I did the same, porting a huge python script that had grown way too unwieldy to Swift. It undoubtedly saved me time. Your project sounds a lot bigger than mine, 4500 is a lot of compilation errors. If it’s not already split into modules, could be a good time to do it piece by piece. Port one little library at a time.
