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.

I pull an hourly UV index forecast in my app via WeatherKit, but I’ve noticed it flips back and forth between two "stable" forecasts throughout the day, as if the data source is switching between providers, as a result giving a sense of instability in the presented forecast. Is there any way to lock or specify a single forecast source for greater consistency? I have a feature that notifies users when the UV index crosses a set threshold, but these repeated “back-and-forth” changes trigger multiple alerts that feel spammy and unreliable. Any advice or best practices for handling this would be greatly appreciated.
I have been working to implement Apple's Live Caller ID feature, which requires setting up a relay server. Following Apple's guidelines, I submitted a request through the provided link to utilize Apple's relay server. However, it's been three weeks, and I have yet to receive a response. I contacted Apple Support, but they indicated that this is a technical matter beyond their scope.
Has anyone successfully received confirmation from Apple regarding the use of their relay server for Live Caller ID? If so, could you share your experience or any advice on how to proceed?
url: https://developer.apple.com/contact/request/live-caller-id-lookup/
Thank you.
I've been reading this question: https://developer.apple.com/forums/thread/701945 and watching the videos on background tasks
But can't arrive to a concrete solution.
Q1: Are there any tips (or sample app) on how to handle a launch in background in a streamlined way? How to have a shared code that is ran for both 'launch in background' & 'launch in foreground'?
Specifically the case I'm talking about is:
You set up some observance of some OS callback at a Foo screen of your app. Example app should request and then send push-to-start live activity tokens to server. Or setup location tracking.
App is then suspended and then later terminated but is eligible for relaunch
App is then launched in background because it has requested a push-to-start live activity token or an update for location tracking.
User DOES NOT go back to screen Foo.
So at this point app is no longer tracking / listening to updates for token update or location changes.
How should I architecture my code for this? I'm trying to see if there's a an approach where I can avoid having multiple places in code where I do the same thing. Currently what I'm doing is as such:
Q2: Is it then correct to say that anytime you've launched your app, whether it's in foreground or background then you must immediately match 'all observations done by the previous app launch'?
Like store items in UserDefaults and upon launch retrieve them and do:
handleGeneralAppLaunchFlow()
// ALSO
if defaults.contains("didLastLaunchSetupLiveActivtiyTokenObservance") {
for await ptsToken in Activity<EmojiRangers> .pushToStartTokenUpdates {
...
}
}
if defaults.contains("didLastLaunchSetupLocationTracking") {
locationManager = CLLocationManager()
locationManager?.delegate = itsDelegate
locationManager?.allowsBackgroundLocationUpdates = true
locationManager?.showsBackgroundLocationIndicator = true
locationManager?.startUpdatingLocation()
}
// Other checks for prior observance setup
Q3: Actually I think even if app is launched in foreground then because you may not end up at screen Foo again, then you must setup things regardless of app state and just based on prior observations set. Right?
Q4: And then later if the user ever made it again to screen Foo, then we just skip the re-do of the observance, or maybe to just keep things simple, we'd just redo without over-engineering things?
I tried to mark my questions with Q1- Q4.
I have my application named "TestDataPro" in apple store.
When I open the application and click on apple icon, my application crash.
It is working fine in MACOS version 14.2.1.
But it is causing crash in MACOS version 14.5 and 14.6 with having Apple M1 or M2 chip.
While for the same MACOS version with having intel chip it is working fine.
I have attached crash log. Can you please help me to find the root cause for this?

Hello there!
So Im trying to upload an app to the App Store for iphone and Ipad, but from the revision team the same message always appears, the app crash.
So I know the "it works on my computer" sounds bad but....works on my computer and my test system.
Dont know what to do since I dont know how to replicate the error.
This is the rely they sent me:
Issue Description
The app exhibited one or more bugs that would negatively impact users.
Bug description: at time of review the app’s interface went blank at launch.
Review device details:
Device type: iPad Air (5th generation)
OS version: iPadOS 18.4.1
Anyone has any idea on how can I replicate the error and maybe check the logs? Im completely blind on this one.
Subject/Title:
Critical SKAdNetwork Attribution Failures (Bug Type: 237, Failure Type: 1201 in ASDErrorDomain)
Issue Summary
We are encountering repeated SKAdNetwork attribution failures (failureType: 1201 in ASDErrorDomain) for ad impression events processed through the ad network mj797d8u6f.skadnetwork. These failures are causing significant revenue losses, as ad impressions are not being properly attributed to installs.
The issue occurs across multiple campaigns and involves both SKAdNetwork API 3.0 and 4.0, suggesting a systemic problem with attribution validation or network communication.
This problem is critical as it disrupts advertisers’ ability to track conversions, optimize campaigns, and allocate budgets effectively.
Technical Details
Key Logs:
Below are anonymized samples of the failed SKAdNetwork events:

