class-dump

class-dump is a command-line utility for examining the Objective-C segment of Mach-O files. It generates declarations for the classes, categories and protocols. This is the same information provided by using 'otool -ov', but presented as normal Objective-C declarations.

Version 4.0.0 is a complete rewrite in Swift.

The latest version and information is available at:

http://stevenygard.com/projects/class-dump

The source code is also available from my Github repository at:
