I am developing "local push" VoIP application. I have a question about issues I found while testing this app. After repeating a test for 24 hours in which a incoming call followed by an immediate disconnect 0.1 seconds later, the iPhone of incommig call side encountered a 0xBAADCA11 error, causing iOS to force-close the app. (The incidence is low, occurring three times in 17280 times incoming call(24 hours.)) This problem found on iOS17.6.1 (iPhone11Pro). When the same test was performed on iOS18.2 (iPhoneSE3), the problem did not occur. Did iOS take something measures against the 0xBAADCA11 error between iOS17.6.1 and iOS18.2? If yes, I want to encourage customers to upgrade to the latest iOS version, please tell me about it? ※I have attached an ips files and sysdiagnose file of the 0xBAADCA11 error occurring. (please refer sysdiagnose also if you need.)

I have also tested this on iOS 26 (Beta 9 and above), and the CallKit call blocking functionality is not working. Numbers that should be blocked still ring through. Caller Identification continues to function as expected, but blocking entries (addBlockingEntry) are ignored.

Hi All, I am facing one problem in my app. That is open battery settings from my app. It is working fine in iOS 16.0.0 and it's not working in iOS 18.6.1 is it possible to make it workable in iOS 18.6.1? If so How to do that? Please help me over this to resolve the problem. Thanks, Nguyen Quang Minh

I have been trying to use TipKit popovers in my App. They all behave as expected in the simulator but on a real device I am seeing some strange behaviors. I have a couple of instances of where the tip is displaying an entire sheet instead of just the popover. In another case I cannot dismiss the Tip. Has anyone seen these behaviors and are there known issues/workarounds for this? I am reluctant to use something that works perfectly in the simulator but gives unpredictable results on a device. Not a good user experience in my opinion.

Hi I'm novice developer. I’m currently developing a phone number blocking app using a Call Directory Handler Extension. The blocking feature works perfectly on iOS 18.5, but it doesn’t seem to function properly on iOS 26 beta 4. The extension is invoked, and the numbers are passed correctly, but incoming calls are not being blocked as expected. Is there a known issue with CallKit or Call Directory Extensions on iOS 26 beta 4

Description: I have developed an iOS app that includes a sticker pack feature. However, when adding stickers to iMessage, they are not appearing as expected. Despite following the standard procedures, the stickers are not visible in the iMessage app. The issue persists even after ensuring compatibility with the latest iOS version. Attached is an image that highlights the problem. Any guidance or suggestions to resolve this issue would be greatly appreciated. Thank you!

Prior to 18.x, this has worked for years. However, if a port is included, the behavior in 18.x is to return "///some/path". In all previous versions it correctly returns "/some/path". Is this a bug, or documented change we missed? func relativeURLString(for urlString: String) -> String? { guard var components = URLComponents(string: urlString) else { return nil } components.host = nil components.scheme = nil // WE FOUND IF YOU NIL THE PORT BEFORE HOST AND SCHEME, IT WORKS components.port = nil return components.string }

Hello, My code calls a macOS system library which returns Foundation Date properties. I have a program that will run every night, and output the data via the Swift JSONEncoder and uses DateEncodingStrategy.iso8601. As you likely know, a DST shift happened over the weekend here in the US. In my output, every single Date changed by 1 hour, despite the fact that nothing in the underlying data changed overnight. Here is an example diff in the output. I see the "Z", which I think should not be affected by DST changes. - "dateAdded" : "2003-12-15T17:02:56Z", - "dateModified" : "2007-03-07T04:31:16Z", + "dateAdded" : "2003-12-15T18:02:56Z", + "dateModified" : "2007-03-07T05:31:16Z", Here is a sample of the data: public struct Track: Codable, Hashable { var dateAdded: Date? var dateModified: Date? } And the encoding is here: extension Array where Element == Track { public func jsonData() throws -> Data { let encoder = JSONEncoder() encoder.outputFormatting = [.prettyPrinted, .sortedKeys] encoder.dateEncodingStrategy = .iso8601 return try encoder.encode(self) } } Pretty basic stuff overall. So my questions are: Am I correct in my assumption that .iso8601 is UTC, and that UTC is daylight savings shift agnostic? Is this the right way to ensure the my JSON is encoded in UTC? If the library I am calling is building its Date incorrectly, how may I work around the problem? I'm not reporting the library name right now, in order to ensure that my code is doing the right thing without assumptions. Thanks for any tips!

