Summary

In this chapter, we took a crash course on touch. We looked at the expected uses of the common set of multitouch gestures in iOS, and then learned how to implement them in an app from the storyboard, and purely with code. Then we went back to our app Snippets and added some really useful 3D Touch app icon shortcuts. While doing that, we learned a bit more about the Info.plist file, and got introduced to the App Delegate, and even learned how to clean up some old code to fit with a new feature.

Next, in Chapter 8, Exploring Common iOS Frameworks, we're going to get introduced to some of the more common Apple-provided frameworks, and we will also see how to apply them to our Snippets application. We'll be reviewing some UIKit (which we've been using a lot of!), and getting acquainted with the CoreLocation and Social frameworks.
