ObjectMapper is a Swift framework that converts model objects (classes and structs) to and from JSON using the Mappable protocol and the <- operator. AlamofireObjectMapper extends it with Alamofire response serialization for mapping API responses directly to objects.

Use cases

• map json to swift model objects
• serialize swift structs to json
• parse api responses into models
• handle nested json objects in swift
• apply custom transformations during json mapping
• deserialize json strings into classes

When to choose

• you need bidirectional JSON mapping for Swift classes and structs
• you use Alamofire and want automatic response-to-model mapping
• you need nested object, array, and dictionary mapping with custom transforms

When to avoid

• you can use Swift's built-in Codable protocol instead
• you need XML or formats other than JSON
• you want a library under heavy active development
