I am implementing a custom SMS filter using the IdentityLookup framework. My goal is to authenticate the network requests made via context.deferQueryRequestToNetwork using a user-specific JWT token generated in the containing (main) app after a successful login.

What I want to achieve now is that when the app is not running, upon receiving a notification, it displays an interface similar to CallKit with accept and decline buttons.
Here is part of my code:
@available(iOS 17.4, *)
class LiveCommunicationManager: NSObject, ConversationManagerDelegate {
static let shared = LiveCommunicationManager()
var isInvalidate:Bool = false
var configuration: ConversationManager!
override init() {
let config = ConversationManager.Configuration(
ringtoneName: "notes_of_the_optimistic",
iconTemplateImageData: UIImage(named: "AppIcon")?.pngData(), // 图标的 PNG 数据
maximumConversationGroups: 1, // 最大对话组数
maximumConversationsPerConversationGroup: 1, // 每个对话组内最大对话数
includesConversationInRecents: false, // 是否在通话记录中显示
supportsVideo: false, // 是否支持视频
supportedHandleTypes: [.generic,.phoneNumber,.emailAddress] // 支持的通话类型
)
configuration = ConversationManager.init(configuration: config)
}
func reportIncomingCall(uuid: UUID, callerName: String) {
configuration.delegate = self
let local = Handle(type: .generic, value: callerName, displayName: callerName)
let update = Conversation.Update(localMember: local,members: [local],activeRemoteMembers: [local])
Task{
do {
try await configuration.reportNewIncomingConversation(uuid: uuid, update: update)
print("成功报告新来电")
} catch {
print("报告新来电失败: \(error.localizedDescription)")
}
}
}
func conversationManager(_ manager: ConversationManager, conversationChanged conversation: Conversation) {
print("会话状态改变了")
}
func conversationManagerDidBegin(_ manager: ConversationManager) {
print("会话已经开始了")
manager.delegate = self
}
func conversationManagerDidReset(_ manager: ConversationManager) {
print("会话将要清除了")
}
func conversationManager(_ manager: ConversationManager, perform action: ConversationAction) {
print("会话接听了")
configuration.invalidate()
}
func conversationManager(_ manager: ConversationManager, timedOutPerforming action: ConversationAction) {
print("会话超时了")
}
func conversationManager(_ manager: ConversationManager, didActivate audioSession: AVAudioSession) {
print("会话激活了")
}
func conversationManager(_ manager: ConversationManager, didDeactivate audioSession: AVAudioSession) {
print("会话死亡了")
}
}
在Appdelegate里设置了这些:
func application(_ application: UIApplication,
didReceiveRemoteNotification userInfo: [AnyHashable: Any],
fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
// 在这里处理离线推送通知
completionHandler(.noData) // 返回后台任务完成
if let aps = userInfo["aps"] as? [String: Any],
let alert = aps["alert"] as? [String : Any]{
// 静默推送的处理逻辑
if #available(iOS 17.4, *) {
let manager = LiveCommunicationManager.shared
if manager.isInvalidate { return }
if let msgType = userInfo["msgType"] as? Int{
if msgType == 5{
manager.configuration.invalidate()
}else{
let callerName = alert["title"] as? String ?? "Fanvil"
manager.reportIncomingCall(uuid: UUID(), callerName: callerName)
}
}
}
}
}
Xcode has been configured with the necessary capabilities, such as Background Fetch, Voice over IP, Background Processing, and Push Notification.
The issue now is that sometimes the code works as expected, allowing the app to wake up when not running and displaying the system interface with accept and decline buttons. However, after a few successful attempts, the app stops waking up, and no notification appears. But when I manually open the app, the didReceiveRemoteNotification method gets triggered.
