Social networking service Foursquare is now an official supplier of business listings for Apple Maps, joining Yelp in giving users ratings and reviews for local businesses.
Originally popular as a check-in service, Foursquare now revolves around discovering and rating local businesses and attractions. The company is in fact a direct competitor to Yelp, which also supplies listings for Maps.
Talk about a deal between Apple and Foursquare dates back to late 2012. It's not clear why an arrangement would take nearly three years to complete, though Foursquare's overhaul in 2014 — pushing check-in functions into a separate app, Swarm — likely added to the complexity.
Even with the improvements to Maps in iOS 9 and OS X El Capitan, Apple is known to be working on collecting still more data for the service. Vehicles are touring cities worldwide to gather street-level reconnaissance, presumably with something akin to Google Street View in mind.
In the long run though the company may use some of its data to help build a self-driving car.
