Hi there, I'm adding a new widget using the new WidgetConfigurationIntent which takes a number of parameters, including one which conforms to AppEntity. It is defined as an optional. When the user is configuring the widget, after one of the suggested entities is chosen, there is no way to return to a state where this value is nil. Is this possible? I'd like the user to be able to select "None" for this parameter. For now, I'm using a bool to determine whether the AppEntity parameter is used. Thanks!

I am creating a barcode reader using the AVfoundation framework for iOS and IPadOS. The read result goes into payloadstringvalue, but I want to check the control characters contained in the symbol, so I am using the raw data of the description, which is a property of NSObjectProtocol inherited by VNBarcodeObservation. However, I noticed that if the length set in the raw data exceeds 26, some of the raw data in the description is omitted. So my question is, is it possible to set it so that all the raw data in the description is written out without omitting any raw data? If so, could you please tell me how to set this up? Also, if you know of any other way to extract the raw barcode data, I would appreciate it if you could let me know. Thank you.

We are currently experiencing a very interesting issue when accessing the location in the background with CLLocationManager. The user has given our app the "whenInUse" permission for locations and in most cases the app provides location updates even when it's in the background. However, when we started to use other navigation apps in the foreground we saw that the func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) method was called with (kCLErrorDomain error 1.). The user hasn't changed the location permission and we saw that locations were delivered once the user opened the app again. I don't see anything in the documentation explaining this issue, but I chatted with other developers that confirm that specific behavior. Am I missing something here?

I try to call Get Transaction Info from App Store Server API, and the transactionId is for a Non-consumable type product, but it is odd that there are so many different transactionId and they have a same originalTransactionId { "bundleId": "${bundleId}", "environment": "Production", "inAppOwnershipType": "PURCHASED", "originalPurchaseDate": 1691220528000, "originalTransactionId": "${originalTransactionId}", "productId": "${productId}", "purchaseDate": 1691220528000, "quantity": 1, "signedDate": 1692590989925, "storefront": "USA", "storefrontId": "143441", "transactionId": "${originalTransactionId}", "transactionReason": "PURCHASE", "type": "Non-Consumable" } the defination of Non-Consumable is can only purchase once for same apple account. But why there would have originalTransactionId?

Hi there! Sorry in advance, this is going to be a long post of Apple developer pains which I want to share with you, and, hopefully, find the answer and help Apple become better. I'm at the very beginning of my new and exciting personal project which (I hope) may one day feed me and be my daily source of inspiration. I'm not a newbie in Apple development nor am I a senior-level developer — just a fellow developa'. Here's the problem I bring to you — why Apple promotes Unified Logging System and recommends using it as the primary way to implement logging in 3rd-party apps? No doubt, OSLog is a great, secure, efficient, and centralized way to gather diagnostics information, and I, starting my new project, am itching to choose exactly this 1st-party logging infrastructure. This decision in theory has a number of benefits: I don't have to depend on 3rd-party logging frameworks which may eventually be discontinued; I have extensive documentation, great WWDC sessions explaining how to use the framework, and stackoverflow answers from the whole Apple dev community in case I experience any troubles; I have this cool Console.app and upcoming Xcode 15 tools with great visualization and filtering of my logs; It's quite a robust and stable infrastructure which I may restfully rely on. But... the thing is there's this big elephant in the room — this API is non-customizable, inconvenient, and hard to use in terms of the app architecture. I can't write my own protocol wrapper around it to abstract my domain logic from implementation details or just simplify the usage at the call site. I can't configure my own format for log messages (this is debatable, since Console.app doesn't provide "naked strings" as Xcode 14 and earlier, but still). And what's most important — I can't conveniently retrieve the logs! I can't implement the functionality where my user just taps the button, and the logs are sent on the background queue to my support email (eskimo's answer). They would have to go through this monstrous procedure of holding volume buttons on the iPhone, connecting their device to the Mac, gathering sysdiagnose, entering some weird Terminal commands (jeez, these nerdy developers...), etc. If it ever succeeds, of course, and something doesn't go wrong, leaving my user angry and dissatisfied with my app. Regarding the protocol wrapper, I can't do something like this: protocol Logging { var logger: Logger { get } func info(_ message: OSLogMessage) } extension Logging { var logger: Logger { return Logger( subsystem: "com.my.bundle.id", category: String(describing: Self.self) ) } func info(_ message: OSLogMessage) { logger.info(message) } } class MyClass: Logging { func someImportantMethod() { // ... self.info("Some useful debug info: \(someVar, privacy: .public)") } } I've been investigating this topic for 2 days, and it's the farthest I want to go in beating my head over how to do two simple things: How to isolate logging framework implementation decision from my main code and write convenience wrappers? How to easily transfer the log files from the user to the developer? And I'm not the only one struggling. Here's just one example among hundreds of other questions that are being asked on dev forums: https://www.hackingwithswift.com/forums/ios/unified-logging-system-retrieve-logs-on-device/838. I've read almost all Apple docs which describe the modern Unified Logging System, I've read through eskimo's thread on Apple Developer Forum about the API, but I still haven't found the answer. Maybe, I've misperceived this framework and it's not the tool I'm searching for? Maybe, it focuses on different aspects of logging, e.g. signposting, rather than logging the current state of the app? What am I missing?

