attempted to initialize an object with an unknown UUID

Question

I have taken SVN check-in for a project. Thereafter I have installed pod via terminal. After installation of pod there are few warning stating

Answer 1

My colleague and I spent hours trying to figure out how to fix a similar error:

[!] `` attempted to initialize an object with an unknown UUID. `12B87A081D0745C6D77F7885` for attribute: `file_ref`. This can be the result of a merge and the unknown UUID is being discarded.

What fixed it for us:

1. identify the file that the "unknown UUID" referred to, in the .pbxproj file; in our case, it was libPods-.a
2. find that file in the file browser in XCode
3. delete the file within XCode
4. rerun pod install
