Overview

Hi, I tried to enroll since week ago, went thru the whole process, but now I'm stuck on "Enrollement not completed - You enrollment in the Apple Developper pogram could not be completed at this time." I opened a case (ID: 102869536459), but I haven’t received a response yet. What's next ?

Hi, I’m looking for clarification from folks familiar with CoreHID rather than App Review, as the guys there have not responded to my post (https://developer.apple.com/forums/thread/820676) We have a sandboxed macOS app that creates a virtual HID device (HIDVirtualDevice) as described in Creating virtual devices https://developer.apple.com/documentation/corehid/creatingvirtualdevices To work at all, the app requires the entitlement: com.apple.developer.hid.virtual.device With this entitlement present, macOS shows the system prompt requesting Accessibility permission App would like to control this computer using accessibility features. Grant access to this application in Security and Privacy preferences located in System Preferences. when HIDVirtualDevice(properties:) is called. There is no mention of Accessibility in the HIDVirtualDevice documentation, but the behavior is reproducible and seems unavoidable. My question is therefore: Is creating a virtual HID device from userspace via HIDVirtualDevice considered inherently incompatible with Mac App Store distribution? In other words: Is the Accessibility prompt an expected side‑effect of this API? And if so, does that mean using HIDVirtualDevice is only practical for direct (non–App Store) distribution unless the app is explicitly an accessibility tool? I’m not asking about review policy details—just whether, from a technical/system point of view, HIDVirtualDevice is actually intended to be usable by App Store apps. For context, there seem to be public, non‑accessibility uses of Apple’s virtual HID infrastructure, like this recent post: https://developer.apple.com/forums/thread/820708 and corresponding Github repo this project. I don't know if these intend to use the App Store, but they might end up in the same situation. Any insights from people who’ve worked with CoreHID would be greatly appreciated. Thanks, Magnus

Hello, I'm the developer of RPGPlayer, a game emulator for RPG Maker games that has been live on the App Store since 2025. I'm writing here out of frustration and desperation after 2+ months of trying to publish a critical bug fix update. The Situation I submitted v2.4 on February 21, 2026. Since then, I have received 9+ rejections under Guidelines 4.7 and 2.5.2. Every single rejection message is word-for-word identical — the same copy-pasted text, every time. None of my detailed technical responses have ever been acknowledged or addressed. I have submitted appeals twice through the App Review Board. Both times I received the same automated response: "The App Review Board will contact you directly once they've completed their investigation." The first appeal went unanswered for over 30 days. At this point, I genuinely do not believe a human being has opened my app during any of these reviews. The Technical Reality RPGPlayer is a game emulator, explicitly permitted under Guideline 4.7. The rejection under 4.7 states that "HTML5-based games appear to be an incidental feature." This is incorrect. RPG Maker MV/MZ games are built on HTML5/JavaScript by design — that is the engine's native architecture on all platforms including PC and consoles. The WKWebView is the emulation layer, not a web browser or game portal. There are zero bundled games. The rejection under 2.5.2 states the app "installed or launched executable code." The app does not download anything from the internet. It includes a bundled, statically-linked runtime (MKXP-Z) that interprets local game scripts from user-imported files — identical to how Delta Emulator interprets ROM instructions. The Double Standard Other apps on the App Store use the exact same architecture as RPGPlayer: Delta Emulator — approved under Guideline 4.7, interprets user-provided ROM files Quest Play — RPG Maker MV/MZ player, uses the same WebView approach, currently receiving updates ArkRPG — same engine, same architecture, also on the App Store and getting updates. These apps are approved and actively updated. RPGPlayer is being rejected with automated messages for doing the exact same thing. What I've Tried Detailed technical responses in Resolution Center — ignored Two App Review Board appeals — no meaningful response Contact Us support requests — automated replies Provided ROM files, video walkthroughs, and thorough App Review Notes — none of it acknowledged The Impact My users have been waiting 50+ days for a critical bug fix. Some have left negative reviews calling me a scammer because they think I abandoned the app. I haven't. I've been fighting this review process every single day. I have a Meet with Apple appointment scheduled. But I wanted to share this here as well — both to ask if anyone has faced a similar situation with emulator apps, and to document what is happening in case it helps other developers. Has anyone successfully resolved a 4.7 + 2.5.2 rejection for a legitimate emulator app? Any advice is welcome.

