Chapter 15. Optimizing Your App

So here we are with an app that is feature complete (for this first release), tested, and debugged. What's left to do? A lazier developer would call it done and just ship the app, but there's still some performance we can squeeze out of our app, and detail work to be done.

To do this, we're going to look at the features in Xcode that help us optimize our app's performance. There are also tools to help us optimize the amount of space the app takes up on the user's device. In this chapter, we're going to cover:

The Instruments performance analysis toolset
Asset slicing using asset catalogs in Xcode
Bitcode compiling
On-demand resources
