WeatherKit failing on JWT Error
My app AirCompare has been in the app store and successfully using WeatherKit to fetch weather since it became available. Now some (not all) users are encountering the following errors: Failed to generate jwt token for: com.apple.weatherkit.authservice with error: Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)" Encountered an error when fetching weather data subset; location=<+42.40865786,-88.96911526> +/- 0.00m (speed -1.00 mps / course -1.00) @ 6/23/25, 2:56:47 PM Central Daylight Time, error=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors 2 Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)" Others are reporting this same problem here in the forums. We need a solution!

StoreKit 2 failure on tvOS 18.2
Please help! I have a subscription IAP failing on tvOS 18.2 at: func makePurchase(_ product: Product) async throws { let result = try await product.purchase() //ERROR OCCURS HERE (See error message below) ... Xcode Console message: "Could not get confirmation scene ID for [insert my IAP id here]" The IAP subscription was working fine on 18.1 and earlier, and the same IAP and code is also running fine on iOS 18.2. The tvOS error on 18.2 happens both in production and sandbox. Are there any changes to StoreKit 2 which might cause this error?

RCS failing on iOS 18 when VPN active
When a VPN is active, RCS messaging does not work on iOS 18. I work on an iOS VPN app, and we were very appreciative of the excludeCellularServices network flag that was released during the iOS 16 cycle. It's a great solution to ensure the VPN doesn't interfere with cellular network features from the cellular provider. Separately - As a user, I'm excited that iOS 18 includes RCS messaging. Unfortunately, RCS messaging is not working when our VPN is active (when checking on the iOS 18 release candidate). My guess is that RCS is not excluded from the VPN tunnel, even when excludeCellularServices is true. It seems like RCS should be added in this situation, as it is a cell provider service. Can RCS be added as a service that is excluded from the VPN tunnel when excludeCellularServices is true? (I've also sent this via feedback assistant, as 15094270.)

Does "Locked and hidden apps" feature of iOS 18 support deep link?
Our app includes showing external web service with WebView or Safari and returning to the app with custom URL scheme or universal link. When we set "Hide and Require Face ID" feature which was available on iOS 18, neither custom URL scheme nor universal link activated the app. If we only set "Require Face ID", the deep link worked properly. Here is what we've tried: Define custom URL scheme or universal link in the app https://developer.apple.com/documentation/xcode/defining-a-custom-url-scheme-for-your-app https://developer.apple.com/documentation/xcode/supporting-universal-links-in-your-app Implement external web service with one of the following frameworks ASWebAuthenticationSession https://developer.apple.com/documentation/authenticationservices/aswebauthenticationsession/ SFSafariViewController https://developer.apple.com/documentation/safariservices/sfsafariviewcontroller Safari WKWebView https://developer.apple.com/documentation/webkit/wkwebview On iOS 18 device, install the app and set "Hide and Require Face ID" Access external web page and tap the link which activates custom URL scheme or universal link We expected the deep link to work, but the results were: Custom URL scheme &amp;amp; ASWebAuthenticationSession/SFSafariViewController/Safari The system shows "Cannot open the page because the address is invalid" Custom URL scheme &amp;amp; WKWebView Nothing happens when tapping the link Universal link Directed to the server with associated domain file, but the system doesn't call the app which is defined in the associated domain file We tested the feature with the app built with Xcode16 beta 6, and the device with iOS 18 Seed 8(22A5350a). Does hide app feature support custom URL scheme and universal link?

