I want to create a brush similar to a fountain pen, with a three-dimensional feel to the strokes and a distinct tip. Alternatively, is it possible to achieve this by modifying the configuration parameters of a fountain pen brush?

Since iOS 18.3.1, In lower iOS versions it works fine though. QLPreviewController shows a blank white screen instead of showing the document. Additionally, it does not display the 'Done' option at the top-right to close the view. Presenting the QLPreviewController works fine to display the document, but for the second time, it renders the blank white screen as described. While launching QLPreviewControllerView for the first time. I'm receiving the following message in the console and it displays the document. LaunchServices: store (null) or url (null) was nil: Error Domain=NSOSStatusErrorDomain Code=-54 "process may not map database" UserInfo={NSDebugDescription=process may not map database, _LSLine=72, _LSFunction=_LSServer_GetServerStoreForConnectionWithCompletionHandler} Attempt to map database failed: permission was denied. This attempt will not be retried. Closing the QLPreviewController with the help of the 'Done' option from top-right or swipe to close triggers the following message in the console.

Hi all, From what I’ve seen on forums and other sources, it appears that nothing can be done to set the contact poster programmatically. Setting the imageData property affects only the thumbnail image. Does anyone know if this is explicitly documented somewhere? I need this information for a POC document. I watched the iOS 17 keynote (where it was introduced), the Platform State of Union, and other WWDC videos, but I couldn’t find any mention of it. The Contacts framework documentation only explains what can be retrieved from this property and doesn’t mention any way to set the contact poster. If anyone has any information on this, please help! Thanks in advance!

I'm unable to have stickers show in messages even with a new iOS app and a sticker pack extension target. I do see the iMessage App Icon but after tapping it nothing shows and I see a warning: "Error creating the CFMessagePort needed to communicate with PPT" This was tested on simulator and on real device. Xcode 16.1 (16B40) iOS 18.1 & 18.2

Hello! I'm working with universal links in my app and have configured the /.well-known/apple-app-site-association file. Currently, I use the paths array in this file to define URL routing rules. However, I’m struggling to find up-to-date documentation on the pattern syntax supported by the paths field. "paths": [ "/page/*", "NOT /page/*/subpage" ] Could someone clarify: Is the paths array still officially supported, or is it deprecated in favor of the newer components dictionary (as referenced here https://developer.apple.com/documentation/bundleresources/applinks/details-swift.dictionary/components-swift.dictionary)? If paths is still valid, where can I find documentation for its pattern-matching capabilities? I want to ensure my implementation aligns with Apple’s current best practices. Thank you!

I'd like to set the recordingYear in my Spotlight File Importer extension but the property is missing from CSSearchableItemAttributeSet e.g. in the resulting in mdls I'd like to see: kMDItemRecordingYear = 2008; This would allow me to search in Finder by the recording year criteria. There is a recordingDate property and I tried setting it to Date that only has a year but it didn't work. It just resulted in this: kMDItemRecordingDate = "2008-01-01 00:00:00 +0000";

Hello. I'm researching information about Live Caller ID. As I understood Apple using Privacy Pass architecture to retrieve information from the server. I have a question about Privacy Pass Token, where does it stores on device?

Hey everyone, I have an app using the screen time api, I've had quite a few reports from users saying that our monitoring features stop working until they open our app. What happens is that activities and schedules set with the device activity monitor seem to disappear. This is something we check on app re-opens and so we schedule them again and that is why the monitoring starts working again. Of course our current solution is not optimal since our app is mainly passive. Has anyone experienced these kinds of issue ?

Is CallKit still not available in certain countries? like China? If it is, is there a way to get a list of countries?

Hi, We have a need to provide SIM verification. At present, accessing the phone number bound to the device is not programmatically accessible. Would Apple consider exposing this API via a user consent? Otherwise, what is the suggested approach to verify the SIM card is the correct phone number on an iOS device?

Hi There, hopefully someone can help me here, we weren’t aware but our universal links stopped working sometime last year, as they are not used often on the apps, it wasn’t noticed. We checked all the elements and this is the situation: Our apple-app-site-association file is located at https://ourdomain.com.au/.well-known/apple-app-site-association And it is accessible and can be downloaded. We have Associated Domain services enabled for our app Bundle Id: au.com.identifier.app The Entitlements.plist in our app contains the list of associated domains - the second is the full url, the portal won't let me write it as such as it's not the real address. But links for the first two, …ourdomain.com.au domains don’t work Request https://ourdomain.com.au/.well-known/apple-app-site-association downloads the file and returns status code:403 While checking the availability with https://app-site-association.cdn-apple.com/a/v1/ourdomain.com.au we get the error: ourdomain.com.au: Failed to load resource: the server responded with a status of 404 (Not Found) Going directly to the hosted website: https://app-site-association.cdn-apple.com/a/v1/ourdomain-prod-ourdomainwebsite.azurewebsites.net Returns the json: { "activitycontinuation": { "apps": [ "99ABCD88XXX.au.com.identifier.app", "99ABCD88XXX.au.com.identifier.server.adhoc", "99ABCD88XXX.au.com.identifier.server.dev" ] }, "applinks": { "apps": [], "details": [ { "appID": "99ABCD88XXX.au.com.identifier.app", "paths": [ "/m/" ] }, { "appID": "99ABCD88XXX.au.com.identifier.server.adhoc", "paths": [ "/mt/" ] }, { "appID": "99ABCD88XXX.au.com.identifier.server.dev", "paths": [ "/md/*" ] } ] } } It appears to be something in the redirect from the url but debugging shows nothing obvious. Has anyone experienced this before? Thanks

Hi guys, I'm developing a FinderSync Extension that extends Finder contextual menu with a couple of items doing some trivial file operations. I'm using Xcode 16.2 on macOS Sequoia 15.3.2 I could run the containing app in debug, and in System Preferences -> File Providers the flag is enabled for my app finder extension. Anyway, the contextual menu does not show in Finder, probably because the finder extension crashes immediately.