ID 6758008521, Dear App Review Team, I submitted my app review and it got rejected for inaccurate screenshot. I have revised the app screenshot and also resubmitted. But it has been 8 days and no response. We look forward to completing the review, thank you.

I'm seeing a critical issue where a custom CKRecordZone is consistently deleted server-side when a second iCloud account interacts with a zone-wide CKShare. I've reproduced this 20+ times across two days and have exhausted every client-side fix I can think of. Looking for guidance on what might be going wrong. Setup Container: iCloud.com.cohencooks (production app on App Store) Custom CKRecordZone in owner's private database Zone-wide CKShare(recordZoneID:) (iOS 15+ zone sharing) SwiftData with ModelConfiguration(cloudKitDatabase: .none) — no automatic CloudKit mirroring Acceptance via CKFetchShareMetadataOperation → CKContainer.accept(metadata) (no UICloudSharingController) Minimal reproduction // 1. Owner creates zone + share let zone = CKRecordZone(zoneName: "MyZone") try await privateDB.save(zone) let share = CKShare(recordZoneID: zone.zoneID) share[CKShare.SystemFieldKey.title] = "My Share" as CKRecordValue share.publicPermission = .readWrite let (results, _) = try await privateDB.modifyRecords(saving: [share], deleting: []) // 2. Owner pushes ~500 records to zone — all succeed // 3. Second user (different iCloud account) accepts share let metadata = try await container.shareMetadata(for: shareURL) try await container.accept(metadata) // 4. Owner's next CKFetchRecordZoneChangesOperation → zoneNotFound (code 26) // Zone is permanently gone. allRecordZones() confirms deletion. What I observe Three distinct failure patterns depending on configuration: Pattern 1 — publicPermission = .readWrite, no addParticipant: Zone dies instantly after acceptance. First push notification shows cloudkit.share changed (zone alive), second push notification returns zoneNotFound. The non-owner never successfully wrote anything. Pattern 2 — publicPermission = .none with explicit addParticipant: Zone survives acceptance and 2-3 minutes of bidirectional sync (non-owner pulls 578 records, pushes meal plans back). Then a push notification arrives and the zone is gone. This is dramatically better than Pattern 1 but still fails. Pattern 3 — Container destabilization after repeated testing: After 20+ create/delete cycles in one day, zones die from the owner's own push notifications — no second device involved at all. The container appears to enter an unstable state. What I've ruled out Hypothesis Test Result publicPermission = .readWrite Changed to .none + explicit addParticipant Zone survived longer but still eventually deleted Zone name tombstoning Tested 6 fresh names never used in this container All eventually deleted Non-owner writes causing deletion Gated ALL non-owner push methods (recipe, meal plan, grocery, photo, event) Zone still deleted database.save(share) vs modifyRecords Switched to modifyRecords(saving:deleting:) Zone still deleted NSPersistentCloudKitContainer interference Removed all Core Data CloudKit code Zone still deleted Double share acceptance Fresh app install, single acceptance only Zone still deleted Advanced Data Protection Neither account has ADP enabled Not the cause Programmatic vs system acceptance Tested both container.accept() and tapping share link Zone still deleted CloudKit Dashboard No ZoneDelete operation is visible in the logs. All operations are ZoneFetch, ZoneChanges, RecordQuery, RecordFetch. I do see EphemeralGroup operations targeting the custom zone — not sure what generates those. Comparison with working apps I compared my implementation with another app (Spotbook) that uses the exact same zone-wide CKShare(recordZoneID:) pattern with publicPermission = .readWrite and programmatic acceptance — and it works. The main difference is that app uses CKSyncEngine (iOS 17+) rather than raw CKFetchRecordZoneChangesOperation / CKModifyRecordsOperation. Could CKSyncEngine be handling something internally that prevents this issue? Questions Is there a known interaction between zone-wide CKShare(recordZoneID:) acceptance and zone lifecycle that could cause zone deletion? Does CKSyncEngine handle zone-wide sharing differently than manual CKFetchRecordZoneChangesOperation + CKModifyRecordsOperation? What generates EphemeralGroup operations in CloudKit Dashboard? Could these trigger a zone delete? After 20+ zone create/delete cycles in a container, is there a server-side rate limit or tombstone mechanism that would destabilize new zones? Is the custom programmatic acceptance flow (CKFetchShareMetadataOperation → container.accept()) fully supported for zone-wide shares, or does it require UICloudSharingController? Any guidance would be greatly appreciated. This is blocking multi-user functionality for our app (mesa, a meal planning app on the App Store). Single-user sync works perfectly — the issue only manifests when a second iCloud account is involved. Environment: iOS 18.4.1, Xcode 16+, Swift, SwiftUI

