QR (matrix) code image processing classes. (So far, the iPhone section is just part of the fuller ZXing barcode processing project.)

This is a .NET web site solution that uses XSLT to transform SOAP-based web service definition WSDL files into complete code packages. The code that is generated is easy to read and update.

While SudzC supports multiple platforms, it's focus is on code generation for Objective-C libraries for iPhone development.

InAppSettingsKit is a solution to to easily add in-app settings to your iPhone apps. It uses a hybrid approach by maintaining the Settings.app pane. So the user has the choice where to change the settings.

To support traditional Settings.app panes, the app must include a Settings.bundle with at least a Root.plist to specify the connection of settings UI elements with NSUserDefaults keys. InAppSettingsKit basically just uses the same Settings.bundle to do its work. This means there's no additional work when you want to include a new settings parameter. It just has to be added to the Settings.bundle and it will appear both in-app and in Settings.app. All settings types like text fields, sliders, toggle elements, child views etc. are supported.

Active Record for Core Data was inspired by the ease of Ruby on Rails' Active Record fetching. Active Record for Core Data is a great way to simplify your Entity fetches, as well as deal with multiple NSManagedObjectContexts.

mogenerator is a command-line tool that, given an .xcdatamodel file, will generate two classes per entity. The first class, _MyEntity, is intended solely for machine consumption and will be continuously overwritten to stay in sync with your data model. The second class, MyEntity, subclasses _MyEntity, won't ever be overwritten and is a great place to put your custom logic.

C-style asserting in your unit tests is so 1980's. Tests need to run fast, sure, but you also need to be able to read them later. By making your Asserts use pure C macros and functions, you are missing all the fun of using Objective-C for unit testing!
