In this episode, we show you how to migrate a project and its dependencies to Swift 4, step by step.

We start with an overview of the dependencies between the modules and, to avoid issues during the migration process, we migrate each module independently, while making sure that all tests are passing at every step and that we end up with no build warnings.

Beware that, although Xcode's migration tool helps a lot, it has limitations, so it’s essential to come up with a good migration strategy as we discuss in the video.
