Swift draw shadow to a uibezier path

Question

I have a strange question. Even though I did read a lot of tutorials on how to do this, the final result only shows the bezier line, not any shadow whatsoever. My code is

Answer 1

I take this example straight from my PaintCode-app. Hope this helps.

//// General Declarations
let context = UIGraphicsGetCurrentContext()


//// Shadow Declarations
let shadow = UIColor.blackColor()
let shadowOffset = CGSizeMake(3.1, 3.1)
let shadowBlurRadius: CGFloat = 5

//// Bezier 2 Drawing
var bezier2Path = UIBezierPath()
bezier2Path.moveToPoint(CGPointMake(30.5, 90.5))
bezier2Path.addLineToPoint(CGPointMake(115.5, 90.5))
CGContextSaveGState(context)
CGContextSetShadowWithColor(context, shadowOffset, shadowBlurRadius,  (shadow as UIColor).CGColor)
UIColor.blackColor().setStroke()
bezier2Path.lineWidth = 1
bezier2Path.stroke()
CGContextRestoreGState(context)
