How to add external file to a project?

[Rameshv]

I wanted to copy a file (one zip) to the app base path when building it. The zip file is the input to the app. Is there a way to do it. I have tried adding the file on the sources_build_phase using the project.file 'MyStory.zip'. But it breaks. project.file 'MyStory.zip' always returns nil.

I am new to iOS development. So any help much appreciated.
