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!

While playing around with AppShortcuts I've been encountering some problems around getting the invocation phrase detected and/or the parameter get recognized after invocation phrase via Siri. I've found some solutions or explanations here in other posts (Siri not recognizing the parameter in the phrase & Inform iOS about AppShortcutsProvider), but I still have one issue and it's about consistency. For context, I've defined the parameter to be an AppEntity with it's respective query conforming to the EntityStringQuery Protocol in order to be able to fetch entities with the string given by Siri struct AnIntent: AppIntent { // other parts hidden for clarity @Parameter var entity: ModelEntity } For an invocation phrase akin to "Do something with in ", if the user uses the phrase with a entity previously donated via suggestedEntities() the AppShortcut get executed without problems. If the user uses a phrase with no parameter, like "do something with ", if the user gets asked to input the missing parameter and inputs one, it may or may not get recognized and be asked to input a parameter again, like in a loop. This happens even if the parameter given is one that was donated. I've found that when this happens the entities(matching string: String) function in the EntityQuery doesn't get called. The input can be of one word or sometimes two and it will not be called. So in other words entities(matching string: String) does not get called on every user parameter input Is this behavior correct? Do parameters have some restrictions on length or anything? Does Siri shows the user suggested entities when asked for entity input? It doesn't on my end. Additional question related to AppShortcuts: On AppShortcut definition, where the summary inside the parameter presentation is used? I see that it was defined in the AppIntentsSampleApp for the GetTrailInfo Intent but didn't find where it was used

Hello guys, I have been trying to advertise in the background but I can’t seem to make it work. In my case, I want if a device is acting as a peripheral and the app goes to the background it still can be discoverable and be able to write/read to/from it by the central. I have added the background mode “Acts as a Bluetooth accessory”. When will willRestoreState be called? What should I do in willRestoreState? Will it always be discoverable or have some limitations? Should I stop advertising at any point? How should I clean up after the view is dismissed? Must the peripheral manager be initialized in the AppDelegate? and if so, will it always be advertising even if I don't want it to? What are the battery concerns? Also, I have encountered an issue that my iPhone device can discover an Android device but not the opposite. What could be the problem of this? Thank you. Best regards

I am creating an AppIntent to be used with Shortcuts and I would like to return a flexible dictionary of values with nested structures. As far as I understand the custom AppEntity only uses the displayRepresentation to store a title and subtitle which are LocalizedStringResource. types. Although I can convert my dictionary into a string I found no way in shortcuts to be able to retrieve the original structure of it and inspect individual elements like in subsequent actions. Is there a way to do this? Thank you in advance Nick Karanatsios

My CoreSpotlight extension seems to exceed the 6 MB memory limit. What’s the best way to debug this? I've tried to attach the debugger on the Simulator but the extension seems to be never launched when I trigger the reindex from Developer settings. Is this supposed to work? On device, I am able to attach the debugger. However, I can neither transfer the debug session to Instruments, nor display the memory graph. So I've no idea how the memory is used. Any recommendations how to move forward? Is there a way to temporarily disable the memory limit since even with LLDB attached, the extension is killed.

When an iOS device is connected to a Bluetooth accessory that utilizes the Hands-Free Profile (HFP), we are encountering an incorrect audio routing behavior specifically for system notification tones. Accessory Connected: The iOS device is successfully connected to a Bluetooth accessory (specifically, a WM500 device) using the HFP profile for voice communication. Voice Audio: Audio streams related to phone calls or voice communication (using the HFP/SCO link) are correctly routed to the WM500. Notification Tones Issue: System notification tones, which are played using the tonetype.systemsounds API, are not being routed to the connected HFP accessory (WM500). Instead, they are incorrectly played through the iOS device's built-in speaker. This causes a poor user experience, as critical application alerts and system notifications are missed when the user is relying on the connected HFP accessory for all audio output.

But iOS does not provide an external API (like Android's startBluetoothSco) to explicitly force the establishment of an SCO connection for notification tones. Is there any other approach to establish SCO connection in iOS to route notification tones through WM500

Is there any way of creating complete Shortcuts automations and bundling them with my app? Specifically, I would like the user to be able to Take a photo and open it with my app Or take a screenshot and open it with my app Of course I could offer a Share extension, but going through the Share menu and selecting my app there is time consuming for the user. I would like the user to be able to configure his or her action button such that it takes a new picture and opens it with my app right away. I can, of course, offer the respective App Shortcuts and let the user combine them into a pipeline with the Take Screenshot or Take Photo system actions. However, only power users would do this. Hence, I would like to bundle this complete pipeline with my app, such that the user just has to assign his/her Action Button to this pipeline if he/she wants to use this feature. How to go about this? I was thinking of exporting the shortcut into a file, bundling it with the app as a resource, and offering it via a Share action for the user to install it, or by sharing it on iCloud and adding the iCloud link to the UI of my app. What is the recommended approach?

I have a standalone Apple Watch app that uses Bluetooth with the bluetooth-central background mode. It seems that in watchOS 26.2, once the system terminates the BLE connection after background allowance is exceeded, the app never regains background BLE capability, even after the user returns to the foreground and interacts with it. This contradicts the documentation and the WWDC22 “Get timely alerts from Bluetooth devices on watchOS” session, which state that background BLE connectivity should be restored when the user brings the app back to the foreground. Does anyone have any insight into this behavior?

