Installation

Swift Package Manager

Add the dependency in your Package.swift file:

let package = Package(
    name: "myproject",
    dependencies: [
        .package(url: "git@github.com:DanboDuan/Codable.git", .upToNextMajor(from: "1.0.0")),
    ],
    targets: [
        .target(
            name: "myproject",
            dependencies: ["Codable"]),
        ]
)

Usage

see Example code

• Supprt basic type, Int64, Bool, Double
• Support basic collection, String, Array, Set, Dictionary
• Support custom type extended to Codable & Equatable & DefaultValue

import Codable

struct Car: Codable, Equatable, DefaultValue {
    @Default<Empty>
    public var name: String

    @Default<EmptyValue>
    public var age: Int64

    public init() {}

    public static func == (left: Self, right: Self) -> Bool {
        return left.name == right.name
    }
}

struct Pet: Codable, Equatable, DefaultValue {
    @Default<Empty>
    public var name: String

    @Default<Int64>
    public var age: Int64

    public init() {}

    public static func == (left: Self, right: Self) -> Bool {
        return left.name == right.name
    }
}

    @Default<Empty>
    public var name: String

    @Default<EmptyDictionary>
    public var cars: [String: Car]
