Geofencing on managed workflow iOS

Please provide the following:

  1. SDK Version: 37
  2. Platforms(Android/iOS/web/all): iOS
  3. Expo Client Version: 2.15.5
  4. Device: iPhone 11 Pro (iOS 13.4.1)

Hi!

I’m in the process of building a small app that will utilize Geofencing feature and encountered with an error when calling Location.startGeofencingAsync (stacktrace at the end of this post)

After googling little bit, this looked like a permission related issue in latest iOS. app.json’s ios field looks like this.

...,
"ios": {
  ...,
  "infoPlist": {
        "UIBackgroundModes": ["location", "fetch"],
        "NSLocationWhenInUseUsageDescription": "Allow HereHere to use your location",
        "NSLocationAlwaysUsageDescription": "Allow HereHere to use your location in the background for GeoFencing",
        "NSLocationAlwaysAndWhenInUseUsageDescription": "Allow HereHere to use your location in the background for GeoFencing"
      }
  }

So I built a standalone app and tested in iOS simulator, and it seems to be working! I’m wondering if there’s a way to get this working in development flow and would appreciate any pointer!

Thanks! And here’s minimal(?)-ish code that I was able to reproduce the issue. GitHub - arthurpark/ExpoGeofence: Geofence test with Expo
