Hello,
I’m building an app that helps people spend less time on social media apps.
For that, I make heavy use of Apple’s Screen Time APIs, such as ManagedSettings and FamilyControls.
When an app is locked using a ShieldConfiguration, the user has to open my app in order to unlock it (e.g. enter a code).
This is very cumbersome because no documented API exists to open the parent app (=my app) from the ShieldActionDelegate (also part of my app) when the user presses a button of the ShieldConfiguration.
The ShieldActionDelegate callback just offers three options in its ShieldActionResponse:
.none
.defer
.close
.openParentApp is missing.
We are working around this limitation by sending a local push notification that the user has to tap on.
This has multiple drawbacks:
It has to be ensured that notification permission has been granted.
It has to be ensured that notifications can be delivered even while focus is enabled.
Features such as Apple Intelligence notification summaries and notification prioritization can heavily delay delivering notifications and thus frustrate the user.
Neither my users nor myself do understand why this is not possible in a smoother way, at least according to the documentation.
There are 3rd party apps that have such functionality, they can directly open their own app from a button press in the Shield, see here:
https://apps.apple.com/us/app/applocker-passcode-lock-apps/id1132845904
It would be great if Apple could level the playfield for all developers and document how this is achievable, because technically it clearly is.
Thanks a lot and have a great day!

When we compile our app using Xcode 26 and run it on iOS 26, we encounter a strange crash where the crashing thread shows no stack trace. After inspecting the registers, we have initially traced it to the Google Mobile Ads SDK. When we disable the initialization of the Google Mobile Ads SDK, the app no longer crashes.
However, running the Google Mobile Ads SDK demo app on iOS 26 alone does not cause any issues; the crash only occurs once it is integrated into our app. We also tried enabling Address Sanitizer and Zombie Objects but found no valuable clues.
Could you advise what other methods or tools we can use to further diagnose this issue? Additionally, when we compile the app with Xcode 15 and run it on iOS 26, everything works fine without crashes.

app packged with Xcode16 crashed on iOS12 certainly. My question is:
is it known issue for Apple team?
to resolve this issue, what can we developers do?
This is
We have a subscription WeatherKit app which has been on the App Store since December 2023.
I am getting intermittent JWT auth failures on customer devices. In the great majority of cases, the request succeeds, but sometimes it fails, and sometimes it fails and never recovers. I’m working with a customer right now who is unable to get any weather data at all, and the logs he sends me show
WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors error 2
The app uses the WeatherKit SDK (we are not using the REST API directly). We know we have the project setup as it has been working since launch, and I can verify weatherkit using
security cms -D -i embedded.mobileprovision
It it not a problem with the specific query, since I can get data for the dates and locations they are requesting. I can’t replicate the problem on my test devices.
In case there is a rate limit issue: this app is a bit unusual and downloads an unusual amount of data at once using multiple queries in parallel using a TaskGroup. When the user creates a location, the app downloads a 10 day block of weather (7 days in the past + 3 day forecast) using
WeatherService.shared.weather(
for: location,
including: WeatherQuery.daily(
startDate: startDate,
endDate: endDate
),
WeatherQuery.hourly(
startDate: startDate,
endDate: endDate
)
)
It also downloads about 2 months of daily precipitation data using multiple parallel calls to dailySummary in 10 day blocks:
WeatherService.shared.dailySummary(
for: location,
forDaysIn: DateInterval(start: startDate, end: endDate),
including: .precipitation
)
In almost every case, including on my test devices, this works. But some users get WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors error 2 on every request.
The two users yesterday that had this problem were both on iOS 18.5 for what that's worth, though the app supports 17.2+
Is anyone else seeing this? And can anyone suggest anything else to explore? It's obviously a terrible experience for customers who pay for the service and are unable to get any data.
I did submit this info to Apple as FB18276275
I created a ShieldConfigurationExtension in Xcode 14.3 with File > New > Target > ShieldConfigurationExtension. This created the extension with all the necessary Info.plist values (correct NSExtensionPrincipalClass, etc.), with the extension included in embedded content in the host app target.