Hi there, Does anyone know how to modify this Image compressor Shortcut https://www.icloud.com/shortcuts/e13d8013598f4f33830386a956a163dd so that the image it creates has the original file name + “-pressed”? Eg “Image_123” becomes “Image_123-pressed” I know of the action ‘Rename file’ but can’t make it work. Any help much appreciated:)

I regularly receive emails from my customers asking why my app, which copies files from a source folder to a destination folder, gives an error during the copy operation, usually when some kind of NAS is involved. I then ask if copying the same file works in the Finder and they usually say yes. Then it’s up to me to contact the NAS vendor and ask why their NAS doesn’t work correctly with the copyfile function which my app uses to copy files, and provide them with a sample Xcode project that reproduces the issue. It would be so much easier for me, and probably other developers as well, if my customers could test their NAS with the Finder, then if it doesn’t work, contact their NAS vendor and solve the issue, or if it works, rest assured that file copies will work for any other app that uses the same API as the Finder. I could spend my time doing much more productive and interesting work rather than checking why every other NAS doesn’t work with my app which, after all, uses the most basic file copy mechanism available on macOS. Is there any chance that in the future (hopefully sooner than later) there will be an API to copy files like the Finder with progress information, or is there a reason why this won't ever be possible?

Currently, we are developing an all-in-one DualSense utility for macOS. We are exploring how to integrate shortcuts into our app. Our vision is to have the user use the native Shortcuts app to choose the controller buttons that should trigger the shortcut action, such as opening Steam, turning on audio haptics, and more. As we explore this approach, we want to see whether we need to build the UI in our app to set the triggers or can we do this inside of Shortcuts? Can button presses recorded by our app trigger shortcuts? Can those button inputs be customized inside of Shortcuts or should we develop it into our app? And if we have it in our app, can our app see, select, and trigger shortcuts?

I'm new to swift and iOS development. I'm trying to create a file provider extension for my app. I have able to use createItem, modifyItem, fetchContents functions. But when I try to add a GarageBand file or a big size mp3 file(18 Mb) I can see multiple upload is happening. I checked the FruitBasket project where they are doing chunked upload when file size is more than 100 Mb. How do I fix this to only one upload? I'm getting suggestions like I have to do debounce upload but that seems not a proper solutions.

Is there a way using a shell script or AppleScript to add a custom icon to a desktop shortcut? I can create the shortcut in a script but I have to manually change the icon. thx much

When establishing a Bluetooth connection and subscribing to feature values, the log shows a subscription failure with the error: did fail to update notification state: The handle is invalid.

I'm building an automated wallpaper updater that fetches images from an API and sets them as desktop wallpaper on macOS Tahoe. The automation uses AppleScript combined with database manipulation to ensure wallpaper applies to all spaces. Current implementation (via Apple Shortcuts): wallpaper_path="$1" osascript -e "tell application \"System Events\" to tell every desktop to set picture to POSIX file \"$wallpaper_path\"" sqlite3 ~/Library/Application\ Support/Dock/desktoppicture.db "UPDATE data SET space=NULL WHERE space IS NOT NULL;" 2>/dev/null killall -HUP Dock Issue First run: Works perfectly - sets wallpaper on all spaces/desktops, "Show on all spaces" is ON After first run: "Show on all spaces" automatically toggles OFF in System Settings Second run onwards: New wallpaper only updates on the active space, inactive spaces show old wallpaper Expected: "Show on all spaces" should remain ON after programmatic wallpaper changes Actual: System Settings automatically disables it, breaking subsequent updates Tested workarounds (all failed): UPDATE data SET space=NULL to clear per-space entries Using every desktop instead of current desktop in AppleScript killall Dock vs killall -HUP Dock vs killall -USR1 Dock Clearing space_id entries from pictures table Running DELETE FROM pictures WHERE space_id IS NOT NULL before setting The database manipulation doesn't prevent macOS from automatically creating per-space entries and disabling the "Show on all spaces" toggle. Question: Is there a way to programmatically set wallpaper while preserving the "Show on all spaces" setting on macOS Tahoe? Environment: macOS: Tahoe (latest) Architecture: Apple Silicon Use case: Daily automated wallpaper updates via Shortcuts

macOS 14.8.2 is released (xnu-10063.141.1.707.11~1), no KDK for it either, or any other 14.8.x (14.8, 14.8.1, 14.8.2) macOS. Last KDK for macOS 14.x was released in July, for 14.7.7. Is there any explanation from Apple why?

I use the code below to rename a file, it works ok, but then the system calls accommodatePresentedItemDeletion(completionHandler:) on a NSFilePresenter that presents the file, immediately after the call to presentedItemDidMove(to:) What am I doing wrong? NSFileCoordinator().coordinate(writingItemAt: oldURL, options: .forMoving, writingItemAt: newURL, options: [], error: &error) { (actualURL1, actualURL2) in do { coordinator.item(at: actualURL1, willMoveTo: actualURL2) try FileManager().moveItem(at: actualURL1, to: actualURL2) coordinator.item(at: actualURL1, didMoveTo: actualURL2) } catch {...} }

I've got a streaming Radio app that loads an HLS stream into an AVAudioPlayer. I've set up an Intents extension that notifies SiriKit that my app must handle the INPlayMediaIntent in app, and, I'm able to successfully initiate the stream playing from my phone using the string "Play ". My intent handler in app looks like this: completionHandler(INPlayMediaIntentResponse(code: .success, userActivity: nil)) DispatchQueue.main.async { AudioPlayerService.shared.play() } The Audio Player service, in its init, does the following: try AVAudioSession.sharedInstance().setCategory( .playback, mode: .default, policy: .longFormAudio ) Additionally, in my Info.plist, I have the AirPlay optimization policy set to Long Form Audio. Having said all that, when I try to route my app to play "on a given HomePod speaker" ("play on ") the speaker routing instructions are never followed. I've looked and not been able to find where I might be able to instruct my app to follow the correct path here. I was assuming I could not trigger this behavior manually, as I believe I don't really have any control over AirPlay routing. Is there any guidance for working with SiriKit to do the right thing with regards to audio routing?
