We have a launch daemon which can check for team identifier and some other signing information of any application on machine and match it with provided information to confirm the validity of the application/binary. We use SecStaticCodeCreateWithPath to read the signing information of the app/binary which works in most cases. However, for some third party daemon processes, the static code creation fails with error "Operation not permitted". We are having difficult time identifying why static code creation would fail specially when our process is running with root privileges. Can you please help us understand in what scenario can this API fail with this error? Can there be any process or rule which can deny creating static code of a process like endpoint security extensions/daemon? We are using default flags in SecStaticCodeCreateWithPath.

Hi ! Would anyone know (if possible) how to create backup files to export and then import from the data recorded by SwiftData? For those who wish, here is a more detailed explanation of my case: I am developing a small management software with customers and events represented by distinct classes. I would like to have an "Export" button to create a file with all the instances of these 2 classes and another "Import" button to replace all the old data with the new ones from a previously exported file. I looked for several solutions but I'm a little lost...

For a given date, there are discrepancies between the step counts obtained from HealthKit and those displayed in the Health app. Is it possible for such discrepancies to occur even if step counts are not manually entered and multiple devices are not being used?

In a project having both an app and a website, the following two website urls are to be handed over to the corresponding app: https://www.example.com/search?plus https://www.example.com/search?query=something In AASA file, this becomes: "components": [ { "/": "/search", "?": { "plus": "", "query": "?*" } } However, finally it does not work for both urls. Only the one with "query" works by hand over to app. For investigation, I have tried this for the problematic link: "components": [ { "/": "/search", "?": "plus" } and this works. How can I get both to work? (note that for the sake of brevity, only a portion of the AASA files are shown)

On iOS 18.x when try to create EASession we get nil, but on iOS 17.x everything works. We have app which use USB cable for connecting external accessories. Scenario is when we have fresh instal, connecting with accessory work fine, EASession is created, streams are opened. When we unplug USB, we close streams, remove any reference to session and accessory, remove accessory delegate. When plug it again, creating EASession is returning nil. Only after restarting iPhone, we can create new EASession with appropriate protocol and accessory. Every next attempt without reseting iPhone is failing. Logs from accessory is following: 00:05:51.811000 : onUSBDeviceFound(pDevice=0xffc818)) iPhone USB device already in the device list w/id=1 -> update status now[21;1H 00:05:51.830000 : setConnectionStatus(status=connected) [devId=1] state updated -> forward[21;1H Capabilities indicate HostMode possibility => role switch is triggered 00:05:52.848000 : updateDIPODeviceConnections() iPhoneUSB w/caps=5 (=CarPlay or HostMode), deviceTag=2 in Device mode -> request role switch[21;1H Role switch seems to be successful 00:05:54.914000 : setSwitching('stable') changed[21;1H 00:05:54.915000 : updateDIPODeviceConnections() iPhoneUSB w/caps=2, id=1, deviceTag=2 and native transport -> request app launch and call connectUSB[21;1H 00:05:54.967000 : ConnectiAP2(05ac:12a8, s/n='00008101000160921E90801E', writeFD='/dev/ffs/ep3', readFD='/dev/ffs/ep4', hostMode){3}[21;1H Native transport should become available but does not (the following line is not present for failed case.

Hi! I've noticed that the IP_RECVIF socket option, i.e.: int y = 1; setsockopt(fd, IPPROTO_IP, IP_RECVIF, &y, sizeof(y)); does not seem to work if the socket is proxied by a NETransparentProxyProvider type network extension: there's no ancillary data in messages received with recvmsg. As soon as I disable the network extension, recvmsg starts returning ancillary data containing the interface name. This seems to break some applications which rely on IP_RECVIF in the presence of a transparent proxy, making it, in fact, not transparent. One such example is Apple's own libresolv, which relies on IP_RECVIF and breaks if there's no ancillary data in the recvmsg result. I don't think that this is the intended behaviour, since IPV6_PKTINFO seems to work fine. I've filed a bug report (FB17586550) about this, however, I would greatly appreciate if someone could point me in the direction of a workaround.

I am seeing a really weird behavior with Live Activities. The Live Activity is always appearing on the simulator. However the Live Activity is only appearing on my physical device when there is no other widget in the widget bundle shown below. @main struct HoerspielWidgetsBundle: WidgetBundle { var body: some Widget { // Uncomment the line below and the Live Activity will no longer appear // UpNextWidget() PlaybackLiveActivity() } } Annotating that var with @WidgetBundle has no effect. There are no logs indicating an error, the function to request a Live Activity does not throw and the status of the activity is active. Both the widget and the Live Activity are working fine otherwise. NSSupportsLiveActivities is set to true in the correct Info.plist file. I am not running any beta software and the physical iPhone is on the newest version (iOS 18.5). Using the template when adding a new target in Xcode, I was able to set up a similar app where the Live Activity works as expected. I am really at a loss here which additional information I should provide or how this issue can be resolved. Thank you for your help.

