Actually ComponentKit is built on GCD!

GCD is fantastic—one of my absolute favorites. We're trying to solve a problem one level above that: exposing an API that doesn't require every view developer to know the details of managing GCD queues and updating a UICollectionView.

As for Autolayout, it's very powerful but isn't performant enough for layouts as complex as Facebook's News Feed. We tried it first before developing ComponentKit.

Thanks for explaining. Doing everything top to bottom myself, my mind boggles at an organization where there are multiple "view developers." Nice to have that kind of resources!

Did you try Auto Layout with a flattened view hierarchy? Deeply nested view hierarchies are not really the best way to go if there are performance issues. You can get huge speedups by flattening things. I have a feeling this could even work within the ComponentKit way of doing things.
