Chapter 9 - project differs from book

In the book the project has 3 different indicators to show the state of the animation:

the project included with the book has only 1 :confused:

@icanzilb Thanks very much for your question, and my apologies for the delay in responding. I ran both the started, and final versions of the project, and you are indeed correct. I have flagged the author, and hopefully we’ll get to the bottom of this!

In the early betas, KVO worked for all of the properties, and it broke super late in the process IIRC, we changed the project but didn’t have time to fix all the screenshots.
