Ever wanted to have one or more circles like in the Fitness App from Apple. Sure, you looked at HKActivityRingView like me and were absolutely, terribly disapointed about the pretty useless non-use-case? ;-)
Have a look here.
You simply need to call ArcView with a value of 0 to 1 for filledSlice — and you probably want to tweak a bit ArcView itself, e.g. private let colors: [Color] which, if you don't need a Gradient, you can simply populate with one single color. Gradients are way cooler though!
