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

let view = UIView()

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()

Squircle with border

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)

Remove squircle

To remove the squircle from a UIView:


or directly on CALayer:


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

Remove border

To remove only the border from a squircle:
