I see there’s no “duplicate” when I right click on a .xib. So is the way to do it: just to go to finder, copy the file to another name, and then drag it to my resources? Would that be all I’d need to do?
[Note: just wondering if there’s other files or settings I need to bother with.]
Yes, that’s most of what’s needed. Make sure to open the nib file and verify that the connections are as you want them to be. It will act like any file you duplicate. Just give it an original name and make sure it’s saved in the correct folder before you import it into the project.
