gymkit in WatchOS 4.2 Beta 2 ?
Is gymkit supported in WatchOS 4.2 beta 2 ?It would seen it is supported into WatchOS 4.1 GM, but as I have installed the WatchOS 4.2 beta 2, I'm not able to downgrade to GM version :-(I would like to test the detectGym Equipement option for workout. With WatchOS 4.2 beta 2, I don't see any impact with this option : no NFC activities...Help is welcome.thx and br,Vincent

Write to xNT NFC
I know that as for now it’s only possible to read nfc tags. But for me and others that have a xNT chip inplant really need the possibility to write to NFC. Here in Sweden you can order train tickets and save them to NFC and then be read by the train conductors. So please Apple be brave and let us developers use the full potentials of iOS

Limit iPhone app to devices with Taptic Engine
I am working on an app in which a primary user interaction involves the use of taps from the Taptic Engine. Everything is working well, but I know this app will not have a good user experience on iPhones older than the iPhone 7.The only hardware capabilty that could limit devices is NFC (according to tables here: https://developer.apple.com/library/content/documentation/DeviceInformation/Reference/iOSDeviceCompatibility/DeviceCompatibilityMatrix/DeviceCompatibilityMatrix.html), but my app of course doesn't use NFC, and from what I can tell, the API for that is only open to special third parties. I could spend time to work on a worse version of the app that would function on older devices, but the result would be that most users would have a sub-par experience, resulting in poor ratings, etc.Can I artificially limit app availability with the NFC capability? Is there another way to do this?

Reply to CoreNFC SIGABRT
I found the reason of SIGABRT, you need to add Privacy — NFC Scan Usage Description key to info.plist in other case it will cause __CRASHING_DUE_TO_PRIVACY_VIOLATION__ error and SIGABRT signal

Please help- NFC App/QR Reader Approval
Please help. We created a QR and NFC reader which will allow users to scan QR codes or Tap NFC tags and launch the appropriate experience. They keep telling us our app appears to be marketing our services. Makes no sense as this is a simple QR reader and NFC reader. Anyone have suggestions how to describe? We have seen a few others get approved with the similar utility. This can read any QR code and any NFC tag.
