Vector SIMD types in Swift

Just a heads up for this question for it to be up to date - SIMD Vectors have been announced at WWDC '15 for Swift 2.0:

SIMD Support:Clang extended vectors are imported and usable in Swift, enabling many graphics and other low-level numeric APIs (e.g. simd.h) to be usable in Swift.

So the answer from now on - yes, it's possible.
