Hi yonaskolb,

You do a great job. But I met some build error when I build swagGen

My env is

Mac OS X EI Capitan 10.11.6
Xcode 8.0 (8A218a)
$ swift --version
Apple Swift version 3.0 (swiftlang-800.0.46.2 clang-800.0.38)
Target: x86_64-apple-macosx10.9

The error log is:

It is ok when I upgrade the xCode. withUnsafeMutableBytes is the new api for ContiguousArray just after xCode 8.0
