================================

This release is compatible with Xcode 7 beta 4 (Swift 2.0).

Note to Carthage Users: You must explicitly give this version for Carthage to install.

    github "Quick/Nimble" "v2.0.0-rc.2"

Backwards Incompatible Changes
------------------------------

- swift: Expectations now properly handle the new Swift error handling syntax.
  This means expectations implicitly allow throws and will fail with a useful
  error message if a closure throws one:

    expect { try throwAnError() }.to(equal(1)) // Failed - Expected to equal 1, got an unexpected error thrown: ...

- objc: expectAction() is now a macro that requires an Objective-C block instead of building an implicit block:

    Old:
        expectAction([obj raiseException]).to(raiseException(...));
    New:
        expectAction(^{ [obj raiseException]; }).to(raiseException(...));

Additions
---------

- You can now specify custom error messages for expectations. This is useful
  for large integration tests, where an expectation is usually a sanity check to
  a larger operation:

    expect(1).to(equal(2), description: "Just checking equality!") // failed - Just checking equality!

- swift: Fixed ≈ precedence
- swift: beAKindOf() and beAnInstanceOf() emits useful errors when trying to
  compare against Swift Types. This is not allowed in Nimble because the Swift
  compiler already enforces this.
- swift: Added throwAnError() matcher for verifying the behavior of closures that throw an error:

    expect { try somethingDangerous() }.to(throwAnError())

- objc: NMBObjCMatcher initializers are now public
- objc: contain() matcher now accepts variadic arguments. Each value passed to contain() is expected to be in the container:

    expect(@[@1, @2, @3]).to(contain(@1, @2)); // passes
