I have universal links configured for my iOS app which work as expected when the app is installed. When the app is not installed the universal link will go to the browser as expected.
What I want to do is redirect to the app store, allow the user to install the app, then redirect them to the initial universal link. Redirecting them to the app store isn't the hard part I can achieve that from the webpage, however I don't know how to save a reference to that initial link to redirect them once they instal the app.
What I want the flow to be for a user who doesn't have the app is:
visit a universal link (example.com/UUID)
redirect to the app store and install the app
open the app and redirect to example.com/UUID
I've seen some ways people are doing this with the clipboard but I don't love that solution, I also don't want to use a 3rd party service if I can avoid it - how are the 3rd party services making this happen?

When we use AppIntents to configure WidgetKit complications, the description we provide in IntentRecommendation is ignored after applying a .watchface file that includes those intent configurations. In the Watch app, under Complications, the labels shown next to each slot do not match the actual complications on the face—they appear to be the first strings returned by recommendations() rather than the selected intent configuration.
Steps to Reproduce
Create an AppIntent used by a WidgetKit complication (e.g., .accessoryRectangular).
Provide multiple intent recommendations with distinct descriptions:
struct SampleIntent: AppIntent {
static var title: LocalizedStringResource = "Sample"
static var description = IntentDescription("Sample data")
@Parameter(title: "Mode") var mode: String
static func recommendations() -> [IntentRecommendation<Self>] {
[
.init(intent: .init(mode: "A"), description: "Complication A"),
.init(intent: .init(mode: "B"), description: "Complication B"),
.init(intent: .init(mode: "C"), description: "Complication C")
]
}
func perform() async throws -> some IntentResult { .result() }
}
Add two of these complications to a Modular Duo face (or any face that supports multiple slots), each with different intent configurations (e.g., A in one slot, B in another).
Export/share the face to a .watchface file and apply it on another device.
Open the Watch app → the chosen face → Complications.
Expected
Each slot’s label in Complications reflects the specific intent configuration on the face (e.g., “Complication A”, “Complication B”), matching what the complication actually renders.
Actual
The labels under Complications do not match the visible complications. Instead, the strings shown look like the first N items from recommendations(), regardless of which configurations are used in each slot.
Notes
The complications themselves render correctly on-watch; the issue is the names/labels displayed in the Watch app UI after applying a .watchface.

Hello,
I’m working on implementing SB2420 compliance using the Declared Age Range framework.
While referring to the documentation at https://developer.apple.com/documentation/declaredagerange, I couldn’t find details on how the TX region (transaction region or territory) is determined when using Declared Age Range.
Specifically, I’d like to confirm the following points:
How does the system determine the TX region when the user’s declared age range is retrieved?
Is it based on the App Store region, the device locale, or the user’s Apple ID country?
If the app’s backend needs to verify or log the TX region, is there a way to obtain or infer it from the API response or receipt data?
Is there any difference in TX region determination between Sandbox and Production environments?
If anyone has experience implementing Declared Age Range (SB2420) and handling region determination, I’d appreciate your insights or best practices.
Thank you.

When I logged into my cloudkit console to inspect the database for some debugging work I couldn't access the private database. It keeps saying "failed to access iCloud data, please signi n again". No matter how many times I sign in again, whether with password or passwordless key it keeps saying the same thing. It says that message when I click on Public database, and private and shared databases are below it. I only noticed this a couple of days ago. It's done this in the past, but I eventually got back into the database but I don't know what changed to make it work.
On iOS 26 beta 3, after a user purchases an item, initiating a second order for the same product fails to process payment. The system returns the same transaction ID and displays an interface message stating: "You've already purchased this In-App Purchase. It will be restored for free."
I’ve tested this – not only did the legacy StoreKit finishTransaction method fail to work, but StoreKit2 finish method also malfunctioned.
When will Apple fix this issue? If unresolved, it will prevent a large number of users from making purchases normally, leading to disastrous consequences.
Hello!
I make use of the new iOS 15.4 SKAdNetwork.updatePostbackConversionValue feature:
SKAdNetwork.updatePostbackConversionValue(0) { error in
if let error = error {
print(error.localizedDescription)
}
}
I am not sure why, but I always see this error message in the console:
SKAdNetwork: Error while updating conversion value: Error Domain=SKANErrorDomain Code=10 "(null)"
The operation couldn’t be completed. (SKANErrorDomain error 10.)
Any idea what’s going on there? What does Error Code 10 mean? Couldn't find anything in the documentation about that so far.
I have the NSAdvertisingAttributionReportEndpoint key with domain (https://api2.branch.io/v1/skadnetwork/advertiser_app) in my .plist.

