Note that a SELECT command with a P1 value of 0x04 (selection by DF name) will be checked against the values listed in the "com.apple.developer.nfc.readersession.iso7816.select-identifiers" in the Info.plist. Selecting an application outside of the permissible list will result in a `NFCReaderErrorSecurityViolation` error. - Parameters: - apdu: The command APDU object. - resultHandler: Completion handler called when the operation is completed. A `NFCErrorDomain` error is returned when there is a communication issue with the tag. `payload` may be nil. Command processing status bytes (SW1-SW2) are always valid.
