There are many dependancies that require some kind of reimplementation, it's a pain.
I have made things easier (in the long run) with my last game. I wrote it all in c++ with all dependancies under my control. I was thinking >20 years ahead for that one.
Xcode, I use Xcode for the most part and visual studio for the Steam version.
It took way longer to create than if I was using Unity, but its a great solution for a small and performant end product. I was able to get Kanso down below 100MB and will run on a total potato. Something I highly doubt I could do in Unity without some serious effort.
