Requirements

• iOS 18.0+

Installation

Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code, integrated into the swift compiler.

To add KeychainStorage as a dependency, include it in the dependencies array of your Package.swift file:

dependencies: [
    .package(url: "https://github.com/radude89/KeychainStorage.git", from: "2.0.2")

For manual installation, simply drag and drop the following files into your project from the KeychainStorage directory:

• KeychainQueryFactory.swift
• KeychainStorage.swift
• KeyValueStorage.swift

Examples

Make sure to explore the small app included in the example project found at Example/KeychainStorageExample.xcworkspace. Build and run the project to see it in action.

Retrieving a Value from the Keychain

import KeychainStorage

let storage = KeychainStorage(service: "com.test.service")
