It should look like UISlider and have two thumbs.
- NMRangeSlider Looks good, many users, but the creator is gone and there's tons of personal forks. Doesn't work with Swift!
- TTRangeSlider Maintained, but doesn't look like UISlider. (It has neither thumbs nor a different bar colour for the selected range) It doesn't track touch very well, when touch leaves the control then returns inside of it, the thumb move independently from the finger.
- MSRangeSlider Many downloads from cocoapods, but no forks, issue or stars on github. It doesn't track touch very well, the thumb doesn't move right away, and it has the same issue as TTRangeSlider.
- MARKRangeSlider
