Converting Complex Objective-C Macros to Swift Functions

This article explains how to convert complex Objective-C #define macros into Swift functions, addressing the lack of macro support in Swift. It covers simple macro conversion to constants or functions, and provides a detailed example of converting a UIColor-from-hex macro with bitwise operations into a Swift function using generics and proper Swift syntax. The article includes practical tips on organizing Swift code and references Apple documentation and a GitHub example project. It is relevant to IT/TECHNOLOGY as it focuses on software development and code migration between programming languages.
