Q:

How to apply localization without Storyboard

I don't use storyboard or xib for this project (full code)
When I add new localization, it shows no file in the list, and when I press Finish, no folder created.

A:

You need a Localizable.strings file. If you already have that, select the file in the left panel. Then, click the button that should be in the right panel that says "Localize..."

Once you do this, you should be able to add other localizations the way you were trying to.
