Recently @ToddKerpelman and I converted a reference iOS Google Cast app to Swift. Before, I implemented Firebase iOS quickstarts. I created both Objective-C and Swift target at the same time. But I never tried to migrate a full app to Swift before. So I welcomed this challenge.
Blame me being lazy. I didn’t want to do to mundane work of declaring each variable and function in Swift. I decided to take a leap in faith and try a converter tool as a starter. I was going to see how good it can translate. Then I was going to catch build errors and bugs after checking line by line. Finally, I was going through with a linter tool to catch any bad style.
