Your question is Parsing Geo JSON to Map. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about how you would parse a local JSON file containing geo points and display them on a Bolt iOS MapKit map, with clear architecture, testability, and robust error handling that supports migrating to a remote data source later.
