Overview of this book

The iOS development environment has significantly matured, and with Apple users spending more money in the App Store, there are plenty of development opportunities for professional iOS developers. However, the journey to mastering iOS development and the new features of iOS 12 is not straightforward. This book will help you make that transition smoothly and easily. With the help of Swift 4.2, you’ll not only learn how to program for iOS 12, but also how to write efficient, readable, and maintainable Swift code that maintains industry best practices. Mastering iOS 12 Programming will help you build real-world applications and reflect the real-world development flow. You will also find a mix of thorough background information and practical examples, teaching you how to start implementing your newly gained knowledge. By the end of this book, you will have got to grips with building iOS applications that harness advanced techniques and make best use of the latest and greatest features available in iOS 12.

Combining CoreML and computer vision


When you're developing an app that works with photos or live camera footage, there are several things you might like to do using computer vision. For instance, it could be desirable to detect faces in an image. Or, maybe you would want to identify certain rectangular areas of photographs, such as traffic signs. You could also be looking for something more sophisticated, like detecting the dominant object in a picture.

To work with computer vision in your apps, Apple has created the Vision framework. You can combine Vision and CoreML to perform some pretty sophisticated image recognition. Before you implement a sample app that uses dominant object recognition, let's take a quick look at the Vision framework, so you have an idea of what it's capable of and when you might like to use it.

Understanding the Vision framework

The Vision framework is capable of many different tasks that revolve around computer vision. It is built upon several powerful deep learning...