Hello! We are in the progress of migrating a large Swift 5.10 legacy code base over to use Swift 6.0 with Strict Concurrency checking.
We have already stumbled across a few weird edge cases where the "guaranteed" @MainActor isolation is violated (such as with @objc #selector methods used with NotificationCenter).
However, we recently found a new scenario where our app crashes accessing main actor isolated state on a background thread, and it was surprising that the compiler couldn't warn us.
Minimal reproducible example:
class ViewController: UIViewController {
var isolatedStateString = "Some main actor isolated state"
override func viewDidLoad() {
exampleMethod()
}
/// Note: A `@MainActor` isolated method in a `@MainActor` isolated class.
func exampleMethod() {
testAsyncMethod() { [weak self] in
// !!! Crash !!!
MainActor.assertIsolated()
// This callback inherits @MainActor from the class definition, but it is called on a background thread.
// It is an error to mutate main actor isolated state off the main thread...
self?.isolatedStateString = "Let me mutate my isolated state"
}
}
func testAsyncMethod(completionHandler: (@escaping () -> Void)) {
let group = DispatchGroup()
let queue = DispatchQueue.global()
// The compiler is totally fine with calling this on a background thread.
group.notify(queue: queue) {
completionHandler()
}
// The below code at least gives us a compiler warning to add `@Sendable` to our closure argument, which is helpful.
// DispatchQueue.global().async {
// completionHandler()
// }
}
}
The problem:
In the above code, the completionHandler implementation inherits main actor isolation from the UIViewController class.
However, when we call exampleMethod(), we crash because the completionHandler is called on a background thread via the DispatchGroup.notify(queue:).
If were to instead use DispatchQueue.global().async (snippet at the bottom of the sample), the compiler helpfully warns us that completionHandler must be Sendable.
Unfortunately, DispatchGroup's notify gives us no such compiler warnings. Thus, we crash at runtime.
So my questions are:
Why can't the compiler warn us about a potential problem with DispatchGroup().notify(queue:) like it can with DispatchQueue.global().async?
How can we address this problem in a holistic way in our app, as it's a very simple mistake to make (with very bad consequences) while we migrate off GCD?
I'm sure the broader answer here is "don't mix GCD and Concurrency", but unfortunately that's a little unavoidable as we migrate our large legacy code base! 🙂
We have an application which is written in Swift, which activates network extension (Transparent Proxy). We want to use MDM deployment for this network system extension.
Our Transparent Proxy module is a system extension, which is exposing an app proxy provider interface (We are using NETransparentProxyProvider class and in extension’s Info.plist we use com.apple.networkextension.app-proxy key.) We don’t have any remote server setup to forward the traffic, instead we open a connection with a certain localhost:port to redirect the traffic which is received in our transparent proxy. We have another module that listens to the particular localhost:port to process the traffic further.
As per https://developer.apple.com/documentation/devicemanagement/vpn/transparentproxy documentation, we noticed that we can use the VPN payload with app-proxy as Provider Type for Transparent Proxy.
We were able to install the profile created via Jamf Pro and also while in stalling our product the Transparent Proxy gets mapped with the one which is installed via profile. However after that the network is broken and hence unable to browse anything. We are suspecting the remote server filed is causing this.
So we tried creating the custom profile without remote server address for VPN payload, but we are unable to install the profile. It throws below error:

