CI/CD Fails because missing files needed for build, but not wanted on public repo in a .gitignore

I’d recommend these two possible approaches:

1. Add the files to a private Git submodule and add it to your dependencies: https://docs.codemagic.io/building/access-private-git-submodules/

2. If there are not too many files, then you could encrypt them in Codemagic and then add them through environment variables.
