A simple range slider made in Swift.

This control is IBDesignable and uses the target-action pattern for change notifications.

In order to be notified when either thumb value changes, register for .ValueChanged:

let rangeSlider = RangeSlider(frame: frame)
view.addSubView(rangeSlider)
rangeSlider.addTarget(self, action: "rangeSliderValueChanged:",
                         forControlEvents: .ValueChanged)

The range slider can be customized and information can be accessed through these properties :

• minimumValue : The minimum possible value of the range
• maximumValue : The maximum possible value of the range
• lowerValue : The value corresponding to the left thumb current position
• upperValue : The value corresponding to the right thumb current position
• trackTintColor : The track color
• trackHighlightTintColor : The color of the section of the track located between the two thumbs
• thumbTintColor: The thumb color
• thumbBorderColor: The thumb border color
• thumbBorderWidth: The width of the thumb border
• curvaceousness : From 0.0 for square thumbs to 1.0 for circle thumbs
