Preference between Array<Type> vs Type[] about swift-style-guide HOT 7 CLOSED

Those are the same – Type[] is syntactic sugar for Array<Type>.

I think we should go with Type[] in the same way we write Int? rather than Optional<Int>. Arrays and optionals are so common that there are these (IMHO) readable and understandable shortcuts; we should use them!

Yes - syntax sugar is there for a purpose - we should use it.

Yeah the Apple book says to prefer using the Type[] variant: "Although the two forms are functionally identical, the shorthand form is preferred, and is used throughout this guide when referring to the type of an array.”

Very good points, I think the parallel between this and Int? vs Optional<Int> is enough to end the discussion. Type[] is definitely the way to go!

Just added this in 9932802. Thanks!

Of course, I had to say [Type] rather than Type[] now. ;]

Yep :] I think with the addition of the Dictionary sugar it makes even more sense to add a section on it. [Type] looks soooo weird to me though...hope I'll get used to it soon!

The C++ style Foo<Bar> is very familiar but I think I can see myself getting used to the new Swift style. I do like how the type declaration "looks like" the literal itself, which helps.
