Fixing Geo Location Permissions in iOS8

In iOS8, Apple has changed how geo location permissions work. This gist outlines an approach to fix this so Geo will continue to work in iOS8.

Before getting started with the code change, we need to update the tiapp.xml with a few keys.

If you wish to have Geo always run, you need to add the below key. The key NSLocationAlwaysUsageDescription is used when requesting permission to use location services whenever the app is running. To enable this, add the below to the tiapp.xml:

NSLocationAlwaysUsageDescription Reason that appears in the authorization prompt

// Requirements: a NSLocationWhenInUseUsageDescription entry in Info.plist
// Usage:  @State var locator = CLLocationManager.publishLocation()
//           and
//         .onReceive(locator) { location in
// Improvements needed: Move requestWhenInUseAuthorization into its own publisher and perhaps have a combineLatest pipeline for both authorized and valid location.
//                      A configuration param to init(), e.g. so each manager can have the same distanceFilter.
