We may want to consider adding demo apps for the two swift package libraries to ensure this can't happen again.

Good idea!
I'm trying to use local SPM in demo apps but can't figure out a correct way to do that. Do you know how to do it? @master-nevi

Sure @chiahsien, do you want that in this PR or a separate PR?

In this same PR would be fine, thank you @master-nevi !

Hi @chiahsien . I figured you'd want to use the same demo apps if possible to avoid having a whole other set of sample code and xcode projects to maintain. So I just created a new target in each of the two demo projects that consumes the Swift Package and re-uses the demo-app code. There are no changes to the original targets. I separated this task out into two commits, one for the Objective-C demo app and one for the Swift demo app so it's easier to see the changes:

Just to be sure, I tested the current Package.swift and got an error (which is expected) from the CI:

My update to the Package.swift fixes the error above.

LGTM! Thanks a lot for your help @master-nevi 👍
