I have two standalone app written for watchos (standalone). One to authenticate and one for connectivity to real-world devices. The connectivity app uses the authentication app before every action, Im testing this with two xcode projects I have created and tried different things ended up with this error. authapp://authenticate?callback=linkingapp://callback -[SPApplicationDelegate extensionConnection:openSystemURL:]:2418: URL with scheme "authapp" not supported how to get the url scheme working? Tested this in simulator and real device. info.plist and AppDelegate files are placed in both apps.

Our product is using IOKit framework for monitoring USB device activities. We have used IOKit framework for getting the notification for USB plugin and un-plugins. With the macOS version 15.3 we are started seeing issue with it. When the notification is received during USB plugin/connection, we are unable to get IOUSBDeviceInterface object which will be used for further processing. Currently we are seeing the below error every time, while trying to create the IO plugin interface using IOCreatePlugInInterfaceForService API:
 create plugin Error: (0xe00002be): (iokit/common) resource shortage Due to this the we are unable to proceed with the flow further and the entire flow is broken. These logics work fine in macOS version 15.2 and lower versions without any issues. logic used: USBDevice::initInterfaceInterfaceByIOService(io_service_t entry) { IOCFPlugInInterface** plugInInterface = NULL; IOUSBInterfaceInterface** interface = NULL; SInt32 score = 0; mach_error_code err = IOCreatePlugInInterfaceForService(entry, kIOUSBInterfaceUserClientTypeID, kIOCFPlugInInterfaceID, &plugInInterface, &score); if ((err != 0) || (!plugInInterface)) { os_log_error(OS_LOG_DEFAULT, "Unable to create plugin \n"); return nullptr; } auto result = (*plugInInterface)->QueryInterface(plugInInterface, CFUUIDGetUUIDBytes(kIOUSBInterfaceInterfaceID), (LPVOID*)&interface); (*plugInInterface)->Release(plugInInterface); if (result || !interface) { os_log_error(OS_LOG_DEFAULT, "Unable to create interface \n"); return nullptr; } return interface; }

Hello, I am working on an Apple Wallet pass with NFC functionality but have been facing issues with getting it to work. The pass gets added to Wallet, but the NFC feature does not seem to activate. Could someone provide a detailed, step-by-step process to properly enable NFC in an Apple Wallet pass? Here is what I have done so far: 1. Set up a Pass Type ID and Certificates: I have registered a Pass Type ID in my Apple Developer account. I have generated and installed the required certificates (Pass Type ID certificate and WWDR certificate). 2. Adding the NFC Field: Added the following nfc field to my pass.json file: { "formatVersion": 1, "passTypeIdentifier": "pass.com.example.mypass", "serialNumber": "123456", "teamIdentifier": "TEAMID12345", "webServiceURL": "https://example.com/api/passes", "authenticationToken": "my_secure_token", "nfc": { "message": "Tap to unlock door", "encryptionPublicKey": "MY_ENCRYPTION_PUBLIC_KEY", "payload": "encrypted_nfc_payload" }, "organizationName": "My Company", "description": "NFC-Enabled Access Pass", "logoText": "My NFC Pass", "foregroundColor": "rgb(255, 255, 255)", "backgroundColor": "rgb(0, 0, 0)", "barcode": { "format": "PKBarcodeFormatQR", "message": "https://example.com", "messageEncoding": "iso-8859-1" } } 3. Tested the Pass: The pass is added to Wallet, but NFC functionality is not working. When the nfc field is removed, the pass works fine without NFC. Questions: 1. Could you provide a comprehensive list of required steps to enable NFC in an Apple Wallet pass, including any specific details on encryption, payload, and public key formatting? 2. Are there any additional configurations or settings that I might be missing? 3. Is there any official documentation or specific tools recommended for testing NFC-enabled passes? Any guidance or solutions to enable NFC in this pass would be greatly appreciated. Thank You

Is it possible to track history using the new HistoryDescriptor feature in SwiftData? Or can I only get the current most recent data? Or is it possible to output the changed data itself, along with timestamps? I am hoping that it is possible to track by a standard feature like NSPersistentHistoryTransaction in CoreData. Do we still have to use a method in SwiftData that creates more tracking data itself?

