A Swift library providing property wrappers like @LossyArray, @LossyDictionary, and @DefaultCodable that simplify Codable JSON decoding. It eliminates boilerplate custom Decodable initializers by handling nulls, invalid elements, and default values declaratively.

Use cases

• decode json arrays filtering out null or invalid elements
• provide default values for missing json fields in swift structs
• avoid writing custom init(from decoder:) boilerplate
• tolerate messy api responses with null values
• decode dictionaries while dropping invalid key-value pairs

When to choose

• your swift app consumes json apis with inconsistent or null data
• you want declarative, wrapper-based Codable customization instead of manual initializers
• you use Swift 5.1+ with Swift Package Manager

When to avoid

• you need strict decoding that fails on any malformed data
• your project targets Swift versions before 5.1
• you need wrappers for formats beyond what the library provides and don't want to write custom strategies