No matter what I try, the extension is not getting invoked when I shield applications from my host app. The custom UI does not show as the shield, and looking at the debugger, an extension process is never invoked.
I am shielding categories like this:
let managedSettings = ManagedSettingsStore()
...
managedSettings.shield.applicationCategories = .all()
And my extension code overrides all the ShieldConfigurationDataSource functions.
class ShieldConfigurationExtension: ShieldConfigurationDataSource {
override func configuration(shielding application: Application) -> ShieldConfiguration {
return ShieldConfiguration(
backgroundBlurStyle: UIBlurEffect.Style.systemThickMaterial,
backgroundColor: UIColor.white,
icon: UIImage(systemName: "stopwatch"),
title: ShieldConfiguration.Label(text: "You are in a Present Session", color: .yellow)
)
}
override func configuration(shielding application: Application, in category: ActivityCategory) -> ShieldConfiguration {
return ShieldConfiguration(
backgroundBlurStyle: UIBlurEffect.Style.systemThickMaterial,
backgroundColor: UIColor.white,
icon: UIImage(systemName: "stopwatch"),
title: ShieldConfiguration.Label(text: "You are in a Present Session", color: .yellow)
)
}
override func configuration(shielding webDomain: WebDomain) -> ShieldConfiguration {
return ShieldConfiguration(
backgroundBlurStyle: UIBlurEffect.Style.systemThickMaterial,
backgroundColor: UIColor.white,
icon: UIImage(systemName: "stopwatch"),
title: ShieldConfiguration.Label(text: "You are in a Present Session", color: .yellow)
)
}
override func configuration(shielding webDomain: WebDomain, in category: ActivityCategory) -> ShieldConfiguration {
return ShieldConfiguration(
backgroundBlurStyle: UIBlurEffect.Style.systemThickMaterial,
backgroundColor: UIColor.white,
icon: UIImage(systemName: "stopwatch"),
title: ShieldConfiguration.Label(text: "You are in a Present Session", color: .yellow)
)
}
}
What am I missing?

A message filter extension is only forwarded SMSs by the OS for filtering, iMessages aren't.
But what is the situation with RCS messages? Will they be filterable by a message filtering extension?
I'm working on building a Text Messages Filter Extension app and currently facing the below error:
"Cannot find 'ILMessageFilterExtensionConfigurationManager' in scope".
As required the app includes MessageFilterStatusManager.swift file, with the host app designated as the Target Membership.
App minimum deployment is set to iOS 17.6 and I'm working with Xcode Version 26.2.
If anyone has encountered this error I'd appreciate your feedback.
I have made a screensaver for mac in swift, but couldn't find how to add an icon the logo image that shows up on saver file) and thumbnail (the cover image that shows up in the screensaver catalogue).
Currently, it just shows a default blue spiral galaxy thumbnail and no icon image
I have an app using weatherkit and its currently live and up on the app store, recently I had some users report to me that they had been receiving errors loading weather data, I had error handling built in and it reported an issue with apples authentication server
Failed to generate jwt token for: com.apple.weatherkit.authservice with error: Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)"
I have not come across this during the development lifecycle of my project, there where no codebase changes, it just stopped functioning.
The app entitlements are valid and correct, Weatherkit is enabled in both xcode and across my Certs, identifiers and profiles.
I was not experiencing this issue until I reinstalled the app from the app store completly by first removing it and then re-installing fresh.
Hard reboots do not help and I do not want to start suggesting to my users to factory reset their devices.
We are using WeatherKit in both our main app and widget, relying entirely on Apple’s framework for authentication and token management.
We do not generate or inject our own JWT tokens; all token handling is managed by WeatherKit.
We have implemented a debug menu with the following actions:
Clear WeatherKit JWT tokens from the keychain
Clear all related UserDefaults key
Clear all app group data and all UserDefaults.
Perform a “nuclear” cache clear (removes all app data, keychain, and cached files).
We log all WeatherKit fetch attempts and failures, including authentication errors, both in the app and widget and get nothing but code 2.
