Flattening an entire view hierarchy into a single layer improves performance, but with UIKit, comes with a hit to maintainability and hierarchy-based reasoning.
With all AsyncDisplayKit nodes, enabling precompositing is as simple as:
SwiftObjective-C
rootNode.shouldRasterizeDescendants = YES;
rootNode.shouldRasterizeDescendants = true
This line will cause the entire node hierarchy from that point on to be rendered into one layer.
