Overview

I have created a simple scene in reality composer (composer not composer pro). It contains just a cube and text item. I convert this to usdz file and load it into a Arkit swift app. Since ios 18/xcode 16 - the "text" element is not displayed at all. The cube is displayed, anchors correctly and can be moved etc....

Hi everyone, I was exploring the Display Distinct Layouts Per Section section of the Apple documentation and noticed a potential issue in the example code provided. Specifically, in the createLayout method of the TwoColumnViewController in the sample project, the item size appears to be incorrectly described. The documentation states that the item size is ignored because the items are organized in columns, but in practice, the size is considered. When running the sample project without any modifications, the layout doesn't behave as described or expected. Here’s what I observed: The items are not displayed as intended in a two-column layout. Modifying the item size explicitly affects the layout, contrary to the documentation's claim that the size is ignored. This seems to be a mismatch between the documentation and the actual implementation. Could this be clarified or corrected? Has anyone else encountered this issue? If so, are there any recommended adjustments to the sample code to achieve the intended layout? Thanks in advance for any insights or updates on this! https://developer.apple.com/documentation/uikit/views_and_controls/collection_views/implementing_modern_collection_views#4461906

We use File Provider Extension in our main app, and it is working fine. We always call "NSFileProviderManager.add(_:completionHandler:)" function to start the extension, and "NSFileProviderManager.disconnect(reason:options:completionHandler:)" to temporarily quit the extension with the reason which will be shown in the Finder at the top of the FP domain folder. But sometimes, when the main app calls the above functions, the following issue cases occur, and the extension does not start/stop: The completionHandler function doesn't get called (As we noticed, we waited for 2 minutes. Then, we restarted the main app.) One of the following errors returned: i) "The application cannot be used right now", ii) "Couldn't communicate with the helper application", iii) "No valid file provider found with identifier" Here, the important thing is that restarting the main app once or twice clears the issue, and the extension starts. But it is frustrating to restart the app each time we get this issue. We want to know the following things: Why and when do the above issues occur? Why do they occur only sometimes, and how does the app restart clear the issue? How do we resolve them without restarting the main app? This has become a critical issue, so a detailed explanation would be greatly appreciated. TIA.

The build status has a green check in Xcode Cloud, but TestFlight see no builds and suggest that I submit one. Then it provides a link to an incredibly unhelpful list of upload tools, at least one of which suggests creating a developer account!!!

After upgrading to IOS 18.1.1 CarPlay became terrible. During music playback via USB cable the subwoofer stopped working. Bass is not heard. Sound became very poor. It is impossible to exit CarPlay by pressing the button on the multimedia. if I Disconnect the cable from the phone - the multimedia (radio) works fine again and the subwoofer works normally. CarPlay blocks pressing the keys on the multimedia system. Also it is not possible to update the multimedia, because multimedia menu is inaccessible. When I connect the phone via Bluetooth the timer on the multimedia screen immediately starts, as if I am talking on the phone to somebody. Sound quality via Bluetooth is even worse than via USB. Listening to music (the main function) has become impossible. Please fix this problem. Thank you very much!

Multiple times a day, every time I open a new window for forums.developer.apple.com, if I'm signed in, it asks me if I want to opt in to notifications. Even if I click on the opt in button. I've just reproduced it five times in a row here. What is going on?

Hi everyone, I’m facing an issue with setting Azerbaijani as the default language for my app. The app is designed specifically for the Azerbaijani market, where the primary language is Azerbaijani, although Russian is also widely spoken. During the submission process, I couldn’t find an option to set Azerbaijani as the default language. To move forward, I selected Russian, assuming I could change it later. However, I’ve hit a roadblock—I can’t figure out how to make Azerbaijani the default language now. Has anyone else encountered this problem? Is there a workaround or solution to enable Azerbaijani as the default language? I’d greatly appreciate any advice or guidance from the community. Thanks in advance!

