Nearby Accessory
Can the vehicle‑side UWB module, acting as a Nearby Accessory, perform ranging with multiple iOS phones simultaneously while iOS cell uses background ranging with the vehicle‑side UWB (which involves BLE GATT services)? I mean, when the IOS cell works in the background, it will read the nearby gatt characteristic automatically. If there were multiple phones perform ranging with the accessory, the read characteristic from the accessory side, what shall its content be? Or does the accessory only perform ranging with one phone at a time?

Icon looks broken on the App Store
Hi, I just had V1.0 of my app approved on the App Store and I immediately noticed that the icon preview is broken. It looks good in Xcode, on-device and also in the App Store link preview. The icon was built with Icon Composer. Here's the difference (left is App store): Has anyone encountered the same issue and found a solution?

Guideline 5.2.5 - Legal - Intellectual Property
Your app still contains features that mimic the iOS interface or behavior. I have a simple app that uses a NavigationSplitView 3 panels I have a section for Filters and User created Categories in Panel 1 A list of "Requests" from the selected Filters/Categories in Panel 2 and details of a request in Panel 3 It's designed to be simple and easy to use. How can it NOT "mimic the iOS interface" if I am using their own APIs? What should I do to get around this

Feedback on the new Camera app icon in iOS 26
I’m currently using the iOS 26 Developer Beta and noticed the new icon design for the Camera app. Personally, I preferred the previous icon it looked cleaner, more elegant, and felt more in line with Apple’s signature iOS design language. The new icon feels more like something you’d expect from Android. It lacks the minimalist, refined style that usually defines iOS icons. I understand UI evolves over time, but this change feels like a step away from what makes Apple’s design philosophy unique. Just wanted to share this honest feedback as a long-time user and developer. Thanks for considering!

Need Help Moving INRx App to New Developer Account – Design Issue Blocking Submission
Hello Apple Developer Support, We initially uploaded our INRx App on a different Apple Developer account for internal testing purposes. Now, we would like to publish the same app under a new Apple Developer account for production, but we're currently facing a design-related rejection during the review process. We believe the app meets all guidelines, and there were no design issues flagged previously when submitted from the testing account. Could you please help us understand: Why the same app is now being rejected for design issues? Is there a way to resolve this while moving the app to the new account? Any advice or clarification would be greatly appreciated so we can successfully proceed with publishing. Thank you!

App crashes on click NEXT to next View
I am developing an app in Swift Playground (No Xcode). All my Views respond to the navigation call when I click NEXT except one. When I click NEXT the app hangs then crashes. The error message does not identify the cause of the crash. I have research every possible lead with no success. I would like to get some ideas on how to resolve this issue.

Suggestions on macOS and iPad app structure
Building an app to edit the various parameters of digital musical instruments. A typical user would have perhaps max 6 instruments, out of the hundreds of possibilities. Would like to structure the app with a global window, menu, etc which would be a free download. The user could download editor inserts for their particular set of instruments and ignore all of the others. The downloaded editors would show as options in a menu. It seem like more than a widget but less than a library. Building a monolithic app containing all possible editors doesn't seem like an option, but separate full-app editors for each piece of gear doesn't sound right either. Any suggestions out there? Thanks very much Brian

Images added in Reality Composer look darker in AR
I’m working with Reality Composer and noticed that images added directly to a scene appear significantly darker when viewed in AR. This seems different from how other objects in the scene respond to lighting, especially under varying real-world light conditions. Is this expected behavior? Are images treated with a different lighting model in Reality Composer? Is there any recommended way to get more consistent light response for image-based artworks?

How can I set up a B2B subscription with ABM + MDM + Paywall
I am looking for guidance on how people have solved this problem/use case. What is the best way to structure a seat based subscription app that an organization can pay for seats for all their users, can be distributed via mdm or via app store and is easy (low friction) to get paid for and started for small companies? I market to a business to buy my app, they want it installed on all 25 devices they have. They use ABM to acquire 25 licenses with and MDM to distribute. The app is currently free to download so ABM charges $0 but has a paywall to use. The paywall is a RevenueCat one and no user account is needed. All entitlements and free trial work great. When it is deployed to the 25 devices, they can either sign up with their own AppleId and own/company credit card, or use a company appleid and company card for all 25 devices to solve the issue but neither are great. Doubtful they would want to pay their money for a company required app on a company phone (don’t blame them). If they share an appleid, my MRR drops to 1/25th since they will just share the purchase. Any suggestions would be greatly appreciated.

