问题
In Xcode have added two localizations, German and English. I am following documentation on Apple regarding "Use Base Internationalization" which is obtained by going to the project, clicking Info
and pressing on the checkbox.
If I do this, it launches a pane or page which is empty.
IE:

How do I get it to be populated, or otherwise be in a situation to select the relevant resource file?
回答1:
The answer is to localize your storyboards. Go to storyboard, there is a button called localize. If you do this, the pane is no longer empty.

"This could happen if Base Internationalization was active before then disabled and files deleted manually.
- Create Base.lproj folder in your project folder using the finder.
- Move your main story board to it also using the finder.
- Fix the reference to it from Xcode.
- Remove app from device, clean & build your project.
All will be back to normal."
