Swift, polare circle : I have to draw 12 points in a circle with different radiant. From point 1, draw a line to point 2, from point 2 to 3, etc.

I can not find a formula, but I think it's something with polar circle?

Is anyone working with it and maybe want to share with me?

See the picture, which might explain better than I can?
