I (have to) write C++ professionally. With that constraint, it's easier for me to work in Obj-C because its runtime is so thin and it's generally obvious how it interoperates with C/C++.

I'll take Obj-C over Swift any day. With Swift I feel like I have one arm tied behind my back and I'm constantly wrestling with it in order to do what I want.

Like the person you replied to, I vastly prefer ObjC, I find the compiler pedantry in Swift to be annoying and to slow me down. ObjC is very fast to write and to iterate on, particularly in my style where everything that's an object gets typed as `id` so trying new ideas just means swapping out implementations.
