As a part of the video editing app I’m working on, I want to efficiently copy a folder of resources on the same (local) filesystem. Because iOS is on APFS, cloning (CoW) is an option. I read the documentation for clonefile(2) which states that cloning a folder works but is strongly discouraged. I did a small sample project which demonstrates that using clonefile on a folder works correctly and is 10× faster than using FileManager’s copyItem method. My questions: The main one I’m interested in: Why is using clonefile for a folder strongly discouraged? Is FileManager using cloning behind the scenes? Or more exactly how guaranteed are we it will use it? (I know it does, I tried manually cping the resources and it was thousands of times slower.)

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?

Recently, some feedback has been received. After users upgrade to ipados 17.7.7 and return to the login status and restart the App, it will become invalid. We checked the log and found that the content stored in NSUserdefault would be lost after restarting the App. Has anyone encountered this problem?

Hi All, I am currently working on a Network Extension App for MacOS using 3 types of extensions provided by Apple's Network Extension Framework. Content Filter, App Proxy (Want to get/capture/log all HTTP/HTTPS traffic), DNS Proxy (Want to get/capture/log all DNS records). Later parse into human readable format. Is my selection of network extension types correct for the intended logs I need? I am able to run with one extension: Main App(Xcode Target1) <-> Content Filter Extension. Here there is a singleton class IPCConnection between App(ViewController.swift) which is working fine with NEMachServiceName from Info.plist of ContentFilter Extension(Xcode Target2) However, when I add an App Proxy extension as a new Xcode Target3, I think the App and extension's communication getting messed up and App not getting started/Crashing. Here, In the same Main App, I am adding new separate IPCConnection for this extension. Here is the project organization/folder structure. MyNetworkExtension ├──MyNetworkExtension(Xcode Target1) │ ├── AppDelegate.swift │ ├── Assets.xcassets │ ├── Info.plist │ ├── MyNetworkExtension.entitlement │ | ── Main │ |-----ViewController.swift │ └── Base.lproj │ └── Main.storyboard ├── ContentFilterExtension(Xcode Target2) │ ├── ContentFilterExtension.entitlement │ │ ├── FilterDataProvider.swift │ │ ├── Info.plist │ │ ├── IPCConnection.swift │ │ └── main.swift ├── AppProxyProviderExtension(Xcode Target3) │ ├── AppProxyProviderExtension.entitlement │ │ ├── AppProxyIPCConnection.swift │ │ ├── AppProxyProvider.swift │ │ ├── Info.plist │ │ └── main.swift └── Frameworks ├── libbsm.tbd └── NetworkExtension.framework Is my Approach for creating a single Network Extension App with Multiple extensions correct or is there any better approach of project organization that will make future modifications/working easier and makes the maintenance better? I want to keep the logic for each extension separate while having the same, single Main App that manages everything(installing, activating, managing identifiers, extensions, etc). What's the best approach to establish a Communication from MainApp to each extension separately, without affecting one another? Is it good idea to establish 3 separate IPC Connections(each is a singleton class) for each extension? Are there any suggestions you can provide that relates to my use case of capturing all the network traffic logs(including HTTP/HTTPS, DNS Records, etc), especially on App to Extension Communication, where my app unable to keep multiple IPC Connections and maintain them separately? I've been working on it for a while, and still unable to make the Network Extension App work with multiple extensions(each as a new Xcode target). Main App with single extension is working fine, but if I add new extension, App getting crashed. I suspect it's due to XPC/IPC connection things! I really appreciate any support on this either directly or by any suggestions/resources that will help me get better understand and make some progress. Please reach out if in case any clarifications or specific information that's needed to better understand my questions. Thank you very much

We were facing the same error yesterday and tried many different solutions, but none of them worked. However, today the issue resolved itself and everything is working properly now. The issue we were facing was: #1. not getting any product in didReceive method of storekit. #2. it was working sometimes (i.e. if we try 3 times then 1 time we were getting the product

