I have an iPhone 8 running iOS 12.2 and iPhone 8 Max running iOS 12 and in both cases, calling the method NFCReaderSession.readingAvailable results in a crash with the following message [NFCReaderSession readingAvailable]: unrecognized selector sent to class. This method is supposed to be available in iOS 11. I have tested this on my iPhone 6s running iOS 12.4 and the method returns false, as it should because NFC isn’t supported on an iPhone 6s. I have tested on my iPhone Xs and the method returns true, as it should. I’m trying to narrow down if this is bug with a specific phone version with iOS 8 and iOS 12? Thanks for any help!
