This should be in the current release, right?

Can someone help me by telling me why this delegate method can't be found in my project, not even when using the latest cocoa pod symbols from master.

# Podfile
pod "Mapbox-iOS-SDK", git: "git@github.com:mapbox/mapbox-gl-native.git"

# Podfile.lock
...
CHECKOUT OPTIONS:
  Mapbox-iOS-SDK:

    :git: git@github.com:mapbox/mapbox-gl-native.git
...

It looks like the Mapbox SDK headers didn't update in my project. Not even after reinstalling Mapbox.

Ok, forget what I said. Just built from source, everything works.

Uninstallation from my Xcode project had failed apparently. Completely removed Mapbox pod and my project was still building normally, even after a Product -> Clean. Cleaning Xcode cache folders did the the trick.

The latest pod release and building from source both work now. Thanks!
