ERROR: Method 'registerTag:' not defined in Plugin 'NfcPlugin'

I've been trying to get this working on iOS with no luck. I call the beginSession() function before attempting to start the scan.

The console throws out the following error:

ERROR: Method 'registerTag:' not defined in Plugin 'NfcPlugin'

Here is a sample of the code:

if (this.currentPlatform === 'ios') {
            await this.nfc.beginSession().toPromise();
            this.scanner$ = this.nfc.addNdefListener(() => {
                this.status = 'Scanner Ready...';
            }, () => {
                this.status = 'Failed to initialize scanner.';
            }).subscribe((e) => {
                this.tagDiscovered(e);
            })
        } else {
            this.scanner$ = this.nfc.addTagDiscoveredListener(() => {
                this.status = 'Scanner Ready...';
            }, () => {
                this.status = 'Failed to initialize scanner.';
            }).subscribe((e) => {
                this.tagDiscovered(e);
            });
        }

Any help would be greatly appreciated!

I also receive this error when using addTagDiscoveredListener for iOS. From the CoreNFC documentation provided by apple:

NFCTagReaderSession A reader session for detecting ISO7816, ISO15693, FeliCa, and MIFARE tags.

and

NFCVASReaderSession A reader session for processing Value Added Service (VAS) tags.

are still in Beta and will be available within iOS 13. So the solution is wait for iOS 13 release and then some good soul to add support for addTagDiscoveredListener for iOS.

EDIT:

Otherwise if you want to listen only NDEF tags to iOS I do use the following code with @ionic-native/nfc and it works perfectly.

import { NFC } from '@ionic-native/nfc';
...
constructor(private nfc: NFC) {...}
...
enableNFC(): void {
 this.nfc.enabled().then(() => {
      this.subscribers.nfcSession = this.nfc.beginSession().subscribe(() => {
        this.subscribers.addListener = this.nfc.addTagDiscoveredListener(() => {}).subscribe((event: any) => {
          alert(this.nfc.bytesToString(event.tag.ndefMessage[0].payload))

          this.subscribers.nfcSession.unsubscribe();
          this.subscribers.addListener.unsubscribe();
        });
      });
    }, () => {
      alert('NFC NOT ALLOWED');
    });
}

iOS works in v1.1.0. addTagDiscoveredListener is not supported on iOS.
