As the norm of apps nowadays is actually a scrollView rather a view, the default system of Apple to build a view using .xib and AutoLayout has rather become clunky and low performance. Furthermore, the manual way of building layout has proven to be a problem when it comes to process require fast iteration and less error-prone ( mostly due to communication between designer-developer ).
Inspired by this talk about backend-driven native UIs by John Sundell, I'm trying to recreate a system of my own by following his words : using a collection view in order to allow a block-based view creation, allow for a higher performance and easier to use layout design option.
However I did some improvement of my own, such as abstracting away the view layout logic into a protocol, allowing Views to layout subview in a similar way a collectionView laying out its cells. This allows view component to be nested inside each other, such as StackViewComponent ( allow stacking component ) and ScrollViewComponent ( allow adding views in a scrollView ).
The cells are also current route all the logic ( delegate, datasource ) from the collection cells into the main view controller. Similar component types will need to separate its behavior by tag.
The current state of project is just a proof of concept, rather than a complete implementation.For a more complete layout option, try Render by Alexdrone, Few.swift or Facebook/Yoga
Clone and run the workspace file Example folder.
Further documentation will be added later on, should this library became more mature.
