Hi Humza,
I include the feature layer definition files in my app's bundle. When my app launches I copy the files to the app's Documents directory and then read the definitions from there to initialize the feature layers. The reason putting the files in the app's Documents directory is that should any of the definition changes I could use iTunes file sharing to update the files without having to recompile the app...
Cheers,
Shimin
