CodableDefaults

Micro library for UserDefaults with Codable.

Requirements

CodableDefaults is written Swift 4.

Usage

CodableDefaults provides easy to use, and type safety. It supports Codable types in Swift standard library and Foundation.

let userID = DefaultStore<String>(forKey: "user ID")

userID.set("your ID") // sets to the UserDefaults.standard
userID.set(10) // ❗️compile error

userID.get() // -> "your ID"

Custom Type

Just conform to the Codable:

struct User: Codable {
    var name: String
    var following: [User]
}

then:

let friend = User(name: "Friend", following: [])
let you = User(name: "You", following: [friend])

let user = DefaultStore<User>(forKey: "user")

user.set(you)

user.get() // -> User(name: "You", following: [friend])

Initial value

Use initializer wrapping register(defaults:).

let shouldShowThumbnail = DefaultStore<Bool>(forKey: “shouldShowThumbnail”, defaultValue: true)

shouldShowThumbnail.get() // -> true

With specified suite name

Init with UserDefaults instance.

let defaults = UserDefaults(suiteName: “domain name”)

let numbers = DefaultStore<[Int]>(forKey: “numbers”, userDefaults: defaults)
