A custom reusable slider control with 2 thumbs (range slider). Values range is between minimumValue and maximumValue (from 0 to 1 by default). The left thumb isn't able to go on the right side of the right thumb, and vice versa. Control enables multitouch (to use 2 fingers at 2 thumbs at the same time).

Please check Demo project for a basic example on how to use MARKRangeSlider.
