ISHPullUp from iosphere provides a split view controller inspired by the iOS 10 map app with a bottom view that you can drag in and out of view with a pull gesture.
ISHPullUP provides notifications for its various states, up, down, and neutral and you can customize the view changing the size when dragged out, the colors, and more.
Here are a couple of images from the readme showing ISHPullUp in action:

A nice pull up view component.
