I am the Lead iOS Developer for The Incc, an upcoming social networking application. The platform offers subscriptions that grant users access to premium content, primarily digital magazines showcasing diverse cultures, alongside standard social media features and additional unique functionalities.
I am exploring two specific use cases for our subscription model.
Promo Codes with Split Payments:
We plan to collaborate with the our influencers (referred to as Mover Shakers) by providing them with promo codes for users to purchase subscriptions. For such purchases, we aim to implement a revenue split model, allocating 10% to the influencer and the remainder to us after Apple’s fees.
Gifting Subscriptions:
We also wish to enable users to gift subscriptions to others within the app.
I understand that the Apple Subscription Service does not natively support these features.
What other options do we have to achieve this that are also not against the Apple's guidelines.

Hi,
I'm not too good with terminal stuff, but when I looked at activity monitor, my corespotlightd was using too much of my cpu. I decided to look up solutions on google and stumbled upon this: https://forums.developer.apple.com/forums/thread/675482. I tried some of the commands, and I closed the terminal while sudo was still running because I was getting impatient. Somehow, before I even realized it, I was logged out of my Apple ID and my desktop and downloads files were completely gone. For some reason, my applications are still the same, which makes me wonder if some of the files or folders I had before can still be recoverable. I checked time machine, and I wasn't able to recover anything. How cooked am I? I've lost all of my university work and some other pictures and stuff that I thought would never be damaged if I had it locally. Would appreciate any type of help. Thanks.

Hello, dear engineer:
The UWB Accessory used by my APP has inconsistent code callbacks on iOS17 and iOS18.
I have connected multiple UWB Accessory by Accessory Single Configuration Data (UUID: 95e8d9d5-d8ef-4721-9a4e-807375f53328) in the APP.
In iOS17.5.1, the unconnected Accessory calls the func session in the NiSessionDelegate (_ session: NISession, didRemove nearbyObjects: [NINearbyObject], "reason: NINearbyObject RemovalReason)," reason is the timeout.
iOS18.0.1 does not call didRemove and fails to connect automatically after 10 minutes on the disconnected Accessory.
iOS18.2 does not call didRemove. After 10 minutes, when the Accessory is not connected, it automatically connects and starts ranging.
Therefore, I would like to ask what is updated in iOS18 UWB? Is there a document for reference, or can you provide the callback performance of each iOS version for UWB?
The code is as follows:
niConfiguration = try NINearbyAccessoryConfiguration(data: Data(AccessoryUwbConfigData))
uwbSession.run(niConfiguration)

Dear Apple engineers,
Is it possible to make a fileprovider cloud volume mount path independent of the user's home folder in order to have constant path across desktop clients when files are referenced / placed by applications like Adobe Creative Cloud ?
Ideally mount or link the fileprovider cloud volume under /Volumes
Thanks,
I've been working on implementing alternate app icons for my iOS app, and everything works perfectly in debug builds on both the simulator and a physical device. However, when testing on TestFlight, I encounter the following error:
The requested operation couldn’t be completed because the feature is not supported.
Has anyone faced this issue before? Is there a specific TestFlight configuration or setup I might be missing to enable alternate app icon functionality?
Hello, our app gets rejected as it crashes on launch. According to the logs, it happens because the app attempts to access private-sensitive data. We don't collect any of personal data, so it is probably done by Google Firebase embedded in the app (Core, Firestore, Auth). Maybe you have met similar cases and know any of Firebase settings that disable attempts of accessing privacy-sensitive data? We already set FirebaseDataCollectionDefaultEnabled to NO in info.plist, but it still not enough. Maybe error in facebook sdk? Before that it was written that there was an error when starting the ipad air 5

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!
Hi, I am trying to build a command line app that read local mov files and print the text to the terminal. When I open the file with VNImageRequestHandler(url: url), where the url is a hardcode path to my desktop file, the terminal reports CRImage Reader Detector was given zero-dimensioned image (0 x 0). Anyone can help? Thanks!

