Report

What did you do?

I added swift packages to pods project in post_install hook but got the following error on project build:

What did you expect to happen?

I expected I will be able to build and run project after adding swift package to the pod targets.

What happened instead?

Got error No such module 'Algorithms' where Algorithms is a target in the swift-algorithms package.

I don't think it's a cocoa pods issue, it's more a way of how Xcode works.

See https://github.com/mfazekas/pods-spm-dep-poc/blob/main/README.md#user-content-swift-import-paths

And the code to address this is here:
https://github.com/mfazekas/pods-spm-dep-poc/blob/b97b862ec667fed98085d133d8fdf7ff30ce60e7/spm_dependencies_poc.rb#L66-L73
