App Review Rejection – Guideline 2.1: “Create PIN” Not Responsive on iPad (iPhone-Only App)
Hi everyone, I’m looking for clarification regarding an App Review rejection under Guideline 2.1 – Performance – App Completeness. Apple reported the following issue: Bug description: “Create PIN” button was not responsive Review device: iPad Air 11-inch (M3) OS version: iPadOS 26.2.1 What’s confusing is the following: Observed behavior on our side The app has been tested extensively on: Multiple iPhone models iPad devices (including recent iPadOS versions) In all our testing: The Create PIN button is responsive The tap action triggers correctly The flow completes without errors At this point, we are unable to reproduce the issue described by App Review on either iPhone or iPad. iPhone-only intent vs iPad review The app is designed and optimized for iPhone usage only. However, the review was performed on an iPad device. If an app is available for download on iPad, is it always expected to function fully on iPad regardless of being phone-optimized? If iPad support is not intended, is explicitly disabling iPad

Reply to Can I disable a SwiftUI View from being a draggable source, but still leave it enabled as a dropDestination?
Sorry for the delay, I didn't get the notification. Thanks for the code, I would recommend to add a link to a focused project where I can download and play with it as of course without the images nor drop targets is hard to see what you are trying to accomplish and will help many developers here figure it out. Customize the drag preview to make the interaction more intuitive. You can modify the draggable modifier .draggable(player, preview: { VStack { Image(jersey) .resizable() .frame(width: 50, height: 50) if let player = content.player { Text(player.last) .font(.caption) } } }) Currently, the drop handler just prints the item. You might want to update the CellContent's player based on the drop? .dropDestination(for: String.self) { items, location in if let firstItem = items.first { print(Dropped: (firstItem)) // Update player logic here if needed // e.g., content.player = updatedPlayerBasedOn(firstItem) } return true } Looking forward to your focused sample. That'll help us better understand what's

Reply to MacOS(Apple Silicon) IOKit driver for FPGA DMA transmission, kernel panic.
Using gen32IOVMSegments() will return kIOReturnMessageTooLarge. If I don't set the maximum value of 8M, the result will still be the same, so I think it may not be related to the maximum value. If you haven't already, take a look at my post here. I haven't checked the code to confirm, but I strongly suspect that calling gen32IOVMSegments with a mask of the wrong size (like 0xFFFFF000) will cause kIOReturnMessageTooLarge, as the true mask range you've specified (0x00000000FFFFF000) is too large to fit in 32 bits. Does Apple M silicon not allocate <=32-bit bus addresses to third-party PCIe devices (FPGA)? Quite the opposite. We've actually gone to considerable trouble to ensure that we COULD provide 32-bit addresses to the PCI bus. Quoting Address Translation on 64-Bit System Architectures: Apple solved the problem with address translation which “maps” blocks of memory into the 32-bit address space of a PCI device. In this scheme, the PCI device still sees a 4-gigabyte space, but that space can be made up of

Reply to Crash/Exception thrown in UITableView initialization stack
Thanks for the post. I love crash files and you came to the correct place as they are better developers here that can help you with a crash. The interesting issue is that is crashing on swift core lib? However will be a great idea you follow this recommendations to post a crash file with all the information that can help them figure it out. Kindly submit a comprehensive crash report, adhering to the guidelines outlined in Posting a Crash Report. https://developer.apple.com/forums/thread/688669 Have you test it with iOS 26.2? In my modest opinion and without code nor much besides the header, the crash you're encountering, suggests that there might be an attempt to access memory that's either invalid or no longer valid. Ensure that the object or table or table items managing the isn't being deallocated prematurely. Any strong reference cycles or unintentional over-release could lead to accessing a dangling pointer. If the table view is being loaded from a storyboard or XIB, ensure there are no mismatch

Reply to .glassProminent leading toolbar item animation issue on push navigation
Thanks for the post and great customization. This is a complete post, with code and the great screenshot showing the results.I hope other engineers jump in this thread as well to provide their opinion. Based on your description and the provided code, it does seem like this could either be an unintended side effect of recent changes in iOS 26? You said you have a project showing this? Have you tried it in Xcode 26.2 and 26.3 beta? As you've mentioned is no advised against tinting or customizing toolbar items extensively. Double-check to ensure that your use case aligns with their guidance, as deviations might lead to inconsistent behaviors or future compatibility risks. Make sure that your testing device or simulator is running the latest version of iOS 26.2. What version of iOS are you running? I always recommend to use a plain with custom styling that mimics the glass effect. I don’t think yet this is a bug, but let’s invite other engineers and good deeper on what versions

