[iOS] watch return 'null'

[EnricoGiordano1992]

I wrote this code in Ionic 2 project:

    var zeroconf = (<any>window).cordova.plugins.zeroconf;
    zeroconf.registerAddressFamily = 'ipv4'; // or 'ipv6' ('any' by default)
    zeroconf.watchAddressFamily = 'ipv4'; // or 'ipv6' ('any' by default)
    zeroconf.watch('_myservice._tcp', '.local.',
      function(result:any) {
        console.log("dev:" + JSON.stringify(result));
      },
      function(err:any){
          console.log("err: "+err)
        }
      );

This code works on Android (tested), but in iOS doesn't work (it doesn't find my device). In particular, in iOS returns "null" in failure callback. I'm using Xcode 8.3.3 and Swift 3. How can I resolve this? What version of Xcode did you use?

Many thanks!

Latest version. Do you see any error message in the xcode console? You can enable some debugging with other swift flags: -D DEBUG

I've this error:

ZeroConf: watch _myservice._tcp.local.
ZeroConf: netServiceBrowser:didNotSearch:(Function) ["NSNetServicesErrorCode": -72004, "NSNetServicesErrorDomain": 10]

it's about the dots I think. must rather be: zeroconf.watch('_myservice._tcp.', 'local.',
