Beginner here and just looking for some assistance on a few things:
Did anyone do the exercise on page 357, having controls resize base on different iPhones? Just looking for guidance.
The Crossfade code is not working for me. I tried copy and paste but still does not work. I could not find the source code either. My book is v8.3.0 but source code is v8.2.1, has this happened to anyone else?