Interactive Widget: unable to reload timeline from AppIntent
My app features two kinds of widgets, let's call them kind A and kind B. I have both A and B widgets on my Home Screen. When I tap the button on widget A (associated with App Intent), I expect widget B to also reload. However, if you call WidgetCenter.shared.reloadAllTimelines() inside the perform() method of the AppIntent, the timeline of widget B does not reload immediately. This issue only occurs on a physical device and is not consistently reproducible. On a simulator, however, widget B reloads as expected. FB13152293

Issue with Property Wrapper Publisher Being Deallocated Prematurely When Not Stored as a Property
Hello everyone, I've built a @CurrentValue property wrapper that mimics the behavior of @Published, allowing a property to publish values on "did set". I've also created my own assign(to:) implementation that works with @CurrentValue properties, allowing values to be assigned from a publisher to a @CurrentValue property. However, I'm running into an issue. When I use this property wrapper with two classes and the source class (providing the publisher) is not stored as a property, the subscription is deallocated, and values are no longer forwarded. Here's the property wrapper code: @propertyWrapper public struct CurrentValue<Value> { /// A publisher for properties marked with the `@CurrentValue` attribute. public struct Publisher: Combine.Publisher { public typealias Output = Value public typealias Failure = Never /// A subscription that forwards the values from the CurrentValueSubject to the downstream subscriber private class CurrentValueSubscription<S>: Subscription where S: Subscriber, S.Input == Output, S.Failure == Failure { private var subscriber: S? private var currentValueSubject: CurrentValueSubject<S.Input, S.Failure>? private var cancellable: AnyCancellable? init(subscriber: S, publisher: CurrentValue<Value>.Publisher) { self.subscriber = subscriber self.currentValueSubject = publisher.subject } func request(_ demand: Subscribers.Demand) { var demand = demand cancellable = currentValueSubject?.sink { [weak self] value in // We'll continue to emit new values as long as there's demand if let subscriber = self?.subscriber, demand > 0 { demand -= 1 demand += subscriber.receive(value) } else { // If we have no demand, we'll cancel our subscription: self?.subscriber?.receive(completion: .finished) self?.cancel() } } } func cancel() { cancellable = nil subscriber = nil currentValueSubject = nil } } /// A subscription store that holds a reference to all the assign subscribers so we can cancel them when self is deallocated fileprivate final class AssignSubscriptionStore { fileprivate var cancellables: Set<AnyCancellable> = [] } fileprivate let subject: CurrentValueSubject<Value, Never> fileprivate let assignSubscriptionStore: AssignSubscriptionStore = .init() fileprivate var value: Value { get { subject.value } nonmutating set { subject.value = newValue } } init(_ initialValue: Output) { self.subject = .init(initialValue) } public func receive<S>(subscriber: S) where S: Subscriber, Failure == S.Failure, Output == S.Input { let subscription = CurrentValueSubscription(subscriber: subscriber, publisher: self) subscriber.receive(subscription: subscription) } } public var wrappedValue: Value { get { publisher.value } nonmutating set { publisher.value = newValue } } public var projectedValue: Publisher { get { publisher } mutating set { publisher = newValue } } private var publisher: Publisher public init(wrappedValue: Value) { publisher = .init(wrappedValue) } } /// A subscriber that receives values from an upstream publisher and assigns them to a downstream CurrentValue property. private final class AssignSubscriber<Input>: Subscriber, Cancellable { typealias Failure = Never private var receivingSubject: CurrentValueSubject<Input, Never>? private weak var assignSubscriberStore: CurrentValue<Input>.Publisher.AssignSubscriptionStore? init(currentValue: CurrentValue<Input>.Publisher) { self.receivingSubject = currentValue.subject self.assignSubscriberStore = currentValue.assignSubscriptionStore } func receive(subscription: Subscription) { // Hold a reference to the subscription in the downstream publisher // so when it deallocates, the susbcription is automatically cancelled assignSubscriberStore?.cancellables.insert(AnyCancellable(subscription)) subscription.request(.unlimited) } func receive(_ input: Input) -> Subscribers.Demand { receivingSubject?.value = input return .none } func receive(completion: Subscribers.Completion<Never>) { // Nothing to do here } public func cancel() { receivingSubject = nil assignSubscriberStore = nil } } public extension Publisher where Self.Failure == Never { /// Assigns the output of the upstream publisher to a downstream CurrentValue property /// - Parameter currentValue: The CurrentValue property to assign the values to func assign(to currentValue: inout CurrentValue<Self.Output>.Publisher) { let subscriber = AssignSubscriber(currentValue: currentValue) self.subscribe(subscriber) } } Here’s an example demonstrating the issue, where two classes are used: Source, which owns the @CurrentValue property, and Forwarder1, which subscribes to updates from Source: final class Source { @CurrentValue public private(set) var value: Int = 1 func update(value: Int) { self.value = value } } final class Forwarder1 { @CurrentValue public private(set) var value: Int init(source: Source) { self.value = source.value source.$value.dropFirst().assign(to: &$value) // The source is not stored as a property, so the subscription deallocates } func update(value: Int) { self.value = value } } With this setup, if source isn’t retained as a property in Forwarder1, the subscription is deallocated prematurely, and value in Forwarder1 stops receiving updates from Source. However, this doesn’t happen with @Published properties in Combine. Even if source isn’t retained, @Published subscriptions seem to stay active, propagating values as expected. My Questions: What does Combine do internally with @Published properties that prevents the subscription from being deallocated prematurely, even if the publisher source isn’t retained as a property? Is there a recommended approach to address this in my custom property wrapper to achieve similar behavior, ensuring the subscription isn’t lost? Any insights into Combine’s internals or suggestions on how to resolve this would be greatly appreciated. Thank you!

