Its own README describes the project as intentionally incompatible with Foundation so that ObjFW can provide consistent behavior across supported platforms rather than preserve Foundation quirks. ### Project history The project reached its first stable API and ABI in ObjFW 1.0 on 2023-08-29 after a long pre-1.0 period; the ChangeLog notes that 1.0 followed nearly six years after the previous 0.90.2 release. Later 1.x releases continued to expand the runtime, TLS, archive, DNS, filesystem, terminal, Unicode, and platform-support surface. ### Adoption history ObjFW is packaged in Homebrew and in several Unix-style distribution ecosystems under names such as objfw, libobjfw1, and libobjfw. Its package split in some distributions reflects the project structure: core framework, Objective-C runtime, TLS support, HID support, documentation, and small utilities built on top of the framework. ### How it is used Developers use ObjFW either as a library framework or through its helper tools. The README documents objfw-new for creating an application skeleton, objfw-compile for compiling ObjFW applications without a larger build system, and objfw-config for obtaining compiler and linker flags for custom builds. ### Why package nerds care ObjFW is interesting because it packages a non-Foundation Objective-C world: a framework, runtime, build helpers, and command-line utilities. For package indexers it is a reminder that Objective-C runtime support is not only an Apple-platform concern, and that one source project can publish both libraries and user-facing executables. ### Timeline - 2017-08-01: ObjFW 0.90 added new classes and support for Nintendo 3DS and MorphOS. - 2023-08-29: ObjFW 1.0 delivered the first stable API and ABI. - 2024-04-14: ObjFW 1.1 changed the license to LGPL-3.0-only and added ObjFWTest, associated objects, DNS caching, Mbed TLS support, and more archive functionality. - 2025-08-03: ObjFW 1.4 moved object memory management into the runtime and added runtime optimizations. - 2026-02-22: ObjFW 1.5 added color-space and image support. ### Related projects - ObjFW sits beside Foundation-compatible projects such as GNUstep rather than replacing them directly. The project explicitly chooses portability-through-ObjFW over Foundation compatibility, which makes it a distinct packaging target for Objective-C applications. ### Sources - - - - ## Security Notes No matching local secret-handling manifest was found for objfw.
