SCM (Subversion + XCode) doesn't import .a file

Question

Hi folks, I have a simple question:

My XCode project has a file called someLib.a, which I can see both inside the Xcode project and in the project's directory if I Reveal it in Finder.

As usual, I made an import operation through the SCM by selecting the projects folder, however, If I make a checkout afterwards and open the project I no longer can see the someLib.a in the project's directory and I have a broken reference to the file inside the project.

It seems SCM is ignoring this kind of file for imports, if I explore the repository folder it isn't there, how can I handle this?

Thanks
