I created a demo to test core NFC and failed to write the iso15693 tag.

Code Block Byte bytes[8]={0x12,0x21,0x04,0x74,0x65,0x73,0x74,0x00};  
NSData *data = [[NSData alloc] initWithBytes:bytes length:8]; 
[iso15693Tag writeSingleBlockWithRequestFlags:RequestFlagSelect blockNumber:0x04 dataBlock:data completionHandler:^(NSError * _Nullable error) { 
   if (error) {  
     NSLog(@"Failed to write tag!");
    } else {
     NSLog(@"write succeeded!");
     }
   }];

I couldn't execute successfully and got the error message：
Error Domain=NFCError Code=100 "Tag connection lost" UserInfo={NSLocalizedDescription=Tag connection lost}

I would like to ask if core NFC supports writing iso15693tag？

I think I need a successful example of how to create a correct blockdata. I hope someone can help me. Thank you very much！
