Fastlane: from 0 to hero

When we are an iOS developer, there are a lot of repetitive and tedious tasks to release our apps. But doing these same boring things over and over again is just madness.

During this classroom we saw how we can automate all these boring and repetitive tasks with fastlane. This classroom was a part of Frenchkit 2017.

All the resources of this classroom are available on github: https://github.com/FrenchKit/FastlaneClassroom
