In the latest beta of Ventura (and perhaps earlier versions) there is a section of the System Settings > General > Login Items pane called "Allow in Background". It appears that helpers (LaunchAgents/LaunchDaemons) that are installed by apps are listed here. As you can see in the screenshot below, I have 3 such items installed on my test system. The per User LaunchAgent for the Google Updater, the WireShark LaunchDaemon for the ChmodBPF script, and the LaunchDaemon for my userspace CoreAudio Driver (labelled "Metric Halo Distribution, Inc."). The WireShark and Google Updater have nice user identifiable names associated with them, whereas my Launch Daemon only has my company name associated with it. I don't see anything in the plists for Wireshark or GoogleUpdater that seem to specify this user-visible string, nor in the bundles the plists point to. How do I go about annotating my LaunchDaemon plist or the helper tool's plist so that the string in this pane helps the user properly identify what this Background item is for so that they don't accidentally turn it off and disable the driver they need to use our audio hardware? Obviously, we will document this, but just as obviously users don't always read the docs, and it would be better if the user just could make the immediate association that this Background item is needed for our CoreAudio driver.

When you correctly implement EntityPropertyQuery on an AppEntity, Shortcuts will expose a "Find Entity" action that calls into entities(matching:mode:sortedBy:limit:). This is demoed in the "Dive into App Intents" session and works as expected. However, with this action, you can change the "All Entity" input to a list variable which changes the action text from "Find All Entity" to "Filter Entity where" still giving you the same filter, sort and limit options. This appears to work as expected too. But, what's unexpected is that this filter action does not appear to call any method on my AppEntity code. It doesn't call entities(matching:mode:sortedBy:limit:). One would think there would need to be a filter(entities:matching:mode:sortedBy:limit:) to implement this functionality. But Shortcut just seems to do it all on it's own. I'm mostly wondering, how is this even working? Here's some example code: import AppIntents let books = [ BookEntity(id: 0, title: "A Family Affair"), BookEntity(id: 1, title: "Atlas of the Heart"), BookEntity(id: 2, title: "Atomic Habits"), BookEntity(id: 3, title: "Memphis"), BookEntity(id: 4, title: "Run Rose Run"), BookEntity(id: 5, title: "The Maid"), BookEntity(id: 6, title: "The Match"), BookEntity(id: 7, title: "Where the Crawdads Sing"), ] struct BookEntity: AppEntity, Identifiable { static var typeDisplayRepresentation: TypeDisplayRepresentation = "Book" var displayRepresentation: DisplayRepresentation { DisplayRepresentation(title: "\(title)") } static var defaultQuery = BookQuery() var id: Int @Property(title: "Title") var title: String init(id: Int, title: String) { self.id = id self.title = title } } struct BookQuery: EntityQuery { func entities(for identifiers: [Int]) async throws -> [BookEntity] { return identifiers.map { id in books[id] } } } extension BookQuery: EntityPropertyQuery { static var properties = QueryProperties { Property(\BookEntity.$title) { EqualToComparator { str in { book in book.title == str } } ContainsComparator { str in { book in book.title.contains(str) } } } } static var sortingOptions = SortingOptions { SortableBy(\BookEntity.$title) } func entities( matching comparators: [(BookEntity) -> Bool], mode: ComparatorMode, sortedBy: [Sort<BookEntity>], limit: Int? ) async throws -> [BookEntity] { books.filter { book in comparators.allSatisfy { comparator in comparator(book) } } } } The example Shortcut first invokes entities(matching:mode:sortedBy:limit:) with comparators=[], sortedBy=[], limit=nil to fetch all Book entities. Next the filter step correctly applies the title contains filter but never calls entities(matching:mode:sortedBy:limit:) or even the body of the ContainsComparator. But the output is correctly filtered.

Thanks for view post. I found some problem on step review in-app-purchase. All item in app purchase hold on "Developer Action Needed" then I check issue i found it because all item in section App Store Localization rejected.

I'm trying to implement Unwanted SMS and Calls reporting in an app I'm doing in my idle time. If I place a UITextField or UITextView inside a ILClassificationUIExtensionViewController, every time I select on such control the extension crashes without any logs. The closet idea I have on why it crashes it has something to do with iOS requesting the dictation feature. I'm using the latest (beta 8 at the time) iOS 16.0 beta on my iPhone 13 pro. Attaching my code here if you want to try for yourself: github

I've been trying to add a CoreSpotlight indexer to my macOS application. The new template for the indexer uses the new appex CSImportExtension style importer. I've been following this -> https://developer.apple.com/documentation/corespotlight/csimportextension I changed the CSSupportedContentTypes in the Info.plist file to the correct file type uti. I added a dummy value into the attributes (see code below) - just setting contentDescription to 'noodle' (easy to search for) class ImportExtension: CSImportExtension {   override func update(_ attributes: CSSearchableItemAttributeSet, forFileAt: URL) throws {     // Add a dummy value, and see whether spotlight finds it     attributes.contentDescription = "noodle" } } I have a number of files on disk that match the uti (and can be found when I search by the file name) Yet, when I build and run my app, the a spotlight search for 'noodle' finds no results. Can anyone give me any advice? I cannot find any indication that the ImportExtension is called (although when I put a log message at the start of the update() call there's no message in the console which seems to suggest it's not being called). Is there any way of debugging this? Cheers and thanks -- Darren.

