Congratulations, you have just (depending on NSArray-implementation details)
"improved" your loop from from O(N) to O(N^2). Don't do this.

Not if the array contains objects that are equal to one another. (It’s also a
fairly expensive method, and the

You can add a counter, which is pretty easy. Or you can call
-enumerateObjectsAtIndexes:options:usingBlock:, which passes the index as well
