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.

From https://developer.apple.com/forums/thread/803945?answerId=862153022#862153022, the testing of Age Range API was not available through xcode simulator back in Oct 2025.
Is this available now? In particular:
Is requestAgeRange testing available through simulator?
Is requestAgeRange testing with sandbox account available through simulator?
Is isEligibleForAgeFeatures available through simulator?
Is isEligibleForAgeFeatures testing with sandbox account available through simulator?
If the answer is "yes" to any of the above, which version of the xcode and ios version should I use?
So far I didn't get any of the above working on the simulator, and I can't find any documentation on the answers above.
Thank you!
As discussed and acknowledged here, there is a known bug with the FamilyActivityPicker. When a user expands a category that contains enough tokens to exceed the 50mb memory limit, the FamilyActivityPicker crashes.
This happens quite frequently for heavy Safari users. An apple engineer mentioned on this thread that WebDomains shown in the picker are present based on the last 30 days of usage data as surfaced by WebKit.
Is there any way a user can clear these WebDomains? Either programatically through our app or any other process we can guide them to as a workaround while this issue is getting fixed?

Hi,
I'm currently working on an app made originally for iOS 15. On it, I add an observer on viewDidLoad function of my ViewController to listen for changes on the UserDefault values for connection settings.
NotificationCenter.default.addObserver(self, selector: #selector(settingsChanged), name: UserDefaults.didChangeNotification, object: nil)
Said values can only be modified on the app's section from System Settings.
Thing is, up to iOS 17, the notification fired as expected, but starting from iOS 18, the notification doesn't seem to be sent by the OS.
Is there anything I should change in my observer, or any other technique to listen for the describe event?
Thanks in advance.
I'm using the new AlarmKit framework to schedule and trigger alarms in my Swift app in iOS 26 beta 4 (23A5297i).
I'm trying to customize the alarm sound using a sound file embedded in the app bundle or by referencing known system tones.
Problem:
No matter what I pass to .named("sound-2"), whether a file bundle url, .named("sound-2.caf"), tried .mp3, .caf & .aiff, or a known iOS system sound like .named("Radar") ("Chimes", etc.), the alarm always plays the default system alert tone. There's no error or warning, but the custom or specified sound is silently ignored.
sound: .named("sound-2")
Question:
What is the correct method or approach to play custom sound / music when Alarm Triggers?
What .named("...") expects file name, file Path URL or System sound name?
Is there any specific audio file length accepted or specific format?
Challenge:
The alarm functionality feels incomplete without support for custom sounds. A single default alert tone is often not sufficient to wake up users effectively. Hope it will be fixed in the next iOS updates.

I experimented a lot with Live Caller ID when it first appeared with iOS 18 Beta.
Now I'm starting to pick it up again and have immediately noticed some detrimental differences between the behavior observed when it was in beta status to how it currently behaves with iOS 18.3.
The main difference is caching - if a call is made and data from a live call id lookup displayed on the call screen, then if the call is made again immediately then that data is re-fetched from the server.
And it takes a long time too, about 5 or 6 seconds before the data is displayed in the call screen (with the beta it took about 3 seconds).
In the data set cache_expiry_minutes is set to 50, yet it's not being honored, there's no caching occurring at all. Yet this did used to occur several months ago when the feature was in beta.
What's happened to caching, why is it no longer working when it used to?
Another change is there used to be a notification displayed when a call was blocked, this no longer is displayed.
Is this an intentional change or a bug?
Hi All, I’m puzzled by this issue: my app uses WeatherKit to fetch hourly UV-index and temperature forecasts. The same build, running on the latest iOS, succeeds on most devices but consistently fails on a few. Strangely, the paired Apple Watch version retrieves the data without problems. Could WeatherKit be applying per-user throttling? Any insight would be greatly appreciated.
How to programmatically check if ApplicationToken or ActivityCategoryToken is expired in FamilyActivityPicker?
I'm building a Screen Time-based parental control app using FamilyControls and ManagedSettings. We use FamilyActivityPicker to allow the user to select apps and categories to restrict, and we apply the shield using:
store.shield.applications = .specific(selection.applicationTokens)
store.shield.applicationCategories = .specific(selection.categoryTokens)
Sometimes, we observe that the shield silently fails to apply — no error is thrown, but the restrictions aren't enforced. I suspect this may be due to expired or invalid tokens, possibly if the app was removed or the selection became stale.
My Questions:
Can ApplicationToken or ActivityCategoryToken expire or become invalid over time?
If yes, is there a supported or recommended way to detect whether a token is still valid before applying it to the shield?
Is comparing the current shield values (store.shield.applications and store.shield.applicationCategories) after applying them a reliable validation method?
What's the best practice to handle expired tokens (e.g. re-prompt the FamilyActivityPicker, or show a fallback)?
What Is the Expiration Duration of Tokens from FamilyActivityPicker?
Any guidance or insight from the Screen Time/FamilyControls team would be greatly appreciated!
Thank you!
We have an application which is written in Swift, which activates Transparent Proxy network extension. We are using Jamf MDM profile for deployment.
To avoid the user deleting / disabling the extension from General -> LogIn Items & Extension -> Network Extensions screen, we are using "Non-removable system extensions from UI" attribute under Allowed System Extensions and Teams IDs section.
In new Mac OS 26 (Tahoe), user can also enable/disable the extension from General -> LogIn Items & Extension -> Apps tab. The "Non-removable system extensions from UI" attribute set in Jamf MDM profile does not apply to this tab.
Same attribute is working for General -> LogIn Items & Extension -> Extensions tab and there the slider is greyed out and Remove option is not available under more menu.
Is there any new key/configuration defined to disable the slider from General -> LogIn Items & Extension -> Apps tab?

