I got around this issue by opening the storyboard as source code (control click storyboard -> Open As) and updating the value directly. e.g setting the font as I found the line I was working on by looking at my source control but I also could have found it by changing the font to one I am not using anywhere else and searching for it in the code to replace with the custom font. If you have no previous reference on what to set the font as look for code that prints out all fonts by using UIFont familyNames and then fontNamesForFamilyName. There are a few code examples about. But since you are using font awesome it will probably look like the example above. Could be Font Awesome 6 Free and FontAwesome6Free-Solid if you are using version 6.