I’d like to know why this stops working after a few times.
find my在添加配件是,持续一直卡在“即将完成设置”这一步.这是由于什么原因呢?而且一直保持很长时间,也不会退出,也不会提示任何错误信息。
Hello,
If I fire an alarm using AlarmKit, using a ringtone that lengths less than 30 seconds, in the last version of iOS (26.0) the sound doesn't repeat. (After about 30 seconds, the sounds stops).
BUT in the current version of iOS (26.1), the sound repeats until we slide Stop, thing that I doesn't want.
So, is there a way to restore the previous behavior? Or is there a property that can fill this lack?
Thank you very much.

We’re seeing unexpected NFC behavior once our app has 50+ Advanced App Clips created.
Expected:
Scanning an NFC tag with a URL that is NOT an App Clip invocation should show the standard “Open in Safari” notification.
Actual:
After we create ~50+ Advanced App Clips, scanning NFC tags for URLs on the same domain that are not associated with App Clips consistently shows “CPSErrorDomain error 2” instead of the Safari prompt.
QR codes for the same non–App Clip URLs work as expected (shows Safari prompt).
Clearing the App Clips “Experience Cache” sometimes helps briefly, but the error returns on consequent scans.
Notes:
Domain has valid AASA. App Clip invocation URLs work as expected.
The issue appears tied to the number of Advanced App Clips configured. Below ~50, non–App Clip NFC scans behave correctly; above that, they fail.
Affected across multiple devices and iOS versions tested.
Repro steps:
Configure 50+ Advanced App Clips for paths on a single domain.
Encode a different URL on the same domain that is NOT listed as an App Clip invocation into an NFC tag.
Scan the NFC tag on iPhone.
Observe “CPSErrorDomain error 2” instead of the “Open in Safari” notification.
Impact: blocks our NFC use case for regular web links once we scale App Clip experiences.

I want to monitor again from the bellow function of DeviceActivityMonitorExtension. I have the function of startMonitoring like this.
override func eventDidReachThreshold(_ event: DeviceActivityEvent.Name, activity: DeviceActivityName) {
super.eventDidReachThreshold(event, activity: activity)
startMonitoring()
}
public func startMonitoring() {
let startTime = DateComponents(hour: 0, minute: 0, second: 0)
let endTime = DateComponents(hour: 23, minute: 59, second: 59)//DateComponents(hour: 11, minute: 0, second: 0)//
let schedule = DeviceActivitySchedule(
intervalStart: startTime,//DateComponents(hour: 0, minute: 0, second: 0),
intervalEnd: endTime,
repeats: true
//warningTime: DateComponents(minute:1)
)
let selection: FamilyActivitySelection = savedSelection() ?? FamilyActivitySelection()
let center = DeviceActivityCenter()
let selections = self.savedSelection() ?? FamilyActivitySelection()
let applications = selections.applicationTokens
let categories = selections.categoryTokens
let webCategories = selections.webDomainTokens
let store = ManagedSettingsStore()
store.shield.applicationCategories = ShieldSettings.ActivityCategoryPolicy.specific(categories, except: Set())
store.shield.applications = applications
store.shield.webDomains = webCategories
let scheduleHard = DeviceActivitySchedule(
intervalStart: startTime,//DateComponents(hour: 0, minute: 0, second: 0),
intervalEnd: endTime,
repeats: true
//warningTime: DateComponents(minute:1)
)
let event = DeviceActivityEvent(
applications: selection.applicationTokens,
categories: selection.categoryTokens,
webDomains: selection.webDomainTokens,
threshold: DateComponents(minute: 0)//timeLimitToUseApp i.e for 15 mins
)
do {
try center.startMonitoring( .weekend,
during: scheduleHard,
events: [
.weekend: event,
]
)
print("ScreenTime Monitoring Started")
} catch let error {
print(error.localizedDescription)
}
}
Please provide us with a solution about starting monitoring from DeviceActivityMonitoringExtension's eventDidReachThreshold function or if there is any other way.
