Pathology

Pathology is a library for encoding/decoding CGPath data.

Extracting CGPath data

let bezierPath = UIBezierPath(
    roundedRect: CGRect(x: 50, y: 50, width: 200, height: 200),
    cornerRadius: 10)

let data = Pathology.extract(bezierPath.CGPath)
for el in data.elements {
    print("\(el.type)")
    print("\t\(el.points)")
}
