Calling a Function with NULL as Parameter

Question

I am trying to load an image with the following Code, but I have no clue how to do this in Swift.

The CGImage Reference says, that I should pass NULL as parameter, but since NULL is not part of the Swift-Language this is not possible. Do I have to use UnsafePointer and if so, how?

var img = CGImageCreateWithPNGDataProvider(CGDataProviderCreateWithFilename("/Resources/image.png"),**?**, true,kCGRenderingIntentDefault)

Thanks in advance.

You should be able to pass nil for a null value.
