Expand description

Raw bindings to Objective-C runtimes

These bindings contain almost no documentation, so it is highly recommended to read the documentation of the original libraries:

Apple’s official documentation.
Apple’s objc4 source code (git mirror), in particular runtime.h.
GNUStep’s libobjc2 source code, in particular runtime.h.

Structs

objc_class

An opaque type that represents an Objective-C class.

objc_ivar