Hello Everyone, I'm trying to add badges to files in my File Provider Extension for macOS. I'm not trying to create my own Item decorations here, but use the default Icons provided by apple (such as com.apple.icon-decoration.badge.heart , com.apple.icon-decoration.badge.pinned). I've gone through the Sample code provided by Apple for Fruit Basket. I've tried to replicate the same thing in my Extension as well but It seems I'm unable to display Icons. I'm not even getting any Error when the Icons are not being displayed, So I've been stuck for a month on this. These are the Things that I've done below: Folder Structure : FileExplorer |- FileProviderApp | |- UI.swift | |- ContentView.swift |- Extension |- extension.swift |- item.swift |- enumerator.swift |- info.plist According to the instructions given in the Documentation for Decorations here : https://developer.apple.com/documentation/fileprovider/nsfileprovideritemdecorating. The implementation was done as follows: content inside info.plist of the File provider Extension <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>NSExtension</key> <dict> <key>NSExtensionFileProviderSupportsEnumeration</key> <true/> <key>NSExtensionPointIdentifier</key> <string>com.apple.fileprovider-nonui</string> <key>NSExtensionPrincipalClass</key> <string>$(PRODUCT_MODULE_NAME).FileProviderExtension</string> <key>NSFileProviderDecorations</key> <array> <dict> <key>BadgeImageType</key> <string>com.apple.icon-decoration.badge.heart</string> <key>Category</key> <string>Badge</string> <key>Identifier</key> <string>$(PRODUCT_BUNDLE_IDENTIFIER).heart</string> <key>Label</key> <string>Heart Item</string> </dict> </array> </dict> </dict> </plist> In my extension's NSFileProviderItem I've also Implemented the protocol NSFileProviderItemDecorating. and the decoration's method as static let decorationPrefix = Bundle.main.bundleIdentifier! static let heartDecoration = NSFileProviderItemDecorationIdentifier(rawValue: "\(decorationPrefix).heart") var decorations: [NSFileProviderItemDecorationIdentifier]? { var decos = [NSFileProviderItemDecorationIdentifier]() decos.append(Item.heartDecoration) return decos } I was expecting to see badges on the File items in Finder, but i got nothing. When I modified the FruitBasket Project to do the same i was able to see badges, but not when I try to implement it in my Extension. Was I missing a step or is the issue something else ?

My app features two kinds of widgets, let's call them kind A and kind B. I have both A and B widgets on my Home Screen. When I tap the button on widget A (associated with App Intent), I expect widget B to also reload. However, if you call WidgetCenter.shared.reloadAllTimelines() inside the perform() method of the AppIntent, the timeline of widget B does not reload immediately. This issue only occurs on a physical device and is not consistently reproducible. On a simulator, however, widget B reloads as expected. FB13152293

This is a regression since iOS 13. Is there no-one at Apple interested in fixing this? FB9856371

I am developing a FileProvider extension which will be launched for one or more domains. In the case where I have two domains, say with displayNames "Foo" and "Bar", the finder will then show "MyExtension - Foo" and "MyExtension - Bar" respectively after registering them with addDomain. However, if I only have a single domain, let's say "Foo" – then I just see "MyExtension" rather than "MyExtension - Foo". Now ideally I'd like to be able to control the entire name, but barring that at least be able to show the displayName even with a single domain. How can I achieve that?

I created a Notification Service Extension to display profile images in place for the app image (i.e. iMessage). I send a remote push notification via Firebase Functions, and in the payload, the relevant profile image url string. The profile image url string in the payload is successfully delivered as it appears in my console log and AppDelegate didReceiveRemoteNotification function. My problem is the profile image does not replace the default app icon image in the remote push notification. Below is my configuration. Any guidance would be appreciated!

Hi there, This is my first time posting here. I'm working on small projects on Swift and SwiftUI now and then. I'm currently trying to develop an application that gets some bus arrival data using API and displaying them with live activities. The thing is that I'm not quite sure how frequently updates work yet. Still trying to figure out if I can update the live activity everytime the data coming right from the API changes or use push notification updates each minute passing by, but that is another thread that I'm going to focus with more details. Everytime i'm trying to deploy my app on my iphone or a simulator this error keeps popping up and I can't figure out why. Any ideas? Let me know if you need any snippet of my code.

