delegate problem
Hello! I had issue with delegate. When I tried several methods to assign delegate to another view controller, not that one, which contains HorizontalDial, I had problem: inside VCs delegate is the same object, but inside HorizontalDial object delegate is nil. I tried a lot of fixes in a good way, but helped me only this kludge:

private var delegateTemp: HorizontalDialDelegate? = nil @IBOutlet public weak var delegate: HorizontalDialDelegate? { set { delegateTemp = newValue } get { return delegateTemp } }

As you see, I changed delegate from AnyObject? to protocol optional, and have buffer variable delegateTemp. It's not in clean way, but it's works. It's not a big deal, but I bet you can fix it

Correct the spelling of CocoaPods in README

This pull requests corrects the spelling of CocoaPods 🤓 https://github.com/CocoaPods/shared_resources/tree/master/media

One day I’ll make a bot that looks through the READMEs of all Pods, looks to see if it uses “Cocoapods” and PRs “CocoaPods” :D

adding spring loaded swipe action?

Can it be possible to add this feature: when swiped, the wheel keeps going for a while based on spring load, snapping to a value, like the wheel of fortune I guess ;-)

Setting minimumValue & maximumValue - Doesn't work

Hi,

Setting min & max values (in code or Storyborad) doesn't limit the scrolling and/or prevents from getting values out of range set.