Hi, our CoreAudio server plugin supports different clock sources. A switch might result in a change of the selectable sample rates (and other settings). On a clock source switch the plugin reconfigures the set of available kAudioStreamPropertyAvailablePhysicalFormats and announces the change via AudioServerPlugInHostInterface::PropertiesChanged(). However at least the Audio MIDI Setup seems to ignore to update it's UI. The changes are first reflected after selecting another device and re-selecting the device of interest. (Latest macOS, M4 macMini) Is this a bug? Or is our CoreAudio server plugin required to indicate the change in the list of available audio formats differently? Thanks!

I tested it on the app I work with and others I use and the notification message is not appearing when using sleep mode. Someone knows something about this, and if it is mapped for correction? Iphone: 13 mini IOS: 18.4.1

I have been polishing an app that connects and communicates between a tvOS app I created and a iPadOS app that I also created. Connection works fantastic! However, for some reason when the user selects the button to open the DevicePicker provided by this API and then selects a iPad device the notification that comes across the the iPad reads, "Connect your Apple TV to "AppName" on this iPhone. Is this a bug or am I missing some configuration in maybe Info.plist or a modifier I need to add the DevicePicker for it to communicate the proper device identification? I have everything setup in both app Info.plist files to connect and work fine, but the notification saying iPhone on an iPad is sadly a small detail I would love to change. So...not sure if I found a bug or if I am missing something.

Hello, I'm encountering a runtime crash when building my visionOS app with Xcode 16.3 for visionOS 2.5. Our existing AppStore/Testflight app is also instantly crashing on visionOS 2.5 when opened but works fine on e.g visionOS 2.4. The app builds successfully but crashes on launch with this symbol lookup error (slightly adjusted because the forum complained regarding sensitive data): Symbol not found: _$sSo22CLLocationCoordinate2DVSE12CoreLocationMc Referenced from: <XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX> /private/var/containers/Bundle/Application/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX/MyApp.app/MyApp.debug.dylib Expected in: <XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX> /usr/lib/swift/libswiftCoreLocation.dylib dyld config: DYLD_LIBRARY_PATH=/usr/lib/system/introspection DYLD_INSERT_LIBRARIES=/usr/lib/libLogRedirect.dylib:/usr/lib/libBacktraceRecording.dylib:/usr/lib/libMainThreadChecker.dylib:/System/Library/PrivateFrameworks/GPUToolsCapture.framework/GPUToolsCapture:/usr/lib/libViewDebuggerSupport.dylib I've already implemented my own Codable conformance for CLLocationCoordinate2D: extension CLLocationCoordinate2D: Codable { // implementation details... } This worked fine on previous visionOS/Xcode versions. Has anyone encountered this issue or found a solution? System details: macOS version: 15.3.2 Xcode version: 16.3 visionOS target: 2.5 Thank you!

We’ve recently encountered an increased rate of purchase errors StoreKit.InvalidRequestError error 1 (https://developer.apple.com/documentation/storekit/invalidrequesterror) specifically on iOS 18.4. We suspect this might be related to the new Advanced Commerce API introduced by Apple, although we haven’t made any changes related to this API in our app. Have you experienced similar issues since the release of iOS 18.4 or when integrating the Advanced Commerce API? Any insights or suggestions would be greatly appreciated. Thanks!

Our app needs to read server settings that are configured in the app's settings. In iPadOS 17.7.7 specifically (iPadOS 17.7.6, iPadOS 18.5, and other versions works fine) one can't retrieve any setting from the settings bundle using: if ([[NSUserDefaults standardUserDefaults] objectForKey:@"setting_hostname"] != nil) serverHostname = [[NSUserDefaults standardUserDefaults] objectForKey:@"setting_hostname"]; Also, when writing a custom value in NSUserDefaults like: [[NSUserDefaults standardUserDefaults] setObject:@"Test" forKey:@"test"]; [[NSUserDefaults standardUserDefaults] synchronize]; NSString* test = [[NSUserDefaults standardUserDefaults] objectForKey:@"test"]; NSLog(@"%@", test); Shows an error in the console: Couldn't write values for keys ( test ) in CFPrefsPlistSource<0x3017ecc60> (Domain: <redacted_bundle_id>, User: kCFPreferencesCurrentUser, ByHost: No, Container: (null), Contents Need Refresh: No): setting these preferences requires user-preference-write or file-write-data sandbox access When closing the app and reopening it, and then reading the value of [[NSUserDefaults standardUserDefaults] objectForKey:@"test"]; returns null