I'm using Xcode 26.4 for Swift development on macOS 26.4.1. It seems that the documentation for the "Foundation" framework has disappeared, possibly after an Xcode update (not the latest one). "Foundation" does not appear in the left-side list in the developer documentation window, and searching for "URLSession", "UndoManager" finds no result. Autocomplete for these classes works. Quick help on URLSession shows just "inherits from" and "conforms to", but no description and no link to a help page. I've tried deleting files in ~/Library/Developer so that it rebuilds the index, and also fully removing and reinstalling Xcode and rebooting, but nothing seems to solve it. Is there any way to get the full documentation back in Xcode.

I have a collection view that covers all the screen and it is scrolling behavior is paging. This collection view is embedded in a UIViewRepresentable and used in a SwiftUI app. The issue is that when users rotate the devices, sometimes the CollectionView.contentOffset get miscalculated and shows 2 pages. This is the code that I'm using for the collectionView and collectionViewLayout: class PageFlowLayout: UICollectionViewFlowLayout { override class var layoutAttributesClass: AnyClass { UICollectionViewLayoutAttributes.self } private var calculatedAttributes: [UICollectionViewLayoutAttributes] = [] private var calculatedContentWidth: CGFloat = 0 private var calculatedContentHeight: CGFloat = 0 public weak var delegate: PageFlowLayoutDelegate? override var collectionViewContentSize: CGSize { return CGSize(width: self.calculatedContentWidth, height: self.calculatedContentHeight) } override init() { super.init() self.estimatedItemSize = .zero self.scrollDirection = .horizontal self.minimumLineSpacing = 0 self.minimumInteritemSpacing = 0 self.sectionInset = .zero } required init?(coder: NSCoder) { fatalError("init(coder:) has not been implemented") } override func prepare() { guard let collectionView = collectionView, collectionView.numberOfSections > 0, calculatedAttributes.isEmpty else { return } estimatedItemSize = collectionView.bounds.size for item in 0..<collectionView.numberOfItems(inSection: 0) { let indexPath = IndexPath(item: item, section: 0) let attributes = UICollectionViewLayoutAttributes(forCellWith: indexPath) let itemOrigin = CGPoint(x: CGFloat(item) * collectionView.frame.width, y: 0) attributes.frame = .init(origin: itemOrigin, size: collectionView.frame.size) calculatedAttributes.append(attributes) } calculatedContentWidth = collectionView.bounds.width * CGFloat(calculatedAttributes.count) calculatedContentHeight = collectionView.bounds.size.height } override func layoutAttributesForElements(in rect: CGRect) -> [UICollectionViewLayoutAttributes]? { return calculatedAttributes.compactMap { return $0.frame.intersects(rect) ? $0 : nil } } override func layoutAttributesForItem(at indexPath: IndexPath) -> UICollectionViewLayoutAttributes? { return calculatedAttributes[indexPath.item] } override func shouldInvalidateLayout(forBoundsChange newBounds: CGRect) -> Bool { guard let collectionView else { return false } if newBounds.size != collectionView.bounds.size { return true } if newBounds.size.width > 0 { let pages = calculatedContentWidth / newBounds.size.width // If the contentWidth matches the number of pages, // if not it requires to layout the cells let arePagesExact = pages.truncatingRemainder(dividingBy: 1) == 0 return !arePagesExact } return false } override func invalidateLayout() { calculatedAttributes = [] super.invalidateLayout() } override func shouldInvalidateLayout(forPreferredLayoutAttributes preferredAttributes: UICollectionViewLayoutAttributes, withOriginalAttributes originalAttributes: UICollectionViewLayoutAttributes) -> Bool { guard let collectionView, #available(iOS 18.0, *) else { return false } return preferredAttributes.size != collectionView.bounds.size } override func invalidateLayout(with context: UICollectionViewLayoutInvalidationContext) { guard let customContext = context as? UICollectionViewFlowLayoutInvalidationContext else { return } if let collectionView, let currentPage = delegate?.currentPage() { let delta = (CGFloat(currentPage) * collectionView.bounds.width) - collectionView.contentOffset.x customContext.contentOffsetAdjustment.x += delta } calculatedAttributes = [] super.invalidateLayout(with: customContext) } override func prepare(forAnimatedBoundsChange oldBounds: CGRect) { super.prepare(forAnimatedBoundsChange: oldBounds) guard let collectionView else { return } if oldBounds.width != collectionView.bounds.width { invalidateLayout() } } override func targetContentOffset(forProposedContentOffset proposedContentOffset: CGPoint) -> CGPoint { guard let collectionView, let currentPage = delegate?.currentPage() else { return .zero } let targetContentOffset = super.targetContentOffset(forProposedContentOffset: proposedContentOffset) let targetPage = targetContentOffset.x / collectionView.frame.width if targetPage != CGFloat(currentPage) { let xPosition = CGFloat(currentPage) * collectionView.frame.width return CGPoint(x: xPosition, y: 0) } return targetContentOffset } // This function updates the contentOffset in case is wrong override func finalizeCollectionViewUpdates() { guard let collectionView, let currentPage = delegate?.currentPage() else { return } let xPosition = CGFloat(currentPage) * collectionView.bounds.width if xPosition != collectionView.contentOffset.x { let offset = CGPoint(x: xPosition, y: 0) collectionView.setContentOffset(offset, animated: false) } } } The full implementation is attached in the .txt file: RotationTestView.txt

