I've decided to open the source code for two of my real estate apps currently in the app store: Home Finder Real Estate Tool and Find an Apartment (links are to the app store). By no means am I claiming the code is great or adheres to best practices (and the only documentation is a README and inline comments), but I hope the source can serve as a reference of a decently sized app for others. Some of the technologies used are Core Data, augmented reality, Map kit, REST calls, and XML parsing. The code is a single XCode project with two targets, one for each app. The source code is released under the MIT license. Source on GitHub: http://github.com/baalexander/Find-an-Apartment Enjoy!
