This is the catalogue of iOS/Objective-C Open Source projects. I created it to have a fast access to any Mac/iOS-related projects I recently Github-starred or explored.
It will grow as fast as it is possible with my ability to add/explore new projects around the net, Github, etc.
If you liked it, feel free to suggest any new projects that are not present in the current list.
Also I keep another catalogue of projects: it contains the list of candidates for this catalogue. After I am sure enough that a particular candidate-project deserves its place here, I move it here from the list of Candidates.
Note! This catalogue also includes a number of projects which are not open-source but are still somehow related to a development of iOS/Objective-C applications.
Both Github version and Web version of this catalogue are available.