While attempting to load a Network extension with OSSystemExtensionRequest I keep getting a "didFailWithError error 1". SIP is disabled. Does anyone know what code 1 is and how to fix it?

Hi, I can't get into "manage" sandbox account. I either get to a screen to put my password in. Here there is no way to click "next" or "login". (I have tried pressing "enter" on my keyboard to no effect). Or I get directly into "Cannot Connect" page. I have tried this two days in a row. I have tried turning it off and on again. I have tried logging out and in. Device: iPhone 13 pro max, iOS: 16.0.3 (also tried the version before this)

Hello, maybe anyone know anything about HCE (Host card emulation) feature on iOS? As far as I read, it's not possible to achieve this functionality on iOS, but maybe there are plans to implement that? Or maybe it's clear that it wont be allowed to be used at all? Thanks:)

My application installs a system extension. When I try to remove the app from the Applications folder (cmd + backspace) I get an error message: "The operation can’t be completed right now because another operation is in progress, such as moving or copying an item or emptying the Bin." According to systemextensionsctl the extension state is "terminating for uninstall but still running". I can see an error in the console logs: kernelmanagerd Failed to terminate dext com.my.driver-dk, error: Kernel request failed: (os/kern) invalid address (1) sysextd a category delegate declined to terminate extension with identifier: com.my.driver-dk sysextd failed to terminate extension with identifier: com.my.driver-dk: Optional(Error Domain=kernelmanagerd.KMError Code=38 "(null)") Issue occurs with macOS 13 - works fine with macOS 12 and macOS 11 What is the problem here? Have there been any changes in macOS in that regard?

Hi, we've observed a weird behavior for a small amount of our user that we keep receiving the same token from APNs despite it's shown as Unregistered. When we try to send push to the token, we got an Unregistered error so we remove that token from our server. However, later we would receive an add token request from the client with the same token we just removed, and when we try to send to the token it returns Unregistered again so we remove the token again. This happened 3 times for a user in an hour. The identifierForVendor remains the same for all the requests. We also owns the client and I've checked client code that it's sending the token it received from didRegisterForRemoteNotificationsWithDeviceToken to the server.

The documentation for CGColorRef (https://developer.apple.com/documentation/coregraphics/cgcolorref?language=objc) clearly shows that it is a struct. However, when I try to store a cell's border color using CGColorRef originalColor = self.bg.layer.borderColor and inspect what happens in the debugger, both that property and its copy have the same address. And later when I try to restore the border color the copy still has the same address but is no longer valid and causes a crash on assignment (originalColor is actually an instance variable...) This is all object behavior, not struct behavior. If CGColorRef really was a struct, the contents would have been copied, the instance variable would have had its own address that would never have changed, and the value would have remained valid indefinitely and let me copy it back without a problem. Why is this documented wrong? Was this a recent change? I actually had this code working at some point, and now it's broken.

I'm trying to handle the serverRecordChanged return code you get in CKError when you have a conflict and your using the savePolicy of ifServerRecordUnchanged. According to the CKError.Code.serverRecordChanged documentation, I should be receiving all three records that I need to do a 3-way merge. The problem is that the ancestorRecord (CKRecordChangedErrorAncestorRecordKey can also be used to look it up in the userInfo) doesn't actually contain a record. It only contains the record metadata. Is there something I need to be doing to get the full ancestorRecord in the CKError? If not is it possible to query iCloud for the ancestorRecord? Given that iCloud has the change history (as I understand it), then it is theoretically possible. I just don't know how to do it if it is possible. Are 3-way merges even possible? The design of the serverRecordChanged looks like that is the intent, but I can't see how to do it with the data that CloudKit is providing.

Hi there! Whenever I try to add a new Offer Code for my app's subscription, I get an unknown error. When I get to the last step of the "Create Offer for Codes" flow, I get an error that error reads "An error has occurred. Try again later." I have been getting this same error for over a week now, so any help figuring out how to add new offer codes would be greatly appreciated!

