Composite

Composite in Swift

Composite is a structural design pattern that allows composing objects into a tree-like structure and work with the it as if it was a singular object.

Composite became a pretty popular solution for the most problems that require building a tree structure. Composite’s great feature is the ability to run methods recursively over the whole tree structure and sum up the results.

Usage of the pattern in Swift

Popularity:

Usage examples: The Composite pattern is pretty common in Swift code. It’s often used to represent hierarchies of user interface components or the code that works with graphs.

Identification: The composite is easy to recognize by behavioral methods taking an instance of the same abstract/interface type into a tree structure.
