How do the Objective-C patterns we already know translate into Swift?

Patterns are your go-to code chunks; the things you know exactly how to do in Objective-C because you’ve framed code like it in all of your projects. Swift syntax seems to come pretty easy to iOS developers but we still need a lot of exploration to find the best reimplementations our favorite patterns in Swift.

This is part of that exploration, listing patterns I’ve found while working in Swift and that others have shared elsewhere.

“That thing is Swift” is a listing of examples that shows object oriented design patterns implemented in Swift programming language.

Learn the basics of cool image filtering effects with Core Image and Swift.

Core Image is a powerful framework that lets you easily apply filters to images. You can get all kinds of effects, such as modifying the vibrance, hue, or exposure. It can use either the CPU or GPU to process the image data and is very fast — fast enough to do real-time processing of video frames!

In this tutorial, you will get hands-on experience playing around with Core Image. You’ll apply a few different filters, and you’ll see how easy it is to apply cool effects to images in real time!