Hi DTS / Apple engineers,
We’re attempting to extending our screen time app target to Mac Catalyst. On iOS, FamilyControls works as expected (AuthorizationCenter + FamilyActivityPicker, then ManagedSettings shields + DeviceActivity monitoring/reporting).
On Mac Catalyst:
The project builds with FamilyControls/DeviceActivity/ManagedSettings capabilities enabled.
But attempting to request FamilyControls authorization (or present FamilyActivityPicker) fails at runtime. We see errors similar to:
Failed to get service proxy: The connection to service named com.apple.FamilyControlsAgent was invalidated: failed at lookup with error 159 - Sandbox restriction.
And our app stays authorizationStatus == .notDetermined, with the request failing.
We saw an Apple engineer suggestion to “disable App Sandbox”, but Mac Catalyst apps appear to always be sandboxed, so we can’t disable it.
Questions:
Is FamilyControls authorization supported on Mac Catalyst today? If so, what entitlement/capability is required specifically for Catalyst/macOS?
If FamilyControls auth cannot succeed on Catalyst, does that mean ManagedSettings shields and DeviceActivity monitoring/reporting are effectively unusable on Catalyst (since they depend on that authorization)?
Is there an Apple‑recommended approach for a Catalyst “portal” app that mirrors an iOS child device’s restrictions, or is local enforcement on Catalyst intentionally unsupported?
Any guidance (and any official docs that clarify current platform support) would be hugely appreciated.

Hi,
I would like to reset system window private picker alert with ScreenCapture kit. i can reset the ScreenCapture permission with tccutil reset ScreenCapture. but it does not reset the system window private picker alert. i tried deleting the application directory from container and it does not help. the system window private picker alert uses the old approval i gave and it does not prompt a new alert. How can i starta with fresh screencapture kit settings for an app in testing?
Thanks
My app is configured with the App Clip experiences, and a Clip App card pops up when an NFC tag is scanned—whether the host app is not launched, running in the background, or active in the foreground. I want to prevent the App Clip card from popping up when the host app is in the foreground; how can this be achieved?
I am a macOS software developer using Xcode and Objective-C. I have a wallpaper app on the App Store, and recently, a few users have asked if the app can be excluded from the ‘Screen Time’ statistics. Is there a way to allow users to choose whether or not the app should appear in the ‘Screen Time’ tracking? I have already set LSUIElement to YES in the info.plist, but the app is still being tracked in ‘Screen Time.
I am getting this error when I try to show device activity report view by this DeviceActivityReport(appsContext, filter: filter)
Attempt to map database failed: permission was denied. This attempt will not be retried.
I have taken access by this way. AuthorizationCenter.shared.requestAuthorization(for: .individual)
I'm encountering what appears to be a specific precedence behavior with ManagedSettingsStore.shield and would appreciate some further clarification.
My current understanding is that category-level shields take precedence over individual app allowances.
My test involved...
Using FamilyActivityPicker to select
a single target application (e.g., "Calculator," which falls under the "Utilities" category).
Using FamilyActivityPicker again to select
the category of that target application.
I applied shields using ManagedSettingsStore (named .individual):
store.shield.applicationCategories = .specific(Set([utilitiesCategoryToken]))
store.shield.applications = Set([calculatorApplicationToken])
Result:
The calculator app remains shielded, suggesting that the category-level shield on Utilities overrides the attempt to allow the individual app. I also tried this using a single picker, but received only the category token instead of all application tokens in that category.
Is this observed precedence (where store.shield.applicationCategories effectively overrides store.shield.applications for apps within the shielded category) the intended behavior?
If so, are there any mechanisms available within the main app's capabilities (potentially using a Device Activity Report Extension or Shield Extension) to allow a specific ApplicationToken if its corresponding ActivityCategoryToken is part of the store.shield.applicationCategories set?
Essentially, can store.shield.applications be used to create "allow exceptions" for individual apps that fall into an otherwise shielded category?
Additionally, I mentioned that selecting an entire category in the picker only returns the opaque category token, not any application tokens. Is there any way in which I could return both the category and all application tokens by just selecting the category?
