Swift version error when trying to generate ObjC docs

[jessesquires]

Steps

Generate ObjC docs for JSQSystemSoundPlayer. With this build script. (without specifying a --swift-version)

Version

Jazzy 0.5.0

Error

Unable to find an Xcode with swift version 2.1.1. (RuntimeError)

Fix

Specifying a Swift version fixed it: jessesquires/JSQSystemSoundPlayer@ad2b3f9

The fix here was pretty easy/straight-forward, but feels really odd to specify a Swift version for generating ObjC docs.

---

It looks like this was fixed by release 0.6.0, which now defaults to Swift 2.2. However, presumably this will break when the next version of Swift is released?

Possible solution

Should ObjC simply use the latest toolchain/runtime?

I've been specifying --swift-version $(swift --version | head -n1 | awk '{print $4}') to get around this for now.

I'll close this as a duplicate of #427, since it will achieve the same result.
