corelocation API giving panic about macdriver

[progrium]

Why are you calling LocationManagerDidUpdateLocations on your delegate?

[tejaskumark]

@progrium Thanks for the reply.

If I don't call that method then it panics with different signature mentioning LocationManagerDidUpdateLocations must have to be called.

[progrium]

You wanna share that?

[tejaskumark]

Sorry, I should have shared that earlier. Here are the traces

[progrium]

But it's saying you need to implement it. locationdelegate.SetLocationManagerDidUpdateLocations(...)

[tejaskumark]

Thanks a lot, was able to make it work.
