The following instructions will only work if building from OS X.
The following instructions will only work if building from OS X, using latest XCode with fake signing enabled.
To build RetroArch:
Open $(root)/ios/RetroArch.xcodeproj, change build type to iOSDevice then choose Product->Build For->Archiving.
After compilation finishes goto Window->Organizer->Projects->RetroArch then click the small arrow beside
the Derived Data field, this will open a finder window with the projects build files directory highlighted.
The app bundle can be found at Build/Products/* in that folder. Use scp to copy the .app bundle to the appropriate place
on your device.
To build libretro cores:
In general, to build for iOS devices, copy the configuration for OSX, then at the end add the lines:
sysroot = -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk/
CC = /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc -arch armv7 $(sysroot)

...
Other arm specific flags can be added if needed.
Finally issue the make command for the module adding 'platform=ios' at the of the command.
(e.g. 'make -f Makefile.libretro platform=ios'). Then copy the resulting .dylib file into a sub-directory of the app
bundle named modules. (e.g. RetroArch.app/modules/vba_next_libretro.dylib).
Paths:
/var/mobile/Library/RetroArch: Will be created to store both saved games and the retroarch.cfg.
/var/mobile/RetroArchGames: If this exists and is a directory it will be used as the root for game browsing.
/var/mobile: If RetroArchGames does not exist this will be used as the root for game browsing,
if another browser root is desired make RetroArchGames a symlink to the preferred path.
RetroArch.app/shaders: Contains .shader format shaders, sub-directories are supported.
RetroArch.app/overlays: Contains input overlay definitions, sub-directories are supported.
RetroArch.app/modules: Contains .dylib files for the libretro modules. The only constraint on the file name
is that it must end in .dylib, sub-directories are not supported.
Simulator:
To test in iOS Simulator you will need to create the '/var/mobile' directory on you computer, and give yourself full
access to it.
