't hurt as I will probably switch over sometime in the future, but won't be able to switch soon. I have written code that can retrieve the Spotlight data as the [String], but I don't know how to return it synchronously from a function; whatever I tried, the query hangs, presumably because I've called various run loop functions at the wrong places. In case it matters, the app is a macOS command-line app using Swift 5.7 & Swift Argument Parser 1.5.0. The Spotlight data will be output only as text to stdout & stderr, not to any Apple UI elements.

Dear Apple： We are developing an app for file sharing between mobile devices. We want to create an iOS app that can continue sharing files with other devices even when it is running in the background. We are using WLAN channels for file sharing. Could you please advise on which background persistence measures we should use to ensure the iOS app can maintain file transfer when it goes to the background? Thank you.

Hi everyone, I’m Jaswanth. My friends and I are students working on a project where we’ve developed a website and a companion app. Here’s the key functionality: When two users enter a virtual room, one of them is prompted to download a desktop app. The app is built with Python and uses psutil to check for certain running processes. It does not send any data over the internet. It has a GUI that clearly shows the system is being monitored , it’s not hidden or running in the background silently. We want to sign and notarize the app to make sure it runs on macOS without warning users. However, we’re concerned that since the app accesses system process information, it might be flagged as malicious. Before we pay for the Apple Developer Program, we wanted to ask: Will an app like this (which only reads running processes and does not exfiltrate or hide activity) be eligible for notarization? Thanks in advance for any insights. We'd appreciate any clarity before moving forward. Best, Jaswanth

How can you force cancel a task that doesn't need cleanup and doesn't check for cancellation? If this cannot be done, would this be a useful addition to Swift? Here is the situation: The async method doesn't check for cancellation since it is not doing anything repetively (for example in a loop). For example, the method may be doing "try JSONDecoder().decode(Dictionary<String, ...>.self, from: data)" where data is a large amount. The method doesn't need cleanup. I would like the force cancellation to throw an error. I am already handling errors for the async method. My intended situation if that the user request the async method to get some JSON encoded data, but since it is taking longer that they are willing to wait, they would tap a cancellation button that the app provides.

When I search, it's always people trying to do stuff in the background. I want my app to only do stuff when it is active. And this post https://developer.apple.com/forums/thread/685525 seems to have prevented replies from the start. Which means it's just a documentation page and does not belong in the discussion forums at all, because it prevents all discussion.

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

After logging in to the main App, turn on screen recording, then switch to the interface of another App to perform operations. After about ten-odd minutes, when returning to the main App, it was found that the app was forcefully quit by the system, and subsequent operations could not be carried out.
