Hi,
I’m using a Local Push Connectivity Extension and encountering an issue with DispatchSourceTimer.
In my extension, I create a DispatchSourceTimer that is supposed to fire every 1 second. It works as expected at first. However, when the app is in the foreground and the device is locked, the timer eventually stops firing after 1–3 hours.
The extension process is still alive, and no errors are thrown
Has anyone experienced this behavior?
Is this a known limitation for timers inside NEAppPushProvider, or is the extension being deprioritized silently by the system?
Any insights or suggestions would be greatly appreciated.
Thanks!

I'm currently working on transitioning to StoreKit 2. In order to see if my users are legacy users who purchased the app before I implemented an in-app purchase, I am trying to use the original purchase date for the app. Unfortunately, it's returning 0 seconds since 1970.
func updateOriginalPurchaseStatus() async throws {
let transaction = try await checkVerified(AppTransaction.shared)
self.originalPurchaseVersion = transaction.originalAppVersion
self.originalPurchaseDate = transaction.originalPurchaseDate
}
This is from the transaction:
[3] = {
key = "originalPurchaseDate"
value = number (number = 0)
}
Currently trying to figure out when I actually purchased the app, but it might be as early as 2012. And I likely used a download code.
we’re looking to get some clarification around how the hourly forecasts should be interpreted to ensure we’re using your data in the correct manner. If you could provide the answers to the following questions would be extremely helpful:
1. What do the data points (e.g temperature) in the hourly forecast represent for a future hour? Do they represent the expected average over that future hour or do they represent the forecast for the point in time at the top of the hour?
2. What do those same data points represent in the hourly forecast for an hour which has already begun? e.g. it’s 8:30 and we pull the hourly forecast and the 8:00 hour is still returned. Which of the following would be the correct interpretation for the values returned for the 8:00 hour:
The values represent the forecast for the point in time at the top of the 8:00 hour (if this is the case we would expect it to stop updating)
The values represent the current forecast i.e. what the weather is right now
The values represent the average over the remaining portion of the 8:00 hour
The values represent the average over the full 8:00 hour including both the portion which has already elapsed and the portion which is still to come
3. What does the data represent after the hour (i.e. looking at historical hours)? Is it:
The last forecast made within the hour? If so, is that point-in-time or average for the hour (as explained above)?
The actual weather for that hour (using some non-forecast measure of real weather)? If so, again is that point-in-time at top of hour / point-in-time at end of hour / average over the hour?

