I’m developing a self-management app using Family Controls, but I’ve encountered a FamilyActivityPciker's crash due to an XPC(or UIRemoteView) issue when there are too many tokens(maybe 200+ items) in a category. This makes bad UX, so I’m looking for a workaround.
(I guess that the crash reason is cross process memory limitations, such as App Extension 50MB memory limitation.)
A lot of web domains contribute to increase the number of tokens, However, even after clearing Safari’s browsing history, the tokens displayed in the FamilyActivityPicker remains unchanged.
Is there any workaround that a 3rd party developer can implement to address this issue? prevent FamilyActivityPicker crashes or reduce the number of web domain tokens?
For example, if there’s a way to reset the web domain tokens shown in FamilyActivityPicker from the Settings app, I could offer a help to users.
Does anybody have ideas?
Expanding SNS Category (29 items)
It succeeded.
Expanding Productivity & Finance (214 items)
It failed. The screen froze, then appears blank. When the number of items is around 100, the crash rate is 50%, but when the items are over 200, the crash rate is 100%.
Search Bar Problem
The search bar also has same problem. If the number of search results are small, it works good without any blank, but if there are a lot of search results (200+), the XCP crashes and the screen appears blank.
Code to Reproduce
import SwiftUI
import FamilyControls
struct ContentView: View {
@State private var selection = FamilyActivitySelection()
@State private var isPickerPresented: Bool = false
var body: some View {
VStack {
Button("Open Picker") {
isPickerPresented = true
}
}
.familyActivityPicker(isPresented: $isPickerPresented, selection: $selection)
}
}
Steps to Reproduce
Prepare a category that has 200+ items
Try to open the category in the picker
The screen will freeze, then appears blank.

I've been stuck for days trying to figure out how to extract the full text of a Siri prompt that launches my app. We need to be able to get the text of the full command, such as "Hey siri, buy dogfood...." so I can get "dogfood" or anything else following 'buy' . The examples I am finding are a) out of date or b) incomplelete. Right now we're using AppIntents with Shortcuts, but have to use dedicated shortcuts for each specific purchase, which are obviously very limiting.
I have been struggling with getting accurate data from the weatherkit api. It tends to be just different enough from the weather app on the phone.
While debugging this I randomly added forecastNextHour to my dataset string and it suddenly made everything match the app and the data looked good.
For example there is at this moment a snow storm in Billings. This url:
https://weatherkit.apple.com/api/v1/weather/en-US/45.79/-108.50?dataSets=currentWeather,forecastHourly,forecastNextHour&timezone=America/Denver&country=US
says that there is heavy snow, and there is a 100% chance for the next few hours. This matches the iOS app.
This url without forecastNextHour:
https://weatherkit.apple.com/api/v1/weather/en-US/45.79/-108.50?dataSets=currentWeather,forecastHourly&timezone=America/Denver&country=US
Says it is hazy and there is a small chance of snow of snow for the next few hours. Like 20-30 percent. This does not match any weather data I can find.
I have even checked the forecastStart times and the current weather asOf time. They all match up and are accurate.
Is there some unknown reason that without forecastNextHour the API becomes inaccurate?
Thanks!
Hi there
The behaviour of using Locale(identifier: "ar") with NumberFormatter.locale appears to have changed between iOS 17 and iOS 18.
Is this expected?
Steps to reproduce
import UIKit
func numberFormatter(withlocaleString localeString: String) -&gt; NumberFormatter {
let locale = Locale(identifier: localeString)
let numberFormatter = NumberFormatter()
numberFormatter.locale = locale
return numberFormatter
}
let numbers = 0...9
let localeDigits = numbers
let ar_digits = localeDigits.compactMap {
numberFormatter(withlocaleString: "ar").string(for: $0)?.first
}
print(ar_digits)
Results
The results show:
**** numbering system on iOS 17
latn numbering system on iOS 18.
iOS
Output
iOS 17
["٠", "١", "٢", "٣", "٤", "٥", "٦", "٧", "٨", "٩"]
iOS 18
["0", "1", "2", "3", "4", "5", "6", "7", "8", "9"]
Hello Apple development team, I have developed an App for screen time management, which mainly uses ScreenTimeAPI. Users can set certain Apps to be disabled during a certain period of time.
After the App is released, users often report that the settings do not take effect as expected. I have seen many developers on the forum reporting that the DeviceActivityMonitor extension sometimes does not trigger callbacks. Based on this background, I have the following questions:
Is it a known problem that the DeviceActivityMonitor extension sometimes does not trigger callbacks? If so, are there any means to avoid or reduce the probability of occurrence?
