Hello,
In production, a large number of users experience outgoing call reporting fails with the following error:
com.apple.CallKit.error.requesttransaction Code=2
The iOS version doesn't matter, errors are present in v15-26
Details
My CXProvider held as a global singleton, so it’s unlikely to be deinited.
There is no explicit call to CXProvider.invalidate() in the app.
If I manually invalidate the CXProvider, I observe the expected failure when trying to create an outgoing call (com.apple.CallKit.error.requesttransaction error 2).
However, If I recreate the CXProvider after the error, outgoing calls are reported correctly.
Many users trigger the providerDidReset delegate method (CXProviderDelegate) before this error.
According to the documentation, providerDidReset can be called by the system, and we are supposed to end all active calls, but the documentation doesn't suggest recreating the CXProvider.
Question
Should I recreate CXProvider after providerDidReset and forget about that, or could this error be caused by something else?

Hi, we are developing a screen time management app. The app locks the device after it was used for specified amount of time.
After updating to iOS 26.2, we noticed a huge issue: the events started to fire (reach the threshold) in the DeviceActivityMonitorExtension prematurely, almost immediately after scheduling. The only solution we've found is to delete the app and reboot the device, but the effect is not lasting long and this does not always help.
Before updating to iOS 26, events also used to sometimes fire prematurely, but rescheduling the event often helped. Now the rescheduling happens almost every second and the events keep reaching the threshold prematurely.
Can you suggest any workarounds for this issue?
I decode an object with NSKeyedArchiver (SecureCoding):
typealias BoolArray = Array<Array<Bool>>
let val = decoder.decodeObject(of: NSArray.self, forKey: someKey) as? BoolArray
I get the following log:
*** -[NSKeyedUnarchiver validateAllowedClass:forKey:] allowed unarchiving safe plist type ''NSNumber' (0x204cdbeb8) [/System/Library/Frameworks/Foundation.framework]' for key 'NS.objects', even though it was not explicitly included in the client allowed classes set: '{(
"'NSArray' (0x204cd5598) [/System/Library/Frameworks/CoreFoundation.framework]"
)}'. This will be disallowed in the future.
I changed by adding NSNumber.self in the list :
let val = decoder.decodeObject(of: [NSArray.self, NSNumber.self], forKey: someKey) as? BoolArray
No more warning in log.
Is there a reason for this ?
I'm using the new AlarmKit framework to schedule and trigger alarms in my Swift app in iOS 26 beta 4 (23A5297i).
I'm trying to customize the alarm sound using a sound file embedded in the app bundle or by referencing known system tones.
Problem:
No matter what I pass to .named("sound-2"), whether a file bundle url, .named("sound-2.caf"), tried .mp3, .caf & .aiff, or a known iOS system sound like .named("Radar") ("Chimes", etc.), the alarm always plays the default system alert tone. There's no error or warning, but the custom or specified sound is silently ignored.
sound: .named("sound-2")
Question:
What is the correct method or approach to play custom sound / music when Alarm Triggers?
What .named("...") expects file name, file Path URL or System sound name?
Is there any specific audio file length accepted or specific format?
Challenge:
The alarm functionality feels incomplete without support for custom sounds. A single default alert tone is often not sufficient to wake up users effectively. Hope it will be fixed in the next iOS updates.