Given that iOS 18.2 is out and following documentation and WWDC example (limited to iOS 18.2+), I am attempting to use @AssistantIntent(schema: .system.search) along an AppIntent.
Questions:
Has anyone made this to work on a real device?!
In my case (code below): when I run the intent from Shortcuts or Siri, it does NOT open the App but only calls the perform method (and the App is not foregrounded) -- changing openAppWhenRun has no effect! Strangely: If my App was backgrounded before invocation and I foreground it after, it has navigated to Search but just not foregrounded the App!
Am I doing anything wrong? (adding @Parameter etc doesn't change anything).
Where is the intelligence here? The criteria parameter can NOT be used in the Siri phrase -- build error if you try that since only AppEntity/AppEnum is permitted as variable in Siri phrase but not a StringSearchCriteria.
Said otherwise: What's the gain in using @AssistantIntent(schema: .system.search) vs a regular AppIntent in this case?!
Some code:
@available(iOS 18.2, *)
@AssistantIntent(schema: .system.search)
struct MySearchIntent: ShowInAppSearchResultsIntent {
static let searchScopes: [StringSearchScope] = [.general]
static let openAppWhenRun = true
var criteria: StringSearchCriteria
@MainActor
func perform() async throws -> some IntentResult {
NavigationHandler().to(.search(.init(query: criteria.term)), from: .siri)
return .result()
}
}
Along with this ShortCut in AppShortcutsProvider:
AppShortcut(
intent: MySearchIntent(),
phrases: [
"Search \(.applicationName)"
],
shortTitle: "Search",
systemImageName: "magnifyingglass"
)

Apple Intelligence
i have iPhone 16 pro and I’ve updated to IOS 18.2.
however after I clicked on ‘Get Apple Intelligence’, and then set up button, nothing happened. I’ve tried this process many times still nothing working.
I put a test.mp3 (30 sec) file into the App Bundle.
I scheduled an AlarmKit alarm with the file name test.mp3.
The custom sound plays ✅
I copied the file from the App Bundle to Library/Sounds/test2.mp3.
I scheduled an AlarmKit alarm with the file name test2.mp3.
Instead of playing the custom sound, it falls back to the default sound ❌
According to the documentation, sounds placed in Library/Sounds should be playable:
I filed report FB19779004 on August 20, but haven’t received any response yet.
This functionality is critical for our use case, so could you please let me know whether this is expected to be fixed soon, or if I’m misunderstanding the intended behavior?