Hey there! I faced issue in iOS 18 and newer when Spotlight search doesn't show my App in results. In older versions it works. Here is my code: func configureUserActivitity(with id: String, keywords: [String]) { let activity = NSUserActivity(activityType: id) activity.contentAttributeSet = self.defaultAttributeSet activity.isEligibleForSearch = true activity.keywords = Set(keywords) activity.becomeCurrent() self.userActivity = activity } I didn't find any reasons why it doesn't work now. Maybe I should report a bug?

Hello, I am unable to figure out how I tell the FamilyActivityPicker whether it should show apps installed on my personal device (to be used with AuthorizationCenter.shared.requestAuthorization(for: .individual)) or apps installed on my child’s device (authenticated their phone via AuthorizationCenter.shared.requestAuthorization(for: .child)). Is there any parameter or SwiftUI modifier I need to apply? Otherwise, how does the user or the app know which token belongs to them and which token belongs to their child’s device? Radar: FB17020977 Thanks a lot for your help!

I have a basic setup following WWDC 2020 on Safari Web Extensions and another one on XPC. The video even mentions that one can use UserDefaults or XPC to communicate with the host app. Here is my setup. macOS 15.2, Xcode 16.2 A macOS app (all targets sandboxed, with an app group) with 3 targets: SwiftUI Hello World web extension XPC Service The web extension itself works and can update UserDefaults, which can then be read by SwiftUI app - everything works by the book. The app can communicate to the XPC service via NSXPCConnection - again, everything works fine. The problem is that the web extension does not communicate with XPC, and this is what I need so that I can avoid using UserDefaults for larger and more complex payloads. Web Ext handler code: class SafariWebExtensionHandler: NSObject, NSExtensionRequestHandling { func beginRequest(with context: NSExtensionContext) { // Unpack the message from Safari Web Extension. let item = context.inputItems[0] as? NSExtensionItem let message = item?.userInfo?[SFExtensionMessageKey] // Update the value in UserDefaults. let defaults = UserDefaults(suiteName: "com.***.AppName.group") let messageDictionary = message as? [String: String] if messageDictionary?["message"] == "Word highlighted" { var currentValue = defaults?.integer(forKey: "WordHighlightedCount") ?? 0 currentValue += 1 defaults?.set(currentValue, forKey: "WordHighlightedCount") } let response = NSExtensionItem() response.userInfo = [ SFExtensionMessageKey: [ "Response to": message ] ] os_log(.default, "setting up XPC connection") let xpcConnection = NSXPCConnection(serviceName: "com.***.AppName.AppName-XPC-Service") xpcConnection.remoteObjectInterface = NSXPCInterface(with: AppName_XPC_ServiceProtocol.self) xpcConnection.resume() let service = xpcConnection.remoteObjectProxyWithErrorHandler { error in os_log(.default, "Received error: %{public}@", error as CVarArg) } as? AppName_XPC_ServiceProtocol service?.performCalculation(firstNumber: 23, secondNumber: 19) { result in NSLog("Result of calculation XPC is: \(result)") os_log(.default, "Result of calculation XPC is: \(result)") context.completeRequest(returningItems: [response], completionHandler: nil) } } } The error I'm getting: Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service named com.***.AppName.AppName-XPC-Service was invalidated: failed at lookup with error 3 - No such process." What am I missing?

We are developing a parental control application in SwiftUI with features like app blocking and screen time management. We are using the Family Control API along with Apple Family Sharing, allowing parents to add multiple children to the family group. We have followed the apple documentation still we are facing following issues: App Blocking Issue: The family picker does not display each child's name separately or their apps individually. Instead, it shows all children's apps together, making it difficult to block apps for a specific child. Screen Time Data Issue: We receive the total screen time usage for all children combined rather than separate screen time data for each child. Syncing Delay: When a new child is added to the Family Sharing group, we are unsure how long it takes for their apps to sync and appear on the parent’s device.

If I run an app with a message filter extension, it's triggered for all the prepaid unknown numbers and its not triggered for all the unknown postpaid numbers. Any idea, how to trigger for postpaid unknown numbers?.

How do I handle force quit in Swift? I received crash reports during a tesflight test. I didn't understand what it was: none of my app's symbols were present, and Xcode didn't want them either... unlike two others who were very specific. By doing a few Google queries, I saw that [UIApplication _terminateWithStatus:] + 136 (UIApplication.m:7578). Accompanied by a SIGSEV... corresponded to a simple thing: it's a crash during a force quit. I tested it with two iPhones, connected to my Mac, and launched the app from Xcode on each of them. I waited a bit, then quit it. It immediately went into the background and waited to launch operations with BackgroundTaskManager. I went to the app carousel and quit it with a swipe of my finger. I immediately see in the log that "sceneDidDisconnect" from SceneDelegate is called... then the immediate crash occurs, with the same elements as those received during the test flight crashlog.crash : SIGSEV and [UIApplication _terminateWithStatus:] and identical elements thereafter. And this applies regardless of what I put in "SceneDidDisconnect," a print, and something to close the BGtasks if they are running (but iOS should normally kill them too, right?) .. 1 or 2 secondes after it crashes. At the moment of the crash, the Xcode cursor is positioned on "class Appdelegate" in AppDelegate. class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate { My question is: how do I handle force quit in Swift? I have another Objective-C application that does the same thing and runs identical operations in the background. If I force quit it, there is no crash.