We have attempted all of the above steps, but continue to experience issues with WeatherKit JWT authentication
We would appreciate any guidance or insight into what else could be causing persistent WeatherKit JWT/authentication issues, or if there are any additional steps we should try.
P.S. - Tested and experiencing the same issues on an iPhone 15 Pro Max and iPhone 15
The Pro Max is on the iOS 26 Beta // and the 15 is on the latest iOS 18
From the Feb 24 news, I understand that for all Apple users in Brazil with iOS26.2 and newer, isEligibleForAgeFeatures will eventually return true. Brazil is a "nonregulated region", and developers will need to handle all three situations of ask first/always share/never share.
Please correct me if I'm wrong above. A few questions follow on the eligibility check:
What's the return value of IsEligibleForAgeFeatures for a Brazilian user who has NOT touched the age range feature at all, thus hasn't picked one of the three options?
How can we test these cases? From the updated sandbox doc, there's more information on declined/approved, will those the same behaviors as a future Brazilian user? The doc used to say Texas, now it doesn't say any region.
On which date will Apple START to return true for IsEligibleForAgeFeatures for Brazilian users? I cannot find the exact date anywhere.
Will ALL of Brazil return true overnight, or is there some ramp up that developers need to be aware of?
Thanks a lot for sharing the guidance, and thanks in advance for more guidance to come!
Hi everyone, on iOS, when a VoIP call arrives and the user accepts it from the lock screen (after unlocking with Face ID/Touch ID), is there any way to automatically bring my app to the foreground and show the in-app call screen, instead of staying in the system CallKit UI?
If an iPhone receives an incoming call with some partial sip content (for example it contains a name but not an image, or vice versa) and if there is an app enabled for Live Caller ID Lookup, and the result of that lookup supplies data not in the sip (i.e. the lookup returns an image, but not a name, or vice versa). Then could the OS combine data from both sources, or is whatever is returned from the LCIDL what gets displayed in the call screen. I suppose that is the case but just want to enquire to make sure.
Thank you
Hello,
I’m encountering an issue with Universal Links in my iOS app. After some investigation, I found that the root cause seems to be that Apple’s request through there CDN server to access the .well-known/apple-app-site-association file is blocked by our firewall, which enforces geographic access restrictions as part of our security policy.
Because of this restriction, Apple’s validation or link verification requests are being denied, and the Universal Links are not working as expected.
I’d like to get some guidance from the community or Apple engineers on the following:
1. Does Apple provide an official list of IP ranges or domains that need to be allowed through the firewall for Universal Link validation?
2. Are there alternative methods to handle Universal Link verification in environments with geographic restrictions?
3. Would whitelisting specific Apple services or endpoints be a recommended or safe solution?
Any input or recommendations would be greatly appreciated.
Environment Details:
• iOS app using Universal Links
• Server protected by a firewall with regional restrictions
• AASA file hosted correctly and accessible via browser
Thanks in advance for your help and insights.

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.
My ASA file is located here https://staging.docyt.com/apple-appsite-association It downloads fine. It does not have .json extension and neither does it reside inside the ./well-known folder. Should it work? Because opening the link https://staging.docyt.com/reset-password is not opening the app installed via TestFlight . Installing via XCode however works fine. Please help
My app AirCompare has been in the app store and successfully using WeatherKit to fetch weather since it became available. Now some (not all) users are encountering the following errors:

Subject: iOS Fails to Fetch AASA File for Internationalized Domain Names (IDN) in Unicode or Punycode Format
Dear Apple Developer Relations Team And Community Members,
We are reporting a critical bug in the iOS Associated Domains feature that prevents Universal Links from working for apps using Internationalized Domain Names (IDN).
Problem Description:
The iOS operating system does not attempt to download the apple-app-site-association (AASA) file for domains containing non-ASCII characters (e.g., diacritics, Cyrillic).
This failure occurs regardless of whether the domain is specified in the app's entitlements in its human-readable Unicode format (e.g., montréal.ca) or its encoded Punycode format (e.g., xn--montral-fya.ca, xn--e1afka0abm4b.xn--p1ai).
