Make local variable name more expressive

[nielsandriesse]

It seems that element would also be more consistent with the documentation

[datwelk]

👎 I would argue that in this case ret is more descriptive than element.

[PatrickPijnappel]

In any case, result or returnValue would at least be better than ret, which is unnecessarily abbreviated.

[gribozavr]

I'd prefer result.

[dabrahams]

I prefer element or nextElement. It tells you about the result's semantic role, rather than just its relationship to the method API

[dabrahams]

Good naming is part of code quality. We care about the quality of the Swift source code. This may be far from the most important issue that we have to deal with, but it's still an improvement worth making.

[mrazam110]

Can you explain why it should be result instead of element?

[lattner]

This seems like a clear improvement over what is already there.

Since the documentation says Advance to the next element and return it i think return next_element would be quite descriptive.
