  • possible duplicate of [Undefined symbols for architecture armv7](http://stackoverflow.com/questions/6429494/undefined-symbols-for-architecture-armv7) – sage444 Jan 06 '15 at 11:59
  • You need to look at the full linker output, it will tell which symbols are duplicate the the files they are in. – zaph Jan 06 '15 at 12:00
  • i have looked already but having still issue ...can you please help – Darshan Jan 06 '15 at 12:02
  • There may be some of the files / images being duplicated in your project. The complete linker error will be having the name of the file inside it. – Henit Nathwani Jan 06 '15 at 12:03

yes simply remove the Bolts framworks which also somehow already included in FB SDK

I had the same issue with the 91 duplicates. What worked for me was simply to remove the Bolts.framework which seems to be somehow already included in Facebook new SDK.

In my case, i found the files that duplicate symbol in project navigator, and delete them select Remove Reference, then drag these files in finder to Xcode project navigator select Create group and the correct target, don't check Copy item if needed, it work
