Open Source Objective C Libraries for Mac

FUSE for macOS allows you to extend macOS's native file handling capabilities via third-party file systems. FUSE for macOS is a successor to MacFUSE, which has been used as a software building block by dozens of products, but is no longer being maintained.

Google Toolbox for Mac (GTMSession) is a comprehensive collection of open source Objective-C utilities and frameworks developed by Google to support macOS and iOS application development. It consolidates reusable code components drawn from various internal Google projects, offering developers a wide range of tools for building efficient, maintainable Apple platform software. The library includes modules for networking, logging, testing, data handling, and user interface extensions, helping developers avoid reinventing common functionality. Its modular design allows developers to integrate only the components they need, improving project flexibility and performance. With well-documented interfaces and consistent coding standards, Google Toolbox for Mac serves as a reliable foundation for both small and large-scale applications. It continues to be widely used across open source and internal projects that target Apple ecosystems.

LIEL (Language Independent Extension Library) is a language-agnostic library containing solutions to various programming problems and extending the capabilities of existing frameworks and code libraries.

WFEX provides functionality for portably executing code using a variety of different execution types ("executors") from generic job objects, most notably the "tasklet" concept. It also includes synchronization primitives such as locks and barriers. This library can be included in your project to implement certain forms of high-performance computing into your projects and has bindings planned for C, C++, and Objective C. It abstracts away various concepts that are often relegated to system APIs that are frequently incompatible with each other.
