Need Help with Guideline 4.2 - Minimum Functionality
I recently got feedback for my app under Guideline 4.2 - Design - Minimum Functionality, and I’m a bit confused. Apple mentioned that the app isn’t “app-like” enough and doesn’t provide sufficient entertainment value or utility. However, I genuinely think my app is unique compared to others on the market. Most similar apps only offer basic features like scorekeeping and saving the game. My app goes beyond that by tracking detailed statistics based on the types of scores achieved during the game. At the end, there’s even a Player Ratings section, which enhances competition and makes the experience more fun for players. Additionally, in today’s gaming scene, many groups play the traditional 101 game with a reward and penalty system. My app uniquely incorporates a reward system, something no other app in the market currently offers. I believe my app has the potential to stand out and meet the needs of a wide audience. Has anyone faced similar feedback? Or does anyone have suggestions on how I could better address this issue? Thanks in advance! 😊

About tvOS Material (design resource)
I noticed a discrepancy between the Material specifications for tvOS on the Developer page and the naming in the Design Resources (Sketch files). Which one should we consider authoritative? https://developer.apple.com/design/human-interface-guidelines/materials

.onAppear and .task code not running
Hi, I have the following code, which for some reason is not working as expected. I have an .onAppear and a .task function that isn't running, which I can see isn't running because nothing is printing. Any guidance would be greatly appreciated. Thank you. struct ContentView: View { var body: some View { ZStack { switch view { case .view1: View1() case .view2: View2() case .view3: View3() case .view4: View4() case .view5: View5() default: SubscriptionStoreView(groupID: "") } } .onAppear() { view = .view6 print("test 1") } .task { print("test") await refreshPurchasedProducts() } } func refreshPurchasedProducts() async { // Iterate through the user's purchased products. for await verificationResult in Transaction.currentEntitlements { switch verificationResult { case .verified(let transaction): print("verified") case .unverified(let unverifiedTransaction, let verificationError): print("unverified") default: print("default") } } } }

How can this be resolved - load_eligibility_plist: Failed to open //private/var/db/os_eligibility/eligibility.plist: Operation not permitted(1)
I'm programming my constraints in my video game, which is working good so far until I ran into my most important interactive storyboard. I have three buttons that move back and forth on the Y position each time they are hit. The buttons Y positions only change to view.safeAreaLayoutGuide.centerYAnchor, constant: 100 or view.safeAreaLayoutGuide.centerYAnchor, constant: 200 or view.safeAreaLayoutGuide.centerYAnchor, constant: 300 The strange part is the button that is in the Y 100 stays visible and I can hit the button that is in the Y 100. The buttons in the Y 200 and Y 300 positions are visible until after one or two hits, then the button that is in Y 300 position disappears, then after another hit or two the button that is in the Y 200 position disappears but the button that is in the Y 100 is still visible. I cleared all my constraints to narrow it down to clear view of the constraints that is causing the problem. I do not think this Log Noise. Below is the error log: load_eligibility_plist: Failed to open //private/var/db/os_eligibility/eligibility.plist: Operation not permitted(1) 1 Unable to simultaneously satisfy constraints. Probably at least one of the constraints in the following list is one you don't want.

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!

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

SF Symbols Variable Draw without the background.
Is it possible to use the new variable draw feature for a custom SF Symbol without it leaving the background behind it when it is not drawn? I am trying to make a tally icon that is drawn with the variable draw, but it doesn't look good if the tally is visible in the background before it is drawn.

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?

Exception occurred during startRunning and stopRunning calls using AVCaptureSession
I called the viewWillDisappear method in UIViewController AVCaptureSession *session = self.session; dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{ if (!session.running) { [session startRunning]; } }); I called the viewWillDisappear method dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{ AVCaptureSession *session = self.session; if (session && session.running) { [session stopRunning]; } }); But when the user exits the background and returns to the current page, clicking 'Return' will cause an exception Abnormal information: #36 Thread SIGSEGV SEGV_ACCERR libdispatch.dylib _dispatch_source_set_timer + 32 one PrivacyAccounting 0x00000001a5ede000 + 533590244180685288 two PrivacyAccounting 0x00000001a5ede000 + 533590244180685288 three PrivacyAccounting 0x00000001a5ede000 + 1236823037899193652 four libdispatch.dylib 0x000000018ea01000 + 3414669699500290324 libsystem_pthread.dylib _pthread_wqthread + 14360117738498687264

New in SF Symbols 7: ipod.and.vision.pro.
Why? Why stop there? (Why not ipod.and.imacg3? applenewton.and.vision.pro?) I get why the older ipod symbols exist but these new pairings are odd. If anyone ever sees these restricted symbols in the wild, or even just someone using a Vision Pro and an iPod (Touch) together in a way that's not contrived, please do let me know!