Rendering Multi-Page PDF with SwiftUI View
I have the following code that renders a one-page PDF: func render() -> URL { let renderer = ImageRenderer(content: pdfView()) let url = URL.documentsDirectory.appending(path: "filename.pdf") renderer.render { size, context in var document = CGRect(x: 0, y: 0, width: 2550, height: 3300) guard let pdf = CGContext(url as CFURL, mediaBox: &document, nil) else { return } pdf.beginPDFPage(nil) context(pdf) pdf.endPDFPage() pdf.closePDF() } return url } func pdfView() -> some View { Text("View") } How can this be modified so that it renders a PDF with more than one page?

What is the best way to design a UITabBarController (or Sidebar) combined with a UISplitViewController on iPadOS 18 and later, while avoiding memory management issues?
I'm developing an iPadOS 18+ application that uses a UITabBarController, styled as a sidebar, to serve as the primary navigation interface. This setup includes 20 different tabs, each representing a distinct section of the app. For the user experience, each tab needs to present a master-detail interface, implemented using a UISplitViewController. The goal is to allow users to navigate between tabs via the sidebar, and within each tab, access related content through the split view's list-detail pattern. The Problem: Currently, my implementation involves instantiating a separate UISplitViewController for each tab, resulting in 20 unique split view instances embedded inside the UITabBarController. While this works functionally, it leads to significant memory usage, especially after the user opens each tab at least once. The accumulation of all these instantiated view controllers in memory eventually causes performance degradation or even memory warnings/crashes on lower-end iPads. The Question: What is the best approach to implement this type of architecture without running into memory management issues? Specifically: Is there a way to reuse or lazily load the UISplitViewController instances only when needed? Can we unload or release split view controllers that haven't been used for a while to reduce memory pressure? Would a custom container controller be more appropriate than using UITabBarController in this case? Are there iPadOS 18+ best practices or newer APIs that support this kind of complex multi-tab, multi-split-view structure efficiently? Any advice on how to optimize memory usage while preserving the sidebar navigation and split view layout would be highly appreciated.

How can I force a function only runs once during the whole app lifecycle?
Hi, I want to generate some sample datas for demonstrating the functions of my app when the app launched. My codes are as followings: func generateSampleData() { let hasLaunchedKey = "HasLaunchedBefore" let defaults = UserDefaults.standard if !defaults.bool(forKey: hasLaunchedKey) { //generate the demo data } defaults.set(true, forKey: hasLaunchedKey) } And I put the func in a view's onAppear modifier. I found every time I go the view, it generates the demo data again, which results in producing a lot of demo data. But I have set the status of the function running in the userdefault. Why did it happen? Best Wishes,

IS THE SWiPE LEFT CAMERA MODE REALLY IMPORTANT?
I have really examined the swipe left Camera function mode and sincerely believe it is no more important especially when there no option in the settings to turn it on or off. I will highly recommend a total scrap in the iOS 26 or if possible a function to activate and deactivate it.

NFC Bottomsheet customization
Hi all, I wanted to check whether the NFC bottom-sheet UI shown by iOS during an NFC reading session can be customized. We have a Figma design (attached) for how the sheet should look, but we are not sure whether iOS allows modifying the default NFC UI. Is UI customization supported, or is the bottom sheet fully controlled by the system? Thanks in advance.

macOS 26 Beta Dark Mode Icons Fallback Removed
Post: In macOS 26 Betas 1–3, the system applied an automatic dark-mode fallback for app icons. This ensured consistency across the Dock and Finder even when developers hadn’t provided dark assets. Since Beta 4, this fallback was removed. As of Beta 7, icons now rely entirely on developer-updated assets. The result is mixed light and dark icons in the Dock, breaking visual consistency and making app recognition slower in dark mode. Observed behavior: • Icons without dark assets are displayed in their original light version. • Some apps (e.g. Final Cut Pro) show a gray border treatment that feels inconsistent with the rest of the UI. • The fallback applied in Betas 1–3 is completely absent. Expected behavior: System should provide a fallback rendering until developers supply proper dark assets, or offer a toggle in System Settings → Appearance (e.g. “Force Dark Icons”). This is still present in Beta 7. Is there any plan to restore the fallback mechanism or provide a user option?

