Core NFC Enhancements - Error attempting to read tag

Further notes on this issue:

Here's a capture of the session with the phone & smartcard (bottom of message):

*Note towards the end the iPhone send a select command for AID A00000014100, which is the AID I have declared in my Info.plist and does exist on the card. The card, in turn, responds back with 90 31 32 33 SW1=90 SW2=00, which is the correct hello from the application. It appears that the moment that this happens, nfcd crashes. The phone I'm testing on is an iPhone 8.

I tried to start iso14443 session, but I got same error "Session invalidated unexpectedly" on iPhoneX iOS13.

Exceptionally, ePassport detection succeeded(called tagReaderSession(_ session: NFCTagReaderSession, didDetect tags: [NFCTag])),

but failed with other generic smartcards in spite of the appropriate AID is set in Info.plist.

With "Additional Logging" setting enabled, I can see that nfcd was crashing.

It seems a issue of nfcd so we need support.

Thanks.

I seem to be seeing the same behaviour. I have both an ePassport and generic transport AID configured in Info.plist. I can successfully detect an ePassport, but the transport card results in nfcd crashing.

I also start iso14443 session and getting a crash of com.apple.nfcd on iPhone 7.

Confirming that iOS 13 beta 2 also resolved this for me 🙂

My Question: How did you do that? I am striggeling to connect at all. On Android I can connect to the passwort and it shows up as an iso14443-4 tag. So I expecting this should work on iOS as well.

Hi @StuartyBoarder, Can you please let me know about how your ePassport connected with iso14443-4 tag.