Any insights or pointers would be greatly appreciated!
As the title suggests, I have a class marked with @Observable. Within the class I have multiple var's. When one of my var's changes (formation), I want to run an updateOrCreateContent(). I had thought I could just do this with a bit of combine, but I'm struggling to get it working...
The code below has a compile error at $formation
When I mark formation @Published, it generates a different compile error: "Invalid redeclaration of synthesized property '_formation'"
any help appreciated
thanks
class LayoutModel {
var players: [Player] = []
var formation: Formation = .f433
var cancellables = Set<AnyCancellable>()
init(players: [Player], formation: Formation) {
self.players = players
self.formation = formation
updateOrCreateContent()
$formation.sink(receiveValue: { _ in
self.updateOrCreateContent()
})
.store(in: &cancellables)
}
Is there any way I can get updates when I change CarPlay style settings?
I've tried CPSessionConfigurationDelegate.contentStyleChanged and CPTemplateApplicationSceneDelegate.contentStyleDidChange, but they always produce the same result.
When I choose:
Automatic -> I receive light in case of daylight;
Always Dark and Always Show Dark Map toggle on -> dark
Always Dark and Always Show Dark Map toggle off -> light.
But it seems to be wrong, b/c CarPlay's toolbar is still dark, and I receive light.
Is there a way to get a dark style when choosing Always Dark and Always Show Dark Map toggle off? Or at least get updates when the Always Show Dark Map toggle changes?
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

We integrated DeviceCheck framework into our app to prevent fraudulent call to our app service around one year ago.
Recently, we received a few cases related to this function over Christmas Eve period.
Based on the logs we have, it indicated both the following two functions returned errors. But we don't have the exactly errors logged and now we cannot replicate.
DCAppAttestService.shared.attestKey()
DCAppAttestService.shared.generateAssertion()
The other finding we have is some users reporting this issue recently upgraded their devices from iOS 18 to iOS 26.
So we are suspecting it's due to either the OS upgrading, or Apple's app attest service degrading.
Anyone encountered the similar issues before, or have any idea regarding the root cause? Thanks!
Hi all,
I'm trying to set up universal links for my app but it's not working.
What I want:
cogover.com → Safari (website) - NOT my app
*.cogover.com (any subdomain like abc.cogover.com) → My app
What I did:
Added applinks:*.cogover.com in Xcode
Put AASA files on all subdomains
They work fine (checked with curl)
Problem:
All links still open in Safari, not my app.
I do not put AASA on my root domain cogover.com because I don't want open my app with root domain.
I have checked TN3155: Debugging universal links | Apple Developer Documentation but it only say about universal link works with both root domain and subdomains.
Weird thing I found:
I checked how Salesforce does it - their *.force.com subdomains work perfectly. But when I tried to check their setup, (https://force.com/.well-known/apple-app-site-association) doesn't seem to exist either! So how does theirs work?
Even stranger - Apple's CDN has their file cached at (https://app-site-association.cdn-apple.com/a/v1/force.com) but the actual domain doesn't serve it. Can Apple's CDN have a file cached even if it's not on the website anymore?
Thanks for any help!
When updating an existing advanced app clip experience, the change doesn't actually apply. It shows the correct image in the UI, but when you use the app clip it shows the old image. Looking into it more, the status has "UPDATE_SUBMITTED". Seems related to this issue (https://developer.apple.com/forums/thread/810544) and this issue (https://developer.apple.com/forums/thread/810351).
I'm sitting at my house and trying to sign my test device out of my apple ID so I can sign into a Sandbox user, but now I have an hour to kill because of this terribly broken "security" feature that thinks it's in an unfamiliar location, despite being at the only location it's ever known. Looks like I'll just be disabling this feature all together.
Especially as a device with Developer Mode enabled, which gets reset regularly, there should be additional options here. Come on!
