TechCrunch:

Apple is finally adding transit options to its Maps app for the city of Paris. Starting today, you can use Apple Maps to calculate itineraries using public transportation.

You’ll find subway, RER and bus lines, and even Transilien lines. Just like in Google Maps, you can look around the map with a new subway layer or you can calculate an itinerary from A to B. If you tap on a station, you can see all the lines leaving this station as well as real time information about the next departures.

Finally, you’ll also find Autolib car sharing stations as well as Vélib bike sharing stations. Unfortunately, it doesn’t say if there are bikes or spaces available.

Surprised that this took so long, but glad the data is finally available.
