Swift version: 5.2
UIBezierPath
is a simple and efficient class for drawing shapes using Swift, which you can then put into CAShapeLayer
, SKShapeNode
, or other places. It comes with various shapes built in, so you can write code like this to create a rounded rectangle or a circle:
let rect = CGRect(x: 0, y: 0, width: 256, height: 256)
let roundedRect = UIBezierPath(roundedRect: rect, cornerRadius: 50)
let circle = UIBezierPath(ovalIn: rect)
You can also create custom shapes by moving a pen to a starting position then adding lines:
let freeform = UIBezierPath()
freeform.move(to: .zero)
freeform.addLine(to: CGPoint(x: 50, y: 50))
freeform.addLine(to: CGPoint(x: 50, y: 150))
freeform.addLine(to: CGPoint(x: 150, y: 50))
freeform.addLine(to: .zero)
If your end result needs a CGPath
, you can get one by accessing the cgPath
property of your UIBezierPath
.