Ref- https://support.apple.com/en-in/guide/deployment/dep3b4cf515/web When we deploy an Payload with identifier "com.apple.airprint" , It will add the deployed printer configurations to printers list in mac. Which additionally needs the mac user to add it from Settings -> Printers -> Add Printer -> (Deployed Printer Configuration will be listed here) Select the printer -> Click Add . Screenshot where user need to add it manually after profile association is attached below. Now the Printer is available to be used ,when an share option in any document is clicked. Why this flow requires multiple to and fro. Can it be able to deploy the printer straight to Printers available List instead of manually adding from the above screenshot

Hi, every one! I'm trying to bind timeline(animation + audio) and behaviors on an entity in reality composer pro. In xcode, I need to clone this entity and use the behavior, but I found that the behaviors are not clone(send notification but not received by reality composer pro and not execute the timeline). How can I solve this problem? Thanks!

I am currently working on implementing the Live Caller ID Extension for my iOS app, and I understand that a backend server is required for this functionality. While I’ve gone through Apple’s documentation, the details on the backend setup are limited and not very clear for my backend team to implement it effectively. Could someone provide a more detailed explanation or sample implementation of the backend server required for this extension? Specifically, we are looking for: A clear understanding of the APIs and endpoints the backend needs to expose. Any authentication mechanisms required for communication with the extension. Data format (e.g., JSON structure) for requests and responses. Example code or additional resources, if available. Any help or guidance in understanding the exact backend requirements would be greatly appreciated.

Hello all, I recently submitted my app to the App Store, but it was rejected due to the "design spam" guideline, stating that it duplicates content and functionality in the saturated astrology category. My app primarily focuses on astrology but includes a unique AI-powered feature that I believe differentiates it from others in the category. Specifically, it leverages AI to provide highly personalized insights and interactive features that go beyond typical horoscope apps. Also it has a social media side that let people communicate and discuss about astrology. How can I better communicate my app’s unique value to the App Review team? Are there specific design or content tweaks that could help it stand out more clearly? Has anyone successfully appealed a similar rejection? If so, what approach worked for you?

While reading the developer documentation article Adopting SwiftData for a Core Data App, one particular line piqued my interest. For apps that evolve from a version that doesn’t have any app group container to a version that has one, SwiftData copies the existing store to the app group container. Given how troublesome it has been to migrate the Core Data persistent store to an app group container, I decided to try this out myself. I created an Xcode project using the default Core Data template. I then added a few Item objects with timestamps. There, I had what we would consider a regular Core Data app. I then created a widget extension for this app since this is one of the most common uses for adopting an app group in an Xcode project. After that, I linked the main target with the widget extension using an app group. In the widget extension, I tried to fetch the Item objects. I utilized the SwiftData code in the sample project associated with the article above. struct Provider: TimelineProvider { private let modelContainer: ModelContainer init() { let appGroupContainerID = "group.com.genebogdanovich.CoreDataSwiftDataAppGroup" guard let appGroupContainer = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: appGroupContainerID) else { fatalError("Shared file container could not be created.") } let url = appGroupContainer.appendingPathComponent("CoreDataSwiftDataAppGroup.sqlite") print("\(url)") do { modelContainer = try ModelContainer(for: Item.self, configurations: ModelConfiguration(url: url)) } catch { fatalError("Failed to create the model container: \(error)") } } } func getTimeline(in context: Context, completion: @escaping (Timeline<Entry>) -> ()) { Task { @MainActor in let fetchDescriptor = FetchDescriptor<Item>() let items: [Item] = try! modelContainer.mainContext.fetch(fetchDescriptor) print(items) let entry = SimpleEntry(date: .now, emoji: "😀", count: items.count) let timeline = Timeline(entries: [entry], policy: .never) completion(timeline) } } The fetch yielded no results. However, as I explored the app group directory in the file system, I found a .sqlite file. That is interesting because SwiftData creates .store files by default. So, I am guessing that SwiftData did copy something. Or the ModelContainer initializer just created another empty SQLite file since the fetch returned zero results. I would highly appreciate someone elaborating on that quote from the documentation.

I have opened the Push Notification and the Broadcast Capability at developer Capabilities, but when I call the api https://api-manage-broadcast.sandbox.push.apple.com:2195/1/apps/already change to my Identifiers/channels, I always got the "TopicMismatch". Did I set something wrong somewhere?