I have a simple model @Model final class Movie: Identifiable { #Index\<Movie\>(\[.name\]) var id = UUID() var name: String var genre: String? init(name: String, genre: String?) { self.name = name self.genre = genre } } I turned on SQL debugging by including '-com.apple.CoreData.SQLDebug 3' argument on launch. When I fetch the data using the following code, it selects 3 records initially, but then also selects each record individually even though I am not referencing any other attributes. var fetchDescriptor = FetchDescriptor\<Movie\>() fetchDescriptor.propertiesToFetch = \[.id, .name\] fetchDescriptor.fetchLimit = 3 do { print("SELECT START") movies = try modelContext.fetch(fetchDescriptor) print("SELECT END") } catch { print("Failed to load Movie model.") } I see it selecting the 3 rows initially, but then it selects each one separately. Why would it do this on the initial fetch? I was hoping to select the data that I want to display and let the system select the entire record only when I access a variable that I did not initially fetch. CoreData: annotation: fetch using NSSQLiteStatement <0x600002158af0> on entity 'Movie' with sql text 'SELECT 1, t0.Z_PK, t0.ZID, t0.ZNAME FROM ZMOVIE t0 LIMIT 3' returned 3 rows with values: ( "<NSManagedObject: 0x600002158d70> (entity: Movie; id: 0xa583c7ed484691c1 <x-coredata://71E60F4C-1A40-4DB7-8CD1-CD76B4C11949/Movie/p1>; data: <fault>)", "<NSManagedObject: 0x600002158d20> (entity: Movie; id: 0xa583c7ed482691c1 <x-coredata://71E60F4C-1A40-4DB7-8CD1-CD76B4C11949/Movie/p2>; data: <fault>)", "<NSManagedObject: 0x600002158f00> (entity: Movie; id: 0xa583c7ed480691c1 <x-coredata://71E60F4C-1A40-4DB7-8CD1-CD76B4C11949/Movie/p3>; data: <fault>)" ) CoreData: annotation: fetch using NSSQLiteStatement <0x600002154d70> on entity 'Movie' with sql text 'SELECT 0, t0.Z_PK, t0.Z_OPT, t0.ZGENRE, t0.ZID, t0.ZNAME FROM ZMOVIE t0 WHERE t0.Z_PK = ?

Why is it fulfilling the faults immediately?

How to create a Notifications Settings button in the Notification Settings similar to Facebook Notification Settings that will lead users to the app's internal settings page?

I'm attempting to leverage notifications in an app that is in Swift 6 language mode. I have the following code: func startLocationUpdates() { //if self.manager.authorizationStatus == .notDetermined { // self.manager.requestWhenInUseAuthorization() //} self.logger.info("Starting location updates") Task { do { let updates = CLLocationUpdate.liveUpdates() for try await update in updates { if !self.updatesStarted { break } // End location updates by breaking out of the loop. self.lastUpdate = update if let loc = update.location { self.lastLocation = loc self.isStationary = update.stationary self.count += 1 self.logger.info("Location \(self.count): \(self.lastLocation)") } if lastUpdate!.insufficientlyInUse { let notification = UNNotificationRequest(identifier: "com.example.mynotification", content: notificationContent, trigger: nil) try await UNUserNotificationCenter.current().add(notification) } } } catch { self.logger.error("Could not start location updates") } return } } As an aside, the above is directly taken from the following sample: https://developer.apple.com/documentation/CoreLocation/adopting-live-updates-in-core-location. With Swift 6 language mode enable, this generates a compiler error for the statement: try await UNUserNotificationCenter.current().add(notification) Sending main actor-isolated 'notification' to nonisolated instance method 'add' risks causing data races between nonisolated and main actor-isolated uses How can I fix this?

