Only use the numbered form when the parameter names add no further information to the closure (e.g. For example: Making the constants static allow them to be referred to without needing instances of the type. For example returning the area of a Circle instance is well suited to be a getter, but converting a Circle to a CGPath is better as a "to" function or an init() extension on CGPath. Inside a single source file feel free to break down a definition into whatever extensions you feel best organise the code in question. Best practices for software development with Swift.
