I have several processes maintaining NSXPConnection to an XPC service. The connections are bi-directional. Each side service and clients) of the connection exports an object, and an XPCInterface. The @protocols are different - to the service, and from the service to clients. So long as all the "clients" fully implement their "call-back" @protocol, there's no problem. All works fine. However - If a client does NOT implement a method in the "call back protocol", or completely neglects to export an object, or interface - and the service attempts to call back using the nonexistent method -- the XPC connection invalidates immediately. So far - expected behaviour. However, if I want the service to behave to the client a little like a "delegate" style -- and check first whether the client "respondsToSelector" or even - supports an interface BEFORE calling it, then this doesn't work. When my XPC service tries the following on a client connection: if (xpcConnection.remoteObjectInterface == nil) os_log_error(myXPCLog, "client has no remote interface); the condition is never met - i.e. the "remoteObjectInterface is never nil even when the client does NOT configure its NSXPCConnection with any incoming NSXPCInterface, and does not set an "exportedObject" Furthermore, the next check: if ([proxy respondsToSelector:@selector(downloadFiltersForCustomer:withReply:)]) { } will not only fail - but will drop the connection. The client side gets the invalidation with the following error: <NSXPCConnection: 0x600000b20000> connection to service with pid 2477 named com.proofpoint.ecd: received an undecodable message for proxy 1 (no exported object to receive message). Dropping message. I guess the "undecidable message" is the respondsToSelector - because the code doesn't get to attempt anything else afterwards, the connection drops. Is there a way to do this check "quietly", or suffering only "interruption", but without losing the connection,

I am trying to migrate a WatchConnectivity App to Swift6 and I found an Issue with my replyHandler callback for sendMessageData. I am wrapping sendMessageData in withCheckedThrowingContinuation, so that I can await the response of the reply. I then update a Main Actor ObservableObject that keeps track of the count of connections that have not replied yet, before returning the data using continuation.resume. ... @preconcurrency import WatchConnectivity actor ConnectivityManager: NSObject, WCSessionDelegate { private var session: WCSession = .default private let connectivityMetaInfoManager: ConnectivityMetaInfoManager ... private func sendMessageData(_ data: Data) async throws -> Data? { Logger.shared.debug("called on Thread \(Thread.current)") await connectivityMetaInfoManager.increaseOpenSendConnectionsCount() return try await withCheckedThrowingContinuation({ continuation in self.session.sendMessageData( data, replyHandler: { data in Task { await self.connectivityMetaInfoManager .decreaseOpenSendConnectionsCount() } continuation.resume(returning: data) }, errorHandler: { (error) in Task { await self.connectivityMetaInfoManager .decreaseOpenSendConnectionsCount() } continuation.resume(throwing: error) } ) }) } Calling sendMessageData somehow causing the app to crash and display the debug message: Incorrect actor executor assumption. The code runs on swift 5 with SWIFT_STRICT_CONCURRENCY = complete. However when I switch to swift 6 the code crashes. I rebuilt a simple version of the App. Adding bit by bit until I was able to cause the crash. See Broken App Awaiting sendMessageData and wrapping it in a task and adding the @Sendable attribute to continuation, solve the crash. See Fixed App But I do not understand why yet. Is this intended behaviour? Should the compiler warn you about this? Is it a WatchConnectivity issue? I initially posted on forums.swift.org, but was told to repost here.

It looks like ExtensionKit (and ExtensionFoundation) is fully available on iOS 26 but there is no mention about this in WWDC. From my testing, it seems as of beta 1, ExtensionKit allows the app from one dev team to launch extension provided by another dev team. Before we start building on this, can someone from Apple help confirm this is the intentional behavior and not just beta 1 thing?

We are currently developing a VoIP application that supports Local Push extention. I would like to ask for your advice on how the extension works when the iPhone goes into sleep mode. Our App are using GCD (Grand Central Dispatch) to perform periodic processing within the extension, creating a cycle by it. [sample of an our source] class LocalPushProvider: NEAppPushProvider { let activeQueue: DispatchQueue = DispatchQueue(label: "com.myapp.LocalPushProvider.ActiveQueue", autoreleaseFrequency: .workItem) var activeSchecule: Cancellable? override func start(completionHandler: @escaping (Error?) -&gt; Void) { : self.activeSchecule = self.activeQueue.schedule( after: .init(.now() + .seconds(10)), // start schedule after 10sec interval: .seconds(10) // interval 10sec ) { self.activeTimerProc() } completionHandler(nil) } } However In this App that we are confirming that when the iPhone goes into sleep mode, self.activeTimerProc() is not called at 10-second intervals, but is significantly delayed (approximately 30 to 180 seconds). What factors could be causing the timer processing using GCD not to be executed at the specified interval when the iPhone is in sleep mode? Also, please let us know if there are any implementation errors or points to note. I apologize for bothering you during your busy schedule, but I would appreciate your response.

