"This method can cause UI unresponsiveness if invoked on the main thread."

Minor runtime issue:

LocationProvider.swift:55 This method can cause UI unresponsiveness if invoked on the main thread. Instead, consider waiting for the '-locationManagerDidChangeAuthorization:' callback and checking 'authorizationStatus' first.

The highlighted line is the return CLLocationManager.locationServicesEnabled() in LocationProvider.swift, here:

    public var isAvailable: Bool {
        #if SKIP
        return locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER) || locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)
        #else
        return CLLocationManager.locationServicesEnabled()
        #endif
    }

I'm getting the same purple warning as well. /// Returns true if the location is available on this device
public var isAvailable: Bool {
#if SKIP
return locationManager.isProviderEnabled(LocationManager.FUSED_PROVIDER) || locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER) || locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)
#else
return CLLocationManager.locationServicesEnabled()
#endif
}
