How do I re-write this code into Objective-C?

It's right here: 

func addVote(countOption1 :String) ->String {

                 let result = countOption1 + countOption1

                            return result


                     }

Unfortunately I don't know how to convert Parse.com's Starter Project file into Swift, since it's formatted in Objective-C. This is the only code I've added (so far) to my starter project but I need to write it in Objective-C to fit the template. The app I'm working on is supposed to be a bunch of different polls where users can vote for different options and view the results of the poll after they've taken them.

Here is the equivalent function in Objective C:

- (NSString *) addVote:(NSString *) countOption1 {
    NSString *result = [countOption1 stringByAppendingString:countOption1];
    return result;
}

In this case, the first NSString in parentheses would be the type of object being returned from the function. addVote is the name of the function, with one parameter, also of type NSString. Since you seem to be adding them together and returning them in the function, the stringByAppendingString function call will get you the results you seek.
