Chapter 20. Using Fastlaneâs Tools
Fastlane contains a number of useful tools for automating development. In this chapter, weâll be taking a close look at the most important components in the Fastlane collection, and how you can use them.

In all cases, weâll assume that youâve already set up your project for use with Fastlane, by following the steps in âSetting Up a Projectâ.