Wi-Fi aware in the app's background execution mode
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?

Transaction.currentEntitlements returning empty response
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?

ExtensionKit and iOS 26
It looks like ExtensionKit (and ExtensionFoundation) is fully available on iOS 26 but there is no mention about this in WWDC. From my testing, it seems as of beta 1, ExtensionKit allows the app from one dev team to launch extension provided by another dev team. Before we start building on this, can someone from Apple help confirm this is the intentional behavior and not just beta 1 thing?

Transparent Proxy: Enhancement Requests for setMetadata API
In our setup, our Transparent Proxy (call it TP1) funnels traffic to a helper process running on the same machine (call it Helper), which then actually sends out the traffic to the wider Internet. Now say there's another Transparent Proxy, TP2, on the same machine. Assuming TP1 gets hold of the traffic first, the sequence would look like so: Safari --> TP1 --> Helper --> TP2 We want to make it appear to TP2 that the incoming traffic is from Safari, rather than from the Helper process. We are aware of the Network framework's setMetadata API, but this does not look appropriate for us to use here. The Helper process is pre-existing Golang code, which at best can interface with "pure" (ie BSD) sockets-based C code. In order to use the setMetadata API, looks like we will need to rewrite the entire networking logic to use nw_connection_t (or similar) API, which is too much work, so is infeasible for us to use. Is there a way to make the setMetadata API work at a socket level? e.g., associate the metadata with a socket so that whatever data is sent out on the socket by the Helper will seem to TP2 to be coming from the desired source process. Assuming there isn't such a way, please consider this an Enhancement Request to make it so! Also, this reveals another complication: If and when this Enhancement is implemented, our own TP1 (which interepted the traffic in the first place) would end up thinking that the traffic is from Safari, so ends up re-intercepting it, causing a loop. Safari --> TP1 --> Helper (invokes setMetadata) --> TP1 --> Helper ... Which leads to the next Enhancement Request: Please extend the API to allow setting of the "last-hop" source process in addition to the original source application. If the last-hop source process info is set, our TP1 can query this property, see that it's coming from our own Helper process, and skip interception. In summary, here are the Enhancement Requests: Allow setMetadata API to work at a socket level Allow setting of "last-hop" source process in the metadata, in addition to the original source application More succinctly, please allow setting of metadata to cater to cases where the actual egress happens via a (different) helper process that uses pure C sockets based API. I have also filed this as a Feedback with Apple, at FB16048393.

