I'm sure we've all gone through the first part of the chapter 7 tutorial in the simulator where you select a date on the picker, and then press the 'Select' button for the alert to popup with the selected date from the picker. But if you read the actual alert message, it gives the day after the one you selected, e.g. you select Jan 1, and the alert message will say Jan 2.
It's like this when I follow the steps in the book, as well as running the source code I downloaded from this site. Did I miss something, or is there a hiccup in my configuration? It does the same in both the iPhone 6 and 6.1 simulators. Anyone have any ideas?
