This version includes backwards-incompatible changes to support Swift 1.2. The
previous behavior of lazy evaluation of the argument in expect(...) has been
removed since Swift 1.2 no longer supports this. Use expect { ... } if you want
the lazy closure behavior.
Using toEventually() will check that this explicit closure is used and will
explicitly fail if the closure is not provided to expect.
Along with fixes for Swift 1.2, there are a few new features:
- Added beEmpty matcher for Objective-C.
- raiseException matcher can compare an exception's userInfo
