I know it's too late, but thought it would help somebody.

I just created a folder by myself in the project folder, called it tk.lproj. After that, i found that tk (turkmen) language in the drop-down list. Seems like Xcode automatically detects available localizations by scanning the project folder. But i wonder why it hides them out until you create a localization directory for it.
