Linker Error in iOS (duplicate symbols for architecture x86_64)

Question

I keep on getting the following error:

duplicate symbol _llvm.embedded.module in:
/Users/name/Documents/FacebookSDKs-iOS-20150910/FBSDKCoreKit.framework/FBSD         


        

Answer 1

When I had a duplicate symbols error, I opened my project.xcodeproj XML file in a text editor and searched the duplicate symbol. You'll most likely find that FacebookSDK shows up in multiple lines with the same "id" property. Make sure you have a back up of your current project, and try deleting the duplicates (ones that have the same id) manually in this file. Save the file, compile, and see if the project runs.

You might want to try just deleting one duplicate line, and seeing if the number of duplicates (apparently you have 102!!) goes down first.
