Xcode custom fonts show up in Attributes Inspector, but only Regular is selectable

Question

I added a custom font to Xcode. And in the Attributes Inspector, FontFamilly is visible, but only Regular can be selected.

Anyone know how to solve this problem?

Adding files inside the project

Add font files to info.plist

Check Target Membership

After selecting Font as Custom in the Attributes Inspector, the added font family is confirmed.

However, Bold or Extra Bold are not shown in Style, only Regular is shown.
