This release of class-dump has been updated for Mac OS X 10.9 Mountain Lion. It requires the 10.9 SDK, but still targets 10.8. You can download this version from the class-dump project page, and the latest source is always available from the class-dump git repository at Github.
class-dump now parses extended types (available only in protocols), so you get more precise type information on protocol methods. It also recognizes the “arm64” architecture. For a complete list of changes, see the class-dump Release Notes.
You can send but reports to me at nygard at gmail.com, or add it to the project’s Issue Tracker at github.