Hi Team, We intend to create a custom serial dispatch queue targetting a global queue. let serialQueue = DispatchQueue(label: "corecomm.tallyworld.serial", target: DispatchQueue.global(qos: .default)) The documentation for DispatchQueue init does not show any minimum OS versions. BUT DispatchSerialQueue init does show iOS 17.0+ iPadOS 17.0+ Mac Catalyst macOS 14.0+ tvOS 17.0+ visionOS watchOS 10.0+. Does that mean - I will not be able to create a custom serial dispatch queue below iOS 17?

I’m trying to enable Background Modes (specifically for audio, background fetch, remote notifications) in my iOS SwiftUI app, but I’m getting this error: Provisioning profile “iOS Team Provisioning Profile: [my app]” doesn’t include the UIBackgroundModes entitlement. On the developer website when I make the provision profile It doesnt give me the option to allow background modes. I added it to the sign in capabilities seccion in X code and matched the bundle ID to the provision profile and certificate etc but it still runs this error because the provision profile doesnt have the entitlements..

We are experiencing a crash in our application that only occurs on devices running iOS beta 26. It looks like a Beta problem. The crash appears to be caused by an excessive number of open File Descriptors. We identified this after noticing a series of crashes in different parts of the code each time the app was launched. Sometimes it would crash right at the beginning, when trying to load the Firebase plist file. That’s when we noticed a log message saying “too many open files,” and upon further investigation, we found that an excessive number of File Descriptors were open in our app, right after the didFinishLaunching method of the AppDelegate. We used the native Darwin library to log information about the FDs and collected the following: func logFDs() { var rlim = rlimit() if getrlimit(RLIMIT_NOFILE, &rlim) == 0 { print("FD LIMIT: soft: \(rlim.rlim_cur), hard: \(rlim.rlim_max)") } // Count open FDs before Firebase let openFDsBefore = countOpenFileDescriptors() print("Open file descriptors BEFORE Firebase.configure(): \(openFDsBefore)") } private func countOpenFileDescriptors() -> Int { var count = 0 let maxFD = getdtablesize() for fd in 0..<maxFD { if fcntl(fd, F_GETFD) != -1 { count += 1 } } return count } With this code, we obtained the following data: On a device with iOS 26 Beta 1, 2, or 3: FD LIMIT: soft: 256, hard: 9223372036854775807 Open file descriptors BEFORE Firebase.configure(): 256 On a device with iOS 18: FD LIMIT: soft: 256, hard: 9223372036854775807 Open file descriptors BEFORE Firebase.configure(): 57 In the case of the device running iOS 26 beta, the app crashes when executing Firebase.configure() because it cannot open the plist file, even though it can be found at the correct path — meaning the OS locates it. To confirm this was indeed the issue, we used the following code to close FDs before proceeding with Firebase configuration. By placing a breakpoint just before Firebase.configure() and running the following LLDB command: expr -l c -- for (int fd = 180; fd < 256; fd++) { (int)close(fd); } This released the FDs, allowing Firebase to proceed with its configuration as expected. However, the app would later crash again after hitting the soft limit of file descriptors once more. Digging deeper, we used this code to try to identify which FDs were being opened and causing the soft limit to be exceeded: func checkFDPath() { var r = rlimit() if getrlimit(RLIMIT_NOFILE, &r) == 0 { print("FD LIMIT: soft: \(r.rlim_cur), hard: \(r.rlim_max)") for fd in 0..<Int32(r.rlim_cur) { var path = [CChar](repeating: 0, count: Int(PATH_MAX)) if fcntl(fd, F_GETPATH, &path) != -1 { print(String(cString: path)) } } } } We ran this command at the very beginning of the didFinishLaunching method in the AppDelegate. On iOS 26, the log repeatedly showed Cryptexes creating a massive number of FDs, such as: /dev/null /dev/ttys000 /dev/ttys000 /private/var/mobile/Containers/Data/Application/AEE414F2-7D6F-44DF-A6D9-92EDD1D2B014/Library/Application Support/DTX_8.191.1.1003.sqlite /private/var/mobile/Containers/Data/Application/AEE414F2-7D6F-44DF-A6D9-92EDD1D2B014/Library/Caches/KSCrash/MyAppScheme/Data/ConsoleLog.txt /private/var/mobile/Containers/Data/Application/AEE414F2-7D6F-44DF-A6D9-92EDD1D2B014/Library/HTTPStorages/mybundleId/httpstorages.sqlite /private/var/mobile/Containers/Data/Application/AEE414F2-7D6F-44DF-A6D9-92EDD1D2B014/Library/HTTPStorages/mybundleId/httpstorages.sqlite-wal /private/var/mobile/Containers/Data/Application/AEE414F2-7D6F-44DF-A6D9-92EDD1D2B014/Library/HTTPStorages/mybundleId/httpstorages.sqlite-shm /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.01 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.11 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.12 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.13 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.14 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.15 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.16 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.17 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.18 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.19 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.20 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.21 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.22 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.23 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.24 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.25 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.26 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.29 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.30 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.31 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.32 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.36 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.37 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.38 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.39 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.40 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e … This repeats itself a lot of times. … /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.36 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.37 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.38 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.39 /private/preboot/Cryptexes/OS/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e.40