I have a app with two targets: a main DeviceActivityApp target and a DeviceReport target. In the DeviceReport target, I have a TotalActivityReport struct conforming to DeviceActivityReportScene. Inside its makeConfiguration method, I update a dynamically generated list of AppReport items. The list updates correctly in the DeviceReport target.
// Define which context your scene will represent.
let context: DeviceActivityReport.Context = .totalActivity
// Define the custom configuration and the resulting view for this report.
let content: (MonitorDeviceReport) -> TotalActivityViewFirst
@ObservedObject var activityData:ActivityData
func makeConfiguration(representing data: DeviceActivityResults<DeviceActivityData>) async -> MonitorDeviceReport {
// Reformat the data into a configuration that can be used to create
// the report's view.
var appList:[AppsReport]=[]
let totalActivityDuration = await data.flatMap { $0.activitySegments }.reduce(0, {
$0 + $1.totalActivityDuration
})
for await _data in data{
for await activity in _data.activitySegments{
for await category in activity.categories{
for await app in category.applications{
let name=app.application.localizedDisplayName ?? "No Name"
let bundleId=app.application.bundleIdentifier ?? "nil"
let duration=app.totalActivityDuration
let appIcon=app.application.token
let app=AppsReport(id:bundleId,duration:duration, name:name, icon:appIcon)
appList.append(app)
}
}
}
}
DispatchQueue.main.async {
activityData.list=appList
}
return MonitorDeviceReport(duration:totalActivityDuration, apps:appList)
}
}
public class ActivityData:ObservableObject{
@Published var list:[AppsReport]=[]
public static let shared = ActivityData()
}. // This is in MonitorReport target
However, I need to access this dynamic list in my MyApp target, specifically in ContentView.swift. I tried using an ObservableObject (ActivityData) to share the data between targets, but the list always appears empty in the MyApp target.
Here’s what I’ve tried so far:
Created a shared ActivityData instance using @Published
Passed the ActivityData instance to TotalActivityReport
Used dependency injection and a singleton pattern for ActivityData
Verified that makeConfiguration updates the list correctly in DeviceReport
What could I be missing? How can I correctly share and access this data across targets?
This is Saeid from Drion.ai Ag company in Germany. We are s marketing startup and we are developing a marketing platform we need to give opportunity to our users to sign in using Apple ID.
I have sent all of the company documents, my ID card, and all documents that we have in our company just to activate the AppID login API and it is nothing after more than 2 months. I had a call from Apple support and she told me to send some documents I did it, but nothing yet.
Is this Apple company's suport for developers?!
I recently started saving a file, where I hold some app state, to an AppGroup in order to share it with my widget extension.
Of the some 16k daily active users of my app, 55 are initially unable to read the file (it might not yet be created). And they are unable to write a file to the AppGroup as well. I only know this due to logging the error to Crashlytics.
Error Reading: "The file “BFTPreferences” couldn’t be opened because you don’t have permission to view it.
Error Code:257"
My App sees this error and informs the user to restart their device. I have not been contacted by any of these users for support, so I assume the restart fixes things.
Has anyone seen this before? Is restarting the device the only fix? Am I doing something wrong?
The only solution I can think of currently is to save the file to the app's Documents directory and save a copy to the AppGroup for use in my extensions. At least then the main app won't have an issue and it will just be the widget unable to display data until a restart.
Reading the file:
do {
// archive data
let data = try PropertyListSerialization.data(fromPropertyList: preferences, format: .xml, options: 0)
// write data
do {
if let groupURL = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: appGroupIdentifier) {
let fullPath = groupURL.appendingPathComponent(preferencesFileName)
try data.write(to: fullPath)
}
else {
fatalError("Unable to find app group \(appGroupIdentifier)")
}
}
catch {
logthis("Failed to write dictionary data to disk. \(error.localizedDescription)")
}
}
catch {
logthis("Failed to archive dictionary. \(error.localizedDescription)")
}
Writing the file:
do {
if let groupURL = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: appGroupIdentifier) {
let fullPath = groupURL.appendingPathComponent(preferencesFileName)
let data = try Data(contentsOf: fullPath)
if let dictionary = try PropertyListSerialization.propertyList(from: data, format: nil) as? NSMutableDictionary {
preferences = dictionary
}
}
else {
fatalError("Unable to find app group \(appGroupIdentifier)")
}
} catch {
if (error as NSError).code == NSFileReadNoSuchFileError {
// file doesn't exist so create it
}
else {
logthis("Couldn't read BFTPreferences:\(error.localizedDescription)\nError Code:\((error as NSError).code)") <--error code 257 is caught here
}
}
When I try to load the device activity report, it takes too long to load data. Is this because of development time? Will the problem be solved when the app is live on the App Store?
If it does not depend on the development profile, then please give me a solution for the fast data loading in the device activity report extension.
Thank you
Hi,
I'm working on implementing Apple Pay on the Web.
I noticed, both on my web but also on official Apple Pay on the Web Demo page (https://applepaydemo.apple.com/apple-pay-js-api) when you're sending request for recurring payment, it takes much longer to get response from Apple server (even in onpaymentauthorized method) than when using regular payment.
You can test on the page mentioned above. When you authorise test card with basic payment it's pretty fast, but when you do authorisation with test card for recurring payment (or Deferred or Automatic Reload) "processing payment" is much longer.
Is there a reason why is this and is there a way to speed it up?
Thank you.
Kind regards,
Zoran
I've created a font family, but Font Book refuses to include it in the English language set, despite my best efforts.
The font has every glyph in the OpenType "Std" set, plus several others.
I've checked various boxes for Latin 1 and Macintosh Character Codepages; plus Unicode ranges for Basic Latin, additional Latin, etc, etc.
I've compared it to several other fonts that are in the English set, and I can't see anything that they have that my fonts don't. (In fact, many of them seem to have much less!)
I've created other fonts that are in the English set, but I've no idea what the difference is.
Given that macOS relies on these Language sets, in order to hide the thousands of unnecessary fonts that are permanently installed in the OS, there ought to be some guidance on how to do this.
Since upgrading to iOS18, roomplan crashes have become more frequent

Looking at my CloudKit Telemetry console I noticed a significant increase in 'Other' errors recently. These errors are impacting user experience and I really don't know how to better understand the issues that may be occurring due to the "other" category. If I query the logs for "other" errors, only 2 results show up for the week. There are 2500+ errors in the telemetry graph (see attached).
Is anyone else experiencing this or does anyone have a suggestion on how I can better understand this issue? Thank you!
Hi everyone,
I'm encountering an issue with StoreKit 2 and subscriptions that I hope someone can help clarify.
Here's the scenario:
A user purchases a subscription.
The user cancels the subscription in their Apple ID settings (it remains active until the end of the billing period).
While the subscription is still active, the user reopens the app and tries to repurchase the same subscription.
The problem:
The purchase() method start well a new billing flow, but once confirmed throws a StoreKitError.unknown.
Despite this error, the subscription gets re-enabled and appears active again in the currentEntitlements.
So my question is why the purchase method throw an error and how to deal with this case ?
I precise I'm currently only working in sandbox, maybe the behavior is different in production (but even in that case there is still a bug in Sandbox that should not happen).
Also in that case the Apple Server Notification API send the webhook with type DID_CHANGE_RENEWAL_STATUS (and subtype AUTO_RENEW_ENABLED), which is expected.
Thanks for help,
Gregoire.
