iOS Question Simulator build fails using internal iPhone library

xcode version: 14.3
macbook macOS version: Venture 13.2.1
B4I version: 8.3
Build Server version: 8.1 (uploaded with B4I version 8.3 upgrade)

My program compiles normally to an Apple device, but fails to build when I include the iPhone internal library. I get these error messages:

[IDE message - 8:59:43]
