Any luck working through this in a playground?

I'm following along at home, but I can't get CIImage objects to work in a swift playground? Anyone have any luck with this?

Maybe it's a bug of playground , because it works as below code:

import UIKit

let image = UIImage(named: "cover")

let gaussianBlurFilter = CIFilter(name: "CIGaussianBlur")
gaussianBlurFilter.setValue(CIImage(image: image), forKey: kCIInputImageKey)
gaussianBlurFilter.setValue(10, forKey: kCIInputRadiusKey)

let ctx = CIContext(options:nil)
let cgImage = ctx.createCGImage(gaussianBlurFilter.outputImage, fromRect:gaussianBlurFilter.outputImage.extent())

UIImage(CGImage: cgImage)
