Useage
Shimmer is super easy to get started with.
Simply create a ShimmeringView or ShimmeringLayer and add your content.
// Setup ShimmeringView
let shimmerView = ShimmeringView(frame: self.view.bounds)
self.view.addSubview(shimmerView)
// Setup the view you want shimmered
let label = UILabel(frame: shimmerView.bounds)
label.text = "This is my shimmering text"
// Add the view you want shimmered to the `shimmerView`
shimmerView.contentView = label
// Start shimmering
shimmerView.isShimmering = true
// To stop shimmering.
shimmerView.isShimmering = false
