Casted class types are not highlighted (via as)

I'd expect as NSDictionary to highlight NSDictionary.

Thanks for these 3 (with examples!) Kyle. Vim syntax files are the worst. I'll see what I can do.

I almost got somewhere with this:

syntax match swiftThing "\v\W\u\w+"hs=s+1
syntax match swiftThing "\v^\u\w+"
highlight default link swiftThing TODO

This worked by highlighting everything that had a capital letter, followed by other letters. It almost worked because it was also overwritten by other rules. There are 2 cases this is broken with though:

if #available(OSX 10.10.3, *) {

Here it overwrites the highlight of OSX. And:

let URL = NSURL(string: "foo")

It highlights URL when it shouldn't be (or any other variable name starting with a capital letter). We could possibly handle this last case by making sure it's not followed by a = but that got pretty complex pretty quickly.

If anyone wants to take this starting point and run with it that would be awesome