Will UVC native support come for the Iphone as well? So, using external cameras with the ipad is greatly beneficial, but for the iphone, it can make it a production powerhouse! So, have there been discussions around bringing UVC support for the Iphone as well? and if so, what were your conclusions?

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!

Hello everyone, I have been working on a macOS app that utilizes push notifications for the past year. Up until recently, everything was functioning correctly. However, now I'm experiencing issues where push notifications are either not being delivered at all or are experiencing significant delays, sometimes up to 10 minutes. Setting the priority header to 10 hasn't made any difference. I am currently using development push notifications, but the issue persists when switching to the production environment. I'm curious if anyone else has encountered similar problems. When checking the push console, it frequently reports that the device is offline, even though it's actually online ("discarded as device was offline"). Occasionally, notifications are delivered promptly, but this is becoming increasingly infrequent. This issue has been consistently reported by our testers, particularly after they updated to macOS Sonoma. Any insights or assistance you can provide would be greatly appreciated.

Hello, I'm currently experiencing an issue with the DeviceActivityMonitor extension in my code, specifically with the eventDidReachThreshold callback. I'm hoping to get some insights into why this problem occurs and how to resolve it. Problem: Issue 1: The eventDidReachThreshold callback is not triggering as expected. It appears that the callback is not being invoked when the threshold is reached. Issue 2: After a few seconds, the eventDidReachThreshold callback starts to trigger multiple times. This unexpected behavior is causing problems in my code, as it results in incorrect actions being taken. iOS version: iOS16.7.2 and iOS17.1 Xcode version: 15.0.1 Swift version: 5.9 Here is my code to start the monitoring: func startMonitoring() { var startTime : DateComponents = DateComponents(hour: 0, minute: 0) let endTime : DateComponents = DateComponents(hour: 23, minute: 59) /// Creates the schedule for the activity, specifying the start and end times, and setting it to repeat. let schedule = DeviceActivitySchedule(intervalStart: startTime, intervalEnd: endTime, repeats: true, warningTime: nil) /// Defines the event that should trigger the encouragement. let event = DeviceActivityEvent(applications: socialActivitySelection.applicationTokens, categories: socialActivitySelection.categoryTokens, webDomains: socialActivitySelection.webDomainTokens, threshold: DateComponents(minute: 2)) let events: [DeviceActivityEvent.Name: DeviceActivityEvent] = [.socialScreenTimeEvent : event] do { activityCenter.stopMonitoring([.socialScreenTime]) /// Tries to start monitoring the activity using the specified schedule and events. try activityCenter.startMonitoring(.socialScreenTime, during: schedule, events: events) } catch { /// Prints an error message if the activity could not be started. print("Could not start monitoring: \(error)") } } If there are any known workarounds or potential solutions, please share them. Thank you for your help in resolving this problem.

I am facing an issue while codesigning the Content/MacOS executable. The executable name is exactly similar to the .app file, and the signing certificates have not expired yet. Steps followed to generate signed files: Executed codesign on files within the .app folder. Then executed codesign on the .app folder. Tried to notarize with the new notarization tool. Do we have to sign each individual file and folder? Observations: .DS_Store files were removed from the .app before signing. Another app with the same certificate is able to sign correctly. Content/MacOS contains multiple files, including the app executable. These files are signed except the main executable. same installed_app after copying at another location showing signed.

I'm working on an in-house iOS app designed to help users accurately track their routes during trips. Currently, I've implemented a method to track users when the app is open in the background. However, I'm facing challenges, as the tracking stops when the device is locked for more than 10 minutes. I'm looking for a solution to continuously track a user's geolocation, even if the app is closed or not in use. Specifically, I want to ensure uninterrupted tracking, especially when the device is locked. Here are some key points: Current Method: I'm currently using the Core Location method and a combination of background tasks and a repeating timer to fetch the user's location and update a log for geolocation tracking when the app is open in the background. Issues Faced: The tracking stops when the device is locked for more than 10 minutes. This limitation impacts the accuracy of the route tracking during longer trips. Objective: My goal is to achieve continuous geolocation tracking, even when the app is closed or not actively used, to provide users with a seamless and accurate record of their routes. Platform: The app is developed for iOS using the .net maui platform, and I'm seeking solutions or suggestions that are compatible with the iOS .net maui environment. If anyone has experience or insights into achieving continuous geolocation tracking on iOS, especially when the app is not in use or the device is locked, I would greatly appreciate the assistance.
