Getting multiple thumb values

func sliderChanged(slider: MultiSlider) {
    print("\(slider.value)") // e.g., [1.0, 4.5, 5.0]
}

Range slider

slider.outerTrackColor = .lightGray // outside of first and last thumbs

Vertical / horizontal orientation

slider.orientation = .horizontal // default is .vertical

Value labels

slider.valueLabelPosition = .left // .notAnAttribute = don't show labels
slider.isValueLabelRelative = true // show differences between thumbs instead of absolute values
slider.valueLabelFormatter.positiveSuffix= " ?s"

Snap interval

slider.snapStepSize = 0.5  // default is 0.0, i.e. don't snap

Changing Appearance

slider.tintColor = .cyan // color of track
slider.trackWidth = 32
slider.hasRoundTrackEnds = true
slider.showsThumbImageShadow = false // wide tracks look better without thumb shadow
