How to pass an error pointer in the Swift language?

Question

I am attempting to pass an error pointer in swift and am unable to do so. The compiler complains that \"NSError is not convertible to \'NSErrorPointer\'\".

var e

This suggestion is up for discussion, but some engineers would prefer to use the golden path syntax:

var maybeError: NSError?
if let results = context.executeFetchRequest(request, error: &maybeError) {
    // Work with results
} else if let error = maybeError {
    // Handle the error
}
