Build warnings in PrefUIViewController.xib, identifiers not unique

[low-batt]

System and IINA version:

• macOS 12.2.1
• IINA 1.2.0

Expected behavior:

IINA builds in Xcode without warnings.

Actual behavior:

I get these two warnings when I build IINA+ in Xcode:

/* com.apple.ibtool.document.warnings */
/Users/low-batt/Documents/builds/iina-plus/iina/iina/Base.lproj/PrefUIViewController.xib:Oba-nc-n1C: warning: Multiple objects using identifier "AccessoryLabelThumbSize" (Identifiers must be unique) [9]
/Users/low-batt/Documents/builds/iina-plus/iina/iina/Base.lproj/PrefUIViewController.xib:3kE-zA-EH8: warning: Multiple objects using identifier "AccessoryLabelThumbSize" (Identifiers must be unique) [9]

This is a regression.

Steps to reproduce:

Build with Xcode 13.2.1.

• [x] MPV does not have this problem.
• [x] Official IINA does not have this problem.

How often does this happen?

Every build.