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
I have an App Clip that uses SKOverlay.AppClipConfiguration to install the full app. Before I added a Live Activity call (Activity.request), the user could see “Install,” then “Open.” Now, once “Get” is tapped, the Clip immediately closes—no “Open” button appears. If I remove the Live Activity code, it works again.
I’ve confirmed that parent/child entitlements match, and tested via TestFlight. Is there a known issue or recommended workaround for combining SKOverlay + Live Activities in an App Clip so it doesn’t dismiss prematurely? Any insights are appreciated!
Note live activity is for App Clip only.
Today, I submitted the following proposal to Apple through the Feedback Assistant app. I'm not confident in how I phrased it—I'd appreciate any thoughts or feedback from fellow developers.
Proposal: "Apple Silicon.app" for macOS with Apple Silicon – Enhancing Performance and Swap Memory Control
This suggestion has been machine translated into English, so there may be some discrepancies.
If you need the actual text, please feel free to reply to this or ask at the email address below.
<mail address>
If the author of this proposal is to be credited, I would appreciate being listed under the nickname “DiamondGotCat,” where possible.
Summary:
- Currently, Apple Silicon-equipped Macs have many system-level features locked down or restricted.
- This proposal suggests a new application that enables certain advanced controls for power users.
- Tentatively named "Apple Silicon.app", the name may be subject to change if a more suitable alternative arises.
- I propose this application be added as a pre-installed utility on compatible systems:
macOS (M-series), iPadOS (A-series and M-series), and iOS (iPhones with Apple-designed A5 and newer chips, provided the latest OS is available for them).
Overview:
This proposal introduces "Apple Silicon.app", a new system-level utility designed to offer power users greater flexibility and control over Apple Silicon behavior, as part of a broader feature update for Apple devices.
I propose that Apple Silicon.app be automatically installed as a pre-installed application on Apple Silicon devices (Mac, iPad, iPhone, and select Vision devices) that support upcoming major system updates.
Suggested Features of Apple Silicon.app:
1. Performance Core Control
To describe this functionality, the following terminology will be used:
- P-cores: Performance cores
- E-cores: Efficiency cores
I understand that Apple Silicon emphasizes energy efficiency, but I believe there are users—myself included—who prioritize maximum performance regardless of power usage. Therefore, I propose that the app offer a drop-down menu with the following six modes for performance core usage:
A. Automatic (Recommended) – Default macOS behavior; automatically switches between P/E cores based on workload.
B. Performance Priority – Prioritizes P-cores for high-demand tasks, restricts E-cores. Ideal for developers, video editors.
C. Power Saving – Uses E-cores only whenever possible; limits P-core usage. Great for battery saving.
D. P-Core Exclusive Mode – User-defined processes always run on P-cores. Suitable for benchmarks or low-latency tasks.
E. E-Core Exclusive Mode – Prioritizes background tasks and thermal efficiency.
F. Manual Assignment (Advanced) – Users can manually assign P/E cores per application in a dedicated settings screen.
Additionally, I propose the following optional checkbox settings:
- Thermal Safety Mode: Automatically switches from P- to E-cores when system heat exceeds a threshold.
- Restore Core Settings on Wake: Remembers P/E settings after sleep/wake.
- Power Source Adaptive Mode: Switches to power-saving on battery, and performance mode when plugged in.
2. Swap Memory Configuration
The app should also enable user-level control over swap memory (i.e., using part of the SSD as virtual memory).
Currently, macOS manages swap space automatically with no user customization available. I propose the ability to manually configure the swap system with the following options:
- Enable Manual Configuration: Checkbox to switch from automatic to manual control.
- Swap Size: Adjustable in GB units, allowing users to allocate desired swap capacity.
3. Other Settings
At this point, these are the core features I propose. If additional useful features exist that align with this concept, I welcome further suggestions or expansion.
As users—at least speaking for myself—we look forward to such customization options becoming available.
Here is an AppleScript script to make it possible double-click files in Finder so that they will be opened in Vim, by Normen Hansen: https://github.com/normen/vim-macos-scripts/blob/master/open-file-in-vim.applescript (it must be used from Automator).
I try to simplify it and also to make it possible to use it without Automator. To use my own version, you only need to save it as application instead, like this:
osacompile -o open-with-vim.app open-with-vim.applescript
and then copy it to /Applications and set your .txt files to be opened using this app.
Here it is, it alsmost works:
-- https://github.com/normen/vim-macos-scripts/blob/master/open-file-in-vim.applescript
-- opens Vim with file or file list
-- sets current folder to parent folder of first file
on open theFiles
set command to {}
if input is null or input is {} or ((item 1 in input) as string) is "" then
-- no files, open vim without parameters
set end of command to "vim;exit"
else
set firstFile to (item 1 of theFiles) as string
tell application "Finder" to set pathFolderParent to quoted form of (POSIX path of ((folder of item firstFile) as string))
set end of command to "cd" & space & (pathFolderParent as string)
set end of command to ";hx" -- e.g. vi or any other command-line text editor
set fileList to {}
repeat with i from 1 to (theFiles count)
set end of fileList to space & quoted form of (POSIX path of (item i of theFiles as string))
end repeat
set end of command to (fileList as string)
set end of command to ";exit" -- if Terminal > Settings > Profiles > Shell > When the shell exits != Don't close the window
end if
set command to command as string
set myTab to null
tell application "Terminal"
if it is not running then
set myTab to (do script command in window 1)
else
set myTab to (do script command)
end if
activate
end tell
return
end open
The only problem is the if block in the very beginning:
if input is null or input is {} or ((item 1 in input) as string) is "" then
What is wrong here? How to make it work? (Assuming it already works fine if AppleScript is used using Automator.)

I set both production and sandbox App Store Notification server.
In sandbox, my server can receive all kinds of app store notification, including subscription and non-consumable in-app-purchase.
But in production, my server only receive subscription notification.
I can see some non-consumable in-app-purchase done in log, but the server didn't receive expected notification.
Anyone know why?
I really need the notification cause I need to know who made refund.
Hi, I want to offer an auto-renewable subscription (e.g., $1/month) that grants users (10 document analyses per month), with the count resetting at the start of each billing cycle.
-Unused analyses will not roll over to the next month-
Additionally, any analyses generated while the subscription is active will remain accessible to the user permanently, even if they cancel the subscription.
The paywall, app description, and metadata will clearly state that the subscription grants (10 document analyses per month with no rollover)
We want this to be implemented as an auto-renewable subscription model, not as a consumable service or a token/credit system (which we want to avoid).
Is this model acceptable under Apple’s guidelines, or would it be considered a token/credit system? Any insights or alternative suggestions would be appreciated.. Thanks
If I run an app with a message filter extension, it's triggered for all the prepaid unknown numbers and its not triggered for all the unknown postpaid numbers. Any idea, how to trigger for postpaid unknown numbers?.
I use Homepod Mini as the gateway and have bound 9 Matter lights and 7 Matter switches. Each of my switches has 12 buttons, and each button supports three functions: single click, double click, and long press. Therefore, a total of 252 actions can be configured for 7 * 12 * 3. Currently, a total of 71 actions are configured for the 7 Matter switches. When configuring the 72nd action, the app will prompt that the operation cannot be completed. But if you delete a few previously configured actions, such as 68 actions, then you can configure 3 more actions (69, 70, 71). However, as long as you configure the 72nd action, the app will prompt that the operation cannot be completed, as if the available space is occupied. What is the reason for this?

