Getting started with result builders in Swift

Result builders, previously known as function builders, are a feature in Swift since version 5.4 that allows users to create more declarative code, similar to SwiftUI's syntax. They enable developers to construct blocks of code that can contain various components like strings, conditionals, and arrays, without relying on cumbersome syntax like commas. Result builders offer several functions, including buildBlock for basic block building, buildOptional for optional conditions, buildEither for conditional branching, buildArray for handling arrays, and buildExpression to accept different types of elements in a block. This functionality simplifies code readability and maintenance, making it easier to create flexible and clean code structures. The article demonstrates how to implement result builders in Swift, providing examples such as creating a breakfast menu that adjusts based on conditions, and highlights the ability to use result builders across different platforms, including Linux.