Abnormal Background Delivery Frequency of HealthKit on Specific watchOS Devices
1/ Issue Summary In our application, we use HKObserverQuery together with:HKHealthStore.enableBackgroundDelivery(for:frequency: .immediate) to enable HealthKit Background Delivery, allowing the system to wake our App Extension in the background to process health data updates. Under the same app build, identical HealthKit permission configuration, and the same watchOS version, we have observed significant differences in background delivery frequency across different devices. Specifically, on certain devices (e.g. Apple Watch Series 10, watchOS 26.2.1), the background delivery frequency is significantly reduced, behaving as if it is capped at approximately once per hour. On other control devices, under the same configuration, background delivery is triggered much more frequently and consistently, at approximately every 8–16 minutes. This behavior is consistently reproducible on the affected devices. **We would like to understand whether there are any officially recommended implementation patterns, best

How to apply for Reader App / External Link Account Entitlement?
Hello, I’m developing an educational iOS app called “Lipi – Punjabi Kids Learning” that delivers pre-created educational content using a subscription model, similar to how Netflix or Kindle deliver content. Users subscribe on our website, and the iOS app provides access to that subscribed content only. No digital content or subscriptions are purchased inside the iOS app. I’m trying to apply for the Reader App / External Link Account Entitlement, but I’m unable to find a dedicated application form. The previously referenced URL (developer.apple.com/contact/request/reader-app/) no longer works. Could someone from Apple or the community please confirm the current and correct process to request this entitlement? App details: App Name: Lipi – Punjabi Kids Learning Bundle ID: com.app.meriLipi Category: Education Content: Video lessons, live classes, quizzes, and writing exercises Website: https://merilipi.com Pricing: https://merilipi.com/pricing I’ve already contacted Apple Deve

Severe Frame Drops When Resizing macOS Window with Dynamic LazyVGrid
Context: I am building a macOS file (currently image only) browser using SwiftUI. The core view is a ScrollView containing a LazyVGrid. The layout is dynamic: as the window resizes, I calculate the optimal number of columns and spacing using a GeometryReader. The Issue: While scrolling is pretty smooth (thanks to custom image caching and prefetching), window resizing is significantly laggy. After having scrolled the UI stutters and drops frames heavily while dragging the window edge. The Code: https://github.com/MorusPatre/Binder

CKShare(rootRecord:) Returns Share with Nil Root Even When All CloudKit Best Practices Followed (iOS 26.2.1)
I’m seeing an issue with CloudKit sharing in iOS 26.2.1: When I call CKShare(rootRecord:) with a brand-new record in a fresh custom zone, the share is created with no root attached (rootFromShare == nil). After saving both the root and share in a single CKModifyRecordsOperation, fetching the share from the server still shows no root reference (rootRecordID == nil). No errors are thrown, but sharing simply fails. Key facts: • Custom zone created and confirmed (sharing enabled, capsRaw=7/15) • Brand-new record type and fresh IDs each run • Never reusing records or shares • Saving both root and share together in one operation • No default zone usage; always custom private zone Tested: • Multiple devices, iCloud accounts, and app versions • Both simulator and physical device Debug logs consistently show: • SHARE_CREATE_SHARE_LOCAL ... rootFromShare=nil • After save/fetch: rootRecordID=nil on server Has anyone seen this? Is there a new CloudKit regression in iOS 26.x, or am I missing som

Reply to SwiftUI can not find
Hi, The problems you are facing is due to the fact that you named your project SwiftUI. This is causing the build system to create a module for your app called SwiftUI which is the exact same module name that the system library is called. I expect you'd see these issues resolved if you rename your app to something that doesn't match one of the system frameworks.

Reply to UIApplication.canOpenURL not working without Safari
Thanks for your post and interesting on your comment about: Long press on the Safari icon and choose Remove app If you make the system avoid using Universal Links by telling how to handle the link. Since you mentioned universal links, make sure there's no conflict with any custom URL schemes defined in your app's . Universal links should ideally not interfere with opening URLs in a browser unless specifically set up to redirect to an app. 
Since you observed different behavior on iOS 26.0+, double-check whether this is related to a beta version or a specific OS bug. Review Apple's release notes or beta forums for any related issues and consider filing a bug report if necessary. Ensure you're testing on various devices and simulators, as sometimes configuration or environment-specific issues can cause unexpected behavior. But I’m wondering if you are disabling the link itself, you can see that on the swctutils file search for the link itse