When I launch the Quick Look Preview Extension target in Xcode, an app called Quick Look Simulator opens with an almost empty window:
Online I read that the Terminal command qlmanage allows to test Quick Look plugins (which I think were an older format for creating Quick Look extensions), but running
qlmanage -p /path/to/previewed/file -c public.text -g /path/to/QuickLookPreviewExtension.appex
(where QuickLookPreviewExtension.appex is generated by the Xcode build and is located in the DerivedData folder) gives an error
Can't get generator at QuickLookPreviewExtension.appex
How can I debug a Quick Look Preview Extension?
How to programmatically check if ApplicationToken or ActivityCategoryToken is expired in FamilyActivityPicker?
I'm building a Screen Time-based parental control app using FamilyControls and ManagedSettings. We use FamilyActivityPicker to allow the user to select apps and categories to restrict, and we apply the shield using:
store.shield.applications = .specific(selection.applicationTokens)
store.shield.applicationCategories = .specific(selection.categoryTokens)
Sometimes, we observe that the shield silently fails to apply — no error is thrown, but the restrictions aren't enforced. I suspect this may be due to expired or invalid tokens, possibly if the app was removed or the selection became stale.
My Questions:
Can ApplicationToken or ActivityCategoryToken expire or become invalid over time?
If yes, is there a supported or recommended way to detect whether a token is still valid before applying it to the shield?
Is comparing the current shield values (store.shield.applications and store.shield.applicationCategories) after applying them a reliable validation method?
What's the best practice to handle expired tokens (e.g. re-prompt the FamilyActivityPicker, or show a fallback)?
What Is the Expiration Duration of Tokens from FamilyActivityPicker?
Any guidance or insight from the Screen Time/FamilyControls team would be greatly appreciated!
Thank you!
Is there a way to enumerate all files within a folder of an asset pack or just all files in general?
My application is using the Apple demo code to load a file from an Apple hosted asset pack:
let descriptor = try AssetPackManager.shared.descriptor(for: "NAV/NavData.db3")
defer {
try descriptor.close()
}
if let path = path(for: descriptor) {
self.database = try Database(path: path)
}
As my "Navigation Data" is updated each month with an updated asset pack I would like to have the name of the .db3 file reflect the current data cycle (e.g. NAV2601.db3, NAV2602.db3, ...)
Ideally I would like to iterate over all files within the NAV folder of the current asset pack and pick the most recent one.
Unfortunately, neither the AssetPackManager nor the AssetPack object seem to include an API for this.
It would be cool to have something like:
let files = try AssetPackManager.shared.files(for: "NAV/")
for file in files {
//Check and load
}
What are guidelines for apps being released in the US App Store in order to comply with The Texas App Store Accountability Act?
I mean there's no way to differentiate an app downloaded in Texas from the other states and it would be ridiculous to add location awareness to an app to comply with this, so effectively it means any developer of any app for release in the US must comply with this in case it might be being used in Texas?
This new Apple API has zero background, zero context, zero example of usage, zero guidelines about how to use it in practice:

I'm facing the same problem as addressed in this discussion: After switching from legacy QLGenerators to Preview extensions on macOS I cannot debug the extensions' code in Xcode, anymore:
I launch the app with the embedded appex from Xcode in debug mode. When trying to attach to the appex process the following error is reported:
Code: 6
Failure Reason: Ensure “AppName Preview” is not already running, and matthias has permission to debug it.
User Info: {...
}
System Information
macOS Version 15.4.1 (Build 24E263)
Xcode 16.3 (23785) (Build 16E140)
Timestamp: 2025-05-12T14:07:14+02:00
I'm using a standard user account (no admin) and might miss some obvious steps.
Can someone detail the steps to debug a Preview (or Thumbnail) extension with Xcode 16? For legacy Quick Look plugins I was using "qlmanage", but that's not working on extensions.
All the best, Matthias
P.S.: Pardon me re-posting my reply as a separate thread, to increase visibility, but I'm quite desperate and couldn't find any solution on the web...
A screen time app I'm making has started telling users that their limit was reached even when they're far below their limit for the day (sometimes even at 0 minutes for the day).
This issue only started happening after upgrading my software to iOS 26.2.
Is this happening to anyone else? If so how have you found any solutions or does anyone know of any changes that could be causing this? Any help would be appreciated.
Since the iOS 26.2 update, we have been experiencing anomalous behavior with the DeviceActivityMonitor extension when utilizing the ScreenTime API. Specifically, we are receiving the eventDidReachThreshold event within a few minutes of initiating monitoring, despite configuring a high usage limit.
The process of turning off Screen Time -> restarting the device -> turning on Screen Time does not work.
Any ideas?
Thanks

I have applied for CarPlay support here Apply here to get your app approved for CarPlay use: https://developer.apple.com/contact/carplay/ but have not received any acceptance or answers. Does anyone know what to do?
Based on the documentation, I understand that the UnwantedCommunicationReporting extension works with SMS and MMS messages. However, I'd like official confirmation about support for different message types:
SMS: Appears to be supported ✅
MMS: Appears to be supported ✅
RCS (Rich Communication Services): Support unclear ❓
iMessage: Support unclear ❓
We're building a parental control app using FamilyControls (.child authorization). Our architecture:
Parent sends pause command → Firestore + FCM
Child receives push → NotificationService Extension triggers main app
Main app sets ManagedSettings Shields
Problem: If child disables Notifications in Settings and force-quits the app, we cannot enforce Shields.
What we've tried:
Firestore Realtime Listener (works only when app is running)
DeviceActivityMonitor (intervalDidStart/End only triggers at schedule boundaries, eventDidReachThreshold requires explicit app selection via FamilyActivityPicker)
Question: Is there a recommended approach for parental control apps to reliably enforce Shields when the child has disabled notifications? Or is this a known limitation?

