Undefined symbols for architecture x86_64 when using ios_unit_test

[mattdornfeld]

I'm running XCode 13.3, Bazel 5.1.1, and rules_apple 1.0.0

I'm running into an issue where I'm building a swift_library that has an spm_pkg as a dep. I'm then specifying that swift library as a dep for an ios_unit_test. When I try to build that target I get this error. Seems like it's not finding the Foundation module?

bazelbuild/rules_apple#1656

I am curious to know how your example differs from the ios_sim example. Can you post your BUILD file?

Seems to be pretty similar
