In my application, I use CallKit and have supportsHolding = true set. During my phone call, another call comes in (e.g., GSM). I accept the incoming call and put the current call on hold.
If I end the active call myself, everything is fine, and CallKit calls the
method provider(_ provider: CXProvider, didActivate audioSession: AVAudioSession).
However, if the other party ends the call, the second call remains on hold. In the application, the user clicks on unhold, and I notify CallKit that the hold has ended.
But in this case, the didActivate method is not called at all. If I try to activate the audio myself after unhold, I receive the error:
Domain=NSOSStatusErrorDomain Code=561017449 "Session activation failed" UserInfo={NSLocalizedDescription=Session activation failed}
AVAudioSessionErrorInsufficientPriority == NSOSStatusErrorDomain Code: 561017449
What needs to be done for CallKit to activate my audio?

Here is a post to gather findings in case anyone found out what this new API does.
Apple did not include any comments or documentation and due to the generic naming we don't know what this API might does.

There is an inconsistent issue when views are rendered from the Device Activity Report Extension. This issue is noticeable only on release versions and it works fine in debug mode.
Around 80% of the times, the Report Views return blank screen and this is only the case when a weekly/monthly filter is used. Although, it works as expected for daily report views.
My questions are:
How are all the Report Activity Views working fine in debug mode but not in release mode?
How the daily activity filter works fine in the release mode but the weekly/monthly filters don't work? Is this because of a memory limit issue in the extension?
As of now, I have the family-controls(distribution) entitlement only for the app and for the extensions I only have family-controls(development) entitlement. Do I need to request for family-controls(Distribution) entitlement even for the extensions?
I have seen threads on the forum mentioning the blank screen issue associated with the DeviceActivityReport but haven't found a solution to it. Any suggestions/feedback would be of great help, thanks.

Both view and modifier versions of the FamilyActivityPicker crash randomly when selecting some items (usually the other option) throwing these in the console:

