I've built an iOS & Watch OS app using Sign in with Apple & CloudKit exclusively.
I'm now wanting to implement Push Notifications. I understand that I need a server to trigger the push notifications (I guess I could spool up a Node server somewhere or use Firebase), but I'd really like to not use any non-Apple backend services.
Am I correct in understanding that I can do this with Push Notifications Console, or do I still need a separate backend?

I want to display device activity reports for particular selected apps. for getting a daily basis app uses time. Now, what is happening? there are 10 apps selected from the family activity picker but some apps are displayed in the list. I need all 10 apps or more that I will choose from the family activity picker. The bellow code is used for fetching reports.
var body: some View {
VStack {
DeviceActivityReport(context, filter: filter)
}
}
bellow code is used for the filter
@State public var filter = DeviceActivityFilter()
init(selectedApps: Set<ApplicationToken>, selectedCategories: Set<ActivityCategoryToken>, selectedWebDomains: Set<WebDomainToken>) {
self.selectedApps = selectedApps
self.selectedCategories = selectedCategories
self.selectedWebDomains = selectedWebDomains
self.filter = DeviceActivityFilter(
segment: .daily(
during: Calendar.current.dateInterval(
of: .weekOfYear, for: .now
)!
),
users: .all,
devices: .init([.iPhone]),
applications: selectedApps,
categories: selectedCategories,
webDomains: selectedWebDomains
)
}
You can see we selected 3 apps from family activity picker but we getting 2 apps from DeviceActivityReport extension
following code is for device activity report extension
let context: DeviceActivityReport.Context = .totalActivity
// Define the custom configuration and the resulting view for this report.
let content: (ActivityReport) -> TotalActivityView
func makeConfiguration(representing data: DeviceActivityResults<DeviceActivityData>) async -> ActivityReport {
// Reformat the data into a configuration that can be used to create
// the report's view.
var res = ""
var list: [AppDeviceActivity] = []
let totalActivityDuration = await data.flatMap { $0.activitySegments }.reduce(0, {
$0 + $1.totalActivityDuration
})
for await d in data {
res += d.user.appleID!.debugDescription
res += d.lastUpdatedDate.description
for await a in d.activitySegments{
res += a.totalActivityDuration.formatted()
for await c in a.categories {
for await ap in c.applications {
if let apptoken = ap.application.token {
let appName = (ap.application.localizedDisplayName ?? "nil")
let bundle = (ap.application.bundleIdentifier ?? "nil")
let duration = ap.totalActivityDuration
let numberOfPickups = ap.numberOfPickups
let app = AppDeviceActivity(appToken: apptoken, id: bundle, displayName: appName, duration: duration, numberOfPickups: numberOfPickups)
list.append(app)
}
}
}
}
}
return ActivityReport(totalDuration: totalActivityDuration, apps: list)
}
plateform: iPadOS 16.3.1
xcode:15.2
code:
self.queue = Queue()
self.monitor = NWPathMonitor()
self.monitor.pathUpdateHandler = { [weak self] path in

Hello, I have been using the App-prefs:General&path=SOFTWARE_UPDATE_LINK URL in my application to navigate to system settings, and it worked as expected. However, after updating to iOS 18, it no longer works, and I haven't been able to find a replacement.
Is there any alternative solution or a different URL that works?
I also tried prefs:root=General&path=SOFTWARE_UPDATE_LINK, but it didn’t work either.
There are different kinds of screen-sharing applications, all using different APIs.
The API used by AnyDesk, for example, or TeamViewer, which doesn't require light signals.
I wonder if this is more appropriate for a corporate application, i.e. MDM,
A screen-sharing application could be created and validated by Apple to display no light signals, and which could access the user's screen whenever the person wanted to after an initial acceptance?
In other words, the user accepts to share his screen once, but won't be notified to accept the next time.
Or is this impossible on iOS?
I'd be honored to have some answers
In my application, there is a Network Extension with the bundle ID com.xxx.agent.yyy.zzz.ne. There is a user upgraded their system to macOS Sequoia 15.3, they faced an issue where enabling this Network Extension failed. Even after uninstalling the application and the Network Extension, restarting the system, and reinstalling multiple times, the enabling process still failed.
it alert: Failed to enable the Network Extension.
When checking the status via "systemextension list", it always shows "activated waiting for user".
This shows the normal enabling process log:
This shows the log when the enabling fails upon clicking. Strangely enough, there is no activation operation log when it fails. What could be the problem?
I'm using libxpc in a C server and Swift client. I set up a code-signing requirement in the server using xpc_connection_set_peer_code_signing_requirement(). However, when the client doesn't meet the requirement, the server just closes the connection, and I get XPC_ERROR_CONNECTION_INTERRUPTED on the client side instead of XPC_ERROR_PEER_CODE_SIGNING_REQUIREMENT, making debugging harder.
What I want:
To receive XPC_ERROR_PEER_CODE_SIGNING_REQUIREMENT on the client when code-signing fails, for better debugging.
What I’ve tried:
Using xpc_connection_set_peer_code_signing_requirement(), but it causes the connection to be dropped immediately.
Questions:
Why does the server close the connection without sending the expected error?
How can I receive the correct error on the client side?
Are there any other methods for debugging code-signing failures with libxpc?
Thanks for any insights!