Without fetching and validating this file, Universal Links are not activated, and the system fails to establish a connection between the website and our app.
Steps to Reproduce:
Create an app with the Associated Domains entitlement enabled.
Add an IDN to the entitlement. We tested both formats:
Format A (Unicode): applinks://montréal.ca
Format B (Punycode): applinks://xn--montral-fya.ca
Host a valid AASA file on our server at the correct, accessible well-known URLs for both domain representations:
For montréal.ca: https://montréal.ca/.well-known/apple-app-site-association and https://xn--montral-fya.ca/.well-known/apple-app-site-association
Install the app on a device running the latest iOS version.
Monitor network traffic using a tool like Charles Proxy.
Observed Result:
No HTTP GET request is made to any of the AASA URLs for the domains montréal.ca (in either Unicode or Punycode format) upon app installation. The system does not initiate the domain validation process. In contrast, for a standard ASCII domain (e.g., applinks://example.com), the AASA fetch is triggered immediately and is observed in the network log.
Expected Result:
iOS should correctly resolve the Internationalized Domain Name (whether specified in Unicode or Punycode format in the entitlement) and perform an HTTP GET request to fetch the AASA file from the /.well-known path, identical to its behavior for ASCII domains.
Evidence & Configuration:
Our server is configured correctly: SSL certificates are valid, the AASA file is served with the correct application/json MIME type, and is directly accessible via a browser or curl.
The AASA file's syntax has been validated and is correct.
The issue is reproducible on the latest versions of iOS.
Impact:
This bug blocks a core platform feature for millions of users in regions that use non-Latin scripts (e.g., France, Russia, China, Arab states). It makes it impossible to use Universal Links with our primary domains, severely degrading the user experience and forcing us to seek suboptimal workarounds like registering separate ASCII domains.
Request:
We kindly request that you investigate and log this issue as a bug in iOS and forward it to the appropriate engineering team for a fix in an upcoming update. We are prepared to provide any additional information, demo projects, or server access to assist in diagnostics.
Thank you for your attention to this serious matter.
Hello,
In production, a large number of users experience outgoing call reporting fails with the following error:
com.apple.CallKit.error.requesttransaction Code=2
The iOS version doesn't matter, errors are present in v15-26
Details
My CXProvider held as a global singleton, so it’s unlikely to be deinited.
There is no explicit call to CXProvider.invalidate() in the app.
If I manually invalidate the CXProvider, I observe the expected failure when trying to create an outgoing call (com.apple.CallKit.error.requesttransaction error 2).
However, If I recreate the CXProvider after the error, outgoing calls are reported correctly.
Many users trigger the providerDidReset delegate method (CXProviderDelegate) before this error.
According to the documentation, providerDidReset can be called by the system, and we are supposed to end all active calls, but the documentation doesn't suggest recreating the CXProvider.
Question
Should I recreate CXProvider after providerDidReset and forget about that, or could this error be caused by something else?
I have installed the macOS 26 WWDC beta on a secondary volume, and set it up with two user accounts (both administrators).
However, the options for switching users without fully logging out are nowhere to be found.
The topic is still included in macOS Help and is shown when searching for “fast” in System Settings, however, the option is hidden/missing in the pref pane when selected.

Hello,
After being in the AppStore for more than a year with the app working perfectly, yesterday I started seeing that WeatherKit requests failed with
Failed to generate jwt token for: com.apple.weatherkit.authservice with error: Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)"
Encountered an error when fetching weather data subset; location=<+41.40217108,+2.20023642> +/- 0.00m (speed -1.00 mps / course -1.00) @ 13/12/25, 12:20:35 Central European Standard Time, error=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors 2 Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)"
I checked on developer.apple.com and we still have everything turned on and
No changes were made from an already deployed app; and we pay 200$ a month for WeatherKit, this is unacceptable since it's not the first time WeatherKit randomly decides to stop working.
More fun facts: the widget works fine...