I have an iOS app where I perform BLE scans using the scanForPeripherals() method in CBCentralManager, which requires the NSBluetoothAlwaysUsageDescription permission. Recently, I added BLE accessory scanning using AccessorySetupKit, which requires the NSAccessorySetupKitSupports permission. This is to support the app on devices running iOS 18 (where AccessorySetupKit is available) as well as on earlier iOS versions (where this framework is not available). However, I am facing an issue where including both permissions in the app causes NSAccessorySetupKitSupports to override the NSBluetoothAlwaysUsageDescription permission. As a result, the scanForPeripherals() method in CBCentralManager no longer works on older versions. Is it possible to use both scanning methods in the same app while ensuring the required permissions coexist? If so, how can this be achieved?

I've been trying to setup a successful migration, but it keeps failing with this error: NSCloudKitMirroringDelegate are not reusable and should have a lifecycle tied to a given instance of NSPersistentStore. I can't find any information about this online. I added breakpoints throughout the code in willMigrate, and it originally failed on this line: try? context.save() I removed that, and it still failed. After I reload the app, it doesn't run the migration again and the app loads successfully. I figured since it crashed, it would keep trying, but I guess not. Here's how my migration is setup. enum MigrationV1ToV2: SchemaMigrationPlan { static var schemas: [any VersionedSchema.Type] { [SchemaV1.self, SchemaV2.self] } static var stages: [MigrationStage] { [stage] } static let stage = MigrationStage.custom( fromVersion: SchemaV1.self, toVersion: SchemaV2.self, willMigrate: { context in // Get cycles let cycles = try? context.fetch(FetchDescriptor<SchemaV1.Cycle>()) if let cycles { for cycle in cycles { // Create new recurring objects based on what's in the cycle for income in cycle.income { let recurring = SchemaV2.Recurring(name: income.name, frequency: income.frequency, kind: .income) recurring.addAmount(.init(date: cycle.startDate, amount: income.amount)) context.insert(recurring) } for expense in cycle.expenses { let recurring = SchemaV2.Recurring(name: expense.name, frequency: expense.frequency, kind: .expense) recurring.addAmount(.init(date: cycle.startDate, amount: expense.amount)) context.insert(recurring) } for savings in cycle.savings { let recurring = SchemaV2.Recurring(name: savings.name, frequency: savings.frequency, kind: .savings) recurring.addAmount(.init(date: cycle.startDate, amount: savings.amount)) context.insert(recurring) } for investment in cycle.investments { let recurring = SchemaV2.Recurring(name: investment.name, frequency: investment.frequency, kind: .investment) recurring.addAmount(.init(date: cycle.startDate, amount: investment.amount)) context.insert(recurring) } } //try? context.save() } else { print("The cycles were not able to be fetched.") } }, didMigrate: { context in // Get new recurring objects let newRecurring = try? context.fetch(FetchDescriptor<SchemaV2.Recurring>()) if let newRecurring { for recurring in newRecurring { // Get all recurring with the same name and kind let sameName = newRecurring.filter({ $0.name == recurring.name && $0.kind == recurring.kind }) // Add amount history to recurring object, and then remove matching for match in sameName { recurring.amountHistory.append(contentsOf: match.amountHistory) context.delete(match) } } //try? context.save() } else { print("The new recurring objects could not be fetched.") } } ) } Here's is my modelContainer in the app file. There is a fatal error occurring here that's crashing the app. var sharedModelContainer: ModelContainer = { let schema = Schema(versionedSchema: SchemaV2.self) let modelConfiguration = ModelConfiguration(schema: schema, isStoredInMemoryOnly: false) do { return try ModelContainer( for: schema, migrationPlan: MigrationV1ToV2.self, configurations: [modelConfiguration] ) } catch { fatalError("Could not create ModelContainer: \(error)") } }() Does anyone have any suggestions for this?

