Is the book "Programming iOS8" on schedule? It says release date in September 2014 but only few chapters are written. Is there a way to have a preview of it before purchasing?

Thanks for your interest in Programming iOS8. Unfortunately there isn't a preview of this book on the catalog page. Currently the early release ebook is the only version that is available. Early release ebooks enable you to get the book as it is in progress, and when the final version is released you will get that version. The release date is actually estimated to be November 2014. More information on O'Reilly early release ebooks can be found here:
I hope this helps and have a great day!
