Try to uncheck iTableView library and to check iUI8 library.
On my Mac libiUI8.a is dated Dec, 2018 and is a part of B4i 6.50 Mac Builder..
Architectures in the fat file: libiUI8.a are: armv7 x86_64 arm64
So, it's possible to compile as 64bit for simulators.
But I can say nothing about your B4i Mac builder, because you use very old release - B4i 5.30.
