iOS 12 includes a revamped and rebuilt Maps app that uses a new Apple-designed Maps engine that will display foliage, pools, buildings, pedestrian pathways, and other map elements more accurately. The new Maps also includes significant improvements to traffic, real-time road conditions, construction, and more, plus it will enable Apple to push out changes and fixes more quickly.
The revamped Maps app is available in the Northern California area during beta testing. After iOS 12 launches, Apple will continue rolling out the new maps to additional U.S. locations across late 2018 and 2019.
