Usage

import UIKit
import CanvasView

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        let canvas = CanvasView(frame: CGRect(x: 0, y: 0, width: 400, height: 300))
        let borders = CanvasPath()

        borders.strokeColor = UIColor(white: 0.9, alpha: 1)
        borders.move(to: CGPoint(x: 20, y: 50))
        borders.addLine(to: CGPoint(x: 350, y: 50))
        borders.addLine(to: CGPoint(x: 350, y: 275))
        borders.addLine(to: CGPoint(x: 20, y: 275))
        borders.addLine(to: CGPoint(x: 20, y: 50))

        let white = CanvasPath(rect: CGRect(x: 20, y: 50, width: 330, height: 75))
        white.fillColor = UIColor.white

        let blue = CanvasPath(rect: CGRect(x: 20, y: 125, width: 330, height: 75))
        blue.fillColor = UIColor(red: 0, green: 0.224, blue: 0.651, alpha: 1)

        let red = CanvasPath(rect: CGRect(x: 20, y: 200, width: 330, height: 75))
        red.fillColor = UIColor(red: 0.835, green: 0.169, blue: 0.118, alpha: 1)

        canvas.paths += [borders, white, blue, red]

        view.addSubview(canvas)
    }
