history
Project history and usage
ObjFW is a portable Objective-C framework and runtime aimed at developers who want Objective-C without binding their application to Apple Foundation or GNUstep. 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.
