iOS 11 unleashed a whole range of powerful new tools for you to build intelligent apps, and this book helps you get started with them as quickly as possible: Core ML, Vision, ARKit, and more!

Machine Learning

Take advantage of Core ML to deliver intelligent new apps that can proactively assist your users.


Learn how to augment reality with slick interactive graphics thanks to Apple's new ARKit framework.

Drag & Drop

Let users move data freely inside your app and others too using powerful new multi-touch gestures.


NFC reading, PDFView, Vision, MusicKit, the new iOS 11 design language, and more!


Practical iOS 11 includes seven all-new projects that teach all the major changes introduced in iOS 11, plus technique projects that deep-dive into smaller features.

Project 1: Trade my Tesla

Learn to build your own Core ML model from scratch, then teach iOS how to evaluate the trade-in price of cars using machine learning.

Project 2: Sightspotter

Learn how ARKit can place virtual objects in a real environment, then add Core Location to help tourists find their way around a city.

Project 3: Going Postal

Create a fun postcard app that blends images, text, and colors, all powered by iOS 11's incredible new drag and drop APIs.

Project 4: Swift Sampler

See how easy it is to render PDFs using watermarks and interactive thumbnails, all using the new PDFKit framework.

Project 5: Picture Protector

Face detection APIs got a real boost in iOS 11, so we use them to build an app that detects faces in photos and lets users tap to blur them.

Project 6: Name that Tune

MusicKit lets you integrate Apple Music in your app, and in this project we use it build a fast-paced two-player charts game.

Project 7: Video X-Ray

Build an app that record video while the Vision framework silently detects objects in the scene – finally, searchable videos!

Bonus: Techniques

Master Core NFC, depth-mapping photos, the new iOS 11 look and feel, advanced drag and drop, and face feature detection.

Along the way you'll learn:

  • What's new in Swift 4 and how you can start using the new features today.
  • How to use Core ML and the Vision framework to leverage machine learning in your own apps.
  • The all-new PDFKit framework, delivering fast and efficient PDF rendering on iOS.
  • How to integrate drag and drop into your apps, both using built-in controls and custom controls.
  • Building a complete game from scratch using ARKit's augmented reality technology.
  • Taking advantage of the new MusicKit APIs to work with Apple Music.
  • Reading and acting on NFC tags using Core NFC.
  • Using the new depth-mapping APIs exposed through the iPhone 7 Plus camera.
  • Updating your app for the new iOS 11 look and feel.
  • And more – iOS 11 is packed with new features to learn!

If you want to take advantage of all the incredible new functionality provided in iOS 11, there's no faster way than Practical iOS 11.