This also happens in production apps like the Opal.
The questions are:
At least how to detect it to be able to manually reload the sheet (like what Opal does and shows an alert when this happens)
How to prevent it in the first place?
I really appreciate any help you can provide.
Greetings,
I have set up two tips in my app, and my app is configured with Tips.configure([.displayFrequency(.daily)].
Tip 1 is set up with no options. Tip 2 has the IgnoresDisplayFrequency(true) option set:
var options: [Option] {
MaxDisplayCount(3)
// We want the user to see these because it's important.
IgnoresDisplayFrequency(true)
}
This option works as expected, as far as I can tell, in terms of making sure that Tip 2 is shown even if I've already seen Tip 1 today. If I interact with my app such that Tip 1 is displayed, and I then interact with it such that Tip 2 should be displayed, Tip 2 shows immediately, even though a day hasn't passed.
However, if I do this the other way around, so that Tip 2 is displayed first, and then I interact so that Tip 1 should be displayed, my expectation would be that Tip 1 is not displayed, because another tip has already been shown today. I expected that it would not be shown until the following day, since it is not configured to ignore the tip frequency.
That's not what happens, though. Tip 1 is displayed right away, even though Tip 2 has just been shown. This makes me think that setting IgnoresDisplayFrequency on Tip 2 is causing it to also be ignored when considering whether other tips should be shown.
I did try omitting IgnoresDisplayFrequency option, and then as expected, only one tip is shown on a day, no matter which one is shown first.
Hi, I have a released screentime app ScreenZen. The last few days I've seen a disturbing spike in bug reports coming from people with 17.4.1 and 17.5.1 phones with no update to the app itself. People reported they saw the issue immediately after updating their iOS version. Unfortunately it is not replicable on all phones with those versions, so we haven't been able to replicate it on our test phones.
It appears the issue is the ApplicationToken passed into ShieldActionExtension and ShieldConfigurationExtension does not match any of the ApplicationTokens that the user selected to block through FamilyControls. (The selected ApplicationTokens are being loaded through a group UserDefaults and they are indeed being loaded in the ShieldActionExtension in the bug reports).This is preventing the app from loading the correct settings and handling the blocking accordingly. I am trying to isolate this better with a new release with better logging, but would appreciate any help on this issue.
~5% of our users when downloading the iOS application from the Apple Store for the first time are unable to enrol a Passkey and experience an error saying the application is not associated with [DOMAIN].
The error message thrown by the iOS credentials API is
"The operation couldn't be completed. Application with identifier [APPID] is not associated with domain [DOMAIN]"
We have raised this via the developer support portal with case id: 102315543678
Question:
Why does the AASA file fail to fetch on app install and is there anything that can be done to force the app to fetch the file?
Can this bug be looked at urgently as it is impacting security critical functionality?
Other Debugging Observations
We have confirmed that our AASA file is correctly formatted and hosted on the Apple CDN. Under normal circumstances the association is created on install and Passkey enrolment works as intended.
We have observed that when customers uninstall/reinstall the app this often, but not always, resolves the issue. We also know this issue can resolve itself overtime without any intervention.
We have ruled out network (e.g VPN) issues and have reproduced the issue across a number of different network configurations.
We have ruled out the Keychain provider and have reproduced it across a variety of different providers and combinations of.
We observed this across multiple versions of the iOS operating system and iPhone hardware including the latest hardware and iOS version.
Hello, we are experiencing an issue that is not systematic regarding universal links on our application. In some cases, after the application is installed, the universal links do not open the application but instead open in Safari.
We have conducted tests on several devices and with the same link. In some cases, the links open the application after installation, and in other cases, they open in Safari.
I should mention that in all test cases, we did not force the opening via the menu accessible through a long press on the link.
We performed sysdiagnose in the different cases and we observed the same configuration for the universal links in the swcutil_show.txt file:
User Approval: unspecified
Site/Fmwk Approval: approved
At this stage, I do not think the problem comes from our application or the configuration of the apple-app-site-association file. Is this a known issue? Is there anything we can do on our side to work around it ?
See crash details here:- https://pastebin.com/i9u5PE4X
There's a comprehensive thread here, folks!
https://discussions.apple.com/thread/255651156?sortBy=oldest_first
Thanks for any thoughts.
Some of our users encounter an issue after updating their iPhone/iPad to iOS 17.5.1.
The tokens passed in the Shield Configuration extension don't match the tokens they selected in my app using the FamilyPicker before updating to iOS 17.5.1. It seems the tokens changed for no reason. My app can't match the token from the ShieldConfigurationDataSource to any tokens stored on my end, causing my shield screens to turn blank. The same applies to tokens in the Device Activity Report extension.
The only workaround I've found is to tell affected users to unselect and reselect apps and websites to block in my app. This gets them new tokens from the FamilyActivityPicker, which solves the issue. However, for some users, the bug reoccurs a few days later. Tokens seem to change again, causing the same issue in the Shield Configuration extension.
I am not able to reproduce the issue on my test devices so I have no sysdiagnose to attach. However, this issue is affecting other screen time apps:

A change in iOS 17.5.1 must have triggered this behaviour. Could an Apple engineer give us any updates on this?

Hi. The WWDC video of the v2 weatherkit api showed some examples for the REST API. However, they were very limited.
The documentation for the REST API is currently for the v1 weatherkit API. When will the documentation for the v2 API be released? There are some new features of the v2 that I would really like to use, but I can't without knowing the new v2 REST API specifications.
Any guidance would be much appreciated. Thanks!
I am trying to set up a message filter extension that will use shared web credentials for basic auth when calling to its ILMessageFilterExtensionNetworkURL.
I have associated domains set up for both "messagefilter:" and "webcredentials:" and the message filter IS correctly calling the ILMessageFilterExtensionNetworkURL with each message - so that part is working.
As detailed here, I have set up Shared Web Credentials and my view controller is using SecAddSharedWebCredential() to save the creds to the correct domain. Using Authorization services, the creds are auto-filled into my app's login screen. When I go under Settings > Passwords, I see the creds are saved and they are the correct creds to the corrent website that matches ILMessageFilterExtensionNetworkURL.
Regardless of all of this, the deferQueryRequestToNetwork() refuses to use the creds and implement Basic Auth in its URL call. It makes the call to the correct URL, it just won't use the Shared Web Creds for basic auth.
Any help would be greatly appreciated.

