Calling a Function with NULL as Parameter
swift
Solution
You should be able to pass `nil` for a null value.
Problem
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.