We are experiencing an issue where our iOS app’s network extension (acting as a VPN) is being unexpectedly terminated by the operating system. The termination appears identical to a user-initiated stop, as the extension receives the following call: NEProviderStopReasonUserInitiated.
The issue occurs sporadically but can happen 10–20 times per day on devices with less than 10% free storage.
On one affected device, opening the Camera app (or using the camera within another app like WhatsApp) consistently triggers the issue, making it easily reproducible.
Memory consumption does not seem to be the cause—the extension is stopped while using only ~10MB of memory, well below the 50MB limit.
We noticed a pattern related to swap usage:
• On affected devices, the “Swap Used” column shows very low values (a few MB).
• On unaffected devices, swap usage is significantly higher (hundreds of MB).
• This is the only clear difference we’ve observed.
The issue occurs across different device models and iOS versions (18.2.1 and 17.6.1).
It also happens across different app builds (compiled with Xcode 15.x and Xcode 16.x).
We found a similar report on the Apple Developer Forums:
🔗 https://developer.apple.com/forums/thread/108149
Has anyone else encountered this behavior with Network Extensions? Could low swap usage or system resource constraints be a factor? Any suggestions for debugging or potential workarounds would be greatly appreciated.
I've implemented a custom system extension VPN for macOS using Packet Tunnel Provider.
The VPN is configured with on-demand, and a rule to always connect whenever there's traffic:
onDemandRules = [NEOnDemandRuleConnect()]
As for the tunnel's settings (at the Packet Tunnel Provider), I've configured a split tunnel, so some routes are excluded from the tunnel.
Now I have the following scenario:
The VPN is connected
The Mac enters sleep
The sleep() function is called (at my Packet Tunnel Provider)
The Mac briefly awakes to check emails/push notifications/etc. This traffic is excluded from the tunnel.
What is the expected behavior here? Should the wake function be called because of the on-demand rule? Or should the VPN remain asleep because this traffic is excluded from the tunnel?
Hi team,
We were wondering what's the correct way of configuring a test environment with Apple Pay.
Not sure if this is explicitly mentioned in the documentation, but in order to avoid having the same certificates shared between test and production, should we have a different merchant identifier (and pair of certificates) for test purposes only?
The above is the main question. However, two follow up questions:
Do you know if payment processors usually allow the merchant ID to be configured, so that only payments generated with the prod certificates can be accepted?
Is there any risk of someone getting hold of the certificates generated for the test environment (which are usually less safe than production) and using that to process payments in production?