I'm trying to add Siri support to my app for sending voice messages. I've implemented INSendMessageIntentHandling in my main app target. It looks like it's getting as far as recording the voice message and passing my intent handler an INSendMessageIntent with an audio attachment, but I'm not able to read the attachment file. func handle( intent: INSendMessageIntent, completion: @escaping (INSendMessageIntentResponse) -> Void ) { if let attachment = intent.attachments?.first, let audioFile = attachment.audioMessageFile, let fileURL = audioFile.fileURL { // This branch runs // fileURL is "file:///var/mobile/tmp/SiriMessages/89F738F7-6092-439A-B4FA-2DD9A99F0EED.caf" let result = processMessageAudio(url: fileURL) completion(result) return } // This line isn't reached completion(.init(code: .failure, userActivity: nil)) } private func processMessageAudio(url: URL) -> INSendMessageIntentResponse { var fileRef: ExtAudioFileRef? if url.startAccessingSecurityScopedResource() { logDebug("File access allowed") } else { // This branch runs logDebug("File access not allowed") } defer { url.stopAccessingSecurityScopedResource() } let openStatus = ExtAudioFileOpenURL(url as CFURL, &fileRef) // openStatus is -54 (kAudio_FilePermissionError) return INSendMessageIntentResponse(code: .failure, userActivity: nil) } I'm not sure what I'm missing. It looks like there should be an audio file, and Siri shows a preview of the audio for confirmation.

Hello Folks, I recently came through a new API introduced from iOS 18 onwards isSIMInserted and according to the document it is A Boolean property that indicates whether a SIM is present. I really appreciate Apple for introducing such an useful API but there are few queries on what are the requirements for using this API. Query 1: Do we need any special entitlements for making use of this API. ? If yes then what are those entitlements and are these entitlements available openly or we have to raise special request to apple for such entitlements? Query 2: What are the entries required to be added in info.plist for supporting the isSIMInserted api to work. Query 3: Is isSIMInserted api available for all type of apps because mine is a financial stock related app and i am looking forward to use this API for providing more security to the end user while registering through sms. As per the below link this api is only available for mobile Carrier apps but in official document there is no such mention. https://forums.developer.apple.com/forums/thread/760991 Please kindly help me on these queries ? Regards, Carol

On iOS:When one receives a file of type .pages by email, Mail displays a large Pages icon and tapping on it opens Pages. (A long-press brings up the more complicated Actions screen).When one receives a file of type .vcf by email, Mail displays a large Contacts icon and tapping on it opens Contacts. (A long-press brings up the more complicated Actions screen).I have my own custom file type, .ripf, and I want to have the same behaviour because that is what my users will expect. Accordingly, in my app's Info.plist I have a CFBundleDocumentTypes dictionary providing a one-element LSItemContentTypes array referring to the name 'com.universalis.ripcard', and a UTExportedTypeDeclarations dictionary associating the UTTypeIdentifier 'com.universalis.ripcard' with a public.filename-extension 'ripf' and a public.mime-type 'text/vnd.universalis.ripcard'. All the other entries in those two dictionaries are present and correct as far as I can tell. Both CFBundleDocumentTypes[0].CFBundleTypeIconFiles and UTExportedTypeDeclarations[0].UTTypeIconFiles contain a list of icon files for the file type.(That rather long paragraph is to avoid boring people by including the entire Info.plist!)Some things do work..ripf files received via AirDrop bring up a suitable "Open with..." message which mentions my app, and tapping the message opens the app..ripf files received as an email attachment display as an icon. But it is the app's icon and not the icon of the file type.BUTTapping on a received file's icon does not open the app, but only opens the generic Actions screen, offering Message, Mail, WhatsApp, Notes, and only then (after the user has scrolled sideways) "Copy to..." my app.Now, the whole apparatus of CFBundleDocumentTypes and UTExportedTypeDeclarations is obscure and under-documented, and indeed the main documenation for the latter has a big warning at the top saying that it is obsolete and not being updated. That doesn't matter so much. What I need to know is:(Less important): How do I get the right file icon?(More important): How do I get my app to open when the icon is tapped, as Pages and Contacts do? There must be a way – unless special cases for those two apps are wired into iOS itself.

I'm using Live Activity features in my app, but I want to customize the user experience across different Apple devices. Specifically, I'd like to: Keep Live Activity enabled and functioning on the iPhone Disable or prevent Live Activity from appearing on the connected Apple Watch Is this level of device-specific control possible with Live Activity? If so, what's the best approach to implement this functionality? What I've tried: I've looked through Apple's documentation on Live Activity, but couldn't find specific information about device-level control. I've experimented with ActivityKit, but haven't found a clear way to distinguish between iPhone and Apple Watch when pushing updates.

