About:
libobjc2 is a modern, open-source Objective-C runtime library designed as a drop-in replacement for the GNUstep runtime. It provides robust support for modern Objective-C features, including non-fragile instance variables, automatic reference counting (ARC), and blocks, making it essential for running Clang-compiled Objective-C code on non-Apple platforms.

Key Features:

Supports modern Objective-C features like ARC and blocks
Provides a compatible API for cross-platform development
Enables use of Clang compiler on Linux and BSD systems
Actively maintained by the GNUstep community

Use Cases:

Building and running GNUstep applications on Linux
Compiling Objective-C code with Clang outside of Apple's ecosystem
Developing cross-platform applications that use Objective-C

Alternatives:

GNUstep Runtime (legacy) – libobjc2 is the modern successor, offering better performance and full support for ARC and newer language features.
