How to create a rounded corner rectangle using BezierPath

 var roundRect = UIBezierPath(roundedRect: , byRoundingCorners: , cornerRadii: )

Or for an example with values:

var roundRect = UIBezierPath(roundedRect: CGRectMake(0, 0, 100, 100), byRoundingCorners:.AllCorners, cornerRadii: CGSizeMake(16.f, 16.f))