Hey there, I have a slight problem which is also known on the web, but I couldn't find any answers...
My iOS App is working with documents like pdf and images. It is made to handle invoices and upload them to an external service. The app's job is to compress those pdfs and images. Sadly the PDFKit's PDFDocument increases its size just after importing it with pdfDocument = PDFDocument(url: url) and later exporting it to an pdf file again with data = pdf.dataRepresentation() without ever modifying it.
It increases by server KB after each export. Do you have any alternatives to the renderer dataRepresentation() or a general PDFKit alternative
Thanks
I want to display device activity reports for particular selected apps. for getting a daily basis app uses time. Now, what is happening? there are 10 apps selected from the family activity picker but some apps are displayed in the list. I need all 10 apps or more that I will choose from the family activity picker. The bellow code is used for fetching reports.
var body: some View {
VStack {
DeviceActivityReport(context, filter: filter)
}
}
bellow code is used for the filter
@State public var filter = DeviceActivityFilter()
init(selectedApps: Set<ApplicationToken>, selectedCategories: Set<ActivityCategoryToken>, selectedWebDomains: Set<WebDomainToken>) {
self.selectedApps = selectedApps
self.selectedCategories = selectedCategories
self.selectedWebDomains = selectedWebDomains
self.filter = DeviceActivityFilter(
segment: .daily(
during: Calendar.current.dateInterval(
of: .weekOfYear, for: .now
)!
),
users: .all,
devices: .init([.iPhone]),
applications: selectedApps,
categories: selectedCategories,
webDomains: selectedWebDomains
)
}
You can see we selected 3 apps from family activity picker but we getting 2 apps from DeviceActivityReport extension
following code is for device activity report extension
let context: DeviceActivityReport.Context = .totalActivity
// Define the custom configuration and the resulting view for this report.
let content: (ActivityReport) -> TotalActivityView
func makeConfiguration(representing data: DeviceActivityResults<DeviceActivityData>) async -> ActivityReport {
// Reformat the data into a configuration that can be used to create
// the report's view.
var res = ""
var list: [AppDeviceActivity] = []
let totalActivityDuration = await data.flatMap { $0.activitySegments }.reduce(0, {
$0 + $1.totalActivityDuration
})
for await d in data {
res += d.user.appleID!.debugDescription
res += d.lastUpdatedDate.description
for await a in d.activitySegments{
res += a.totalActivityDuration.formatted()
for await c in a.categories {
for await ap in c.applications {
if let apptoken = ap.application.token {
let appName = (ap.application.localizedDisplayName ?? "nil")
let bundle = (ap.application.bundleIdentifier ?? "nil")
let duration = ap.totalActivityDuration
let numberOfPickups = ap.numberOfPickups
let app = AppDeviceActivity(appToken: apptoken, id: bundle, displayName: appName, duration: duration, numberOfPickups: numberOfPickups)
list.append(app)
}
}
}
}
}
return ActivityReport(totalDuration: totalActivityDuration, apps: list)
}
In iOS 18 (beta 1-4) when you set openAppWhenRun = false in your AppIntent of your live activity the perform function never gets called.
In iOS 16 and 17 my live activities work. I have downloaded other apps and in their live activities any button tab which doesn´t open the app is also doing nothing in iOS 18.
Has anyone got this working? Any comments from an Apple engineer on this?
In the documentation for the example Live Caller ID server (https://swiftpackageindex.com/apple/live-caller-id-lookup-example/main/documentation/pirservice/testinginstructions) there is an example service-config.json. file shown (without thorough documentation).
That config file, and the whole of the instructions, center around there being two datasets of numbers: block and identity.
My question is - is it possible for more than one dataset to be specified i.e. for block1 and block2 to be specified?
The use case for this would be - suppose the Live Caller ID server has a set of numbers it has identified as being nuisance callers and so it lists these in the block section. However user A might want all these nuisance callers to be blocked but user B does not. Therefore the Live Caller ID extension on the handset would need to use a different dataset on the server so that user A's calls from a set of numbers is blocked, but user B's are not.
Note that I'm not suggesting that the Caller ID server should be capable of storing individual user's preferences. All that would be required would be two data sets: one where blocked content is none and and one where blocked content is some. Then a user/app could switch between them as indicated by the user.
Is that possible?
If the database structure and service-config.json etc. is not configured to permit that, then could two different servers be set up to achieve this instead? i.e. so the server url specified in the app's extension can be set at run time and not at compile time?
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?
Hi there,
My app uses all the Screen Time API's with individual FamilyControls authorization. I've been using the API's for over 2 years (since they came out).
In iOS 18 Beta (maybe started in Beta 3?), I've been experiencing random issues. I tracked it down to where it seems like DeviceActivityMonitor extension is more likely to deadlock in iOS 18.
To reproduce: when DeviceActivityMonitorExtension.intervalDidEnd gets called, IF you call DeviceActivityCenter.startMonitoring for that SAME DeviceActivityName from the DeviceActivityMonitorExtension , the startMonitoring call deadlocks (if I pause debugger, it does not advance past DeviceActivityCenter.startMonitoring).
The bug is reported in FB14664238. It also contains a sample project where you can reproduce this.
I also note in the comment section that this is not the only way to encounter this problem. My application code (which is a lot more complicated) seems to deadlock on calling DeviceActivityCenter.activities. As a result, there seems to be an "overall trend" where, due to some changes, DeviceActivityMonitor extension is more likely to deadlock.
The steps are not reproducible on iOS 17.6. This is built using Xcode 17.4.
Thank you! 🙏

