UserDefaults.swift

import Foundation

    let name: String
    let isActive: Bool
}

extension UserDefaults {
    private struct Keys {
        static let awesomeObject = "awesomeObject"
        static let awesomeArray = "awesomeArray"
    }

    class var awesomeObject: MyStruct? {
        get {
            guard let data = standard.value(forKey: Keys.awesomeObject) as? Data,
                let object = try? JSONDecoder().decode(MyStruct.self, from: data) as MyStruct else { return nil }
            return object
        }

        set {

    class var awesomeArray: [MyStruct] {

                let array = try? JSONDecoder().decode(Array.self, from: data) as [MyStruct] else { return [] }
            return array
        }

        set {

                UserDefaults.standard.set(encoded, forKey: Keys.awesomeArray)
            }
        }
    }
}

// Usage
let xxx = MyStruct(name: "XXX", isActive: true)
let yyy = MyStruct(name: "YYY", isActive: false)

UserDefaults.awesomeObject = xxx
dump(UserDefaults.awesomeObject)

let myArray = [xxx, yyy]
UserDefaults.awesomeArray = myArray
dump(UserDefaults.awesomeArray)