I'm adding my first in-app purchase to an app, and I'm finding the process incredibly frustrating.
Aside from the Apple Developer Documentation not being clear enough, and kind of glossing over the technical steps required (and their sample code being woefully inadequate), App Store Connect and the testing sandbox simply don't work as they say they do.
For example, in my app I've purchased the IAP and now I want to request a refund. I select the purchase, I choose a refund reason, and this page says, "To set up a test for approved refunds, select any refund reason on the refund request sheet, and submit the sheet. The App Store automatically approves the refund request in the testing environment."
Well, when I re-launch the app the purchase is still there. I can't request a refund again because it says this is a duplicate refund request, so it knows that the purchase has had a request, and it's supposed to have automatically refunded it, but it clearly hasn't.
So, I try clearing the purchase history via the Settings app > Developer > Sandbox Apple Account. Same thing. Purchase remains.
Try clearing purchase history in App Store Connect. Same thing.
How on Earth does anyone get an in-app purchase to work when the entire testing environment is so badly executed?
How do I get past this? The IAP is the last part of the app that needs to be implemented, and I've lost a week on this already.
Hello,
I would like to draw your attention to the following imperfection. For validating purchases of my paid application Guru Maps Pro, I use the download id. This is a unique ID that can replace the Transaction ID for paid applications. However, with the release of the new AppTransaction API, this field is no longer present in the data. I tried parsing the receipt, but that field is absent there as well. The only way to obtain the download id is to send the receipt to the deprecated /verifyReceipt endpoint. This deprecated status concerns me, because at some point it might stop working.
Let me explain a little about why I need this. My users have a guru-account, which they can use both in the web version and on Android. When a user purchases the paid version of the application, they can access the paid features on both web and Android. This works great for in-app purchases, where there is a transaction ID, but it may soon stop working for paid applications because there is no way to determine any ID associated with the purchase. Transaction ID or Download ID – I don't mind which.
I have two standalone app written for watchos (standalone). One to authenticate and one for connectivity to real-world devices. The connectivity app uses the authentication app before every action, Im testing this with two xcode projects I have created and tried different things ended up with this error.

Our product is using IOKit framework for monitoring USB device activities. We have used IOKit framework for getting the notification for USB plugin and un-plugins. With the macOS version 15.3 we are started seeing issue with it. When the notification is received during USB plugin/connection, we are unable to get IOUSBDeviceInterface object which will be used for further processing.
Currently we are seeing the below error every time, while trying to create the IO plugin interface using IOCreatePlugInInterfaceForService API:
create plugin Error: (0xe00002be): (iokit/common) resource shortage
Due to this the we are unable to proceed with the flow further and the entire flow is broken.
These logics work fine in macOS version 15.2 and lower versions without any issues.
logic used:
USBDevice::initInterfaceInterfaceByIOService(io_service_t entry)
{
IOCFPlugInInterface** plugInInterface = NULL;
IOUSBInterfaceInterface** interface = NULL;
SInt32 score = 0;
mach_error_code err =
IOCreatePlugInInterfaceForService(entry, kIOUSBInterfaceUserClientTypeID, kIOCFPlugInInterfaceID, &plugInInterface, &score);
if ((err != 0) || (!plugInInterface)) {
os_log_error(OS_LOG_DEFAULT, "Unable to create plugin \n");
return nullptr;
}
auto result = (*plugInInterface)->QueryInterface(plugInInterface, CFUUIDGetUUIDBytes(kIOUSBInterfaceInterfaceID), (LPVOID*)&interface);
(*plugInInterface)->Release(plugInInterface);
if (result || !interface) {
os_log_error(OS_LOG_DEFAULT, "Unable to create interface \n");
return nullptr;
}

Hello,
I am working on an Apple Wallet pass with NFC functionality but have been facing issues with getting it to work. The pass gets added to Wallet, but the NFC feature does not seem to activate.
Could someone provide a detailed, step-by-step process to properly enable NFC in an Apple Wallet pass? Here is what I have done so far:
1. Set up a Pass Type ID and Certificates:
I have registered a Pass Type ID in my Apple Developer account.
I have generated and installed the required certificates (Pass Type ID certificate and WWDR certificate).
2. Adding the NFC Field:
Added the following nfc field to my pass.json file:
{
"formatVersion": 1,
"passTypeIdentifier": "pass.com.example.mypass",
"serialNumber": "123456",
"teamIdentifier": "TEAMID12345",
"webServiceURL": "https://example.com/api/passes",
"authenticationToken": "my_secure_token",
"nfc": {
"message": "Tap to unlock door",
"encryptionPublicKey": "MY_ENCRYPTION_PUBLIC_KEY",
"payload": "encrypted_nfc_payload"
},
"organizationName": "My Company",
"description": "NFC-Enabled Access Pass",
"logoText": "My NFC Pass",
"foregroundColor": "rgb(255, 255, 255)",
"backgroundColor": "rgb(0, 0, 0)",
"barcode": {
"format": "PKBarcodeFormatQR",
"message": "https://example.com",
"messageEncoding": "iso-8859-1"
}
}
3. Tested the Pass:
The pass is added to Wallet, but NFC functionality is not working.
When the nfc field is removed, the pass works fine without NFC.
Questions:
1. Could you provide a comprehensive list of required steps to enable NFC in an Apple Wallet pass, including any specific details on encryption, payload, and public key formatting?
2. Are there any additional configurations or settings that I might be missing?
3. Is there any official documentation or specific tools recommended for testing NFC-enabled passes?
Any guidance or solutions to enable NFC in this pass would be greatly appreciated.
Thank You