Categorize Contacts
I would really like to be able to categorize my contacts. I work for a grocery store and have contacts from various companies. I would like to be able to categorize them by company or group them as I see fit. Currently, I don't see a way to do this. Please add this in a future update. Having all contacts just alphabetically is not efficient enough. Also, I would like to be able to manually adjust the size of widgets. i.e. If I want more stocks to be visible, I would like to be able to lengthen the height/width of the widget beyond what it currently allows to view more information. Thank you. If you have any follow-up questions, please let me know. Torrey

Design Challenges with persistent toast message
I have an ongoing activity in progress. Think of: a delivery in progress house internet reboot in progress some water / electricity / internet / tv outage. (food) order processing I want to show a persistent toast message above the tab bar, across all tabs and screens across the app. It could take 15 minutes until the activity is finished. Obviously there's a challenge of: accessibility content overlaying with each other extra engineering effort. What we've thought of doing is: Option1: show a toast message, but when a modal is presented then it presents on top of the toast message. The toast message no longer updates itself. Once the modal is finished, then the toast message re-appears and continues to update. Option2: keep the toast message across all tabs and modals and work through the challenges mentioned Question: What are some other design approaches that could be taken to persist an ongoing activity (much like 'Live Activity', but just across the app when it's in foreground) or what are some design reasons that the two options considered are bad?

Are there iPadOS 18+ best practices or newer APIs that support this kind of complex multi-tab, multi-split-view structure efficiently? Any advice on how to optimize memory usage while preserving the sidebar navigation and split view layout would be highly appreciated.

How can I force a function only runs once during the whole app lifecycle?
Hi, I want to generate some sample datas for demonstrating the functions of my app when the app launched. My codes are as followings: func generateSampleData() { let hasLaunchedKey = "HasLaunchedBefore" let defaults = UserDefaults.standard if !defaults.bool(forKey: hasLaunchedKey) { //generate the demo data } defaults.set(true, forKey: hasLaunchedKey) } And I put the func in a view's onAppear modifier. I found every time I go the view, it generates the demo data again, which results in producing a lot of demo data. But I have set the status of the function running in the userdefault. Why did it happen? Best Wishes,

IS THE SWiPE LEFT CAMERA MODE REALLY IMPORTANT?
I have really examined the swipe left Camera function mode and sincerely believe it is no more important especially when there no option in the settings to turn it on or off. I will highly recommend a total scrap in the iOS 26 or if possible a function to activate and deactivate it.

NFC Bottomsheet customization
Hi all, I wanted to check whether the NFC bottom-sheet UI shown by iOS during an NFC reading session can be customized. We have a Figma design (attached) for how the sheet should look, but we are not sure whether iOS allows modifying the default NFC UI. Is UI customization supported, or is the bottom sheet fully controlled by the system? Thanks in advance.

macOS 26 Beta Dark Mode Icons Fallback Removed
Post: In macOS 26 Betas 1–3, the system applied an automatic dark-mode fallback for app icons. This ensured consistency across the Dock and Finder even when developers hadn’t provided dark assets. Since Beta 4, this fallback was removed. As of Beta 7, icons now rely entirely on developer-updated assets. The result is mixed light and dark icons in the Dock, breaking visual consistency and making app recognition slower in dark mode. Observed behavior: • Icons without dark assets are displayed in their original light version. • Some apps (e.g. Final Cut Pro) show a gray border treatment that feels inconsistent with the rest of the UI. • The fallback applied in Betas 1–3 is completely absent. Expected behavior: System should provide a fallback rendering until developers supply proper dark assets, or offer a toggle in System Settings → Appearance (e.g. “Force Dark Icons”). This is still present in Beta 7. Is there any plan to restore the fallback mechanism or provide a user option?

Categorize Contacts
I would really like to be able to categorize my contacts. I work for a grocery store and have contacts from various companies. I would like to be able to categorize them by company or group them as I see fit. Currently, I don't see a way to do this. Please add this in a future update. Having all contacts just alphabetically is not efficient enough. Also, I would like to be able to manually adjust the size of widgets. i.e. If I want more stocks to be visible, I would like to be able to lengthen the height/width of the widget beyond what it currently allows to view more information. Thank you. If you have any follow-up questions, please let me know. Torrey

Design Challenges with persistent toast message
I have an ongoing activity in progress. Think of: a delivery in progress house internet reboot in progress some water / electricity / internet / tv outage. (food) order processing I want to show a persistent toast message above the tab bar, across all tabs and screens across the app. It could take 15 minutes until the activity is finished. Obviously there's a challenge of: accessibility content overlaying with each other extra engineering effort. What we've thought of doing is: Option1: show a toast message, but when a modal is presented then it presents on top of the toast message. The toast message no longer updates itself. Once the modal is finished, then the toast message re-appears and continues to update. Option2: keep the toast message across all tabs and modals and work through the challenges mentioned Question: What are some other design approaches that could be taken to persist an ongoing activity (much like 'Live Activity', but just across the app when it's in foreground) or what are some design reasons that the two options considered are bad?
