I couldn't fix a lot of UI problems because when trying to trace what was happening through this system of actions and states I could only find when these bugs occurred when stepping between lines of machine code.

I can't offer a fair point of view because I don't think the project I was working on made proper use of ReSwift. It was very difficult to follow the flow of data and understand why certain things wouldn't work.

What you're describing doesn't really make any sense... the whole point of these frameworks is to make your application more predictable. If your layout isn't right for a particular state, you can rewind back to that exact state again and again. It sounds like you were using ReSwift wrong, to be honest. There's not a lot of magic going on in it that would make it hard to debug.
