Parsing

Lesson in the iOS Roadmap · Stage 20: JSON / XML

Last updated 14 September 2026

What is Parsing?

Parsing JSON in Swift is done using Codable and JSONDecoder, which automatically decode JSON data into Swift structs and classes. XMLParser provides a SAX-style parser for processing XML documents event by event. Correct parsing handles optional fields, nested structures, and type mismatches cleanly.