}
Failure Details:
Failure Type: 1201
Failure Domain: ASDErrorDomain
Ad Network ID: mj797d8u6f.skadnetwork
API Versions Affected: 3.0, 4.0
Timeframe of Failures: All logs occur within 2025-01-07 22:00:00 UTC to 23:00:00 UTC.
Environment:
OS Version: iOS 18.2.1 (Build 22C161).
Device Type: iPhone (hardwareFamily: iPhone).
App Configuration: Includes the ad network ID in the Info.plist under SKAdNetworkItems.
Impact Details
Financial Loss:
Based on failure rates, we estimate $20–$65/day per advertiser for small campaigns and $75–$375/day per advertiser for larger campaigns.
If 100 advertisers are affected, daily losses range from $2,000–$37,500.
Over a week, losses could exceed $70,000 to $262,500 or more.
Operational Impact:
Advertisers cannot track installs or optimize campaigns, leading to inefficient ad spending and potential budget reallocation to other networks.
Damaged trust between advertisers and the ad network.
Reputation Risk:
Continued failures harm the credibility of the SKAdNetwork framework, critical in a post-ATT (App Tracking Transparency) ecosystem.
Steps to Reproduce
Serve an ad impression through the ad network mj797d8u6f.skadnetwork.
Monitor SKAdNetwork attribution for that impression.
Observe repeated failures (failureType: 1201) despite the resultType: finalized status.
Recommendations for Investigation
Attribution Timeout:
Verify if these failures stem from delayed responses or missed attribution windows.
Ad Network Configuration:
Confirm the ad network’s integration complies with SKAdNetwork API 3.0 and 4.0 requirements.
Infrastructure Review:
Investigate potential bottlenecks or failures in Apple’s attribution servers (ASDErrorDomain) or communication delays.

We've been using the WeatherKit API for a few years now. Everything has been pretty stable. We'll periodically get 404 errors, but they usually disappear within a couple days.
Starting March 5th we've again been getting 404 errors that slowly ramped up to March 20th and continued. We have had no code changes on our end, so something seems to have changed / broken on the server side of things.
Here are some example API calls that are giving us a 404 error now
https://weatherkit.apple.com/api/v1/weather/en/35.9981205/-78.8920444?dataSets=forecastDaily&dailyStart=2025-03-21T05:00:00Z&timezone=America/New_York&countryCode=US
https://weatherkit.apple.com/api/v1/weather/en/41.4789363/-81.7404134?dataSets=forecastDaily&dailyStart=2025-03-21T04:56:00Z&timezone=America/New_York&countryCode=US
Does anyone have any insights or information on this?
Also if Apple is listening, an error more meaningful than 404 would be much much appreciated.
Hey,
I'm trying to update my old app that used DarkSky to WeatherKit, and struggling. I always get:
ailed to generate jwt token for: com.apple.weatherkit.authservice with error: Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)"
This is regardless if I do it on my iPad, or in the simulator. I have done the following:
Selected WeatherKit on the Capabilities and App Services tabs of the Identifier section on developer.
Put it under signing and capabilities in XCode
I've tried making a new provisioning profile, cleaning build folder, etc. Not sure what to do here. I suspect part of this problem is that I developed this app in 2018 and now I'm trying to update it.
I am able to run the app on TestFlight, but not as an internal tester. Apple won't let me, so I have to add myself as an external tester.
Thanks for any help you can provide!
Hi! We are having a hard time with the universal link, help is appreciated! Thanks in advance!
The universal link doesn't work after installation for some time. A user has to wait for from 5 to a couple of hours after the app is installed on the device.
This has also affected App reviewers since we need the universal link to work for successful login. Each submission will receive a rejection of we cannot login and it will be approved until we kindly ask them to try again.
I believe the JSON is delivered to devices by Apple's CDN system and the fact that it works on most devices most of the time should imply that we have a valid apple-app-site-association setup.
So I am really confused about the wait time, which is giving us trouble with app review and a bad user experience
Hi everyone. Does anyone know if there a way to get a list of watch faces for a paired Apple Watch, or to set the current watch face? Or is this just not allowed?
Have looked through the WatchKit, WatchConnectivity, and WatchOS documentation and haven't found anything.
Hi Team,
We’re encountering a device-specific issue with our SMS Message Filter extension. The extension works as expected on an iPhone 11 running iOS 16.6, but it does not trigger on an iPhone 12 Pro running iOS 16.7.
Key Observations:
The extension is implemented using ILMessageFilterExtension and calls messageFilterOffline(appGroupIdentifier:for:) from our shared library.
The App Group is properly configured and accessible across the app and extension.
The extension is enabled under Settings > Messages > Unknown & Spam.
There are no crashes or error logs reported on the affected device.
The issue is consistently reproducible — it works on one device but not the other.
We’re wondering if this could be a regression or a device-specific behavior change introduced in iOS 16.7.
Has anyone encountered similar inconsistencies in Message Filter extensions across different iOS versions or device models?
Any guidance or suggestions would be greatly appreciated.
Thanks in advance!
When using CallKit in my flutter app audio(both mic and speaker) stop working. When not using call kit to answer calls the app work fine. I am using the flutter flutter_callkit_incoming to use callkit and flutter_webrtc for the telephony. Flutter_callkit_incoming has some boilerplate code code include sections to uncomment when using webrtc and I have seen multiple fixes to suggest to make sure the to configure sharedAudioSession before the callkit is sent. Neither of this approaches seemed to have worked.
We have created an app that uses Appintents to plug into Siri. However, launching the app >sometimes< will launch a menu that will let the user choose between the app and Contacts. Why? How can I tell Siri to not ask for Contacts?
Hi,
I'm trying to setup PIR service for live caller id lookup (in python but based on swift example: https://github.com/apple/live-caller-id-lookup-example). The swift example provides utilities for database setup and encryption, but I can't find any specification about which key is used for database encryption and how the ios system knows about this key in order to be able to construct the PIR requests.
So my question is how does the PIR service communicate the secret key to ios system or vice versa? (specific to the test environment, before onboarding)
In the mobile application we are developing we need to use the "SMS and MMS Message Filtering" functionality to analyze SMS messages received from unknown senders.
The questions that arise about the use of this functionality are:
Does this functionality allow these messages to be sent to solutions deployed in Microsoft Azure?.
If the previous case is confirmed, could we use Rest APIs that we already have deployed in Azure?.
If it were not possible to configure access to an existing Rest API, what would be the definition of the API to be implemented in the cloud for this service?.
And finally, how would the configuration of access permissions to this API deployed in the cloud be?.
Hi,
I’m trying to get an array of strings from the user using AppIntents, but I’m encountering an issue. The shortcut ends without prompting the user for input or saving the value, though it doesn’t crash. I need to get the user to input multiple tasks in an array, but the current approach isn’t working as expected.
Here’s the current method I’m using:
// Short code snippet showing the current method
private func collectTasks() async throws -> [String] {
var collectedTasks: [String] = tasks ?? []
while true {
if !collectedTasks.isEmpty {
let addMore = try await $input.requestConfirmation("Would you like to add another task?")
if !addMore {
break
}
}
let newTask = try await $input.requestValue("Please enter a task:")
collectedTasks.append(newTask)
}
return collectedTasks
}
The Call
func perform() async throws -> some IntentResult {
let finalTasks = try await collectTasks()
// Some more Code
}
Any advice or suggestions would be appreciated. Thanks in advance!
Hi Apple Developer,
I’m working on a message-filtering application and reviewing Apple's documentation on message filtering. The documentation clearly states that MMS messages can be filtered. (https://developer.apple.com/documentation/identitylookup/sms-and-mms-message-filtering)
When we refer to MMS, it includes images, short videos, and other supported multimedia formats. However, the ILMessageFilterQueryRequest only provides the message body as a String, meaning we can access text and links but not images or other media files.
Could you please confirm whether Apple allows third-party applications to access multimedia content sent from unknown numbers?
Looking forward to your quick response.
Thanks,