Can we create MDM profile for Transparent Proxy without remote server address?
Just wanted to clarify some expected behaviors here. It seems that there are two distinct behaviors for Live Activity flows for freshly installed apps.
When you start a Live Activity for the first time and the user hasn't yet clicked on Allow/Don't Allow in the activity interface, there are two different sequences:
Starting a Live Activity locally
Request a Live Activity locally via Swift
Live Activity starts
.pushTokenUpdates is immediately triggered, even if the Allow/Don't Allow buttons appear under the Activity UI
Starting a Live Activity via push-to-start
Send a push-to-start notification to launch a Live Activity
Live Activity starts
.pushTokenUpdates is not triggered, and .pushToken returns nil.
If a user clicks on Allow in the Activity UI, only then is .pushTokenUpdates triggered.
My app has been in the App Store a few months. In that time I've added a few updates to my SwiftData schema using a MigrationPlan, and things were seemingly going ok. But then I decided to add CloudKit syncing. I needed to modify my models to be compatible. So, I added another migration stage for it, changed the properties as needed (making things optional or adding default values, etc.). In my tests, everything seemed to work smoothly updating from the previous version to the new version with CloudKit. So I released it to my users. But, that's when I started to see the crashes and error reports come in. I think I've narrowed it down to when users update from older versions of the app. I was finally able to reproduce this on my end, and Core Data is throwing an error when loading the ModelContainer saying "CloudKit integration requires that all attributes be optional, or have a default value set." Even though I did this in the latest schema. It’s like it’s trying to load CloudKit before performing the schema migration, and since it can’t, it just fails and won’t load anything. I’m kinda at a loss how to recover from this for these users other than tell them to delete their app and restart, but obviously they’ll lose their data that way. The only other idea I have is to setup some older builds on TestFlight and direct them to update to those first, then update to the newest production version and hope that solves it. Any other ideas? And what can I do to prevent this for future users who maybe reinstall the app from an older version too? There's nothing special about my code for loading the ModelContainer. Just a basic:
let container = try ModelContainer(
for: Foo.self, Bar.self,
migrationPlan: SchemaMigration.self,
configurations: ModelConfiguration(cloudKitDatabase: .automatic)
)
Will UVC native support come for the Iphone as well?
So, using external cameras with the ipad is greatly beneficial, but for the iphone, it can make it a production powerhouse!
So, have there been discussions around bringing UVC support for the Iphone as well? and if so, what were your conclusions?
Hi there 👋🏻
We are facing an issue that started on 24 June 2025 where some users that have an active subscription with an offer are not being able to use/restore their subscription since Transaction.currentEntitlements is empty.
We have tried to call the server with this endpoint https://developer.apple.com/documentation/appstoreserverapi/get-transaction-history and it's returning the correct transactions correctly.
Any idea what is happening?
Hi! I've noticed that the IP_RECVIF socket option, i.e.:
int y = 1;
setsockopt(fd, IPPROTO_IP, IP_RECVIF, &y, sizeof(y));
does not seem to work if the socket is proxied by a NETransparentProxyProvider type network extension: there's no ancillary data in messages received with recvmsg. As soon as I disable the network extension, recvmsg starts returning ancillary data containing the interface name.
This seems to break some applications which rely on IP_RECVIF in the presence of a transparent proxy, making it, in fact, not transparent. One such example is Apple's own libresolv, which relies on IP_RECVIF and breaks if there's no ancillary data in the recvmsg result.
I don't think that this is the intended behaviour, since IPV6_PKTINFO seems to work fine. I've filed a bug report (FB17586550) about this, however, I would greatly appreciate if someone could point me in the direction of a workaround.
We persist ApplicationTokens in a storage container that ShieldConfigurationExtension has access to. In rare, cases all the ApplicationTokens for a user seem to change.
We know this because the Application parameter passed into configuration(shielding application: Application) -> ShieldConfiguration function has a Token that does not match (using == ) any of the ones we are persisting in storage.
Interestingly, the persisted ones still work, so I don't believe storage has gotten corrupted or anything. We can use them to add or remove shields, we can use them to display labels of the apps they represent, etc. But they don’t match what’s passed into the ShieldConfiguration extension. If the user goes into the FamilyPicker at this point and selects an app of a token that we are already persisting, the FamilyPickerSelection will have a token matching the new one that is passed into ShieldConfigurationExtension, not the one we persisted when they last selected that app.
This leads me to believe the tokens are updated/rotated in some cases. When and why does this happen, and how can we handle it gracefully?

