Squircle is an UIView extension, and can be used in different ways:

let view = UIView()
view.squircle()

just apply conventional squircle radius to the view. If the view is a square, i'll obtain the same effect as iOS springboard icons, if it's a rectangle i'll obtain rounded corners based on a square built on smallest side.

Squircle is also an CALayer extension, permitting you to add a squircle mask directly on a layer. Rules are the same as the UIView methods, invocation is:

let layer = CALayer()
layer.applySquircle()

If you want to apply squircle with a border use the dedicated methods:

let view = UIView()
view.squircleWithBorder(width: CGFloat, color: UIColor)

let layer = CALayer()
layer.applySquircleWithBorder(width: CGFloat, color: UIColor)

To remove the squircle from a UIView:

view.removeSquircle()

or directly on CALayer:

layer.removeSquircle()

If a border has been added to the squircle, both functions above will remove it too.

To remove only the border from a squircle:

view.removeSquircleBorder()

or directly on CALayer:

layer.removeSquircleBorder()
