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.

Hello,
I've been encountering some challenges while working with NWConnectionGroup and NWMulticastGroup for multicast operations on iOS. I have a few doubts and issues that I would like to address:
1. NWMulticastGroup Initialization
It seems that when initializing NWMulticastGroup, only one NWEndpoint can be passed, and attempting to pass multiple endpoints results in failure. Can someone confirm if this behavior is correct?
2. Interface Level Control
Upon initializing NWConnectionGroup, it appears that packets are received on all interfaces without the ability to control this at the interface level. Is this correct? If not is there a way to configure NWConnectionGroup to receive packets on all interfaces?
3. Sending Behavior
During the send operation, it appears that the data is sent through any one of the available interfaces, and there doesn't seem to be an option to configure it to send through all available endpoints. Is there a way to enable sending data through all available endpoints?
Any insights, guidance, or solutions to these issues would be greatly appreciated. Has anyone else encountered similar problems or found workarounds for these limitations?
Thank you for your assistance and support.
Thanks,
Harshal
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.
Hi, I'm developing a Live Activity Widget that shows a count down timer.
In the current solution I have a stop watch that is responsible for handling the start, stop, resume, reset function.
When the stop watch starts I have timer that calls on an updateTime function every 0.2 seconds. This works well.
The problems comes when I try to use my stop watch in the Live Activity Widget. I have a timer that updates the live activity attributes with content every 0.5 second.
// Start the activity
let activity = try? Activity.request(...
DispatchQueue.main.async {
self.logger.log("Start internal timer")
self.timer = Timer.scheduledTimer(withTimeInterval:0.5, repeats: true) { _ in
self.logger.log("Update activity widget.")
self.updateActivity()
}
}
Is this a correct approach? If not what should I use to implement a stop watch with a count down timer and a corresponding progress bar/view?
~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 ?

Hello all 👋
I'm getting unexpected behavior when testing FinanceKit for my app and was hoping to get assistance.
Pre-reqs (defined at https://developer.apple.com/documentation/financekit):
I've been given the FinanceKit entitlement
I have the com.apple.developer.financekit entitlement set to financial-data
I also have NSFinancialDataDescription set in Info.plist.
I am targeting iOS 17.4 (a physical device)
When I call FinanceStore.shared.requestAuthorization(), I immediately get a denied status without any alert dialogs.
No data about my app is listed in Settings > Privacy & Security > Wallet
Any idea what else is needed here?
Thanks so much for the help!

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?

I work on a macOS application that functions as a daemon. To test it, I:
Compile executables.
Use pkgbuild and productbuild to build an application bundle.
Use codesign and notarytool to sign and notarize the app.
Install the app with /usr/sbin/installer -target LocalSystem -pkg .... This often overwrites the previous version of the app.
Sometimes, the installation fails at the postinstall stage, when it can not find the application's install directory. We explicitly check for this error in our script:
if ! [ -d "$APP_INSTALL_DIR"/Contents ]; then
echo "directory ${APP_INSTALL_DIR}/Contents is missing"
exit 1
fi
This is unexpected!
Even worse, some of our customers have occasionally seen the same issue!
We use a postinstall script in order to install files into the /Library/LaunchDaemons and /Library/ LaunchAgents directories, and start the agent with launchctl bootstrap.
Our preinstall script makes sure that the previous version of our application is fully uninstalled (so there is no confusion), and we wonder if that is part of the problem.
While researching this error, I ran across a discussion of a similar issue on Stackoverflow: <https:// stackoverflow.com/questions/19283889>. One of the commenters there wrote:
It appears that the OS X installer uses information about already installed packages and application bundles in order to decide where and if to install new packages. As a result, sometimes my installer did not install any files whatsoever, and sometimes it just overwrote the .app bundle in my build tree. Not necessarily the one used to build the installer, but any .app bundle that OS X had found. In order to get the installer to install the files properly I had to do two things:
Tell OS X to forget about the installed package. sudo pkgutil --forget <package id> Not sure if this is needed for you nor in my case, but it is probably a good idea anyway.
Delete all existing .app bundles for the app. If I didn't do this, the existing app bundle was overwritten on install instead of the app being placed in /Applications. Maybe there is a way to prevent this while building the installer package, but I haven't found it.
On the other hand, the man page for pkgutil says not to use --forget from an installer:
Discard all receipt data about package-id, but do not touch the installed files. DO NOT use this command from an installer package script to fix broken package design.
What is the correct approach to fix this problem?

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.

The problem is that when I read out the text in a PDF with page.string or page.attributedString, the context of the lines is lost. Instead of
TermA....23,45
TermB....2,13
in an index document
TermA
TermB
23,45
2,13
is issued. The context of the lines (and the sequence of the letters) is lost. Is there a way to read the text from a PDF line by line?
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?
I'm just trying to display an image that is stored in the local filesystem, but the more I dig into this the more confused I get.
So previously I used this code (it's simplified):
func findImage(name: String) -> UIImage? {
do {
let url = try FileManager.default.url(for: .applicationSupportDirectory,
in: .userDomainMask,
appropriateFor: nil,
create: false)
.appendingPathComponent("MyFolder")
.appendingPathComponent("\(name).png")
guard let image = UIImage(contentsOfFile: url.path) else {
return nil
}
return image
} catch {
print(error.localizedDescription)
}
return nil
}
Notice I create the URL with just .appendingPathComponent() and turning URL to path via url.path.
It works! So what's the question?
In Improving performance and stability when accessing the file system I've read that you better use the new appendingPathComponent(_:isDirectory:), that's good, will do.
Also url.path is deprecated in iOS18. Should I use url.path(percentEncoded:) instead? What should be the value of percentEncoded when accessing the local filesystem?
In this adjacent thread I've read:
Don't use UIImage(contentsOfFile:) either, because it's a path-based API. There's no URL-based equivalent, which is an Apple clue that should be doing something else.
Is this true? Then how should I store and load my images?
Just FYI, I create images like this:
private func generateThumbnail(name: String) {
guard let drawingWidth = canvasGeo?.size.width,
let drawingHeight = canvasGeo?.size.height else { return }
let thumbnailRect = CGRect(x: 0, y: 0, width: drawingWidth, height: drawingHeight)
Task {
UITraitCollection(userInterfaceStyle: .light).performAsCurrent {
let image = self.canvasView.drawing.image(from: thumbnailRect, scale: UIScreen.main.scale)
guard let data = image.pngData() else { return } // -- HERE
do {
try FileManager.default.createDirectory(at: try FileManager.default.url(for: .applicationSupportDirectory,
in: .userDomainMask,
appropriateFor: nil,
create: true)
.appendingPathComponent("MyFolder"),
withIntermediateDirectories: true,
attributes: nil)
let filename = "\(name).png"
let url = try FileManager.default.url(for: .applicationSupportDirectory,
in: .userDomainMask,
appropriateFor: nil,
create: true)
.appendingPathComponent("MyFolder")
.appendingPathComponent(filename)
try data.write(to: url, options: .atomic) // -- and HERE
} catch {
print(error.localizedDescription)
}
}
}
}
My usecase — just save the user's PencilKit Canvas as an image and display it back to him on a different View. I'm on SwiftUI and iOS 16+.
Would be happy to learn the correct way, thanks!
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
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.

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?