Hello,
Recently we got a question about the keyboard sensor data collection in our research project:
"For the typing statistics, was any typing included or only messaging and notes? E.g., typing in the browser, phone search, calendar, etc?"
While I believe it should be any typing included, I was not able to find a document explicitly stating that. Could you help to confirm it or guide me to any documentation explaining it?
Thanks!
I'm building a voice-to-text keyboard extension that needs to open the main app briefly for audio recording (since keyboard extensions can't record audio), then return the user to their original app.
The flow I'm trying to achieve:
User is in WhatsApp (or Messages, Slack, etc.)
User taps "Voice" button in my keyboard
My main app opens via deep link (myapp://keyboard/dictation)
App starts recording
App automatically returns user to WhatsApp
I cannot find a way to detect which app the keyboard is running inside, or which app opened my main app via the deep link.
UIInputViewController.textDocumentProxy - No host app information available
UIApplication.OpenURLOptionsKey.sourceApplication in application(_:open:options:) - When opened from a keyboard extension, does this return the host app bundle ID or the keyboard extension bundle ID?
Private APIs (for research only, not production):
_hostBundleID on UIInputViewController - blocked/returns nil on iOS 18
KVC approaches - all blocked
Hardcoded app support - Works but requires maintaining a list of popular apps and showing multiple buttons instead of a single "Voice" button
My questions:
When a keyboard extension triggers a URL open (via SwiftUI Link or UIApplication.shared.open), what does sourceApplication contain? The host app or the keyboard extension?
Is there any supported way for a main app to know which app it was launched from, specifically when that launch originated from a keyboard extension?
How do apps like "Wispr Flow" achieve seamless return-to-app with a single voice button? They seem to auto-return to whatever app the user was in.
Environment:
iOS 18.0+
Xcode 16
SwiftUI keyboard using KeyboardKit
Any guidance on the recommended approach would be greatly appreciated. I understand there may be privacy reasons for limiting host app detection, but the UX of requiring users to manually swipe back (or tap app-specific buttons) is significantly worse than automatic return.
Project Background:
I am developing a third-party custom keyboard for iOS whose primary feature is real-time voice input.
In my current design, responsibilities are split as follows:
1. The container (main) app is responsible for:
Audio recording
Speech recognition (ASR)
2. The keyboard extension is responsible for:
Providing the keyboard UI
Initiating the voice input workflow
Receiving transcription results via an App Group
Inserting recognized text into the active text field using textDocumentProxy.insertText(_:)
Intended User Flow
The intended workflow is:
The user is typing in a third-party app (for example, WeChat) using my custom keyboard.
The user taps a “Voice Input” button in the keyboard extension.
The keyboard extension activates the container app so that audio recording and ASR can begin.
After recording has started, control returns to the original app where the user was typing.
The container app continues running in the background, maintaining active audio recording and ASR.
Recognized text is continuously streamed back to the keyboard extension and inserted into the current cursor position in real time.
Observed Industry Behavior
Some popular third-party keyboards on iOS, such as WeChat Keyboard and Doubao Keyboard, appear to provide a similar user experience in which:
Voice input can be initiated directly from the keyboard while typing in another app.
The user remains (or returns) in the original typing context after voice input starts.
Speech recognition continues and text is streamed into the active text field without interrupting the typing experience.
I would like to better understand how this type of workflow aligns with iOS platform capabilities and supported APIs.
My Questions
Is it supported by iOS public APIs for a custom keyboard extension to activate its container app to start audio recording and ASR, then return to the original host app while the container app continues recording and performing ASR in the background?
If this workflow is not supported, are there any Apple-recommended or supported alternative architectures for achieving a similar user experience, especially when audio recording and ASR logic are currently implemented in the container app rather than in the keyboard extension?
Goal
My goal is to design a solution that is fully compliant with iOS public APIs and platform constraints, while providing a real-time voice input experience comparable to existing third-party keyboards on the platform.
Any guidance on supported APIs, recommended architectures, or relevant documentation would be greatly appreciated.
I am trying to port my sandboxed macOS app completely over to iOS using a Catalyst target. In my macOS app, I use 'SwiftySandboxFileAccess' package to add a symlink to '~/Library/PDF Services' so that the 'share to my app' menuItem shows up in the macOS Print Panel (in the PDF menu). It is critical for the function of my app to have this work on macOS.
In the Catalyst target, I am having problems gaining access to '~/Library'. I have tried having the user select the folder, but the picker always returns 'canceled'. I have a test app that illustrates this.
The test app tries to coax the user into selecting the library folder and then it is supposed to bookmark the location, but I am unable to get this far.
As an aside, macOS should probably automatically add an entry to the Print Panel when the app includes PDF as a document type in XCode; it would save a lot of hassle and avoid having to go outside of the sandbox. However, I cannot wait for that. Hopefully someone can help.
Download Test App from iCloud
(If you have problems downloading the file, it might be because of some iCloud share setting that I am not aware of. Just tell me and I'll figure something out.)

