How to use User Defaults with Property Wrappers

UserDefaultsPropertyWrapper.swift

import Foundation

@propertyWrapper
struct UserDefaultsWrapper<Value: Codable> {
    let key: String
    let defaultValue: Value
    let userDefaults = UserDefaults(suiteName: Constants.kGroupIdentifier)

    var wrappedValue: Value {
        get {
            let data = userDefaults?.data(forKey: key)
            let value = data.flatMap { try? JSONDecoder().decode(Value.self, from: $0) }
            return value ?? defaultValue
        }

        set {
            let data = try? JSONEncoder().encode(newValue)
            userDefaults?.set(data, forKey: key)
            userDefaults?.synchronize()
        }
    }
}

struct Task: Codable, Equatable {
    let id: UUID
    var title: String
    var isDone: Bool
}

final class DataProvider {
  @UserDefaultsWrapper(key: Constants.kTaskDefaultKey, defaultValue: defaultTasks)
    var tasks: [Task] 
}
