Automatic deployment is the ability to create a beta or an App Store version of an app with just one click or command. It is of great benefit to be able to ship a version without all the hassle of provisioning profiles and code signing (often referred to as code signing hell). Felix Krause, a developer, started a project named fastlane.tools to make deployment on iOS as easy as running a command in Terminal.app. We will use fastlane in this section to set up the automatic deployment for our to-do app.
To run the commands in this section, you need a paid developer account.