Hello everyone,
I’m experiencing a WeatherKit issue that occurs consistently on both the iOS 26.2 Simulator and a real device running iOS 26.2.
Environment:
Xcode: latest
iOS: 26.2
Occurs on: Simulator AND physical device
WeatherKit usage: via WeatherService API (not manual REST)
Location Services: authorized (When In Use / Always)
Issue:
WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2
"The operation couldn’t be completed."
Already verified:
WeatherKit capability is enabled for the App ID
com.apple.developer.weatherkit entitlement is present
Bundle ID matches the App ID
App is signed with the correct Team ID
Behavior is identical on Simulator and physical device
Error occurs before any WeatherKit response is returned
Questions:
Is this a known issue with WeatherKit on iOS 26.2?
Are there any known limitations or requirements for WeatherService
related to WeatherDaemon validation?
Is there a recommended way to diagnose why WeatherDaemon
rejects the request with Code=2?
Code:
private let weatherService = WeatherService()

Hey!
I'm trying to create an XPC messaging feature between my daemon and main application.
I'm trying to use the new Swift low-level API available from macOS 14.0. The documentation is extremely confusing when looking at it from Swift:
The xpc_listener_t type
Seems to be something I shouldn't use in the Swift API, and would rather have to use XPCListener.
Also, it appears to have no public API other than the xpc_listener_set_peer_code_signing_requirement function. Which would make it impossible to create this type.
However, when going into xpc.h, one can see that there is an API in fact:
API_AVAILABLE(macos(14.0), macCatalyst(17.0))
API_UNAVAILABLE(ios, tvos, watchos)
XPC_EXPORT XPC_SWIFT_NOEXPORT XPC_RETURNS_RETAINED XPC_WARN_RESULT
xpc_listener_t _Nullable
xpc_listener_create(const char * service,
dispatch_queue_t _Nullable target_queue,
xpc_listener_create_flags_t flags,
xpc_listener_incoming_session_handler_t incoming_session_handler,
xpc_rich_error_t _Nullable * _Nullable error_out);
which is a very unusual declaration - the first parameter for example shows up as Int8 type in Swift. Not to mention I haven't been able to create the next parameter, xpc_listener_create_flags_t at all, even though it seems to be a UInt64-based flag based on the C declaration, but passing UInt64(0) throws a compiler error. It really seems like something I shouldn't use from Swift.
But then again, the extremely important security-related API mentioned above, xpc_listener_set_peer_code_signing_requirement can only take an xpc_listener_t object as a parameter, not an XPCListener type.
There seems to be no conversion available between the two. However the documentation in the XPC framework seems to be telling the story of these two types being very equal, because of the following:
The xpc_session_t type
seemingly again has only deprecated methods mostly, the important one staying behind is xpc_session_set_peer_code_signing_requirement.
However, this would again require the creation of an xpc_session_t object, for which in the XPC framework one will find declarations like:
@available(macOS, introduced: 13.0, deprecated: 14.0, renamed: "XPCSession")
@available(macCatalyst, introduced: 16.0, deprecated: 17.0, renamed: "XPCSession")
@available(iOS, unavailable)
@available(tvOS, unavailable)
@available(watchOS, unavailable)
public typealias xpc_session_t = OS_xpc_object
plus basically all API of XPCSession being originally declared as xpc_session_* APIs and all of them having deprecated: 14.0, renamed: * marks. This is telling me xpc_session_t and XPCSession are in fact the same/same-ish.
But again, there is seemingly no conversion between these two types. Which brings me to again being unable to create a code signing requirement for the XPCSession object.
I've read some older forum posts, and I saw Apple Engineers admitting the code signing requirement APIs are missing from the new Swift APIs, however they seem to have been added in macOS 14.4 - although it appears to have been mistakenly added to the C-family functions, which have not been exposed to Swift correctly, because they still use the deprecated xpc_listener_t and xpc_session_t types.
So my question is: what is going on here? :) Making XPC connections without a code signing requirement in 2025 seems like a no-go, so do I have to still stick with C - even though this new API seems to be focused on Swift?