Some Apple URL schemes are documented for third-party use. It’s fine to use those URL schemes for their intended purpose.
Other Apple URL schemes are not officially documented. Their use is unsupported. If you rely on such implementation details, things might work, or they might not, and that state might change over time.
IMPORTANT If you ship via the App Store, pay attention to clause 2.5.1 of the App Review Guidelines.
The Apple URL scheme documentation is not always easy to find. I’m aware of the following:
Apple URL Scheme Reference
QA1924 Opening Keyboard Settings from a Keyboard Extension [This Q&A was retired years ago.]
Preparing your app to be the default messaging app
The doc comments for es_new_client in <EndpointSecurity/ESClient.h>
Developer > Bug Reporting describes the applefeedback scheme
Additionally, as questions about this most commonly crop up in the context of opening Settings (System Settings on macOS), I wanted to highlight the following:
UIApplication.openSettingsURLString property (in Objective-C this is UIApplicationOpenSettingsURLString)
UIApplication.openNotificationSettingsURLString property (in Objective-C this is UIApplicationOpenNotificationSettingsURLString)
UIApplication.openDefaultApplicationsSettingsURLString property (in Objective-C this is UIApplicationOpenDefaultApplicationsSettingsURLString)
AccessibilitySettings.openSettings(for:) method
FIFinderSyncController.showExtensionManagementInterface() class method
SMAppService.openSystemSettingsLoginItems() class method
VSOpenTVProviderSettingsURLString global
CXCallDirectoryManager.openSettings(completionHandler:) method
SFSafariSettings.openExportBrowsingDataSettings() method
SFSafariSettings.openExtensionsSettings(forIdentifiers:) method
If your app needs to perform some action that’s not covered by the above, file an enhancement request for a supported way to do that. Make sure to describes your use case in detail.
Share and Enjoy

I’ve set up a focus filter, but the perform() method in SetFocusFilterIntent isn't called when the focus mode is toggled on or off on my iPhone since I updated to iOS 18 beta (22A5326f).
I can reproduce the issue for my app, but focus filters are also broken for any third-party apps installed on my phone, so I guess it's not specific to how I've implemented my filter intent.
This used to work perfectly on iOS 17. I didn't change a single line of code, and it broke completely on the latest iOS 18 beta.
I've filed a bug report including a sysdiagnose (FB14715113).
To the developers out there, is this something you are also observing in your apps?
