Getting error "No such module" using Xcode, but the framework is there

Question

I'm currently coding in Swift, and I've got an error:

No such module Social

But I don't understand, because the module is in my project, declared in "Linked frameworks and Libraries" and in "Embedded Binaries".

The frameworks is in Objective-C, so I wrote a Bridge Header for it.

Please, how can I make Xcode recognize the framework?
