Description Adam Hartley [MSFT] 2015-07-29 05:04:56 UTC
Created attachment 12264 [details]

## Overview

When monitoring a region for geofencing with CLLocationManager, RegionEntered is not called when entering the region and RegionLeft is not called when leaving the region.

## Steps to reproduce

1. Run attached sample (GeofencingXam) in the simulator
2. Tap the button to start monitoring
3. Change the location to "Apple" or Lat: 37.29430502 Lon: -122.09423697
4. Change the location to anything away from the previous location

## Expected result

A message should be written to the console to say that the region has been entered, then another for exiting.

## Actual result

No message as the methods are never called

## Notes 

Included in the zip is GeofencingObjC which is an Objective-C sample along the same lines as the Xamarin sample.

If you run the app, do the location changes in steps 3 and 4 above, you will see the label being updated accordingly.

I do not get the ObjC app to work (label says "Label") on the simulator (Xcode 6.4 / iOS 8.4) even when changing the location.

Please include all version information (from XS about box)

I have just tested the obj-c sample and it does work for me. I have noticed that it appears to take a while to realise it has entered the region. Xcode 6.4 and iOS 8.4.

Changing status back to NEW, as it looks like Adam supplied the requested information.

This works fine for me: https://www.dropbox.com/s/4n3qg3dmnyka2n1/bug32557.mov?dl=0

There is a quirk with the simulator though: clicking in the menu Debug -> Location -> Apple does not give any notification (neither if it should be leaving the region, nor entering).

So every time I want to enter the Apple location, I click first Apple, then Custom Location (which will now have the coordinates for the Apple location). Apparently selecting the coordinates for the Apple location as a custom location works just fine.
