Not working on IOS

[computerfriendlog2]

My Code
void _tagRead() async {
print('testing -------------> read tag');
isWritingNFC=true;
setState((){});

bool isAvailable = await NfcManager.instance.isAvailable();

print('nfc  is    available ...... ${isAvailable}');

//try{
  NfcManager.instance.startSession(
      onDiscovered: (NfcTag tag) async {
    print('nfc  here1...... $tag');
    print('nfc  here2...... ${tag.data}');
    print('nfc  here3...... ${tag.data['id']}');
    print('nfc  here4...... ${tag.handle}');
    String? hexId;
    try {
      // Attempt to retrieve the ID from various potential sources
      if (tag.data.containsKey('nfca')) {
        final id = tag.data['nfca']['identifier'];
        hexId = _convertIdToHex(id);
      } else if (tag.data.containsKey('nfcb')) {
        final id = tag.data['nfcb']['identifier'];
        hexId = _convertIdToHex(id);
      } else if (tag.data.containsKey('iso7816')) {
        final id = tag.data['iso7816']['identifier'];
        hexId = _convertIdToHex(id);
      } else if (tag.data.containsKey('iso15693')) {
        final id = tag.data['iso15693']['identifier'];
        hexId = _convertIdToHex(id);
      } else if (tag.data.containsKey('ndef')) {
        final id = tag.data['ndef']['identifier'];
        hexId = _convertIdToHex(id);
      }

      // Display the ID or a message if ID is null
      setState(() {
        print('NFC card id is here----> ${hexId!.replaceAll(':', '')}');
      });
    } catch (e) {
      print('NFC card id getting error here----> ${e.toString()}');
    }

    /// ////////////////////////////////////////////
    Ndef? ndef = Ndef.from(tag);
    print('nfc tag is here...... ${ndef!.cachedMessage!.records.first.payload}');
    String readTag = utf8.decode(ndef.cachedMessage!.records.first.payload);
    //String serialKey='';
    print('Decoded content: $readTag');
    if(readTag.contains('---') && readTag.contains('...') ) {

      // if(readTag.contains('+++') ) {
      //   print('serialKey content: ${readTag.split('...')[1]}   ===> ${readTag.split('...')[1].split('+++').first}');
      //   serialKey=readTag.split('...')[1].split('+++').first;
      //   print('Decoded serialKey :${serialKey} ');
      // }
      readTag= readTag.split('---')[1].split('...').first;
    }
    Helper.msgDialog(context, "NFC TAG is '$readTag'.", () {// and serial key is $serialKey
      Navigator.of(context).pop();
    },   );
    print('nfc tag is here...... ${ndef.maxSize}');
    isWritingNFC=false;
    setState((){});
  },
    onError: (d) async {
        print('nfc error is 1 here-----> ${d.type.toString()}');
        print('nfc error is 2 here-----> ${d.type.name}');
        print('nfc error is 3 here-----> ${d.details.toString()}');
        print('nfc error is 4 here-----> ${d.message}');
        print('nfc error is 4 here-----> ${d.toString()}');
      //return Future.value();
    },
    alertMessage: 'test alert'
  );
// } catch(e) {
//   print('testing -------------> ${e.toString()}');
//   Helper.toast('Please try again');
//   isWritingNFC=false;
//   setState((){});
// }

}

I used other dependency its working means there is no any configuration issue.

But in this case its not working on IOS, either android is working fine.

I'm getting output
flutter: nfc is available ...... true
flutter: nfc error is 1 here-----> NfcErrorType.unknown
flutter: nfc error is 2 here-----> unknown
flutter: nfc error is 3 here-----> null
flutter: nfc error is 4 here-----> Missing required entitlement
flutter: nfc error is 4 here-----> Instance of 'NfcError'
