On iOS 15 beta 4, NFC scan success sheet is displayed when NFC scan time out. (At this time, tagReaderSession(_:didInvalidateWithError:) is called normary.) It worked fine (NFC scan success sheet is not displayed) on iOS 15 beta and iOS 14.

The following phenomenon is occurring on iOS15 beta 4. (I didn't check in other iOS 15 beta versions.) Immediately after completing the NFC scan, when the App ran nfcReaderSession?.begin(), tagReaderSession(:didInvalidateWithError:) was called and the error code was 200. Immediately after that, tagReaderSessionDidBecomeActive(:) was called and the scan sheet was displayed. The [Cancel] button in the scan sheet is not operated. If you execute the method after a while after the NFC scan is completed, the above phenomenon will not occur.

On iOS 15 beta 2 and beta 3, NfcReaderSession.invalidate(errorMessage: ) dose not work, and NfcReaderSession.invalidate() is displayed. (The NfcReaderSession.invalidate() for error message dose not work.) It worked fine on iOS 15 beta. This is a beta 2 and beta 3 issue and will it be resolved in the next version?

On iOS 15 beta 2, NfcReaderSession.invalidate(errorMessage: ) dose not work, and NfcReaderSession.invalidate() is displayed. (The NfcReaderSession.invalidate() for error message dose not work.) It worked fine on iOS 15 beta. This is a beta 2 issue and will it be resolved in the next version?
