Core Image is a powerful framework offering image processing and analysis for both iOS and OS X. It offers Swift developers a simple API to a wide range of image based effects.
Core Image for Swift is a comprehensive guide to Core Image for iOS Swift developers. It covers all areas of working with Core Image for processing still images
The chapters are:
Introducing Core Image
Core Image Filters in Detail A detailed look at Core Image filters with descriptions of their categories and examples of filter use.
Displaying Filtered Images Looks at different approaches for displaying Core Image output and covers UIImageView, using OpenGL with GLKView and using Metal with MTKView.
Convolution Filters Looks in detail at convolution filters and their effects.
Custom Composite Filters Looks at creating new filters with composites of existing built-in filters
Custom Filters with Core Image Kernel Looks at writing filters from scratch with Core Image Kernel Language
Color Kernels A detailed look at CIColorKernel
Warp Kernels A detailed look at CIWarpKernel
General Kernels A detailed look at CIKernel
Advanced Kernels Discusses advanced kernels for creating fluid dynamic and reaction diffusion systems
Custom Filters with Metal Discusses wrapping Metal compute shaders in a Core Image filter to create effects impossible with CIKernels
ModelIO Based GeneratorsDiscusses using ModelIO’s texture generation tools to create unique imagery such as procedural skies and smooth, color noise for use with Core Image
Working with vImageDiscusses using Accelerate / vImage in conjunction with Core Image to implement histogram and morphology operations which aren't included as part of Core Image.
All chapters are accompanied by fully documented open source Swift projects.

Core Image for Swift is a fantastic book that shows how core image filters can be used, as well as how to write your own filters. Lots of source code is provided. The last time I looked at this subject, it was with Objective-C and there was no way to write your own filters. Now there is and you can use it from Swift. This book provides the best information available with many examples on how to use this amazing technology.
Fabulous! Top shelf book. You can not go wrong purchasing this book. The only request I would make of the author would be to add some sort of version number right below the “First Edition, 2016” statement on the first page.
I recently bought this book. The content seems excellent thus far. However, it does not read well on a phone.
I can either read it in a view that displays two pages at a time, where the content is too small to see, or I can read it in a view that scrolls infinitely, which messes up the code sample formatting, making them impossible to read.