I'm working on a game that uses NWBrowser and NWListener to create a connection between an iOS and tvOS app. I've got the initial networking up and running and it works perfectly when running in the simulator(s). However, when I run on-device(s), I've found that browseResultsChangedHandler gets called multiple times for what is ostensibly the same service. My browser handler (which runs on iOS) looks like this: browser.browseResultsChangedHandler = { [weak self] results, changes in if let result = browser.browseResults.first { self?.onPeerConnected?(PeerConnection(endpoint: result.endpoint)) } } The first time it gets called, the interface in the NWBrowser.Result is en0, but the 2nd time it gets called, it is en0 AND awdl0. Because my current handling is so naive, this re-invocation ends up with two connections being made to the remote server (the Apple TV). Now, I know that this handler, by its very name, is designed to be called multiple times as things change, so I'm curious as to what strategies I might employ here. Is there any value in tearing down any previous connections and re-connecting using the latest one? Should I just kill the browser as soon as I handle the first one? Just ignore subsequent ones? I'm sure that, to a degree, the answer is probably "it depends"... but I'm curious to see if there might be at least some high-level strategies like "whatever you do, don't do xxxx" or "most apps do yyyy" :-) Thanks.

MacOS Version: 14.7.2 macOS SDKs: macOS 14.5 -sdk macosx14.5 I am working on a sample program for validation Against: Team Identifier Developer ID I started with validating Team Identifier, but my validation is not working and it is allowing to launch programs which are not matching the team identifier in the signature. Below is my code: func verifyExecutableWithLCR(executablePath: String, arguments: [String]) -&gt; Bool { let task = Process() task.launchPath = executablePath task.arguments = arguments if #available(macOS 14.4, *) { print("launchRequirementData is available on this system.") do { let req = try OnDiskCodeRequirement.allOf { TeamIdentifier("ABCDEFGHI") //SigningIdentifier("com.***.client.***-Client.****") } let encoder = PropertyListEncoder() encoder.outputFormat = .xml let requirementData = try encoder.encode(req) task.launchRequirementData = requirementData print("launchRequirementData is set.") try task.run() print("[SUCCESS] Executable passed the code signature verification.") return true } catch { print("[ERROR] Code signature verification failed: \(error.localizedDescription)") return false } } else { print("[WARNING] launchRequirement is not available on this macOS version.") return false } } Could you please help me in identifying whay am I doing wrong here?

Hi all, I use the FileManager trashIitem function to put a file in the trash. If it is only one file, then the option to put it back is available. If, however, several files are deleted, the option to put it back is only available for the first deleted file. All others cannot be put back. The problem has been known for at least 10 years. See Put back only works for the first file. NSWorkspace recycle has the same problem. It seems to be due to .DS_Store in the trash. The files that are in the trash are stored there. This may also lead you to believe that the trashItem function is working properly because the deleted files are still in the .DS_Store file. If I call trashItem or recycle several times and wait 2 seconds between calls, then the option to put it back is available for all of them. That obviously can't be the solution. Waiting less than 2 seconds only offers to put the first file back. So trashItem and recycle are the same as remove, with the difference that you can look at the files in the trash can again, but not put them back. Are there other ways? The Finder can also delete multiple files and put them all back.

a few times, for reasons unknown to me, asr restore processes broke with error 49244. Basically, the process get interrupted, most cases when is about to finish, with just a laconic message saying "Volume replication failed - error 49244". Where can I get information on this error, what exactly means, what causes it and more important, how to troubleshoot it. Any help will be appreciated, Thanks!!

I am adopting Swift Concurrency in my network extension app to use Swift 6 protections. In the UI app I ended up with most of the app marked as MainActor, so that pieces of my app can keep seamless access to each other and at the same time have thread safe access. When it comes to my network extension, does it make sense to also mark most of the code as MainActor for the purposes of thread safety and seamless access of most classes to each other? I have doubts, because MainActor sounds like it should be a UI think, but network extension has no UI Of course any long or blocking operations would not be MainActor

Is there a way to create a Date constant from year, month and day? The only constructors that show up are .now and those based on some timeInterval. I'm trying to initialize some test data with known dates.

