Swift return type clarification

I see a Swift function written as follows:

func calculation(imageRef: CGImage) -> (red: [UInt], green: [UInt], blue: [UInt]) {

 ...
 ...
}

I need to know what is the return type in the function above. I am unable to relate it to any of the known types & also what is its equivalent in Objective-C if any at all? What's the way to translate this function to Objective-C?
