CocoaPods also functions as a discovery engine. The experience is very unpolished, but it will surface the code that other people have written with the explicit intention of offering as a library to other people. Which is a subset of "code other people have released on github", obviously.
I'm a skeptic too. I've played with it, but requiring a couple dozen additional ruby gems and editing my Xcode project files underneath me creeps me out, so I won't use it for personal or client work.
I've been hired into existing projects that used it though, and it works fine as long as you manage it as a glorified drag-n-drop. You can blow yourself up if you trust it like a vendor-approved auto-upgrade mechanism. That's as much a factor of the ecosystem as the tool, and I hope Pods and Pod authors will coalesce around a level of maturity that's useful in shipping code environments.
