Swift Package: SecureStorage

In this post, we will explore the SecureStorage Swift Package, a powerful tool for managing sensitive data in your applications.

What is SecureStorage?

SecureStorage is a Swift Package that simplifies the process of storing and retrieving sensitive data, such as passwords and tokens, securely. It provides a straightforward API for interacting with the Keychain, making it easy to persist sensitive information across app launches.

Installation

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

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

Then, add SecureStorage to the dependencies of your target:

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

## Use Case: Storing User Credentials

Imagine you want to securely store user credentials, such as a username and password, in your application. With `SecureStorage`, you can easily save and retrieve these values.

```swift
import SwiftUI
import SecureStorage

struct ContentView: View {
    @SecureStorage("username")
    var username: String = ""

    @SecureStorage("password")
    var password: String = ""

    var body: some View {
        VStack {
            TextField("Username", text: $username)
            SecureField("Password", text: $password)

            Button("Save Credentials") {
                // Save the credentials securely
            }
        }
        .padding()
    }
}

Caveats

• Make sure to handle errors when accessing the Keychain.

• Be aware of Keychain's limitations on data size and types.
