Hello all!

I've built my own static library with components to be reused in my project, and recently had the need to update a bunch of classes. Specifically, some methods' signatures were changed due to the fact that some classes changed names.

What happens now is that the library compiles fine on its own, but, when added to an app project, the project fails to link:

The curious thing is that after a lot of project cleanups (both in the app and the lib projects), I still get the same issue. Even after starting a new project, the problem is still there.

I've also taken care to restart Xcode between a clean and a build a couple of times, but no good.

Any ideas on where to look?

Thanks in advance
