Change slider direction

Question

I would to change a slider\'s direction from right to left. I want 0 to be on the right side.

For example:

My slider:

let slider = UISl         


        

Answer 1

in my opinion its more easier and more official to use following:

slider.semanticContentAttribute = .forceRightToLeft

Answer 2

Just flip the slider horizontally:

slider.transform = CGAffineTransform(scaleX: -1, y: 1)

Answer 3

Or take the slider value with

let realValue = slider.maximumValue - slider.minimumValue + slider.value;

And set it using

slider.value = slider.maximumValue - slider.minimumValue + realValue;

Like that the slider does not need to be visually transformed, and will still respond correctly to any other input methods (keyboard, accessibility input, etc)