WeatherKit Terms of Service accepted in the portal.
Deleted the app, removed any device management profiles, rebooted the phone, clean-built & ran again.
Reproduced the issue in a minimal SwiftUI app that calls: WeatherService.shared.weather(for: CLLocation(latitude: 33.8121, longitude: -117.9190), including: .current) – same Code 2 error.
Request
It looks like the App ID may need a backend entitlement sync. Could someone from the WeatherKit team please check the status for Team 5SZLQLQ9MD, Bundle ID ParkProfessor.ParkProfessorDisneyland and enable WeatherKit token generation?
Thanks!
We have an application, which activates two network extensions (Content Filter, Transparent Proxy) during app launch which is written in Swift.
When we are activating multiple network extensions under the same app bundle, in Ventura and Sonoma, under Privacy and Security it shows "Details" button. On click of it we see below issues:
- It shows the app bundle name instead of respective network extension bundle name.
- On click of OK button, it adds only one extension under "Network -> Filters -> Filters & VPN" and only after machine restart, we can see both the extensions under this screen.
These issues are not seen in Sequoia. In Sequoia, it shows the extension names under the app name. There are separate controls to enable/add each of the extension.
Attached the screenshots of Sonoma and Sequoia for reference
Already submitted the feedback ticket. (FB16331169)
After the macOS Sequoia update, my app seems to have an issue with Bluetooth communication between macOS and iOS that uses CoreBluetooth for Central-Peripheral communication.
Setup:
The iPhone (in my case: iPhone 14 Pro with iOS 18.0 (22A3354)) acts as the Central, and the Mac (in my case: 14" MacBook Pro 2023 with macOS 15.0 (24A335)) as the Peripheral.
I’ve implemented a mechanism where the Central (iPhone) sends a message to the Peripheral (Mac) every 15 seconds to keep the connection alive (Because it needs to wait for notify characteristic updates).
I never noticed this kind of issue before, but with macOS Sequoia I get it permanently.
Issue:
The connection drops unexpectedly after a period of time (sometimes 20 seconds, sometimes a few minutes) with CBErrorDomain - code 6: The connection has timed out unexpectedly.
Sample Code:
Peripheral (Mac):
ContentView (Peripheral).txt
ContentViewModel (Peripheral).txt
Central (iPhone):
ContentView (Central).txt
ContentViewModel (Central).txt
Reproduce:
I attached sample code including the Central-Sample (for iPhone) and Peripheral-Sample (for Mac).
Just run the Peripheral-Sample (after granting Bluetooth permissions).
Then run the Central-Sample and select the Mac device in the list
After selecting it should connect, discover the service & characteristic and should start writing messages to it.
After some time the func centralManager(_ central: CBCentralManager, didDisconnectPeripheral peripheral: CBPeripheral, error: (any Error)?) {should get called with timed out unexpectedly error.
Could anyone please look into this issue and advise on whether there’s a known bug or any workaround? Any guidance would be greatly appreciated, as this impacts the stability of Bluetooth communication between the devices.
Thanks in advance.
Logs:
I also ran the console.app during this issue which got these errors (if this is helpful):
console_logs.txt
I couldn't find any mention in the Wi-Fi Aware documentation https://developer.apple.com/documentation/WiFiAware about the possibilities of the Wi-Fi Aware connection during the app working in the background execution mode (background state).
Does the framework keep the connection alive when the app goes to the background state?
Is there anything similar concept to CoreBluetooth state restoration available in the case of the Wi-Fi Aware framework?

All of my apps stopped working with WeatherKit this morning. They all return an "Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2" error.
I am certain that the WeatherKit capability added (in project) and enabled as a Capability & App Service (on developer portal for the identifier). All other iCloud features of my apps are working as expected. I have also done all the normal troubleshooting using codesign / security cms, etc. to verify entitlements.
I created the following simple project to verify the integration.
import WeatherKit
import CoreLocation
struct ContentView: View {
@State private var temp: Measurement<UnitTemperature>? = nil
var body: some View {
VStack {
if let t = temp {
Text("\(t.value.rounded())°\(t.unit.symbol)")
} else {
Text("Fetching…")
.task {
let service = WeatherService()
do {
let location = CLLocation(latitude: 50.318668, longitude: -114.917710)
let weather = try await service.weather(for: location, including: .current)
temp = weather.temperature
} catch {
print("Error:", error)
}
}
}
}
}
}
Any ideas what may be happening?
