FavoritesManager

FavoritesManager is a Swift package that provides a simple way to manage a list of favorite items using iCloud. It uses NSUbiquitousKeyValueStore to store and synchronize data across devices.

Installation

Swift Package Manager

You can use Swift Package Manager to install FavoritesManager by adding it to your Package.swift:

dependencies: [
    .package(url: "https://github.com/ezefranca/FavoritesManager.git", from: "1.0.0")
]

Or, add it to your project in Xcode:

• Click on File > Swift Packages > Add Package Dependency
• Enter the URL of the FavoritesManager repository: https://github.com/ezefranca/FavoritesManager.git
• Follow the instructions to complete the installation.

To use NSUbiquitousKeyValueStore, you need to enable iCloud for your app in the Apple Developer Portal and create an App ID with iCloud enabled.

Then, follow these steps:

Go to your project in Xcode.

• Select your target.
• Click on the “Signing & Capabilities” tab.
• Click the “+ Capability” button to add a new capability to your project.
• Search for “iCloud” and select it.
• Select the “Key-value storage” checkbox.
• Enter a unique identifier for your key-value store in the “iCloud Containers” section.
• Save your changes.

After completing these steps, your app should be able to access iCloud key-value storage.

Usage

To use FavoritesManager, you need to create a struct or class that conforms to the Codable and Equatable protocols. You can then use it to save, remove, and retrieve favorite items. Here’s a simple example of how you could use FavoritesManager:

import Foundation
import FavoritesManager

struct Person: Codable, Equatable {
    let name: String
    let age: Int
}

var manager = FavoritesManager<Person>(key: "people")
let person1 = Person(name: "John", age: 25)
let person2 = Person(name: "Mary", age: 30)
let person3 = Person(name: "Alex", age: 35)

Save a favorite element

manager.save(person1)
print(manager.favorites) // [Person(name: "John", age: 25)]

Save another favorite element

manager.save(person2)
print(manager.favorites) // [Person(name: "John", age: 25), Person(name: "Mary", age: 30)]

Try to save a duplicated element

manager.save(person1)
print(manager.favorites) // [Person(name: "John", age: 25), Person(name: "Mary", age: 30)]

Check if an element is favorite

let isFavorite = manager.isFavorite(person1)
print(isFavorite) // true

Get all favorite elements

let favorites = manager.getAll()
print(favorites) // [Person(name: "John", age: 25), Person(name: "Mary", age: 30)]

Remove a favorite element

manager.remove(person1)
print(manager.favorites) // [Person(name: "Mary", age: 30)]

Remove all favorite elements

manager.removeAll()
print(manager.favorites) // []