When using the official Wi-Fi Aware demo app on iOS, with the iOS device configured as a NAN Subscriber, after successfully establishing a peer-to-peer connection with another device via Wi-Fi Aware (NAN), the network path object nwPath.availableInterfaces does not list the nan0 virtual network interface. The nan0 interface is the dedicated NAN (Neighbor Aware Networking) interface used for Wi-Fi Aware data communication. Its absence from availableInterfaces prevents the app from correctly identifying/using the NAN data path, breaking expected Wi-Fi Aware data transmission logic. log: iOS works as subscriber: [onPathUpdate] newPath.availableInterfaces: ["en0"] iOS works as publisher: [onPathUpdate] newPath.availableInterfaces: ["nan0"]

审核回复：Issue Description The app uses public APIs in an unapproved manner, which does not comply with guideline 2.5.1. Specifically, the app still uses the ScreenTime API to hide apps. Since there is no accurate way of predicting how an API may be modified and what effects those modifications may have, unapproved uses of public APIs in apps is not allowed. 代码我都没有怎么改，然后之前2025年都上架成功了的，现在更新一个版本后，就不让上架了，是怎么回事？

The container appears to enter an unstable state. Inconsistent state after deletion Here's something that might help narrow this down. After one of the zone deletions, I deployed the same build to a second device signed into a different iCloud account that had previously accepted the CKShare. Without sending a new invite, that device found the "Household" zone via allRecordZones() on sharedCloudDatabase — it could pull all 578 records, push updates, and the share URL still resolved. Meanwhile, the owner device (zone creator) gets "zone not found" from both allRecordZones() and direct recordZone(for:) on privateCloudDatabase. So it looks like the zone is deleted from the owner's private database, but the CKShare and zone records remain accessible to participants via the shared database. Participants can still read and write as if nothing happened — the owner just can't see the zone anymore. This also creates a recovery problem — when the owner creates a new zone with the same name, it gets a new CKShare URL, but the participant is still connected to the old "ghost" zone. The two sides are permanently split. Does this mean the zone deletion is happening through a path that doesn't properly clean up the sharing infrastructure? Is this expected behavior when a zone-wide CKShare's zone is deleted, or does it suggest the deletion is happening through an abnormal server-side path? What I've ruled out Hypothesis Test Result publicPermission = .readWrite Changed to .none + explicit addParticipant Zone survived longer but still eventually deleted Zone name tombstoning Tested 6 fresh names never used in this container All eventually deleted Non-owner writes causing deletion Gated ALL non-owner push methods (recipe, meal plan, grocery, photo, event) Zone still deleted database.save(share) vs modifyRecords Switched to modifyRecords(saving:deleting:) Zone still deleted NSPersistentCloudKitContainer interference Removed all Core Data CloudKit code Zone still deleted Double share acceptance Fresh app install, single acceptance only Zone still deleted Advanced Data Protection Neither account has ADP enabled Not the cause Programmatic vs system acceptance Tested both container.accept() and tapping share link Zone still deleted CloudKit Dashboard No ZoneDelete operation is visible in the logs.

Hi everyone, I'm at the six-week mark of my Apple Developer Program enrollment and feeling pretty stuck. I wanted to post here to see if anyone else has been through something similar — and, hopefully, to get some guidance on what to do next. Six weeks since I submitted my enrollment application. Zero email updates from Apple at any point during this time — no acknowledgment, no status change, nothing. I called Apple Developer support about two weeks ago. The representative told me that additional documents had been requested and submitted on my behalf. That was promising — but since then, complete silence. I have heard nothing further in the two weeks since that call. I understand there can be legitimate delays, especially for organizations or businesses going through identity verification. But six weeks without any proactive communication feels excessive, and it's making it difficult to plan any development work or App Store submissions. Has anyone else experienced a timeline like this? Any insight from folks who've been through a lengthy enrollment would be really appreciated. At this point I'm not sure if I should keep waiting, call again, or try something else entirely. Thanks in advance.

When I use Xcode 26 (0.1, 1) for debugging and hit a breakpoint, using "step over" causes the debugger to freeze at a random line of code. Clicking "Pause program execution" indicates that the line is being executed, but the breakpoint never exits, seemingly causing a freeze. The application on the simulator also becomes unresponsive. However, when I do not use breakpoints, my program runs smoothly, and debugging on a physical device does not cause any freezes. This issue only occurs with the simulator. I am using Xcode on Apple Silicon, and due to some third-party SDKs that depend on Rosetta, our app can only run on the Rosetta simulator. We did not encounter this issue when using Xcode 16.x for simulator debugging. The current situation with Xcode 26.x significantly reduces our development efficiency. What could be causing this, and is there a solution?

I am requesting full deletion and termination of my apple developer account and all data and revocation of the Apple Developer Agreement. I am revoking Apple Developer Agreement. This should be irreversible. I have already tried to contact apple developer support few times and the request just gets ignored and closed. The developer account is associated with my Apple ID that I am on forums with. Thanks.