Shortcuts | Transaction Automation | IOS 18
Hello forum, Hope all is great! I have a shortcut automation which uses the transaction trigger. Since updating to ios 18 the transaction trigger does not work anymore. Whenever a transaction is done, the “Running your automation” notification does not show up and the automation does not work. To share with you the steps I’ve done so far: 1.Remove the automation and do it again 2.Remove the card from apple pay 3. Delete and install again the shortcut app 4. Turned on and off the phone I can confirm the automation works on my other iPhone with the latest version of IOS 17. Would really appreciate if anyone has any insights about that, or if this happened to you as well. Cheers! Dorin

Does Firebase Push Notification Service Need New Certificates Due to APNs Update
Hi, With the upcoming changes to the Apple Push Notification service (APNs) server certificates — including the SHA-2 Root: USERTrust RSA Certification Authority certificate update — I wanted to clarify if we need to take any action with Firebase Cloud Messaging (FCM). Since we’re using FCM to send push notifications to iOS devices, does Firebase also need to update its server certificates in response to these changes, or will Firebase handle the updates automatically? We understand that Apple recommends updating our Trust Store to include the new certificates for APNs, but we’re unsure if any action is needed on our end for FCM specifically. Thanks in advance for the clarification!

Push Notification Certificate Updates
Hello, I received this message below. I reached out to support but they said they can not help with something this specific. Any organization in the same boat? Which of the certificates in the provided link should I use? Hello, We’re reaching out with a final reminder that the Certification Authority (CA) for Apple Push Notification service (APNs) is changing. APNs updated the server certificates in sandbox on January 21, 2025. APNs production server certificates will be updated on February 24, 2025. To continue using APNs without interruption, you’ll need to update your application’s Trust Store to include the new server certificate: SHA-2 Root: USERTrust RSA Certification Authority certificate. To ensure a smooth transition and avoid push notification delivery failures, please make sure that both old and new server certificates are included in the Trust Store before the cut-off date for each of your application servers that connect to sandbox and production. At this time, you don’t need to update the APNs SSL provider certificates issued to you by Apple.

Dynamic Options for Configurable Widgets
Hello, I'm trying to create a widget using the WidgetKit framework. In this part, I'm using Intents along with a DynamicOptionsProvider. As shown in the Medium article below, I want to present multiple options when "Edit Widget" is tapped: https://levelup.gitconnected.com/swiftui-configurable-widget-to-let-our-user-choose-4a54e398f42f However, in this example, the options are provided statically. What I want to achieve is to display a list of devices based on the selected HomeId after the user selects a Home. I’ve set up the interface accordingly, but when I select a Home, the device list does not update. How can I make this work? The two options should be dependent on each other.

PDFKit PDFPage.characterBounds(at:) returns incorrect coordinates iOS 18 beta 4
PDFKit PDFPage.characterBounds(at: Int) is returning incorrect coordinates with iOS 18 beta 4 and later / Xcode 16 beta 4. It worked fine in iOS 17 and earlier (after showing the same issue during the early iOS 17 beta cycle) It breaks critical functionality that my app relies on. I have filed feedback (FB14843671). So far no changes in the latest betas. iOS release date is approaching fast! Anybody having the same issue? Any workaround available?

Issues with Family Control API: App Blocking & Screen Time for Multiple Children
We are developing a parental control application in SwiftUI with features like app blocking and screen time management. We are using the Family Control API along with Apple Family Sharing, allowing parents to add multiple children to the family group. We have followed the apple documentation still we are facing following issues: App Blocking Issue: The family picker does not display each child's name separately or their apps individually. Instead, it shows all children's apps together, making it difficult to block apps for a specific child. Screen Time Data Issue: We receive the total screen time usage for all children combined rather than separate screen time data for each child. Syncing Delay: When a new child is added to the Family Sharing group, we are unsure how long it takes for their apps to sync and appear on the parent’s device.