When I tap on one of the buttons in the ShieldAction extension I want to close the shield and open the parent app instead of the shielded app. Is there any way of doing this using the Screen Time API? class ShieldActionExtension: ShieldActionDelegate {      override func handle(action: ShieldAction, for application: ApplicationToken, completionHandler: @escaping (ShieldActionResponse) -> Void) {     // Handle the action as needed.           let store = ManagedSettingsStore()               switch action {     case .primaryButtonPressed:       //TODO - open parent app       completionHandler(.defer)     case .secondaryButtonPressed:       //remove shield       store.shield.applications?.remove(application)       completionHandler(.defer)         @unknown default:       fatalError()     }   }   }

I am trying on iOS 16.1.1 the Nearby Interaction framework. I am testing it on two iPhones 14 Pro Max. The supportsDirectionMeasurement property returns false (!) and the direction property on the NINearbyObjects is nil. Has someone experienced the same issue?

We are integrating iOS 16 recurring payments in our app, everything works fine but we have a few questions Question 1 let recurringPaymentRequest = PKRecurringPaymentRequest(         paymentDescription: "Pro Membership",         regularBilling: regularBilling,         managementURL: url       ) we assume managementURL is supposed to come in the user's wallet where he/she can tap to change the recurring payment option to our backend, but in the wallet, the transaction appears without this URL and have no indication that it is a recurring payment, Can someone guide what we missed Question 2 For apps that only have apple pay on mobile, managementURL can open the app as a deep link from the Wallet app and the user can update or delete the payment method for the automatic reload payment from the app directly, Question 3 For cancellation, the recurring payment app should have some UI where the user can tap which hit our backend and remove the apple pay merchant token from our system and apply cancellation business logic, no apple API involves in the cancellation of recurring payment

We have implemented Universal Links for iOS. We have deployed the following file as per the documentation: /.well-known/apple-app-site-association Everything works fine until my organization applied domain-level block on traffic out side my country. We need to whitelist Apple servers but we cannot find their IPs or domains used to access this file.

This issue has cropped up many times here on DevForums. Someone recently opened a DTS tech support incident about it, and I used that as an opportunity to post a definitive response here. If you have questions or comments about this, start a new thread and tag it with Network so that I see it. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" iOS Network Signal Strength The iOS SDK has no general-purpose API that returns Wi-Fi or cellular signal strength in real time. Given that this has been the case for more than 10 years, it’s safe to assume that it’s not an accidental omission but a deliberate design choice. For information about the Wi-Fi APIs that are available on iOS, see TN3111 iOS Wi-Fi API overview. Network performance Most folks who ask about this are trying to use the signal strength to estimate network performance. This is a technique that I specifically recommend against. That’s because it produces both false positives and false negatives: The network signal might be weak and yet your app has excellent connectivity. For example, an iOS device on stage at WWDC might have terrible WWAN and Wi-Fi signal but that doesn’t matter because it’s connected to the Ethernet. The network signal might be strong and yet your app has very poor connectivity. For example, if you’re on a train, Wi-Fi signal might be strong in each carriage but the overall connection to the Internet is poor because it’s provided by a single over-stretched WWAN. The only good way to determine whether connectivity is good is to run a network request and see how it performs. If you’re issuing a lot of requests, use the performance of those requests to build a running estimate of how well the network is doing. Indeed, Apple practices what we preach here: This is exactly how HTTP Live Streaming works. Remember that network performance can change from moment to moment. The user’s train might enter or leave a tunnel, the user might step into a lift, and so on. If you build code to estimate the network performance, make sure it reacts to such changes. Keeping all of the above in mind, iOS 26 beta has two new APIs related to this issue: Network framework now offers a linkQuality property. See this post for my take on how to use this effectively. The WirelessInsights framework can notify you of anticipated WWAN condition changes. But what about this code I found on the ’net? Over the years various folks have used various unsupported techniques to get around this limitation. If you find code on the ’net that, say, uses KVC to read undocumented properties, or grovels through system logs, or walks the view hierarchy of the status bar, don’t use it. Such techniques are unsupported and, assuming they haven’t broken yet, are likely to break in the future. But what about Hotspot Helper? Hotspot Helper does have an API to read Wi-Fi signal strength, namely, the signalStrength property. However, this is not a general-purpose API. Like the rest of Hotspot Helper, this is tied to the specific use case for which it was designed. This value only updates in real time for networks that your hotspot helper is managing, as indicated by the isChosenHelper property. But what about MetricKit? MetricKit is so cool. Amongst other things, it supports the MXCellularConditionMetric payload, which holds a summary of the cellular conditions while your app was running. However, this is not a real-time signal strength value. But what if I’m working for a carrier? This post is about APIs in the iOS SDK. If you’re working for a carrier, discuss your requirements with your carrier’s contact at Apple. Revision History 2025-07-02 Updated to cover new features in the iOS 16 beta.
