It seems that each final version of the Coffee Quest App (chapters 10 - 13) fails to load. All have the same error. Did other people find the same thing?
As a workaround, I downloaded the iOS12 version & worked with those files which still run fine.
I had this problem also using Xcode 11.4.1. The build log indicates that it is a ‘Permission denied’ problem while running Pods-CoffeeQuest.frameworks.sh.
However, using the iOS 12 files as per @and1’s suggestion works.
As an aside, not sure why it is necessary to use Cocoapods in order to demonstrate the use of MVVM. It seems like an unnecess complication.
Seems to be related to permissions around Cocoapods and something changing with the latest version of either pods or Xcode, either way, this fixed it for me:
$: pod deintegrate && pod install
This will remove and install the pods and set the proper permissions, I was up and running after this.
