I have worked with lots of codebases using UIKit constraints in code. These were non-trivial apps (200k lines of code). You can create wrappers of your own to simplify things or use libraries like Snapkit. It works and there's no need to use Storyboards.

The bad codebase I'm thinking of was 120 kloc. But I'll take your word for it being possible to do better than that example, one example is merely an anecdote.
