It goes into alot more detail than most courses, it would be better if it had more questions though but great especially because its free

I’m a hobby programmer and enjoyed this book. I didn’t have any difficulties with the screen shots. I could double tap on my iPad, go full screen and then zoom. With the Mac version I was able to double click and open a full screen view. In fact the iBooks, illustrations are the best I have ever used. Best of all this is free! Thank you Apple!

The screen shots and instructions do not appear to match xcode 12.5. The screen shots are too small to see in two page layout or even in one page layout. This book is just terrible.
