We have tried with apple map but apple map SDK does not allow us to draw polyline over the map so we have seen one application that is doing a similar thing using MapBox SDK. But unfortunately, Mapbox official documentation does not provide any guides about implementing Mapbox SDK in Apple WatchOs.

We have also tried to contact Mapbox support but we didn't get a response from there so if anyone knows how to integrate Mapbox SDK in Apple watchOS.