We are currently developing a wallet solution that uses the iOS EEA HCE API. During the development of our solution we have been unable to identify how we can opt out of using the native HCE payment modal screen or biometric authentication UI so that we can customise the experience to align with our overall customer experience. The only available customisation is a label below the title of the screen which does not meet our needs. Please can you advise how we can opt out of using the native HCE payment modal screen. If it is not possible to opt out of using the native HCE payment modal screen, please can you provide the rationale for this given the Digital Marketing Act interoperability guidelines and EU Commitments in case AT.40452.

We have had a small number of users of our mac app complaining that the app suddenly can't detect their subscription or previous purchase history. These users are not new, and have been using the app successfully for some time. In the app we do this using the following (very standard) code at app startup: let result: VerificationResult<AppTransaction> = try await AppTransaction.shared For those users experiencing the failure, the result is coming back as unverified. So far we've been unable to find the cause or a solution, but it seems to have become worse with the release of macOS 15.4. We've tried resetting, rebooting and reinstalling the app. It's worth adding the (probably obvious) that it's impossible to test or fault-find with this, because we can't replicate the issue in a development environment. Any suggestions gratefully received.

We are facing a serious issue affecting the Live Activity of the our app. If the app is built with Xcode 16 (16A242) the Live Activity does not appear on devices running iOS 17. The live activity does appear on devices running iOS 18 RC. If we build the code with Xcode 15, the Live Activity appears on iOS 17 as expected. To investigate this we also prepared a demo bare-bones project to make sure the Live Activity presence is not affected by part of the existing code. Again the issue appears even of the demo app. Is this a known issue with Xcode16/iOS 18?

Hello, I've been experimenting with the new NEURLFilter API and so far the results are kind of strange. SimpleURLFilter sample contains a bloom filter that seems to be built from this dataset in pir-service-example. I was able to run SimpleURLFilter sample and configure it to use PIRService from the example repo. I also observed the requests that iOS has been sending: requesting config and then sending /queries request. What I haven't seen is any .deny verdict for any URL. Even when calling NEURLFilter.verdict(for: url) directly I cannot see a .deny verdict. Is there anything wrong with the sample or is there a known issue with NEURLFilter in the current beta (beta 8) that prevents it from working?

In IOS17 and IOS18, core spotlight can only match app contents by searching for the displayName, but cannot hit the contents by using keywords. Moreover, when matching the app content by searching for the "displayName", it requires inputting four consecutive characters to achieve a match.These issues did not occur in iOS 16. What is the reason for this? Here is my code. func addItemToIndex(_ item: QSpotlightItem) { let attributeSet = CSSearchableItemAttributeSet(contentType: .item) attributeSet.title = item.title attributeSet.displayName = item.title attributeSet.contentDescription = item.contentDescription attributeSet.keywords = item.keywords attributeSet.thumbnailData = item.thumbnailImage attributeSet.contactKeywords = item.keywords attributeSet.supportsNavigation = true let searchableItem = CSSearchableItem(uniqueIdentifier: item.id, domainIdentifier: "xxx", attributeSet: attributeSet) searchableItem.expirationDate = .distantFuture CSSearchableIndex.default().indexSearchableItems([searchableItem]) { error in if let error = error { } else { } } }

Hi all, has anybody found the trick how to get SwiftData working with SpotLight Search? Setting the attribute "spotlight" in the Model definition seems to do nothing at all, as pointed out by Paul Hudson in his new book as well (https://www.hackingwithswift.com/quick-start/swiftdata/how-to-index-swiftdata-objects-in-spotlight) Thanks a lot!

Hi, I'm struggling with SwiftData and the components for migration and could really use some guidance. My specific questions are Is it possible to go from an unversioned schema to a versioned schema? Do all @Model classes need to be converted? Is there one VersionedSchema for the entire app that handles all models or one VersionedSchema per model? What is the relationship, if any, between the models given to ModelContainer in a [Schema] and the models in the VersionedSchema in a [any PersistentModel.Type] I have an app in the AppStore. I use SwiftData and have four @Models defined. I was not aware of VersionedSchema when I started, so they are unversioned. I want to update the model and am trying to convert to a VersionedSchema. I've tried various things and can't even get into the migration plan yet. All posts and tutorials that I've come across only deal with one Model, and create a VersionedSchema for that model. I've tried to switch the one Model I want to update, as well as switching them all. Of course I get different errors depending on what configuration I try. It seems like I should have one VersionedSchema for the app since there is the static var models: [any PersistentModel.Type] property. Yet the tutorials I've seen create a TypeNameSchemaV1 to go with the @Model TypeName. Which is correct? An AppNameSchemaV1 which defines four models, or four TypeNameSchemaV1? Any help will be much appreciated

