Chapter 6 says " Open AppDelegate.swift and change the IP address in the sendPushNotificationDetails(to:using:) …" but the project we created in Chapter 4 does not have any method named “sendPushNotificationDetails”. You can even search for this term in Chapter 4 and it does not exist, so where did it come from?? Even Chapter 5 doesn’t say to add it.
I see it exists in Chapter 7 but when and where did we decided to even add it??
Even the downloaded sources from Github does not have any method with that name in their project 4 or 5.
Upon exploring, it gets even worse. The starter project for Chapter 7 doesn’t even have the “sendPushNotificationDetails” method either! So Chapter 6 is referencing a method that we haven’t even added yet until we complete chapter 7!
