Getting started with RegexBuilder on Swift
Blog post from LogRocket
Swift's RegexBuilder, introduced in version 5.7, provides a more readable and simplified approach to creating regular expressions compared to the traditional cryptic syntax. The article details setting up a Swift Playground in Xcode, illustrating how RegexBuilder components such as CharacterClass, Currency, and Date can be utilized to construct clear and maintainable regular expressions. It contrasts the old Regex API with RegexBuilder, showcasing how quantifiers, choices, and component captures are improved for clarity and ease of use. Practical examples are provided, including parsing text to extract job roles, names, payment amounts, and dates, highlighting RegexBuilder's ability to convert matched text into usable data types like integers and dates. The article concludes by emphasizing the benefits of RegexBuilder in making regular expressions more understandable while noting that the tutorial only touches on the broader capabilities of this API, with further learning available through documentation and additional features like TryCapture.