It's been more than 4 days since I create my developer's account and payments been successful but I still haven't recieved any instigation on the enrolment completion. How long does it usually take?

Hi, I have built an app for my company where we are providing users to purchase our food bars via the app and then what they purchase , we will deliver to people in conflict effected or disaster effected areas. The purchase is done via stripe and apple pay. The food bars are made of Spirulina and is full of energy and protein. Currently this is available via our web platform. My app was rejected as my company is not a recognized non profit. I would like to know how I can get my app approved. The only viable option given for me via app review was to take my payment screen to a web platform as donations. However I would like to know if the issue is that the app is making users believe they are donating, by me changing the wordings, images , and structure of the app to ensure users know that they are purchasing the food bars and we are only delivering, will is help is app being approved by app store review.

There seems to be an issue in iOS 18 / macOS 15 related to image thumbnail generation and/or HEIC. We are transcoding JPEG images to HEIC when they are loaded into our app (HEIC has a much lower memory footprint when loaded by Core Image, for some reason). We use Image I/O for that: guard let source = CGImageSourceCreateWithURL(inputURL, nil), let destination = CGImageDestinationCreateWithURL(outputURL, UTType.heic.identifier as CFString, 1, nil) else { throw <error> } let primaryImageIndex = CGImageSourceGetPrimaryImageIndex(source) CGImageDestinationAddImageFromSource(destination, source, primaryImageIndex, nil) When we use CGImageDestinationAddImageFromSource, we get the following warnings on the console: createImage:1445: *** ERROR: bad image size (0 x 0) rb: 0 CGImageSourceCreateThumbnailAtIndex:5195: *** ERROR: CGImageSourceCreateThumbnailAtIndex[0] - 'HJPG' - failed to create thumbnail [-67] {alw:-1, abs: 1 tra:-1 max:4620} writeImageAtIndex:1025: ⭕️ ERROR: '<app>' is trying to save an opaque image (4620x3466) with 'AlphaPremulLast'. This would unnecessarily increase the file size and will double (!!!) the required memory when decoding the image --> ignoring alpha. It seems that CGImageDestinationAddImageFromSource is trying to extract/create a thumbnail, which fails somehow. I re-wrote the last part like this: guard let primaryImage = CGImageSourceCreateImageAtIndex(source, primaryImageIndex, nil), let properties = CGImageSourceCopyPropertiesAtIndex(source, primaryImageIndex, nil) else { throw <error> } CGImageDestinationAddImage(destination, primaryImage, properties) This doesn't cause any warnings. An issue that might be related has been reported here. I've also heard from others having issues with CGImageSourceCreateThumbnailAtIndex.

Hi. I have reviewed the process of integrating Apple Pay on the web, but I still don’t understand how to implement it. For example: I currently have software A and a payment website that my software provides to restaurants. So, how can I integrate Apple Pay on the restaurants' payment websites? I read that to integrate, we need to register for a Merchant ID with Apple Pay. So, is it the restaurants or the software provider who should register? Each restaurant will have a different website domain -> does that mean when registering the Merchant ID, the website domain is the payment website of each restaurant? When Apple Pay provides the verification file, the sales software (i.e., the payment website) must help the restaurants upload that file to the payment website of each restaurant, right? To verify if it is valid or not depends on Apple Pay, right? If it is valid, the Apple Pay payment button will be displayed, correct?

I have tried to initialize service workers, but they only work in the WebView. When I open an iframe from that WebView, they do not function. Below is my implementation. Is this an issue because iOS does not support service workers in iframes? Please help me answer this. :man-bowing: self.addEventListener('install', event => { // Apply this service worker immediately self.skipWaiting(); }); const putInCache = async (request, response) => { const cache = await caches.open("v1"); await cache.put(request, response); }; const customCache = async ({ request, preloadResponsePromise }) => { }; self.addEventListener("fetch", (event) => { event.respondWith( customCache({ request: event.request, preloadResponsePromise: event.preloadResponse, }), ); });
