Swift 2&3: How to Use CGBitmapContextCreate

Question

I have the following code:

let ref:CGContextRef = CGBitmapContextCreate(nil , 200, 130, CGImageGetBitsPerComponent(self.CGImage), 0, CGImageGetColorSpace(self.CGImage), CGImageGetBitmapInfo(self.CGImage))

The problem is that I get this error:

Expression does not conform to type 'NilLieralConvertible'

What should I pass in instead of nil for the first argument and why?

The problem is the last argument. Make the last argument CGImageGetBitmapInfo(self.CGImage).rawValue.

It's because the nature of bitmask types has completely changed in Swift 2.0. And CGBitmapInfo is a bitmask type.

Works for Swift 3 too