Hi all, I'm working on a cross-platform runtime that manages a pool of threads (think game engine / emulator style... dozens of guest threads mapped 1:1 to host pthreads). It was originally written for Linux and Windows and we're now porting to macOS on Apple Silicon. We've hit a wall with a deadlock on macOS and traced it back to our use of POSIX unnamed semaphores (sem_init / sem_wait / sem_post) for thread suspend and resume. We were unaware these have never actually been implemented on macOS, sem_init silently returns -1 with ENOSYS and then sem_wait just hangs forever. That explains our deadlock. The tricky part is how we use them. Our suspend mechanism works by sending SIGUSR1 to a target thread via pthread_kill. The signal handler then calls sem_wait to block the thread in place until another thread calls sem_post to resume it. So whatever we replace sem_init/sem_wait with needs to be safe to call from inside a signal handler. From what I can tell: dispatch_semaphore_wait is not documented as async-signal-safe pthread_cond_wait is also not async-signal-safe os_sync_wait_on_address looks promising but requires macOS 14.4+ which is a pretty high floor We could spin on a std::atomic with .wait() / .notify_all() but I've seen reports of high wake latency (up to 15ms) in libc++'s implementation on macOS My questions: What's the recommended way to block a thread inside a signal handler on macOS? Is there an async-signal-safe wait primitive I'm missing? Would restructuring to avoid blocking in the signal handler entirely be the better approach? For example, having the signal handler just set an atomic flag and then checking it at yield points — would that be the expected pattern on macOS? For the non-signal-handler suspend/resume paths, is dispatch_semaphore_t the right replacement for sem_t, or is there something better suited for high-frequency thread synchronization in 2026? Separately, we're also using ucontext (makecontext/swapcontext) for a fiber system on macOS and hitting issues on native arm64, it works under Rosetta but breaks natively. We have a setjmp/longjmp + manual stack pivot backend we can switch to. Is there any plan to fix or un-deprecate the ucontext functions on arm64, or should we just move off them permanently?

App ID: 6761302938 I've provided the DSA compliance, but it is stuck in the "In review" state.

Need to vent a bit before relaxing for Christmas... WatchOS IAP using Storekit 2 is such a mess...is nobody actually using this or does Apple just not care for the user experience here? Lots of users experience after the purchase confirmation double tap on the side button an instant return to the purchase screen with nothing actually happening. No error message whatsoever. There is just one remedy: users need to unpair and re-pair their watch, including restoring a backup and setting up their wallet again. Nobody really wants to do this, or doesn't believe me and think this is just typical support BS, because their watch is paired and most things just work as they expect. And it turns away a customer, often leaving a bad review. And I can't do anything about it. Other errors in the purchase process are reported, but like "process interrupted" in case the payment is not setup correctly (credit car no longer valid or sth.). How should the user know? There must be better ways of letting him know what exactly the problem is. You need to implement a "Restore Purchase" function, otherwise you're not passing the review. But it really asks every time for the AppStore password, and users with crazy passwords -- that they rightfully should have! -- have almost no chance of typing them successfully on the tiny AW keyboard. Why is it not also just a side button double tap like for purchase? At the very least you would need access to the keychain PWs or allow pasting of sth. copied on the paired iPhone. Promo Codes for IAP on AW-only apps just don't work. AW has no redemption at all, and on the iPhone the AppStore will try to talk to a companion app (which AW-only doesn't have) and the end up in a dead-end installation effort. This all feels like never really tested in the field, and people are of course blaming the 3rd party dev. for all these issues. And opening a ticket is just leading nowhere -- at best it's closed after months with the hint "duplicate" but w/o any chance for me to see that one that they then actually work on and track progress. It's all so frustratingly broken...