In iOS 18, the requestValue method no longer works when the parameter it is called on is not included in the parameterSummary of an AppIntent. This issue causes the app to fail to present a prompt for the user to select a value, resulting in an error with the message:
Domain=NSCocoaErrorDomain Code=4099 "The connection from pid 40685 on anonymousListener or serviceListener was interrupted, but the message was sent over an additional proxy and therefore this proxy has become invalid."
Steps to Reproduce:
Create a simple AppIntent with the following code:
import AppIntents
struct Intent: AppIntent {
static let title: LocalizedStringResource = "Intent"
static var parameterSummary: some ParameterSummary {
Summary("Test \(\.$category)") {}
}
@Parameter(title: "Category")
private var category: CategoryEntity?
@Parameter(title: "Hidden Category")
private var hidden: CategoryEntity?
@MainActor
func perform() async throws -> some ReturnsValue<CategoryEntity?> {
var result: CategoryEntity?
do {
result = try await $hidden.requestValue("Select category") // Doesn't work since iOS 18 as $hidden is not set in parameterSummary
} catch {
print("\(error)")
}
return .result(value: result)
}
}
Run the code on a device with iOS 18.
Observe that the requestValue method fails to present the selection prompt and instead throws an error.
Expected Results:
The app should successfully present a prompt for the user to select a value for the hidden parameter using requestValue, even if the parameter is not included in the parameterSummary.
Actual Results:
The app fails to present the selection prompt and throws an error, making it impossible to use requestValue for parameters not included in parameterSummary.
Version/Build:
iOS 18.0
Configuration:
Tested on various devices running iOS 18.
Is there a change in the API that I might have missed?
We first discovered this issue in our own product, but we were able to reproduce it even when using Apple’s official demo:
https://developer.apple.com/documentation/alarmkit/scheduling-an-alarm-with-alarmkit
Reproduction Steps:
Set an alarm on iOS 26.1 using AlarmKit.
Upgrade the device to iOS 26.2 beta 3 or later.
The alarm will no longer ring.
Based on our testing, versions prior to 26.2 beta 2 do not exhibit this issue, so it appears that something introduced in beta 3 has caused the regression.
The results are as follows:
iOS 26.1 → iOS 26.2 beta 2 or earlier: Alarms ring normally
iOS 26.1 / iOS 26.2 beta 2 → iOS 26.2 beta 3 / iOS 26.2 RC: Alarms fail to ring
iOS 26.2 beta 3 → iOS 26.2 RC: Alarms ring normally
This issue is critical. Users currently on iOS 26.1 may experience alarms failing to ring after updating their system, which can cause real-life disruptions (e.g., being late for work). We strongly recommend addressing this as soon as possible.

My scenario is to help users set up a full year's alarms at once. The dates for the alarms follow a specific pattern, but not fixed weekdays, so the fixed-date type is needed.

Hello, I have an AppClip technical issue I'd like to ask about:
Our Xiaohongshu App (Version 9.14 & Build 9140845 & appid 741292507) was submitted to the App Store for review on December 18th and approved on December 19th, starting a phased rollout.
This version was the first to support AppClip functionality, and as of today the app has been fully rolled out, but I still cannot activate the Xiaohongshu App Clip Card using the NFC tag (built-in URL: https://xhslink.com/n/22UG9jlaOfv?sourceid=911).
I checked all the configurations of our project's AppClip target (Associated Domains:appclips:xhslink.com), the default experience in the ASC backend (URL: https://appclip.apple.com/id?p=com.xingin.discover.Clip), and the advanced experience (URL: https://xhslink.com/n/Arxpo4IVY9X), and all showed no abnormalities.
Furthermore, the default experience URL, after being written with an NFC tag, can be successfully launched by tapping the NFC tag to open the Xiaohongshu App Clip Card, and the Card can also be opened normally in Safari on the phone.
However, our advanced experience URL, after being written with an NFC tag, cannot be launched by tapping the Card.
Therefore, my question is: Who please can help me check why the Xiaohongshu App Clip Card cannot be launched normally using the advanced experience URL? Thank you very much!
My Expectations: My advanced experience URL configured on the ASC platform, such as https://xhslink.com/n/Arxpo4IVY9X, should be recognized and validated by the iOS system when the phone is near the NFC tag and reads https://xhslink.com/n/22UG9jlaOfv?sourceid=911, ultimately triggering the App Clip Card configured in Xiaohongshu's advanced experience settings.
Additionally: We have already deployed a large number of NFC tags and other materials in many online stores, and the URL (https://xhslink.com/n/Arxpo4IVY9X) is built-in, and our 9.14 version is fully implemented. However, the newly developed App Clip feature is not working, which is very urgent and I hope Apple can help me find the cause of the problem and how to improve it as soon as possible. Thank you very much!
We recently released an update to our app to prepare for TX SB2420.
Almost immediately on release, we started getting crash reports of crashes when calling isEligibleForAgeFeatures.
Crashed: com.apple.root.user-initiated-qos.cooperative
EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000004
Is it possible that these are beta users that have IOS 26.2 RC or is there a bug in the release version of IOS 26.2?
Note: The crash reports are coming from Crashlytics so we are not getting OS build identifiers other than version "26.2"
There is an inconsistent issue when views are rendered from the Device Activity Report Extension. This issue is noticeable only on release versions and it works fine in debug mode.
Around 80% of the times, the Report Views return blank screen and this is only the case when a weekly/monthly filter is used. Although, it works as expected for daily report views.
My questions are:
How are all the Report Activity Views working fine in debug mode but not in release mode?
How the daily activity filter works fine in the release mode but the weekly/monthly filters don't work? Is this because of a memory limit issue in the extension?
As of now, I have the family-controls(distribution) entitlement only for the app and for the extensions I only have family-controls(development) entitlement. Do I need to request for family-controls(Distribution) entitlement even for the extensions?
I have seen threads on the forum mentioning the blank screen issue associated with the DeviceActivityReport but haven't found a solution to it. Any suggestions/feedback would be of great help, 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?
