It probably toke us the same time to have the project to compile, however we weren’t happy with some of the Xcode migration choices as well as some of our own practices.
A big chunk of work has been done in Objective c, namely nullability modifiers, swift name function conversion, function to class properties.
We have around 20K lines of Swift code in around 180 files.
The project relies on 24 pods 😥 of which none uses Swift. We are currently in the process of reducing our Cocoapods dependencies drastically.
