Replace Magic Strings with Enumerations in Swift

This article explains how to eliminate 'magic strings' in Swift code by using enumerations with raw string values. The author shares a practical example of replacing hard-coded segue identifiers in prepareForSegue with a SegueIdentifier enum, improving code maintainability and type safety. It covers defining enums, using toRaw() and fromRaw() methods, and provides cleaner alternatives for switch statements. Ideal for iOS developers looking to adopt best practices in Swift programming.
