You love Swift's Codable protocol and use it everywhere, who doesn't! Here is an easy and very light way to store and retrieve -reasonable amount 😅- of Codable objects, in a couple lines of code!

Introducing v2.0

  • Removed the Identifiable protocol in favor of Swift's Identifiable.
  • Increased deployment targets to iOS 13.0, tvOS 13.0, macOS 10.15, and watchOS 6.0.
  • Objects defined as non-final classes can now be used as well.
  • Added new generateSnapshot() and restoreSnapshot(_:) methods to generate and restore a Snapshot object that can be saved (e.g. to iCloud) and restored later.
  • Fixed a bug where objectsCount might run out of sync with the actual count of objects in store.



Let's say you have 2 structs; User and Laptop defined as bellow:

struct User: Codable {
    var id: Int
    var firstName: String
    var lastName: String
    var laptop: Laptop?
struct Laptop: Codable {
    var model: String
    var name: String

Here is how you store them in UserDefaultsStore:

1. Conform to the Identifiable protocol and set the id property

The Identifiable protocol lets UserDefaultsStore knows what is the unique id for each object.

struct User: Codable, Identifiable {
struct Laptop: Codable, Identifiable {
    var id: String { model }

2. Create UserDefaults Stores

let usersStore = UserDefaultsStore<User>(uniqueIdentifier: "users")
let laptopsStore = UserDefaultsStore<Laptop>(uniqueIdentifier: "laptops")

3. Voilà, you're all set!

let macbook = Laptop(model: "A1278", name: "MacBook Pro")
let john = User(id: 1, firstName: "John", lastName: "Appleseed", laptop: macbook)

// Save an object to a store
try! usersStore.save(john)

// Save an array of objects to a store
try! usersStore.save([jane, steve, jessica])

// Get an object from store
let user = store.object(withId: 1)
let laptop = store.object(withId: "A1278")

// Get all objects in a store
let laptops = laptopsStore.allObjects()

// Check if store has an object
print(usersStore.hasObject(withId: 10)) // false

// Iterate over all objects in a store
laptopsStore.forEach { laptop in

// Delete an object from a store
usersStore.delete(withId: 1)

// Delete all objects in a store

// Know how many objects are stored in a store
let usersCount = usersStore.objectsCount

// Create a snapshot
let snapshot = usersStore.generateSnapshot()

// Restore a pre-generated snapshot
try? usersStore.restoreSnapshot(snapshot)

Looking to store a single item only?

Use SingleUserDefaultsStore, it enables storing and retrieving a single value of Int, Double, String, or any Codable type.