We've seen a recent increase in background terminations: blue - System Pressure orange - Task Timeout I'm trying to understand the increase in system-pressure terminations, since there's no corresponding increase in memory at suspension. Are there other system resources for which iOS will terminate an app?

Hi there, First thanks for all the work on BGContinuedProcessingTask! It looks really promising. I have a question / issue around the behavior when a BGContinuedProcessingTask expires. Here is my setup. I have an app who's responsible for uploading large files in the field (AKA wifi is not expected) For a given file, it can likely fail due to network conditions I'm using Multipart upload though so I can retry a file to pick up where it left off. I use one taskIdentifier per file, and when the file fails, I can retry the task and have it continue where it left off (I am reusing the taskIdentifier here for retries, let me know if I shouldn't be doing that) Here is the behavior I am seeing I start an upload, it seems to be uploading normally I turn on airplane mode to simulate expiration of the task the task fails as expected after ~30 seconds, and I see the failure in my home screen. I have callbacks in the task to put my app in the proper state on expiration / failure I turn back on airplane mode and I retry the task, the way I do this is I do NOT re-register, I simply re-submit the task with the same TaskIdentifier. What I would have expected is that the failure task is REPLACED with the new task and new progress. Instead what I see is TWO ContinuedBackgroundProcessingTasks, one in the failure state and one in progress. My question is How can I make retries reuse the same task notification item? OR if that's not possible, how do I programmatically clear the task failure? I've tried cancelTask but that doesn't seem to clear it.

I have an app that uses background audio recording. From what others say, I have enabled the audio background mode to keep the audio session active, and this worked. But when submitting the app to the app store, the app was rejected because the audio background mode is only supposed to be used for audio playback. How do I create this background mode while following Apple's guidelines?

Hello, My team has developed a DNS proxy for macOS. We have this set up with a system extension that interacts with the OS, and an always-running daemon that does all the heavy lifting. Communication between the two is DNS request and response packet traffic. With this architecture what are best practices for how the system extension communicates with a daemon? We tried making the daemon a socket server, but the system extension could not connect to it. We tried using XPC but it did not work and we could not understand the errors that were returned. So what is the best way to do this sort of thing?

I am trying to create an app bundle with an xpc service. The main app creates a keychain item, and attempts to share (keychain access groups) with the xpc service it includes in its bundle. However, the xpc service always encounters a 'user interaction not allowed' error regardless of how I create the keychain item. kSecAttrAccessiblei is set to kSecAttrAccessibleWhenUnlockedThisDeviceOnly, the keychain access group is set for both the main app and the xpc service and in the provisioning profile. I've tried signing and notarizing. Is it ever possible for an xpc service to access the keychain? This all on macos 15.5.

