Swift enums: An overview with examples
Blog post from LogRocket
Swift enumerations, or enums, provide a type-safe way to work with a group of related values, allowing more than two possible outcomes, unlike simple boolean conditions. These enums are particularly useful in switch statements, as Swift ensures all cases are covered, offering a robust way to handle multiple options, akin to a thermostat with settings like low, medium, and high. Enums in Swift differ from those in languages like TypeScript and Objective-C as they do not have default integer values, and they can hold raw values or associated values to represent more complex data. The tutorial explores various aspects of Swift enums, including syntax, the use of CaseIterable for accessing all enum cases, and the creation of methods and computed properties within enums to enhance code functionality. Additionally, it highlights how enums can simplify code by replacing traditional functions with computed properties, offering a streamlined approach to managing complex data structures within Swift.
