I got thru chapter 5 ok. Part way thru chapter 6, there was some code that should have shown some alerts when doing a build and run. These didn’t appear, so I went over my code changes and didn’t really see anything. I then created a new 06-dependency-injection-mocks-org, took the code from pg 104, and put it in stepCountController.swift, and built and ran it. No alert displayed.
Maybe the real question is should I have used the Starter project from Chapter 6 or moved forward with the Chapter 5 code while working on the Chapter 6 pdf?
Just ran into this as well. Please fix the material for other users if you didn’t do that yet. I’ve lost some time on this diffing the final materials with my project halfway through the chapter.