Hello everyone, I’m running an Objective-C–based hybrid (native + web) shopping application and encountering a recurring issue on devices running iOS 18.1.1: When the app launches, it only shows a white screen with the native frame visible—no web content loads. Restarting or reinstalling the app doesn’t help. In one instance, toggling Airplane Mode on and off brought the app back to normal, but this workaround isn’t consistent. There are no crash logs, so we can’t determine if it’s caused by a network error, cache conflict, or an OS-level bug. So far, we have only seen this issue on iOS 18.1.1 devices. Because our app is a shopping platform, this significantly impacts users. Questions: Could this be related to a known bug or limitation in iOS 18.1.1? Are there recommended diagnostic steps or workarounds for a hybrid app that shows a white screen without generating crash logs? Which additional details (e.g., system logs, network traces, device configurations) might help isolate the cause? Any insights or suggestions would be greatly appreciated. Thank you in advance!

On macOS, we have didMountNotification but there doesn't seem to be an equivalent for iOS. Is there a way to be notified when a volume is mounted on iOS? I would like to use it in my iOS app I'm currently porting from macOS, which starts a synchronization from the volume (which has been previously selected in a NSOpenPanel) as soon as it's mounted.

I am developing an app to add Discover cards to Apple Wallet. Unlike Visa, MasterCard, etc., Discover does not have APIs that return activationData, encryptedPassData and ephemeralPublicKey for a given card, so I have created a backend server to handle this. In my server, I am unsure how to generate the ephemeralPublicKey. Do I need to use the merchant certificate? If so, how do I use it to generate the ephemeralPublicKey? I would appreciate it if someone could provide me with a step-by-step guide on how to generate ephemeralPublicKey for provisioning a card.

On macOS, the Finder allows to connect to a server and store the login credentials. When creating a bookmark to a file on a server and resolving it again, the server is mounted automatically (unless I provide the option URL.BookmarkResolutionOptions.withoutMounting). I just tried connecting to my Mac from my iPad via SMB in the Files app and storing a bookmark to a file on the server, but disconnecting the server and trying to resolve the bookmark throws the error (I translated the English text from Italian): Error Domain=NSFileProviderErrorDomain Code=-2001 "No file provider was found with the identifier "com.apple.SMBClientProvider.FileProvider"'" UserInfo={NSLocalizedDescription=No file provider was found with the identifier "com.apple.SMBClientProvider.FileProvider"., NSUnderlyingError=0x302a1a340 {Error Domain=NSFileProviderErrorDomain Code=-2013 "(null) "}} Every time I disconnect and reconnect to the server, selecting the same file returns a different path. The first time I got /private/var/mobile/Library/LiveFiles/com.apple.filesystems.smbclientd/WtFD3Ausername/path/to/file.txt The next time WtFD3A changed to EqHc2g and so on. Is it not possible to automatically mount a server when resolving a bookmark on iOS? The following code allows to reproduce the issue: struct ContentView: View { @State private var isPresentingFilePicker = false @AppStorage("bookmarkData") private var bookmarkData: Data? @State private var url: URL? @State private var stale = false @State private var error: Error? var body: some View { VStack { Button("Open") { isPresentingFilePicker = true } if let url = url { Text(url.path) } else if bookmarkData != nil { Text("couldn't resolve bookmark data") } else { Text("no bookmark data") } if stale { Text("bookmark is stale") } if let error = error { Text("\(error)") .foregroundStyle(.red) } } .padding() .fileImporter(isPresented: $isPresentingFilePicker, allowedContentTypes: [.data]) { result in do { let url = try result.get() if url.startAccessingSecurityScopedResource() { bookmarkData = try url.bookmarkData() } } catch { self.error = error } } .onChange(of: bookmarkData, initial: true) { _, bookmarkData in if let bookmarkData = bookmarkData { do { url = try URL(resolvingBookmarkData: bookmarkData, bookmarkDataIsStale: &amp;stale) } catch { self.error = error } } } } }