After copying and inserting instances I am getting strange duplicate values in arrays before saving.
My models:
@Model
class Car: Identifiable {
@Attribute(.unique)
var name: String
var carData: CarData
func copy() -> Car {
Car(
name: "temporaryNewName",
carData: carData
)
}
}
@Model
class CarData: Identifiable {
var id: UUID = UUID()
var featuresA: [Feature]
var featuresB: [Feature]
func copy() -> CarData {
CarData(
id: UUID(),
featuresA: featuresA,
featuresB: featuresB
)
}
}
@Model
class Feature: Identifiable {
@Attribute(.unique)
var id: Int
@Attribute(.unique)
var name: String
@Relationship(
deleteRule:.cascade,
inverse: \CarData.featuresA
)
private(set) var carDatasA: [CarData]?
@Relationship(
deleteRule:.cascade,
inverse: \CarData.featuresB
)
private(set) var carDatasB: [CarData]?
}
The Car instances are created and saved to SwiftData, after that in code:
var fetchDescriptor = FetchDescriptor<Car>(
predicate: #Predicate<Car> {
car in
car.name == name
}
)
let cars = try! modelContext.fetch(
fetchDescriptor
)
let car = cars.first!
print("car featuresA:", car.featuresA.map{$0.name}) //prints ["green"] - expected
let newCar = car.copy()
newCar.name = "Another car"
newcar.carData = car.carData.copy()
print("newCar featuresA:", newCar.featuresA.map{$0.name}) //prints ["green"] - expected
modelContext.insert(newCar)
print("newCar featuresA:", newCar.featuresA.map{$0.name}) //prints ["green", "green"] - UNEXPECTED!
/*some code planned here modifying newCar.featuresA, but they are wrong here causing issues,
for example finding first expected green value and removing it will still keep the unexpected duplicate
(unless iterating over all arrays to delete all unexpected duplicates - not optimal and sloooooow).*/
try! modelContext.save()
print("newCar featuresA:", newCar.featuresA.map{$0.name}) //prints ["green"] - self-auto-healed???
Tested on iOS 18.2 simulator and iOS 18.3.1 device. Minimum deployment target: iOS 17.4
The business logic is that new instances need to be created by copying and modifying previously created ones, but I would like to avoid saving before all instances are created, because saving after creating each instance separately takes too much time overall. (In real life scenario there are more than 10K objects with much more properties, updating just ~10 instances with saving takes around 1 minute on iPhone 16 Pro.)
Is this a bug, or how can I modify the code (without workarounds like deleting duplicate values) to not get duplicate values between insert() and save()?
I made a set of Siri Shortcuts in my app with the AppShortcutsProvider, and they each have a set of phrases.
I can activate the shortcuts via Siri phrases or Spotlight search on iOS 18+, but not on iOS -17.
I've checked the documentation and see that AppShortcutsProvider is supported from iOS 16+, so I don't understand why I can't view the shortcuts in Spotlight or activate them with Siri unless it's at least iOS 18.
Any thoughts?

Hi! I use Tips with CloudKit and it works very well, however when a user want to remove their data from CloudKit, how to do that?
In CoreData with CloudKit area, NSPersistentCloudKitContainer have purgeObjectsAndRecordsInZone to delete both local managed objects and CloudKit records, however there is no information about the TipKit deletion.
Does anyone know ideas?
Good day
We developed a simple swift code to make the device ringing when a certain type of notifications arrives from our backend. This is the code:
let phoneNumber = CXHandle(type: .generic, value: (self.userInfoForPluginCall!["data"] as! [String:Any]) ["caller"] as! String)
callUpdate.remoteHandle = phoneNumber
let configuration = CXProviderConfiguration(localizedName: "Trec Conf")
configuration.maximumCallGroups = 1
configuration.maximumCallsPerCallGroup = 1
configuration.supportsVideo = false
configuration.supportedHandleTypes = [.generic]
configuration.iconTemplateImageData = UIImage(named: "callkit-icon")?.pngData()
let callProvider = CXProvider(configuration: configuration)
callProvider.setDelegate(self, queue: nil)
callProvider.reportNewIncomingCall(with: callUUID!, update: callUpdate, completion: {error in})
We are noticing some problems on the call screen: on certain devices (iOS 18.4RC) the normal call screen appears and the user can answer or decline the call, on other devices (iOS 18.3, especially with dynamic island) only a phone icon appears in the upper right corner and no possibility to answer or deny call.
Any idea on why we are encountering that behavior?
Thanks

On iOS 18.3, I noted that partition "HTTPCookiePropertyKey: StoragePartition" is not observed to be set for cookies returned from the wkwebview cookie store.
Now on 18.4 beta 4 we are now seeing those same cookies are populated with a partition property. Is there documentation for this change? Is it intended to be suddenly populated in 18.4?
Now that partition property is set, HTTPCookieStorage.shared.cookies(for: serverUri) doesn't seem to return the expected cookies correctly. For context, we are using the cookies extracted from wkwebview, setting them in HTTPCookieStorage.shared and using URLSession to make network calls outside the webivew. Works fine once I forcefully set partition on the cookie to nil.
More details on what the cookie looks like here: https://feedbackassistant.apple.com/feedback/16906526
Hopefully this is on your radar?