Hello everyone, I hope you’ll all bear with me as I get up to speed. My background is in Unix, procedural languages, mission critical databases and enterprise applications. I’ve just started heading a team with an iOS app used in healthcare that contains confidential patient information (PHI) that's governed by HIPAA and FDA cybersecurity, etc. It seems there’s some contention in the team over whether the app, SQLite db, and medical images belong in the Documents or an Application Support directory in the Library. From everything I’ve read, it seems that Apple’s intent is Library/Application Support. Two questions: Which is the correct location? And hopefully, a few compelling justifications. On one of our iPads, the app stopped displaying what was two years of data in SQLite. I haven’t yet tested for index corruption, however one of the programmers believes this resulted from an iOS update that needed space and cleared data in the cache (but that makes no sense to myself). Feedback highly appreciated. Many thanks, David Why, because somebody has to

I want to display device activity reports for particular selected apps. for getting a daily basis app uses time. Now, what is happening? there are 10 apps selected from the family activity picker but some apps are displayed in the list. I need all 10 apps or more that I will choose from the family activity picker. The bellow code is used for fetching reports. var body: some View { VStack { DeviceActivityReport(context, filter: filter) } } bellow code is used for the filter @State public var filter = DeviceActivityFilter() init(selectedApps: Set<ApplicationToken>, selectedCategories: Set<ActivityCategoryToken>, selectedWebDomains: Set<WebDomainToken>) { self.selectedApps = selectedApps self.selectedCategories = selectedCategories self.selectedWebDomains = selectedWebDomains self.filter = DeviceActivityFilter( segment: .daily( during: Calendar.current.dateInterval( of: .weekOfYear, for: .now )! ), users: .all, devices: .init([.iPhone]), applications: selectedApps, categories: selectedCategories, webDomains: selectedWebDomains ) } You can see we selected 3 apps from family activity picker but we getting 2 apps from DeviceActivityReport extension following code is for device activity report extension let context: DeviceActivityReport.Context = .totalActivity // Define the custom configuration and the resulting view for this report. let content: (ActivityReport) -> TotalActivityView func makeConfiguration(representing data: DeviceActivityResults<DeviceActivityData>) async -> ActivityReport { // Reformat the data into a configuration that can be used to create // the report's view. var res = "" var list: [AppDeviceActivity] = [] let totalActivityDuration = await data.flatMap { $0.activitySegments }.reduce(0, { $0 + $1.totalActivityDuration }) for await d in data { res += d.user.appleID!.debugDescription res += d.lastUpdatedDate.description for await a in d.activitySegments{ res += a.totalActivityDuration.formatted() for await c in a.categories { for await ap in c.applications { if let apptoken = ap.application.token { let appName = (ap.application.localizedDisplayName ??

I have universal links configured for my iOS app which work as expected when the app is installed. When the app is not installed the universal link will go to the browser as expected. What I want to do is redirect to the app store, allow the user to install the app, then redirect them to the initial universal link. Redirecting them to the app store isn't the hard part I can achieve that from the webpage, however I don't know how to save a reference to that initial link to redirect them once they instal the app. What I want the flow to be for a user who doesn't have the app is: visit a universal link (example.com/UUID) redirect to the app store and install the app open the app and redirect to example.com/UUID I've seen some ways people are doing this with the clipboard but I don't love that solution, I also don't want to use a 3rd party service if I can avoid it - how are the 3rd party services making this happen?

In iOS 18 (beta 1-4) when you set openAppWhenRun = false in your AppIntent of your live activity the perform function never gets called. In iOS 16 and 17 my live activities work. I have downloaded other apps and in their live activities any button tab which doesn´t open the app is also doing nothing in iOS 18. Has anyone got this working? Any comments from an Apple engineer on this?

In my Catalyst app I use func setupMailComposer() { // Check if the device can send email guard MFMailComposeViewController.canSendMail() else { print("Mail services are not available") showMailErrorAlert() return } // Create and configure the mail composer let mailComposeVC = MFMailComposeViewController() mailComposeVC.mailComposeDelegate = self // Set the email details mailComposeVC.setToRecipients(["example@example.com"]) mailComposeVC.setSubject("Subject for your email") mailComposeVC.setMessageBody("This is the body of the email.", isHTML: false) // Attach a file (optional) if let filePath = Bundle.main.path(forResource: "example", ofType: "pdf"), let fileData = try? Data(contentsOf: URL(fileURLWithPath: filePath)) { mailComposeVC.addAttachmentData(fileData, mimeType: "application/pdf", fileName: "example.pdf") } // Present the mail composer self.present(mailComposeVC, animated: true, completion: nil) } Since I have updated to macOS 15.1 the canSendMail() function returns false although I have configured Apple Mail (like before in 15.0 where it worked flawlessly).

