What's new in ObjectiveC

+2 NewiOS · macOS · tvOS · watchOS

The Objective-C runtime exposes a C API for inspecting and manipulating classes, methods, instance variables, properties, and loaded images at runtime, backing the dynamic features of the Objective-C language.

The 27 SDK adds 2 APIs, with no deprecations or removals. One addition is objc_copyImageHeaders, which returns the runtime's loaded Mach-O image headers.
