Result of call is unused

Question

Right below the second comment, I receive an error of \"Result of call to \'taskForDeleteMethod\' is unused. Why is this when I use the results and error in the closure followin

Answer 1

You are confusing the results variable, which is, indeed, used inside the closure, and the result of the taskForDELETEMethod call itself, which is NSURLSessionDataTask object.

From the examples of using taskForDELETEMethod that I was able to find online it looks like it is perfectly OK to ignore the return value, so you can avoid this warning by assigning the result to _ variable, i.e.

let _ = taskForDELETEMethod {
    ... // The rest of your code goes here
}