I'm trying to display my images in a tableView, I'm using NSFIleManager and NSDirectoryEnumerator to get all files in the current folder: NSString *path = @"/Users/eagle/Documents/avatars"; NSFileManager *fileManager = NSFileManager.defaultManager; NSDirectoryEnumerator *directoryEnum = [fileManager enumeratorAtPath:path]; NSString *file; while (file = [directoryEnum nextObject]) { // ... } the problem is that this line file = [directoryEnum nextObject] always returns nil, what gives? I already made sure that this folder has no subfolders and contains only images, so what's the problem here?

If I run an app with a Message Filter Extension on iOS 18 then it works as expected, however if its installed onto a phone with iOS 17.6.1 then there is the following error: dyld[1042]: Symbol not found: _$sSo40ILMessageFilterCapabilitiesQueryResponseC14IdentityLookupE21promotionalSubActionsSaySo0abI6ActionVGvs Referenced from: &lt;C82A1045-98F4-3751-8080-413FD0B0DEEB&gt; /private/var/containers/Bundle/Application/F295C156-9B20-4927-AEFA-C6983388B193/Myapp.app/PlugIns/MyMessageFilterExtension.appex/CequintTextFilterExtension.debug.dylib Expected in: &lt;29BFFA34-9B52-3D14-A254-A0653545B72E&gt; /System/Library/Frameworks/IdentityLookup.framework/IdentityLookup (App built using XCode 16.2). Here's code causing the issue: import IdentityLookup final class MessageFilterExtension: ILMessageFilterExtension {} extension MessageFilterExtension: ILMessageFilterQueryHandling, ILMessageFilterCapabilitiesQueryHandling { func handle(_ capabilitiesQueryRequest: ILMessageFilterCapabilitiesQueryRequest, context: ILMessageFilterExtensionContext, completion: @escaping (ILMessageFilterCapabilitiesQueryResponse) -&gt; Void) { let response = ILMessageFilterCapabilitiesQueryResponse() response.transactionalSubActions = [.transactionalCarrier, .transactionalHealth, .transactionalPublicServices, .transactionalFinance, .transactionalWeather, .transactionalRewards, .transactionalOrders, .transactionalOthers, .transactionalReminders] response.promotionalSubActions = [.promotionalOffers, .promotionalOthers, .promotionalCoupons] completion(response) } Message filter sub actions were introduced in iOS 16, so why is this error occurring when the code is run on iOS 17, but its fine with iOS 18? This isn't specific to my app, its easily reproducable in two minutes - create an app, add a message filter extension target, change the template code to add a transactional or promotional sub action and then run and it'll occur.

I'm just trying to display an image that is stored in the local filesystem, but the more I dig into this the more confused I get. So previously I used this code (it's simplified): func findImage(name: String) -&gt; UIImage? { do { let url = try FileManager.default.url(for: .applicationSupportDirectory, in: .userDomainMask, appropriateFor: nil, create: false) .appendingPathComponent("MyFolder") .appendingPathComponent("\(name).png") guard let image = UIImage(contentsOfFile: url.path) else { return nil } return image } catch { print(error.localizedDescription) } return nil } Notice I create the URL with just .appendingPathComponent() and turning URL to path via url.path. It works! So what's the question? In Improving performance and stability when accessing the file system I've read that you better use the new appendingPathComponent(_:isDirectory:), that's good, will do. Also url.path is deprecated in iOS18. Should I use url.path(percentEncoded:) instead? What should be the value of percentEncoded when accessing the local filesystem? In this adjacent thread I've read: Don't use UIImage(contentsOfFile:) either, because it's a path-based API. There's no URL-based equivalent, which is an Apple clue that should be doing something else. Is this true? Then how should I store and load my images? Just FYI, I create images like this: private func generateThumbnail(name: String) { guard let drawingWidth = canvasGeo?.size.width, let drawingHeight = canvasGeo?.size.height else { return } let thumbnailRect = CGRect(x: 0, y: 0, width: drawingWidth, height: drawingHeight) Task { UITraitCollection(userInterfaceStyle: .light).performAsCurrent { let image = self.canvasView.drawing.image(from: thumbnailRect, scale: UIScreen.main.scale) guard let data = image.pngData() else { return } // -- HERE do { try FileManager.default.createDirectory(at: try FileManager.default.url(for: .applicationSupportDirectory, in: .userDomainMask, appropriateFor: nil, create: true) .appendingPathComponent("MyFolder"), withIntermediateDirectories: true, attributes: nil) let filename = "\(name).png" let url = try FileManager.default.url(for: .applicationSupportDirectory, in: .userDomainMask, appropriateFor: nil, create: true) .appendingPathComponent("MyFolder") .appendingPathComponent(filename) try data.write(to: url, options: .atomic) // -- and HERE } catch { print(error.localizedDescription) } } } } My usecase — just save the user's PencilKit Canvas as an image and display it back to him on a different View. I'm on SwiftUI and iOS 16+. Would be happy to learn the correct way, thanks!
