A Swift library for encoding and decoding XML using Codable protocols.
XMLCoder is a Swift library that implements XMLEncoder and XMLDecoder, allowing developers to serialize and deserialize XML data using Swift's native Codable protocols. It solves the problem of cumbersome XML parsing by providing a type-safe, declarative approach similar to JSON handling with JSONEncoder/JSONDecoder.
Swift developers working with XML data on Apple platforms (iOS, macOS, tvOS, watchOS), Linux, or Windows, particularly those building server-side applications with Vapor or using Combine for reactive programming.
Developers choose XMLCoder for its deep integration with Swift's Codable ecosystem, advanced features like dynamic node coding and property wrappers, and strong adherence to XML standards, making it the most comprehensive XML parsing solution for Swift.

Leverages Swift's native Codable protocols, making XML parsing as straightforward as JSON with JSONEncoder/JSONDecoder, reducing boilerplate and ensuring compile-time type safety, as shown in the basic example.
Handles complex XML structures like namespaces (via shouldProcessNamespaces), choice elements (with XMLChoiceCodingKey), and dynamic node coding, enabling precise control over attribute/element mapping.
Uses property wrappers (@Attribute, @Element) for concise syntax and integrates with Combine (TopLevelDecoder/TopLevelEncoder) for reactive programming, detailed in the advanced features sections.
Supports all Apple platforms plus Linux and Windows, with clear installation via Swift Package Manager, CocoaPods, and Carthage, as outlined in the requirements and installation instructions.
The Codable abstraction can be slower and more memory-intensive than event-driven parsers for large XML files, as it decodes entire documents into Swift objects, which may not scale well for high-volume data.
Advanced features like dynamic node coding or choice elements require manual implementation of protocols and custom coding keys, increasing boilerplate and learning curve for non-standard XML formats.
Tied to Swift's toolchain and versions, with noted issues like crashes in specific Xcode releases (e.g., 11.2.0), which can impact stability and limit use in mixed-language projects.
