@HamzaGhazouani will you be able to review and approve this PR?

Hi @spaluchiewicz, thanks for your contribution, I will look at it soon, it will be nice if we add an example of this feature in the sample

Hi @spaluchiewicz,

Thanks for your contribution.
We should do some changes before the merge:

• Add documentation to circleInitialAngle property
• Add documentation and explanation to func rotate(around center: CGPoint, with degrees: CGFloat), the second parameter is in radian and not degrees.
• We should not modify the CircularSliderHelper.circleInitialAngle because it can be used by other instances of circular slider and we will get errors (we should remove it and use an instance property instead)

For the example, we can just change the initial angle of the last example (circular) in the tab bar

Thanks

Approved by mistake

Should I create a new PR or can I contribute to the existing one?
