JSON

JSON is a simple, type-safe JSON type implemented in pure Swift. It's intended to be lightweight and ergonomic. Most especially, it can be used in model value types that need to be sendable.

Usage

let json: JSON = [
    "one": 2,
    "two_text": "two",
    "pi": 3.14,
    "yes": true,
    "null": nil,
    "object": [
        "three": 3,
        "four_text": "four",
        "null": nil,
        "inner_array": [
            "index_0",
            false,
            4.20,
        ] as [Any?],
    ] as [String: Any?],
]

json["one"].integerValue // 2
json["object"]["four_text"].stringValue // "four"

Swift nil maps to JSON null in literals and subscript assignments:

var object: JSON = ["name": "Blob"]
object["deleted_at"] = nil as JSON? // stores JSON.null
object.removeValue(forKey: "name") // removes the key

Missing keys return nil and are distinct from explicit JSON null.

Installation

Swift Package Manager

To use JSON with the Swift Package Manager, add a dependency to your Package.swift file:

let package = Package(
   dependencies: [
       .package(
           url: "https://github.com/shareup/json-apple.git", 
           from: "1.4.0"
       )
   ]
)
