"enterregions" event does not work for Geofence module. - http://docs.appcelerator.com/platform/latest/#!/api/Modules.Geofence Just include the module to the project then run the following code to the device - https://platform.appcelerator.com/#/download Test code

var window = Titanium.UI.createWindow({
	backgroundColor : 'red'
});

var titleInWinA = Ti.UI.createLabel({
	text : 'Location',
	left : 70,
	top : 100,
	width : Ti.UI.SIZE,
	height : Ti.UI.SIZE,
});
window.add(titleInWinA);

var lat;
var lon;

if (Ti.Geolocation.locationServicesEnabled) {
	Titanium.Geolocation.purpose = 'Get Current Location';
	Titanium.Geolocation.getCurrentPosition(function(e) {
		if (e.error) {
			alert('Error: ' + e.error);
		} else {
			Ti.API.info(e.coords.latitude + '\n' + e.coords.longitude);
			titleInWinA.setText(e.coords.latitude + '\n' + e.coords.longitude);
			lat = e.coords.latitude;
			lon = e.coords.longitude;
			Enterregions();
		}
	});
} else {
	alert('Please enable location services');
}

function Enterregions() {

	var Geofence = require("ti.geofence");

	var newRegion = Geofence.createRegion({
		center : {
			latitude : lat,
			longitude : lon
		},
		radius : 500,
		identifier : 'Appcelerator'
	});

	Geofence.startMonitoringForRegions([newRegion]);

	Geofence.addEventListener("enterregions", function(e) {
		Ti.API.log('####### enterregion #######: ' + JSON.stringify(e));
		alert('enter region fired');
	});


	Geofence.addEventListener("monitorregions", function(e) {
		Ti.API.log('####### monitorregions #######: ' + JSON.stringify(e));

	}); 


}

window.open();

<key>NSLocationAlwaysUsageDescription</key>
                <string>Specify the reason for accessing the user's location information.
					This appears in the alert dialog when asking the user for permission to
					access their location.</string>

Thanks

Before I start further investigations, please validate the issue with this (corrected) demo-code, yours does not look valid for newer iOS-versions:

   var Geofence = require("ti.geofence");
   var window = Ti.UI.createWindow({
       backgroundColor: 'white'
   });
   
   var titleInWinA = Ti.UI.createLabel({
       text: 'Receiving location ... ',
       left: 70,
       top: 100,
   });
   window.add(titleInWinA);
   
   window.addEventListener("open", function() {
       checkLocationPermissions();
   });
   
   function checkLocationPermissions() {
       if (!Ti.Geolocation.hasLocationPermissions()) {
           Ti.Geolocation.requestLocationPermissions(Ti.Geolocation.AUTHORIZATION_ALWAYS, function(e) {
               if (!e.success) {
                   Ti.API.error("Error requesting location permissions: " + e.error);
                   return;
               }
   
               getCurrentPosition();
           });
       } else {
           getCurrentPosition();
       }
   }
   
   function getCurrentPosition() {
       Ti.Geolocation.getCurrentPosition(function(e) {
           if (e.error) {
               alert('Error: ' + e.error);
           } else {
               Enterregions(e.coords.latitude, e.coords.longitude);
           }
       });
   }
   
   function Enterregions(latitude, longitude) {
   
       Ti.API.info(latitude + '\n' + longitude);
       titleInWinA.setText(latitude + '\n' + longitude);
   
       var newRegion = Geofence.createRegion({
           center: {
               latitude: latitude,
               longitude: longitude
           },
           radius: 500,
           identifier: 'Appcelerator'
       });
   
       Geofence.startMonitoringForRegions([newRegion]);
   
       Geofence.addEventListener("enterregions", function(e) {
           Ti.API.info('####### enterregion #######: ' + JSON.stringify(e));
           alert('enter region fired');
       });
   
       Geofence.addEventListener("monitorregions", function(e) {
           Ti.API.info('####### monitorregions #######: ' + JSON.stringify(e));
       });
   }
   
   window.open();

Most important: - Validate the permissions status - Don't store global variables for this - Don't require a module inside an event-listener - Use Ti.API.info instead of Ti.API.log ("log" might not be displayed in the default log-level) Also ensure to test on a device, thanks!
