ld: 76 duplicate symbols for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

This could be a possible duplicate (as I have searched everywhere), but I still could not solve it. Thanks in advance

Answer 1

If you are using the Newer SDK of FB named "FacebookSDKs-iOS-20150910.zip" Then due to app thinning It might not work in Xcode prior to v7.

So either try it in latest XCODE v7

or

Try to use Older one "FacebookSDKs-iOS-20150813.zip"

Answer 2

When using the AWS Mobile SDK for iOS and Facebook SDK together, you should not import Bolts.framework in your project. If you remove it, it should compile.
