Keychain Storage is a simple Keychain wrapper written in Swift.
If you ever wanted to save something in Keychain without writing too much code, you are in the right place.

Requirements

• iOS 12.0+
• Xcode 10.2+

Installation

Cocoa Pods

CocoaPods is a dependency manager for Cocoa projects. For usage and installation instructions, visit their website. To integrate Keychain Storage into your Xcode project using CocoaPods, specify it in your Podfile:

pod 'KeychainStorage', '~> 1.3.0'

Carthage

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. To integrate KeychainStorage into your Xcode project using Carthage, specify it in your Cartfile:

github "radude89/KeychainStorage" "1.3.0"

Swift Package Manager

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

Once you have your Swift package set up, you can add KeychainStorage as a dependency by adding it to the dependencies array of your Package.swift.

dependencies: [
    .package(url: "https://github.com/radude89/KeychainStorage.git", from: "1.0.0")
]
