SWIFT 3.x + 4.0 I've modified the example for Swift 3 and added few lines to centralise the rectangle in the UIView

func roundRect()
{
    // Size of rounded rectangle
    let rectWidth:CGFloat = 100
    let rectHeight:CGFloat = 80

    // Find center of actual frame to set rectangle in middle
    let xf:CGFloat = (self.frame.width  - rectWidth)  / 2
    let yf:CGFloat = (self.frame.height - rectHeight) / 2

    let ctx: CGContext = UIGraphicsGetCurrentContext()!
    ctx.saveGState()

    let rect = CGRect(x: xf, y: yf, width: rectWidth, height: rectHeight)
    let clipPath: CGPath = UIBezierPath(roundedRect: rect, cornerRadius: rectCornerRadius).cgPath

    ctx.addPath(clipPath)
    ctx.setFillColor(rectBgColor.cgColor)




    ctx.closePath()
    ctx.fillPath()
    ctx.restoreGState()

}
