I used ionic geofence native plugin for Geofence and it is successfully working in Android, but it is not working for iOS. Kindly refer my below code. I can see in Xcode log geofence added successfully and monitoring location but not showing any notification.

let fence = {  
id: ‘69ca1b88-6fbe-4e80-a4d4-ff4d3748acdb’, //any unique ID  
latitude: Number(this.cLatitude), //center of geofence radius  
longitude: Number(this.cLongitude),  
radius: this.radius, //radius to edge of geofence in meters  
transitionType: 1 , //see ‘Transition Types’ below  
notification: { //notification settings  
id: 1, //any unique ID  
title: ‘You have crossed a fence.’, //notification title  
text: ‘You just left the site.’, //notification body  
openAppOnClick: true //open app when notification is tapped  
}  
}

```
  this.geofence.addOrUpdate(fence).then(
    () => console.log('Geofence added ios and android'),
    (err) => console.log('Geofence failed to add')
  );

  this.geofence.onTransitionReceived().subscribe(resp => {
    console.log("resp :", resp);
    //alert("You just crossed the fence");
  });
```

Think the Ionic team could start prioritizing helping the community a little bit more… It’s frustrating how absent they are.

I have removed that and create fence using geolocation

Would ut be possible for you to svare the code? Ut would be to so much help.

I just used the this link for location update

Also for fence please use this method.

getDistanceFromLatLonInm(lat1,lon1,lat2,lon2) {  
var R = 6371; // Radius of the earth in km  
var dLat = this.deg2rad(lat2-lat1); // deg2rad below  
var dLon = this.deg2rad(lon2-lon1);  
var a =  
Math.sin(dLat/2) \* Math.sin(dLat/2) +  
Math.cos(this.deg2rad(lat1)) \* Math.cos(this.deg2rad(lat2)) \*  
Math.sin(dLon/2) \* Math.sin(dLon/2)  
;  
var c = 2 \* Math.atan2(Math.sqrt(a), Math.sqrt(1-a));  
var d = R \* c; // Distance in km  
var m = d\*1000;  
return m;  
}

deg2rad(deg) {  
return deg \* (Math.PI/180)  
}

This doesnt really tell me much about the geofence… This just calculates the distance, right?
