-lsqlite3 causing Apple Mach-O linker errors

Question

I installed the Facebook SDK and followed one of their tutorials in order to provide some very basic FB functionality to my app. The app, and the FB integration seems to work just fine so I think I did a decent job with the tutorial. When I attempt to Archive the project so that I can throw a build up on TestFlight, I get a Failure due to 15 linker errors, that looks like the below text (I copied it from the app log). It seems to be related to lsqlite3.0, which the FB tute said to add to the build settings under 'other linkage'. I am not quite sure what to do to resolve. Could I get some advice? That would be super awesome, thanks! Here are the errors:

Archive uses a release build by default and your linker setting are only set for debug. Check that your linker settings are valid for release build.
