What are the Objective-C application repositories with good code structure and patterns?

Question

Objective-C

I read the article OOP Patterns in Examples for iOS and I wanted to look at examples of the implementation of patterns, and competent design in working projects. I have already looked at many examples from the Apple website, but there is some kind of "mess" everywhere.
And on the github, mostly either libraries, or far from everything is written according to the recommendations of the "Gang of 4x". It is desirable, of course, if it were the code of a client-server application. There are no such problems for C++, as far as I understand, but what about Objective-C?

The books often have a repository on github, you can see it there. There are also cookbooks, there are ready-made solutions for a bunch of problems.
If you want to delve into patterns, look for some advanced book, they are just doing what they are trying not just to do, but to do it right and readable, they show tricks that are not used in tutorials from the "if only it works" series.