In addition to being killed by the system when the running memory exceeds (I just called some ScreenTimeAPI and accessed UserDefaults in the extension, which should not exceed the running memory), under what other circumstances will the DeviceActivityMonitor extension be killed by the system? Will it automatically recover after being killed? Will some callbacks be called when killing?
Does ManagedSettingsStore have a life cycle? How do you avoid conflicts when configuring the underlying operating mechanism of multiple stores?
This is a random problem. I have never encountered it during development and debugging, but users often report it.
thanks

Use case: When users open any URL in iOS Safari and tap the share button, the share extension can automatically receive the PDF version of the webpage from Safari.
We've observed that the system Markup app and the Apple Books app can automatically receive a PDF file from Safari. However, our custom share extension only receives the webpage URL.
While iOS Safari provides an "Options" button to manually share a webpage as a PDF, this feature is not intuitive and requires user education.
Could someone help to identify the correct NSExtensionActivationRule (or any other solution) that would allow our share extension to directly receive the PDF snapshot from Safari without requiring additional user actions?
Hi Apple Developers,
I am currently working on a message filtering application and facing issues specifically with filtering RCS (Rich Communication Services) messages. To debug this, I created a sample app that consistently categorizes all incoming messages as "junk." However, the filtering behaviour is inconsistent and not functioning as expected.
Here are the key issues observed during testing on iOS versions 18.2.1 and 18.3:
Inconsistent Filtering Behavior:
When a message is received from an unknown number, it sometimes gets moved to the Junk folder momentarily but is then immediately moved back to the main Messages inbox.
In some cases, the message does not get moved to the Junk folder at all, despite the app returning the verdict as "junk."
Duplicate Contact Tiles:
The Messages app displays two separate conversation tiles for the same mobile number, which is unexpected behavior.
For reference, my carrier partner is T-Mobile. Please let me know if you need any additional information to investigate this issue further.
Looking forward to your insights and guidance.
Best regards,
Rijul Singhal
I have a home widget with buttons (new in iOS 17).
In order to prevent taking action if the user taps on the widget buttons accidentally, I want to ask the user for confirmation.
It appeared that requestConfirmation be exactly what I needed, but no confirmation view shows up when I invoke this method in the perform function.
I have tried the following:
try await requestConfirmation(result: .result(dialog: "Are you sure you want to do this?") {
Image(.mdlsWhite)
})
and this alternative:
let confirmed: Bool = try await $name.requestConfirmation(for: self.name,
dialog: IntentDialog(stringLiteral: msg))
Neither option work.
I am starting to think that the requestConfirmation is not to be used with Home Widgets.
Is there a better way to handle confirmations for buttons included in a Home Widget?
Is there a way to distinguish physical mouse/keyboard input from remote control mouse/keyboard input on Mac? Or even better, is there a way to detect if my Mac is being remotely controlled?
I'm using react native with expo, firebase for auth, and I have google, facebook and Apple Sign In enabled. On my IOS simulator I can sign in using all 3 with no problems, but when I build and submit to test flight and test on a real device only google sign in works
It crashes when I try to sign in with facebook and I get an error saying The operation couldn't be completed. (com.apple.AuthenticationServices.AuthorizationError error 1000.)

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?

Hi developers,
I have a question if it is possible to open in my application not main window but a specific ViewController, when application is installed but not running.
When the application is running in background and I scan QR code, then specific ViewController is opened over SceneDelegate and method 'userActivity'. But this does not work when the application is only installed, but not running.
The Appstore link is here: https://apps.apple.com/us/app/don%C3%A1tor/id6473955033
I rarely use the Shortcuts app, so it took me a while to notice that my app's app intents all show incorrectly on macOS 15. On macOS 14 and 13, they used to show correctly, but now it seems that all localized strings show the key rather than the localized value.
@available(iOS 16.0, macOS 13.0, *)
struct MyAppIntent: AppIntent {
static let title = LocalizedStringResource("key1", comment: "")
static let description = IntentDescription(LocalizedStringResource("key2", comment: ""))
...
}
In Localizable.xcstrings file I have defined all the strings, for instance I have associated key1 with the value Title, but while the Shortcuts app used to display Title, it now displays key1.
Is this a known issue or did something change in macOS 15 that would require me to update something?