Is it possible to track history using the new HistoryDescriptor feature in SwiftData? Or can I only get the current most recent data? Or is it possible to output the changed data itself, along with timestamps?
I am hoping that it is possible to track by a standard feature like NSPersistentHistoryTransaction in CoreData.
Do we still have to use a method in SwiftData that creates more tracking data itself?
I have a simple model
@Model
final class Movie: Identifiable {
#Index\<Movie\>(\[.name\])
var id = UUID()
var name: String
var genre: String?
init(name: String, genre: String?) {
self.name = name
self.genre = genre
}
}
I turned on SQL debugging by including '-com.apple.CoreData.SQLDebug 3' argument on launch.
When I fetch the data using the following code, it selects 3 records initially, but then also selects each record individually even though I am not referencing any other attributes.
var fetchDescriptor = FetchDescriptor\<Movie\>()
fetchDescriptor.propertiesToFetch = \[.id, .name\]
fetchDescriptor.fetchLimit = 3
do {
print("SELECT START")
movies = try modelContext.fetch(fetchDescriptor)
print("SELECT END")
} catch {
print("Failed to load Movie model.")
}
I see it selecting the 3 rows initially, but then it selects each one separately. Why would it do this on the initial fetch? I was hoping to select the data that I want to display and let the system select the entire record only when I access a variable that I did not initially fetch.
CoreData: annotation: fetch using NSSQLiteStatement <0x600002158af0> on entity 'Movie' with sql text 'SELECT 1, t0.Z_PK, t0.ZID, t0.ZNAME FROM ZMOVIE t0 LIMIT 3' returned 3 rows with values: (

)
CoreData: annotation: fetch using NSSQLiteStatement <0x600002154d70> on entity 'Movie' with sql text 'SELECT 0, t0.Z_PK, t0.Z_OPT, t0.ZGENRE, t0.ZID, t0.ZNAME FROM ZMOVIE t0 WHERE t0.Z_PK = ? ' returned 1 rows

)
This all happens between the SELECT START and SELECT END print statements. Why is it fulfilling the faults immediately?

I'm attempting to leverage notifications in an app that is in Swift 6 language mode. I have the following code:
func startLocationUpdates() {
//if self.manager.authorizationStatus == .notDetermined {
// self.manager.requestWhenInUseAuthorization()
//}
self.logger.info("Starting location updates")
Task {
do {
let updates = CLLocationUpdate.liveUpdates()
for try await update in updates {
if !self.updatesStarted { break } // End location updates by breaking out of the loop.
self.lastUpdate = update
if let loc = update.location {
self.lastLocation = loc
self.isStationary = update.stationary
self.count += 1
self.logger.info("Location \(self.count): \(self.lastLocation)")
}
if lastUpdate!.insufficientlyInUse {
let notification = UNNotificationRequest(identifier: "com.example.mynotification", content: notificationContent, trigger: nil)
try await UNUserNotificationCenter.current().add(notification)
}
}
} catch {
self.logger.error("Could not start location updates")
}
return
}
}
As an aside, the above is directly taken from the following sample:
https://developer.apple.com/documentation/CoreLocation/adopting-live-updates-in-core-location.
With Swift 6 language mode enable, this generates a compiler error for the statement:
try await UNUserNotificationCenter.current().add(notification)
Sending main actor-isolated 'notification' to nonisolated instance method 'add' risks causing data races between nonisolated and main actor-isolated uses
How can I fix this?
