we are unable to install pod for mapbox navigation. Please help me
we are follow the mapbox navigation documentation step by step . We are successfully install the pod 'MapboxNavigation' When i am using swift language with Xcode 9.2
But when we go through language ObjectiveC with same Xcode9.2 version, we are unable to install the pod.. the issues are given in the screen shoot.
Refer to the Github project, MapBox supports Xcode 9 and swift 4, maybe the website documentation is outdated.
Thanks to Mapbox i got it solution , we can go through the Carthage ,we have no problem with objective c in xcode 9 . Thanks.
