NFC Kaput
I keep seeing this in the Xcode when I launch my app: -[NFCTagReaderSession beginSessionWithConfig:]:468 error:Error Domain=NFCError Code=203 "System resource unavailable" UserInfo={NSLocalizedDescription=System resource unavailable}, errorCode: 0xcb Initially, the device was working with NFC. Now on multiple complete restarts of my app, the System resource is still not available. If I lock the screen and reenter iOS again, the problem persists. Rebooting the device appears to get it working again. I suspect this is only happening on iPhone 15 and iOS 18.01. My other devices I have do not exhibit the problem. I'd wager some service in the OS has crashed? There also appears to be limitation on renewing nfc sessions. Similar problems on iPhone 16 to what I experienced on iPhone 15. I don't know what they did with iPhone 15 and 16 but the NFC has really deteriorated for longer sessions. Seems the newer Apple HW is worse at NFC than my iPhone 11. Just providing feedback. The device also has 100% charge. Issues seem more prevalent with lower battery charge but that is not the case here.

EAAccessoryManager crashes
Hi, The company produces MFI-certified devices. A lot of users are affected. it happens when users are in the background. The crash happens in NSArray; it looks like the array is out of bounds to which EAAccessoryManager tries to access. The only assumption I have is that something is wrong with Threads. Maybe we are blocking a Thread somewhere, or EAAccessory should always work on the Main Thread but we switch streams to another thread. It is hard to believe that Apple could have such a simple bug. If it were Apple's bug, other companies who produce MFI devices could also experience the identical bug, but I don't see anyone raising the identical issue. The issues don't have a relation to iOS versions; it happens for us from iOS 13 till iOS 18. Thanks in advance, Eugene.

Companion app can't be installed on iPhone for some users who have installed the watchOS only version app
Hello! I'm facing the following Appstore issue. There was an watchOS only app, without a companion app. In current 1.6 version the app has a companion app and it can be properly installed by new users from their iPhones or watches. Unfortunately, all old users, who have installed the app from their watches don't see a way to install the app from the Appstore (they can download the latest watchOS version though). Many things have been tried - uninstalling, installing on the watch. Looking for a purchase, removing subscription, but without luck. The Appstore shows "purchased" button instead "Get" or the cloud icon. Is this a bug in the Appstore or there is a way to recover from this edge case. Thanks, Emil

CarPlay Development Resources for Head Unit
There are CarPlay resources from Apple (https://developer.apple.com/documentation/carplay/) but it seems entirely geared towards iOS app development. Are there any resources or documentation that help with CarPlay integration on the vehicle/head unit side of things? I believe you need to download the CarPlay Communication Plug-In and integrate that with the head unit platform and applications, but there isn't much documentation that comes along with the Plug-In .zip download. Is there a different place where resources for head unit developers is located?

Unexpected behavior when iPad is unlock and the application goes to Foreground. something happens and the application goes to background and foreground in a small period of time.
I have the our device connected , with Assistive Touch enabled and the application running in the foreground. At this point, I place the screen on standby and leave the device unattended for 10 minutes. After this period, I return, unlock the screen, and observe that our app is still running, and the connection with the device is re-initiated. However, something occurs at this stage that causes the application to briefly switch to the background and then immediately return to the foreground. This behavior leads to system instability. Ideally, once the application is running in the foreground, it should not transition to the background automatically. However, it seems to be doing so for a short duration—momentarily switching from the foreground to the background, then back to the foreground—which is causing the observed instability. OK, the iPad screen is unlocked AND App Appears. 2024-10-01 13:15:55 LOG: APP > Scene did become active 2024-10-01 13:15:55 LOG: APP > Init device Suddenly the application goes to background by itself?!?!?! 2024-10-01 13:15:55 LOG: APP > Scene will change from Foreground to Background 2024-10-01 13:15:55 LOG: APP > Scene changed to Background 2024-10-01 13:15:56 LOG: APP > Scene Will Enter to Foreground 2024-10-01 13:15:56 LOG: APP > Nib Name previous load : Home Other example OK, the iPad screen is unlocked AND App Appears. 2024-10-01 11:23:55 LOG: APP > Scene Will Enter to Foreground 2024-10-01 11:23:56 LOG: APP > Scene did become active 2024-10-01 11:23:56 LOG: APP > Init connection Suddenly the application goes to background by itself?!?!?! 2024-10-01 11:23:56 LOG: APP > Scene will change from Foreground to Background 2024-10-01 11:23:56 LOG: APP > Scene changed to Background 2024-10-01 11:23:56 LOG: APP > Scene Will Enter to Foreground 2024-10-01 11:23:56 LOG: APP > Scene did become active 2024-10-01 11:23:56 LOG: APP > Scene will change from Foreground to Background 2024-10-01 11:23:56 LOG: APP > Scene changed to Background 2024-10-01 11:23:56 LOG: APP > Scene Will Enter to Foreground 2024-10-01 11:23:56 LOG: APP > Nib Name previous load : Home FA FB15345245 this is happening under iPadOS18.1 beta5 and iPad12.9" 6th gen.

NFC Scanning Issue on iPhone 11 After Updating to iOS 18
I am experiencing an issue with NFC scanning on my iPhone 11 after updating to iOS 18. Previously, I was able to use NFC tags without any problems. However, since the update, the NFC functionality no longer works as expected. Installed OS: iOS 18.0 (22A3354) Here are the troubleshooting steps I have already tried: Opened the Shortcuts app. Tapped on Automation. Searched for NFC. Selected Run after confirmation. Tapped NFC Tag -> Scan. Unfortunately, nothing happens at this point; the NFC scan doesn't initiate. This issue has made it difficult for me to use NFC-dependent automations and functionalities that worked seamlessly before the update. Could you please provide guidance on how to resolve this problem? Thank you for your attention and support.
