Add support for Core Data model

- This also fixes and issue where the order of the warnings was not in

- Added support for tilde expansion
- Added support for relative paths
- Always return absolute paths for the Podspec.

This was caused by not reloading the user project from disk and losing
previous changes done to the same project.
