A reader session for detecting NFC Data Exchange Format (NDEF) tags.


class NFCNDEFReaderSession : NFCReaderSession


As with the NFCReaderSession base class, only one NFC NDEF reader session can be active in the system at a time. If you create an additional session, the system puts it in a queue and processes it in first-in, first-out (FIFO) order.


Creating a Session

protocol NFCNDEFReaderSessionDelegate

A protocol that an object implements to serve as an NDEF reader session delegate.

Connecting to a Tag

func connect(to: NFCNDEFTag, completionHandler: (Error?) -> Void)

Connects the reader session to a tag and activates that tag.

Restarting the Polling Sequence

func restartPolling()

Restarts the polling sequence so the reader session can discover new tags.