Hi, I'm working on an application on MacOS. It contains a port-forward feature on TCP protocol. This application has no UI, but a local HTTP server where user can access to configure this application. I found that my application always exit for unknown purpose after running in backgruond for minutes. I think this is about MacOS's background process controlling. Source codes and PKG installers are here: https://github.com/burningtnt/Terracotta/actions/runs/16494390417

I've been experimenting with the new low-level Swift API for XPC (XPCSession and XPCListener). The ability to send and receive Codable messages is an appealing alternative to making an @objc protocol in order to use NSXPCConnection from Swift — I can easily create an enum type whose cases map onto the protocol's methods. But our current XPC code validates the incoming connection using techniques similar to those described in Quinn's "Apple Recommended" response to the "Validating Signature Of XPC Process" thread. I haven't been able to determine how to do this with XPCListener; neither the documentation nor the Swift interface have yielded any insight. The Creating XPC Services article suggests using Xcode's XPC Service template, which contains this code: let listener = try XPCListener(service: serviceName) { request in request.accept { message in performCalculation(with: message) } } The apparent intent is to inspect the incoming request and decide whether to accept it or reject it, but there aren't any properties on IncomingSessionRequest that would allow the service to make that decision. Ideally, there would be a way to evaluate a code signing requirement, or at least obtain the audit token of the requesting process. (I did notice that a function xpc_listener_set_peer_code_signing_requirement was added in macOS 14.4, but it takes an xpc_listener_t argument and I can't tell whether XPCListener is bridged to that type.) Am I missing something obvious, or is there a gap in the functionality of XPCListener and IncomingSessionRequest?

I'm a developer using Lazarus Pascal, so converting ObjC and Swift comes with its challenges. I'm trying to figure how to properly use SMAppService to add my application as a login item for the App Store. I have learned that the old method (&lt; macOS 13) uses a helper tool, included in the app bundle, which calls the now deprecated SMLoginItemSetEnabled. Now this is already quite a pain to deal with if you're not using XCode, not to mention converting the headers being rather complicated when you're not experienced with doing this. The "new" method (as of macOS 13) is using SMAppService. Can anyone explain how to use this? The documentation (for me anyway) is a not very clear about that and neither are examples that can be found all over the Internet. My main question is: Can I now use the SMAppService functions to add/remove a login item straight in my application, or is a helper tool still required?

The following code worked as expected on iOS 26 RC, but it no longer works on the official release of iOS 26. Is there something I need to change in order to make it work on the official version?

I'm troubleshooting a crash I do not understand. I have a queue called DataQueue which never has anything dispatched to it - it's the sample buffer delegate of an AVCaptureVideoDataOutput.

Started a new X-Code Project after updating to 26.0.1 and realized that I get an error when trying to mark a class as ObservableObject => "Class XYZ does not conform to Protocol 'ObservableObject'. Strange behaviour, because at old projects the code is working even though the build options are the same and other settings like iOS version in Target are the same. There must be something chaged under the hood of XCode? I have to import Combine now, before I could write my class, e.g. CoreData Datamanager: ObservableObject only using CoreData.

I have an app for macOS that is built using Mac Catalyst. I need to perform some background processing. I'm using BGProcessingTaskRequest to schedule the request. I have also integrated CKSyncEngine so I need that to be able to perform its normal background processing. On iOS, when the user leaves the app, I can see a log message that the request was scheduled and a bit later I see log messages coming from the actual background task code. On macOS I ran the app from Xcode. I then quit the app (Cmd-q). I can see the log message that the request was scheduled. But the actual task is never run. In my test, I ran my app on a MacBook Pro running macOS 26.0. When I quit the app, I checked the log file in the app sandbox and saw the message that the task was scheduled. About 20 minutes later I closed the lid on the MacBook Pro for the night. I did not power down, it just went to sleep. Roughly 10 hours later I opened the lid on the MacBook Pro, logged in, and checked the log file. It had not been updated since quitting the app. I should also mention that the laptop was not plugged in at all during this period. My question is, does a Mac Catalyst app support background processing after the user quits the app? If so, how is it enabled? The documentation for BGProcessingTaskRequest and BGProcessingTask show they are supported under Mac Catalyst, but I couldn't find any documentation in the Background Tasks section that mentioned anything specific to setup for Mac Catalyst. Running the Settings app and going to General -> Login Items & Extension, I do not see my app under the App Background Activity section. Does it need to be listed there? If so, what steps are needed to get it there? If this is all documented somewhere, I'd appreciate a link since I was not able to find anything specific to making this work under Mac Catalyst.

Hello, I'm experiencing an issue with my app where it's being terminated by the system with a watchdog violation during back-to-back messaging operations. I've analyzed the crash logs but would appreciate additional insights on optimizing my approach. I'd appreciate any insights on how to resolve this problem. Crash Details: Exception Type: EXC_CRASH (SIGKILL) Termination Reason: FRONTBOARD with code 0x8BADF00D Error: "scene-update watchdog transgression: app exhausted real time allowance of 10.00 seconds" Reproduction Steps: User A initiates back-to-back messages to other User User A's UI becomes unresponsive and eventually the app crashes.