We are migrating our iOS app to macOS. On iOS, it works fine. But when I try and run on macOS and connect to the VPN, I am getting an error like failed to fetch /Users/stuart/Library/Developer/Xcode/DerivedData/app-byzvshkqegwzqxgervfswmsughkm/Build/Products/Debug/<app_name>.app/Contents/PlugIns/<network_extension_name>.appex/Contents/_CodeSignature/CodeRequirements-1 error=-10. If I have Settings -> VPN open, it rapidly is connecting and disconnecting. Is there anything I need to do specific to macOS to make this work? Or is this related to a broken code signature? Thanks in advance!

When I click to my Apple Pay button, my function below doesn't trigger the completeMerchantValidation method as expected, but the oncancel method (which logs errorCode "unknown" in Safari developer tools) : const processApplePayment = async () => { if (window.ApplePaySession) { const session = new window.ApplePaySession(6, { countryCode: 'FR', currencyCode: 'EUR', merchantCapabilities: ['supports3DS'], supportedNetworks: ['visa', 'masterCard'], total: { label: `Bon d'achat ${partnerName}`, type: 'final', amount: cartTotalValue.toString() } }); session.onvalidatemerchant = async event => { try { const merchantSession = await validateMerchantSession(event.validationURL); console.log('merchant session : ', merchantSession); if (!merchantSession) { console.error('Invalid Apple Pay merchant session'); } session.completeMerchantValidation(merchantSession); } catch (error) { console.error('merchant validation error : ', error); session.abort(); } }; session.onpaymentauthorized = async event => { console.log('payment authorization event : ', event); try { const link = await authorizePayment( event.payment.token, userInfo, partnerId, order.id ); console.log('payment authorized link : ', link); window.location.href = link; } catch (error) { console.error('Apple Payment authoriation error : ', error); const errorUrl = `${PATH.EBON_ERROR_PATH}-${partnerId}?paiement=error&orderId=${order.id}`; window.location.href = errorUrl; } }; session.oncancel = event => console.log('Apple Pay cancel event : ', event); session.begin(); } }; The validateMerchantSession function successfully returns this payment session from Apple server : { "epochTimestamp":1739279973502, "expiresAt":1739283573502, "merchantSessionIdentifier":"SSH108C7ED6746A48E38EA8D253D33CCAA5_916523AAED1343F5BC5815E12BEE9250AFFDC1A17C46B0DE5A943F0F94927C24", "nonce":"150de193", "merchantIdentifier":"11CA4E31493E748848A91A0DAB1685A8417C41B62B9863EF59A618B91239471A", "domainName":"lesnumeriques-bonsdachat.htmal1.com", "displayName":"Les Numériques", "signature":"308006092a86...779cd643c000000000000", // long string "operationalAnalyticsIdentifier":"Les Numériques:11CA4E31493E748848A91A0DAB1685A8417C41B62B9863EF59A618B91239471A", "retries":0, "pspId":"11CA4E31493E748848A91A0DAB1685A8417C41B62B9863EF59A618B91239471A" } What could I do wrong and how could I fix it please ?

I am working on a duress app and would like to improve location accuracy by encouraging users to enable Wi-Fi. In Apple Maps, I noticed that when Wi-Fi is off, a dialog prompts users to turn on Wi-Fi to enhance location accuracy. I am looking to implement similar functionality in my app. Specifically, I would like to check whether Wi-Fi is enabled on the user's device (even if it is not connected to a network). Despite exploring several methods, I have been unable to determine a reliable way to check the Wi-Fi status. Can you guide me on whether it is possible to access this functionality in iOS, and if so, how I can implement it within my app?
