Swift Package: iCloudStorage

In this post, we will explore the iCloudStorage Swift Package, a powerful tool for managing iCloud key-value storage in your applications.

What is iCloudStorage?

iCloudStorage is a Swift Package that simplifies the process of storing and retrieving key-value pairs in iCloud. It provides a straightforward API for interacting with iCloud's key-value storage, making it easy to persist user preferences and app state across devices.

Installation

To install the iCloudStorage package, you can use the Swift Package Manager. Add the following line to your Package.swift file:

.package(url: "https://github.com/0xWDG/iCloudStorage", branch: "main")

Then, add iCloudStorage to the dependencies of your target:

.target(
    name: "YourApp",
    dependencies: ["iCloudStorage"]
)

Use Case: Storing User Preferences

Imagine you want to store user preferences, such as a theme selection or a user ID, across app launches. With iCloudStorage, you can easily save and retrieve these values.

import SwiftUI
import iCloudStorage

struct ContentView: View {
    @iCloudStorage("key")
    var value: String = "default"

    var body: some View {
        VStack {
            Text(value)

            Button("Change value") {
                value = "Hello there at \(Date())"
            }
        }
        .task {
            value = "Hello there"
        }
        .padding()
    }
}

Caveats
