Large Titles For Navigation Bars In iOS 11

Handling Keyboard Shortcuts In iOS

The keyboard is an enormously important piece of hardware. The keyboard lets us increase efficiency while using an app by typing faster. It also gives iOS apps the ability to support shortcuts, which increases productivity even more. Common tasks for apps would be greatly benefited by allowing shortcuts, especially on an iPad, by allowing the user to keep their hands on the keyboard.

Enabling Siri Integration With SiriKit

SiriKit was created for developers in iOS 10. However, there were, and still are, a limited number of intent domains with which you can integrate an app. An intent domain is simply a category of app that can take advantage of Siri.