I am trying to set up a message filter extension that will use shared web credentials for basic auth when calling to its ILMessageFilterExtensionNetworkURL. I have associated domains set up for both "messagefilter:" and "webcredentials:" and the message filter IS correctly calling the ILMessageFilterExtensionNetworkURL with each message - so that part is working. As detailed here, I have set up Shared Web Credentials and my view controller is using SecAddSharedWebCredential() to save the creds to the correct domain. Using Authorization services, the creds are auto-filled into my app's login screen. When I go under Settings > Passwords, I see the creds are saved and they are the correct creds to the corrent website that matches ILMessageFilterExtensionNetworkURL. Regardless of all of this, the deferQueryRequestToNetwork() refuses to use the creds and implement Basic Auth in its URL call. It makes the call to the correct URL, it just won't use the Shared Web Creds for basic auth. Any help would be greatly appreciated.

I am using a URLSessionWebSocketTask. When trying to receive messages while the app is backgrounded, the receive() method fails with an NSError where the domain is NSPOSIXErrorDomain and the code is ECONNABORTED. That behavior is good. However, when this happens, the URLSessionWebSocketTask reports a closeCode of invalid, which is supposed to denote that the connection is still open. However, the connection state property is reporting completed. I feel that the closeCode property should be reporting something like abnormalClosure in this case. Either way, this seems like a bug or the documentation is incorrect.

I'm working on a Network Extension using NEDNSProxyProvider to inspect DNS traffic. However, I've run into a couple of issues: DNS Proxy is not capturing traffic when a public DNS (like 8.8.8.8 or 1.1.1.1) is manually configured in the WiFi settings. It seems like the system bypasses the proxy in this case. Is this expected behavior? Is there a way to force DNS traffic through the proxy even if a public DNS is set? Using DNS Proxy and DNS Settings simultaneously doesn't work. Is there a known limitation or a correct way to combine these?

I was excited to find out about Wi-Fi Aware in i[Pad]OS 26 and was eager to experiment with it. But after wiping and updating two devices (an iPhone 11 Pro and a 2018 11" iPad Pro) to Beta 1 I found out that neither of them support Wi-Fi Aware 🙁. What current and past iPhone and iPad models support Wi-Fi Aware? And is there a new UIRequiredDeviceCapabilities key for it, to indicate that an app requires a Wi-Fi Aware capable device?

Background We sell a suite of iPadOS/macOS apps that share a single auto-renewable subscription using this architecture. Per “Offering a Subscription Across Multiple Apps” we require users to sign in before purchasing so we can propagate the entitlement and avoid duplicate subscriptions across apps. To enforce that sign-in step we plan to turn off Streamlined Purchasing in App Store Connect. Question We also want to distribute subscription offer codes (for promotion, retention, appeasing dissatisfied customers, etc.). After Streamlined Purchasing is turned off, will customers still be able to redeem offer codes outside the app (App Store “Redeem Code” UI or redemption URL)? If outside-app redemption remains possible, it bypasses our sign-in gate and could let the same customer buy the suite twice (once via each app). Is there an approved method to limit offer-code redemption to the in-app flow only, or otherwise prevent such duplicate subscriptions? If no such limitation exists, what best-practice workaround does Apple recommend for multi-app suites that must turn off Streamlined Purchasing yet still wish to use offer codes without duplication risk? Environment StoreKit 2; server-side receipt validation & cross-app entitlement propagation. Apps support the in-app presentCodeRedemptionSheet flow. We expect to use both one-time-use and custom offer codes.
