duly: Library not loaded: Combine

[BeauNouvelle]

Running into this issue after following the setup steps as described in the Readme.

xcinfo

dyld: Library not loaded: /System/Library/Frameworks/Combine.framework/Versions/A/Combine
  Referenced from: /usr/local/bin/xcinfo
  Reason: image not found
Abort trap: 6

EDIT: I'm wondering if this has something to do with me trying to run this on Mojave..

We're using Combine so you need to have Catalina.

We could probably replace it with RxSwift but it was intended as our Combine live learning example. :)

No problem at all. Makes sense to me. I've created a PR to add this to the readme.