I have a very basic App Intent extension in my macOS app that does nothing than accepting two parameters, but running it in Shortcuts always produces the error "The action “Compare” could not run because an internal error occurred.".
What am I doing wrong?
struct CompareIntent: AppIntent {
static let title = LocalizedStringResource("intent.compare.title")
static let description = IntentDescription("intent.compare.description")
static let openAppWhenRun = true
@Parameter(title: "intent.compare.parameter.original")
var original: String
@Parameter(title: "intent.compare.parameter.modified")
var modified: String
func perform() async throws -> some IntentResult {
return .result()
}
}
The App has the ability to use WebKit and display web pages and the ability to add phone numbers to CallDirectory at specific timing.
In this App, when the App is launched or when the Add Contact button on the web page is pressed,
CallDirectoryExtention is reloaded from the host app (WebKit-viewController), the phone number is retrieved from the server, and the entry is updated.
I would like to add a process to remove the already added phone number entry when a specific value is retrieved from the application server.
The specific process we wish to implement is as follows.
Step 1: Use URLsession to retrieve values from the application server. (ViewController)
Step 2: If the value is a specific value, call a Function that deletes the CallDirectoryExtention entry. (ViewController)
Step 3: Delete all entries for the registered phone numbers.
However, I am aware that I have to use reloadExtension() to call the CallDirectoryExtention process from ViewController on Step2.
if I do so, CallDirectoryHandler.beginRequest() will be processed, and I am wondering if it is not possible to execute only the Function that deletes the entry.
Is there a way to run only the Function that deletes the CallDirectoryExtention entry from the host app(viewController)?
On my MAC, I have a XPC server running as a daemon. It also checks the clients for codesigning requirements.
I have multiple clients(2 or more).
Each of these clients periodically(say 5 seconds) poll the XPC server to ask for a particular data.
I want to understand how the performance of my MAC will be affected when multiple XPC clients keep polling a XPC server.
Some time ago I read somewhere that one can get a file icon on iOS like this:
UIDocumentInteractionController(url: url).icons.last!)
but this always returns the following image for every file:
Today I tried the following, which always returns nil:
(try? url.resourceValues(forKeys: [.effectiveIconKey]))?.allValues[.effectiveIconKey] as? UIImage
Is there any way to get a file icon on iOS?
You can try the above methods in this sample app:
struct ContentView: View {
@State private var isPresentingFilePicker = false
@State private var url: URL?
var body: some View {
VStack {
Button("Open") {
isPresentingFilePicker = true
}
if let url = url {
Image(uiImage: UIDocumentInteractionController(url: url).icons.last!)
if let image = (try? url.resourceValues(forKeys: [.effectiveIconKey]))?.allValues[.effectiveIconKey] as? UIImage {
Image(uiImage: image)
} else {
Text("none")
}
}
}
.padding()
.fileImporter(isPresented: $isPresentingFilePicker, allowedContentTypes: [.data]) { result in
do {
let url = try result.get()
if url.startAccessingSecurityScopedResource() {
self.url = url
}
} catch {
preconditionFailure(error.localizedDescription)
}
}
}
}
we have three problem when using the push notification on Live Activity.
1. What is the specific callback strategy for the activityUpdates property in ActivityKit?
We found that in actual user scenarios, there is a probability that we may not receive callbacks. From the community experience, there are some resource optimization strategies that do not perform callbacks. From this perspective, the explanation is kind of vague. Is there any clear feedback to understand why callbacks are performed/not performed?
2.what is the specific description of the wake-up strategy, when background app receive Live Activity offline start Push?
From community experience, we can see that the system may wake up for a duration of 0-30s due to resource optimization strategies, or not wake up/not deal with it. Is there an official description of the wake-up strategy? or we also have to follow this description:
Wake up of apps using content-available pushes are heavily throttled. You can expect 1-2 wakeup per hour as a best case scenario in the hands of your users. so this cannot be assumed to be a reliable wake-up on demand mechanism for an app.
3 How can we determine user have selected (allow or always allow) of the Live Activity permission?
When we use real-time activity offline push, there are two system prompts in iOS:
the first prompt : allow and disallow real-time activity
the second prompt : always allow and disallow
Is there an interface that can directly determine which permission the user has chosen (allow/always allow)? (By the way, we can get disallow status).
At present, we haven't seen any interface in the official documentation/interface that can determine (allow/always allow). The difference here will affect the generation of Update Token. Without Update Token, we can not update our activity instance.