Description: We are developing an iOS app that offers only one auto-renewable subscription. Recently, a user who had not subscribed for over a year purchased the subscription again through our app. However, when they checked Settings > Subscriptions, the new subscription did not appear. Instead, only their past subscription history was visible, and there was no option to cancel the new subscription. We have verified this issue with a screenshot provided by the user. Additionally, we checked our app’s logs and confirmed that StoreKit.product.purchase successfully returned .success, indicating that the purchase was processed correctly. Code used for purchase: let result = try await product? .purchase(options: [ .appAccountToken(uuid) ]) switch result { case .success(let verificationResult): switch verificationResult { case .verified(let transaction): addPurchaseLog("verificationResult.verified.") case .unverified(_, let verificationError): addPurchaseLog("verificationResult.unverified.") case .userCancelled, .pending, .none: addPurchaseLog("verificationResult.userCancelled or .pending or .none") @unknown default: addPurchaseLog("verificationResult.unknown.") } Despite the successful purchase, the new subscription does not appear under the user's active subscriptions. Could this be a bug in StoreKit? If there are any known issues or workarounds, we would appreciate any guidance. Environment: Xcode: 16.2 iOS version: 16.0+

I recently needed to develop an application to obtain the window list, which requires Screen Recording permissions. Apple's official documentation mentions using the two functions CGPreflightScreenCaptureAccess and CGRequestScreenCaptureAccess to request permissions. These functions are stated to be available since version 10.15. However, when I used these two functions on a device running macOS 10.15.7, I encountered the errors shown in the attached screenshot. I used the nm tool to inspect the symbols in the CoreGraphics.framework and found that these two functions were not present. Could you help me understand why this is happening?

For our outdoor power supply company that builds public WiFi networks at camping sites, we want to implement the following features in our app: Scan surrounding WiFi networks When detecting specific public WiFi SSIDs, provide users with corresponding passwords Automatically connect to those WiFi networks Regarding the NEHotspotHelper API permission application, when I clicked on https://developer.apple.com/contact/request/network-extension, it redirected me to https://developer.apple.com/unauthorized/. I'm not sure where to properly apply for this permission now.

I have implemented a Live Activity that includes two buttons. Currently, both buttons utilize deep links to open the main application, where I then detect the URL to perform the corresponding action. My primary question is: Is it possible to update a button's title and/or color within a Live Activity without requiring the main application to open?

Hi All, I am looking for a terminal command to get the exact same output as the file count you recieve when using Get Info in finder. The closest i can get is using the find command with flags: find 'path/to/folder' -not -path '*/\.*' -and -not -path '*\.key/*' -and -not -path '*\.numbers/*' -and -not -path '*\.pages/*' -and -not -path '*__MACOSX/*' -and -not -path '*\.pdf/*' -and -not -path '*\.app/*' -and -not -path '*\.rtfd/*' | wc -l I will be searching on an external volume that sometimes produces keynote save files that finder sometimes sees as a package and sometimes sees as a folder. If a folder finder counts the items contained if a package it doesn't, I need the command or script to mimic this behaviour. In the example of the screenshot get info on the top folder produces a count of 14 and the find command produces a count of 23. There are also other behaviours that differ the file count between them but i'm not sure what causes them. Any help on a solution it being a command or script would be much apreciated. Thanks, James

Is there a public method to know when an APNS has appeared on the screen? wrapping up a very high end photogrammetry app, using the front facing camera and screen illumination- incoming notifications completely throw off the math. Ideally, it would be great to turn on Do Not Disturb for the short process, but we’d settle for just the detection of the notification banner. also: extra credit - programattically adjusting Auto Dimming, and True Tone would be lovely too.

Hi everyone, I'm developing a visionOS app that allows users to download large video files (similar to a movie download experience, with each file being around 10 GB). I've successfully implemented the core video download functionality using URLSession, and everything works as expected while the app is active. Now, I’m looking to support background downloading. Specifically, I want users to be able to start a download and then leave the app (e.g., switch apps or return to the home screen) while the download continues in the background. Additionally, I’d like to confirm a specific scenario: If the user starts a download, then removes the headset (keeping the device turned on and connected to power), will the download continue in the background? Or does visionOS suspend the app or downloads in this case? I’m considering using a background URLSessionConfiguration (as done in iOS/macOS) to enable this behavior, but I’m not sure if it behaves the same way on visionOS or if there are special limitations or best practices when handling large downloads on this platform. Any insights or official guidance would be greatly appreciated! Thanks!
