Originally it was:

(returns) name(params) { app {...}}

That made little sense.

So it was changed to:

app (returns) name(params) {...}

which more closely matches the modifier idea in C/Java and the likes.

At the same time, the former was deprecated (except there probably is no
mention of this anywhere). It should, IMO, be removed in future versions
of swift.

So what you consider cleaner is what I would stick with.
