Codextended is a lightweight Swift library of extensions that augments the built-in Codable API with type inference-powered conveniences. It reduces boilerplate for encoding and decoding values, such as one-liner encode/decode calls and easy key-level customization.

Use cases

• decode into swift types with less boilerplate
• encode swift structs to in one line
• provide default values for missing keys when decoding
• transform values during decoding
• simplify custom codable implementations
• avoid verbose JSONEncoder/JSONDecoder setup

When to choose

• you use Swift's Codable and want terser, type-inferred encode/decode calls
• you need lightweight key-level customization without a full serialization framework
• you want a zero-dependency extension layer over Codable on macOS or Linux

When to avoid

• you need serialization formats beyond what Codable supports
• you want a full-featured JSON mapping framework with heavy customization
• you need a library with frequent updates and active maintenance
