Google APIs Client Library
This supports recent Google JSON APIs, including Tasks, Latitude, Books, URL Shortener, and others. It's processor and memory efficient suitable for iOS applications. The library includes high-level Objective-C interfaces and classes for each service, that were generated from the Google APIs Discovery Service. This lets the library model data as generic JSON dictionaries, and also with first-class Objective-C 2.0 objects with properties for each field, letting developers take advantage of Xcode’s code completion and syntax and type checking.
iOS Boilerplate - Speed up iOS Development
iOS Boilerplate is intended to provide a base of code to start with, but is not a framework. The intention is fr it to be modified and extended by the developer to fit their needs. It includes third-party libraries to save reinventing the wheel.
Molecules Source Code
Molecules is a free iPhone application that renders complex molecules using openGL on the iPhone and uses touch to rotate and zoom in. New molecules can be downloaded from the RCSB Protein databank. The author has provided the full project and source code as a download.

It provides an Objective-C API that lets you avoid low-level code without giving up the power of using OpenGL and OpenAL. Pixelwave comes equipped with useful utilities such as a particle engine, physics engine, tweening engine, debugging tools and more.
PuffPuff - iTunes released open source
PuffPuff is now at version 1.1 in the App Store but version 1.0 has been released completely as open source including graphics and sounds. It's based on the open source Cocos2D library for iPhone which incorporates ChipNumk and Box2D physics engines. Note unless you have openFeint integration you need to comment out 4 symbols or it will not build.
Qualcomm Augmented Reality SDK
Produced by Qualcomm's Austrian Research Center, it allows you to develop apps with computer vision technology that can align graphics with printed surfaces and simple 3D objects, and includes support for multiple development tools including Eclipse (Android™), Xcode, and Unity royalty-free development and distribution.
Simutrans - Open Source Transport Game
Converted from the original open source desktop game Simutrans this is the iPhone port. It's also in the App Store as a free App. It was ported by the same developer who ported openTTD to the iPhone.
Sparrow is a pure Objective C library targeted on making game development as easy and hassle-free as possible. Sparrow makes it possible to write fast OpenGL applications without having to touch OpenGL or pure C (but easily allowing to do so, for those who wish). It uses a tried and tested API that is easy to use and hard to misuse.
Sudoku Solver with OCR
In the App store but also Open SOurce, this Sudoku solver reads a Sudoku optically (using the OpenCV library) then slves it. You need Xcode 4 to build it.
Wolfenstein for iPhone
The link is an FTP download (which Firefox and IE should manage). This includes the full project, source and all game data for the iPhone Wolfenstein game. The source code is GPL but the game data isn't and so can't be used. (Read the readme_iWolf.txt file).
