Question

I have a project with facebook auth provided by sdk downloaded from developers.facebook.com. Everything worked fine until I added Parse libraries. Now I have linker error with following text

clang: error: linker command failed with exit code 1 (use -v to see invocation)

any advice ?

Answer 1

You didn't add some frameworks or libraries to the project. For instance SLRequest requires social framework.

Answer 2

The problem happened because I imported spare frameworks from Parse when I needed to import only Bolts and Parse
