I am using the WeatherKit REST API with hourlyStart/hourlyEnd parameters
to request up to 240 hours of forecast data.
However, when requesting later in the day, the API returns fewer than
240 hourly forecasts — e.g., 239 at 08:00, 238 at 09:00, etc. and goes up to 224 for 23:00
It appears the returned list is contiguous but truncated at the end
compared to the full 240-hour window. I have also tried getting the data after sometime, like 09:00 data at 09:45 but still was missing the same data at the end.
Is this expected WeatherKit behavior or a bug? If it’s expected, is
there documentation explaining how the “forecast horizon” is determined
and when it is updated?
Thank you.

Hey Im currently trying to use the weatherkit API and Im seeing the following returned:
{"reason": "OVER_QUOTA"}
Im using the correct service, key and bundle ID.
Ive generated a private key too.
I use WeatherKit with Swift to get multiple cities weather by longitude and latitude.
But I use this API in WeatherService for daily forecast:
final public func weather<T>(for location: CLLocation, including dataSet: WeatherQuery<T>) async throws -> T
And I found there is something wired: The date of WeatherKit::DayWeather is based on my device's timezone settings.
Tokyo's Day Weather is start at UTC+8, New York' Day Weather is start UTC+8.
Is there any way to set timezone correctly?
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).
Hi everyone,
I'm working on an app for parents and kids where parents can define screen time goals or restrict usage of certain app categories (like social media or games). If the kid follows those rules—for example, by using their device less or avoiding restricted categories—they would earn points or rewards in the app.
I’ve been exploring if the Apple Screen Time API allows developers to access this kind of data (like total screen time, app usage by category, etc.) so that I can track the kid’s behavior and reward them accordingly.
Is it possible to programmatically access this data and implement such a reward system within my app? If so, what’s the best way to get started or which APIs should I look into?
Thanks in advance for your help!
Hello,
I’m currently reviewing and implementing age assurance and parental approval flows using AgeRangeService and PermissionKit (AskCenter) in the context of Texas regulatory compliance requirements.
While the high-level APIs are clear, there are several technical aspects where the intended usage patterns are not fully explicit in the documentation. Clarification on these points would help ensure our implementation aligns with system expectations and regulatory obligations.
⸻
Querying the current approval state for SignificantAppUpdateTopic
AskCenter.ask(...) returns Void, and AskCenter.responses(for:) provides an AsyncSequence of approval events.
Is there an official or recommended way to determine whether a SignificantAppUpdateTopic has already been approved when the app launches, or is listening for future responses events the only supported mechanism?
⸻
Behavior of AskCenter.responses(for:) regarding past approvals
When subscribing to AskCenter.responses(for:):
• Does the stream replay previously recorded approval or decline decisions?
• Or does it only emit events that occur after subscription?
This affects whether the listener must be registered early in the app lifecycle.
⸻
Recommended lifecycle timing for registering a responses(for:) listener
What is the intended or recommended time to register a responses(for:) listener?
• At application launch
• Immediately before calling ask(...)
• When entering a specific gated feature
Clarification on the expected lifecycle usage would be helpful.
⸻
Repeated calls to ask(...) after approval
If AskCenter.ask(...) is called again for the same SignificantAppUpdateTopic after parental approval has already been granted:
• Is the request ignored?
• Is a new approval request sent to the parent?
• Or is the call handled idempotently by the system?
⸻
Delivery of approval results when the child app is not running
If a parent approves or declines a SignificantAppUpdateTopic while the child app is not running:
• Will the approval decision be delivered as a responses(for:) event on the next app launch?
• Or is the app expected to persist approval state locally?
⸻
Persistence of approval state
Is the approval decision for SignificantAppUpdateTopic persisted by the system at the OS level, or is the app responsible for storing approval state?
Additionally, does the approval persist across:
• app restarts?
• app deletion and reinstallation?
⸻
Meaning of activeParentalControls.significantAppChangeApprovalRequired
How is activeParentalControls.significantAppChangeApprovalRequired determined?
• Is this value explicitly configured by a parent (for example via Screen Time)?
• Or is it automatically determined by the system based on region, age, or regulatory requirements?
⸻
Relationship between significantAppChangeApprovalRequired and AgeRangeService
When activeParentalControls contains significantAppChangeApprovalRequired, is it still expected that apps call AgeRangeService.requestAgeRange(...)?
Or can the presence of this flag be treated as sufficient indication that the user is a minor for gating purposes?
⸻
Recommended interpretation of AgeRangeDeclaration
Is the intended usage of AgeRangeDeclaration to handle each case individually, or is it acceptable and recommended to interpret the values as different trust levels (for example, self-declared vs. government ID or payment verified)?
Clarification on these points would help ensure that implementations of age assurance and parental approval flows are consistent with system behavior while meeting regulatory compliance requirements.
Thank you for your guidance.
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!
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 followed the method outlined in Apple's documentation to test "Revocation of Consent." Our server received the notification sent by Apple, but the parsed data only contains the following content (some data has been modified for privacy, but the fields remain unchanged):
{
"receiptType": "Sandbox",
"bundleId": "com.xxx.xxxxx",
"receiptCreationDate": 1764932591296,
"requestDate": 1764932591296,
"originalPurchaseDate": 1375340400000,
"originalApplicationVersion": "1.0",
"appTransactionId": "705020051250081000",
"originalPlatform": "iOS"
}
How can we identify that "a parent/guardian has revoked authorization for a specific user"? We are unable to determine which minor user should be restricted from using certain features of our app.
I hope to receive a prompt response from Apple's technical experts!
Thanks A Lot !