Hi Team,
We are encountering issues while implementing the live translation feature in our VoIP application using CallKit on iOS 26.0. Specifically, we are attempting to use the CXSetTranslatingCallAction transaction to enable translation programmatically during an active call.
However, executing this transaction results in the following error:
"Couldn't communicate with a helper application."
This occurs consistently when we attempt to trigger the translation setup without user interaction. We are seeking clarification on the following points:
Is it possible to enable CallKit's live translation feature using CXSetTranslatingCallAction purely programmatically, without requiring the user to interact with the system-provided Call UI?
What does the above error indicate in the context of CXSetTranslatingCallAction? Are there specific conditions, entitlements, or background service requirements that must be fulfilled to communicate with CallKit?
Code snippet:
let translationAction = CXSetTranslatingCallAction(call: callUUID, isTranslating: true, localLocale: Locale.init(identifier: "es-ES"), remoteLocale: Locale(identifier: "en-US"))
let transaction = CXTransaction(action: translationAction)
callController.request(transaction)
We would deeply appreciate any guidance you can provide regarding the feasibility of our approach and how to address this error.
Thank you for your support.
I've noticed that very consistently the Weatherkit API times out when I make a large(-ish) number of calls at 7am east coast time.
If I make x calls between 7:00:00 and 7:01:00 about half of them time out (as do retries.)
If I make 2x the calls between 7:15:00 and 7:16:00 there are close to zero time outs.
I've looked at the logs, at the calls per second, etc., and there is no difference between 7 and 7:15.
So, I'm not hitting a rate limit. It seems like Weatherkit itself just can't handle the traffic at peak times.
Is there any other explanation? Does Apple intend to make sure the API can handle all the traffic they are getting paid to handle?
