These are the complete downloadable code examples for my books, iOS 13 Programming Fundamentals With Swift (http://shop.oreilly.com/product/0636920310068.do) and Programming iOS 13 (http://shop.oreilly.com/product/0636920310075.do).
Examples have been revised for Xcode 11, Swift 5.1, and iOS 13.
If you find these examples helpful and you haven't purchased the books, please consider doing so.
The downloadable code for previous editions has been moved off to subfolders "iOS12bookExamples", "iOS11bookExamples", "iOS10bookExamples", "iOS9bookExamples", "iOS8bookExamples" and "iOS7bookExamples". The code for the earlier editions has been removed.