I’m trying to fully understand the purpose of the ageGates parameter in the AgeRangeService.requestAgeRange API.
The official documentation includes the following statement:
“The system may return geo-specific age ranges that override your provided age gates based on the person’s location and applicable regulations.
When geo-specific ranges are required, the returned age range reflects regulatory requirements rather than the bounds of your age gates.”
Based on this, it seems that even if my app provides specific age thresholds through the ageGates parameter,
the system may override those boundaries depending on regional laws or regulations, and return a completely different lowerBound / upperBound than what my age gates would suggest.
My current understanding is:
ageGates indicates the thresholds my app uses to define its internal feature tiers,
but the actual age range returned by the OS is determined by legal or regional requirements (e.g., COPPA, GDPR-K, AADC, SB2420),
meaning the returned age range may not align with the age ranges implied by my ageGates values.
I’d like to confirm whether this interpretation is correct.
Additionally, if different regions may produce different lowerBound / upperBound values due to regulatory requirements,
then it seems that:
developers shouldn’t rely on fixed age buckets, and
instead must implement feature gating logic dynamically based on whatever age range the OS returns.
So my questions are:
Is my understanding correct that ageGates is simply a hint that describes my app’s tier thresholds, and the OS may override those boundaries to comply with local regulations?
If lowerBound / upperBound can vary across regions, what is the recommended way for developers to design their feature-gating logic?
Should we avoid hardcoded age buckets and instead build flexible logic that adapts to whatever range the OS returns?
I’d appreciate clarification so I can design our age-based policies appropriately and in a regulation-compliant way.
Hi
We have an AppleTV app that is used to continuously display information (digital signage). One of our clients reports that their AppleTV returns to the homescreen by morning.
While our recommendation is to setup Mobile Device Management to lock the AppleTV into running only our app, not every client will have the IT knowledge to set this up. So we're trying to figure out possible causes for the app getting closed.
We've not received any crash reports, nor does the device give any indication the app crashed.
The energy saving settings are set to run continuously without sleep.
The client is reporting this happens every night, so it seems unlikely to be caused by tvOS updates.
Are there other things I could rule out to find the cause of this issue? Any ideas are welcome, thanks!

How can I use the Screen Time API to set a restriction for a child account from my app running on the parent’s account?
Is there any way to use blockedApplications to hide all apps in a category? Currently, I use blockedApplications to hide individual apps, but it doesn’t work when I select an entire category. I thought the only solution would be to use shield, which doesn’t hide the apps but creates a blocking shield.
However, I found an app on the App Store called Fokus, and it’s able to select a category and block all the apps in it. Does anyone know how this could be possible?
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!
Hi,
I developed an iOS app which will do SMS filtering by following this documentation. https://developer.apple.com/documentation/identitylookup/sms-and-mms-message-filtering)
I built the app and send Test Flights to different testers. All the Testers from Sri Lanka (an asian country) says filtering is working and they can see all the enabled categories on the Messages too (including iOS 26). But the testers from Mexico cannot see the categories and filtering is not working.
On official documentation there is nothing about supported countries. But I found true caller article https://support.truecaller.com/support/solutions/articles/81000406341-how-do-i-enable-sms-filtering-on-iphone mentioning it support only few countries for SMS filtering.
Currently available in the following countries: India, Nigeria, South Africa, Kenya, Bangladesh, Sri Lanka.
Our previous Categories filtering are still available for: Australia, Bahrain, Canada, Ghana, Tanzania, United Kingdom, United Arab Emirates, United States of America, Zambia
Following article https://clearstream.io/blog/ios-26-iphone-new-text-message-filtering is saying some categories are supported by only Brazil and India.
Still I could not find any official documentations saying different country supports.
Hi Apple Dev community,
I want to ask if CallKit and CXCallDirectoryProvider (with addBlockingEntryWithNextSequentialPhoneNumber) doesn't work for 3rd party Phone apps.
Is this a known issue that CallKit doesn't work on 3rd party iOS Phone apps (like WhatsApp, etc)?
Thank you.
Hello,
I have noticed that the ShieldConfiguration is only requested when opening a target app, and never when the application token is moved to a different shield while the target app remains in foreground.
This causes problems because many times the wrong ShieldConfiguration is displayed (recycled) instead of requesting a new ShieldConfiguration.
This bug has been around since the introduction of the Screen Time API in 2020 and is has not been addressed.
Bug reports:
FB14237883
FB17902392
Please fix asap!! Not acceptable to have bugs not being addressed for more than 5 years.
Most concerning: This is still reproducing on iOS 26 beta 7!!
Thanks a lot for your help.

Hello,
I’m developing an app to detect movement past a strong magnet, targeting both Android and iOS. On Android, I’m using the Sensor API, which provides calibrated readings with temperature compensation, factory (or online) soft-iron calibration, and online hard-iron calibration. The equivalent on iOS appears to be the CMCalibratedMagneticField data from the CoreMotion framework.
However, I’m encountering an issue with the iOS implementation. The magnetometer data on iOS behaves erratically compared to Android. While Android produces perfectly symmetric peaks, iOS shows visual peaks that report double the magnetic field strength. Additionally, there’s a "pendulum" effect: the field strength rises, drops rapidly, rises again to form a "double peak" structure, and takes a while to return to the local Earth magnetic field average. The peaks on iOS are also asymmetric.
I’m wondering if this could be due to sensor fusion algorithms applied by iOS, which might affect the CMCalibratedMagneticField data. Are there other potential reasons for this behavior? Any insights or suggestions would be greatly appreciated.
Thank you!
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)
