The default XCode project built by Rhodes 5.0.2 sets the "Deployment Target" of "rhorunner" to iOS 6.0. However, when I set it to iOS 7.0, XCode fails to build the app for the iPhone Simulator or Device with many "Apple Match O-Linker Errors".

System:
- Rhodes 5.0.2
- Ruby 1.9.3
- Mac OS X Yosemite 10.0.1
- XCode 5.1.1 and iOS 7.1 SDK

Steps:
- delete everything under "project" in the Rhodes app folder to have a clean slate.
- Run rake build:iphone:setup_xcode_project in the Rhodes app folder to create XCode Project.
- Open project with XCode.
- Project can be built for iPhone Simulator and Device.
- Change the "rhorunner" Deployment target to iOS 7.0 and the project Deployment target to iOS 7.0.
- XCode is now unable to build the project for simulator or device.
