SimpleKeychain

SimpleKeychain is a Swift package providing a convenient interface for interacting with the iOS Keychain. It is designed to simplify common tasks such as storing and retrieving sensitive data securely.

Features

• Generic Storage: Store and retrieve generic items securely in the Keychain.
• Type-Safe Retrieval: Retrieve stored items with type safety using Swift generics.
• Item Class Types: Support for different item class types, such as generic or internet password.
• Duplicate Item Handling: Automatically handles duplicate items during storage.

Installation

Swift Package Manager

To integrate SimpleKeychain into your Xcode project using Swift Package Manager, add the following dependency to your Package.swift file:

dependencies: [
    .package(url: "https://github.com/yourusername/SimpleKeychain.git", from: "0.1.0")
]

Usage

Initialization

// Initialize SimpleKeychain with optional service and access group parameters
let keychain = SimpleKeychain(service: "com.yourapp.keychain", accessGroup: "your.access.group")

Storing and Retrieving Data

// Store an item
try keychain.set("YourItem", for: "YourKey")

// Retrieve an item
let retrievedItem: String = try keychain.get(key: "YourKey")

Deleting and Clearing

// Delete a specific item
try keychain.delete("YourKey")
// Or alternatively set a nil value
try keychain.set(nil, for: "YourKey")

// Clear all items of a specific class type
try keychain.clear(ofType: .generic)

Error Handling

All operations that interact with the Keychain may throw errors of type SimpleKeychainError. Ensure to handle these errors appropriately in your code.

do {
    // Perform Keychain operation
} catch let error as SimpleKeychainError {
    // Handle the error
    print("Keychain operation failed: \(error.localizedDescription)")
} catch {
    // Handle other errors
    print("An unexpected error occurred: \(error.localizedDescription)")
}
