Apple Pay & Gift Cards

Had a chance to try out Apple Pay? With support for iPhone 6, the new iPhone 7 and Mac OS Sierra, I've received a number of positive comments about the online experience. For those who haven't seen the user interface, it's pretty straightforward. With your iDevice or desktop browser configured, you'll see a new Apple button as part of the checkout experience:


What's nice is that once you arrive at this screen, just click the Apple button and you're done. A very streamlined process, Apple Pay makes for a nice alternative to Paypal.

Store Gift Cards

Along with Apple Pay, we've also received flattering requests for store gift cards. I'm pleased to announce these are now available. With the holidays fast approaching, folks can now purchase cards for a various amounts and have them sent to third parties. If you've enjoyed the book, feel free to spread the word and obtain a gift card for a fellow developer, student or collegue.

Advanced Sorting

If you follow the latest happenings with the book, you've probably received news about the latest update. Available in digital, print and code format, this new update extends the introductory content on sorting with the advanced quicksort algorithm. Unlike algorithms like insertion sort and bubble sort, the quicksort technique applies a divide & conquer strategy and has an average time complexity of O (n log n). Existing readers can enjoy this new chapter with color illustrations and the latest Swift 3.0 code.

Already had a chance to pre-order a printed book? This new content will be included when we start shipping books later this month.