Hi all, I’m trying to determine whether the loudness gap I’m seeing between AlarmKit alert playback and normal app-managed playback is expected behavior, a sound-asset issue, or something that should be reported as a bug. Observed behavior When an alarm fires through AlarmKit while the device is locked, the alarm sound is significantly quieter than playback of the same or very similar audio once the app is active and using its own audio session. The difference is large enough that it does not feel like a small mastering difference. It feels like the AlarmKit / system alerting path is using a meaningfully lower effective output level than normal app playback. Test scenario My repro is roughly: Schedule an alarm with AlarmKit. Lock the device. Let the alarm fire and listen during the system alerting phase. Enter the app / continue into the app-driven alarm experience. Play the same or equivalent alarm asset via app-managed playback. Result: AlarmKit / lock-screen alerting phase sounds much quieter. In-app playback sounds noticeably louder and fuller on the same device. Current implementation Alarm flow is currently split into two paths: 1) System alarm path Alarm scheduling and alert surfacing via AlarmKit Device may be locked No attempt to manipulate system volume No private APIs 2) In-app playback path After app activation, playback uses: AVAudioSession category .playback AVAudioPlayer Audio is routed as normal app playback This path sounds substantially louder than the AlarmKit path Important detail I am not asking how to override system volume. I understand that AlarmKit appears to follow the system ringer / alert volume model and does not expose a public API for custom alarm loudness. My question is narrower: Is it expected that the same asset or an equivalent asset will sound materially quieter during the AlarmKit alerting phase than during ordinary app playback with AVAudioSession(category: .playback)? Questions Is the lower perceived loudness during AlarmKit alerting an expected property of the framework / system alarm path? Does AlarmKit playback use a different output path, gain policy, processing chain, or speaker treatment than normal app playback with .playback? Are there recommended authoring constraints for AlarmKit alarm sounds to maximize perceived loudness on iPhone speakers? transient-heavy mix stronger mids reduced low-end different LUFS / peak strategy shorter attack, etc. Has anyone measured this directly with: the same WAV / CAF file same device same system volume locked AlarmKit playback vs unlocked in-app playback If this is not expected, would Apple want this reported as a bug with: sample project exact iOS version device model screen recording / audio recording What I’m trying to figure out For alarm-app UX, this matters a lot because: AlarmKit is the most reliable lock-screen/system path. But if AlarmKit playback is substantially quieter than normal app playback, the alarm experience is inconsistent depending on device/app state. That makes it hard to know whether to treat this as: expected system behavior, a framework limitation, an asset/mastering problem, or a bug. If anyone has tested this in a controlled way or received guidance from Apple/DTS, I’d appreciate any technical detail. Thanks.

We're experiencing an issue where the CarPlay Simulator (from Apple Developer Additional Tools) stopped connecting to our iPhones as of March 4th, 2025. The simulator gets stuck indefinitely on "Connecting to phone" and never completes the pairing. Environment App: Oracle Field Service iOS app (with CarPlay support) Tool: CarPlay Simulator from Apple Developer Additional Tools (developer.apple.com/download/all/) Issue start date: Wednesday, March 4th, 2025 Tested on: Multiple Mac machines, multiple iPhones Multiple CarPlay Simulator versions tested What's happening The CarPlay Simulator launches but displays "Connecting to phone" indefinitely. It was working correctly prior to March 4th with no changes on our end. What still works CarPlay functions correctly when the same iPhone is connected to a real car, confirming the issue is specific to the simulator. Troubleshooting steps already attempted Reset permissions and re-added the simulator Forgot the simulator and re-paired it Changed the USB cable Tested on multiple Mac machines Tested on multiple iPhones Tried multiple versions of the CarPlay Simulator Confirmed no VPN is in use Confirmed with IT, no OS updates or enterprise restrictions were applied Questions Has anyone else experienced this since March 4th? Was there a change in CarPlay Simulator behavior or a requirement on the Apple side (certificate, entitlement, protocol) around that date? Is there a known workaround or fix?

Hello everyone, I am looking for some advice or shared experiences regarding a prolonged App Review Board appeal process. I submitted my app earlier this month. On March 3rd, it was rejected under guideline 4.3(b) Spam. On the exact same day (March 3rd), I submitted a detailed appeal to the App Review Board. In my appeal, I provided clear documentation and explanations to prove that the app is not a generic template. I specifically highlighted our proprietary algorithm that calculates a unique total daily energy percentage for users, which distinctly separates it from standard, saturated apps in the market. The issue: It has now been 23 days since I submitted the appeal, and I have not received any response from the Board. My main concern is the lack of visibility. Since appeals to the Board do not appear in the Resolution Center UI, I have no way of knowing if my ticket is actually actively open, in a queue, or if it has been lost due to a system glitch. I recently tried reaching out to general support to verify the ticket's status, but I only received an automated generic response stating that if I have already appealed, I should just wait. My questions for the community: Has anyone else experienced wait times exceeding 3 weeks for a 4.3(b) appeal recently? Is there any workaround to simply verify that an internal appeal ticket is genuinely open and hasn't fallen through the cracks? Any insights or advice on how to proceed would be greatly appreciated. Thank you!
