SwiftKeychainWrapper

A simple static wrapper for the iOS Keychain to allow you to use it in a similar fashion to user defaults. Written in Swift.

Supports adding and retrieving Strings, Data and objects that implement NSCoding.

Usage

Add a string value to keychain:

let saveSuccessful: Bool = KeychainWrapper.setString("Some String", forKey: "myKey")

Retrieve a string value from keychain:

let retrievedString: String? = KeychainWrapper.string(forKey: "myKey")

Remove a string value from keychain:

let removeSuccessful: Bool = KeychainWrapper.removeObject(forKey: "myKey")

Release Notes

v1.0.11 Update for Swift 2.0

v1.0.10 Update License info. Merged Pull Request with Carthage support.

v1.0.8 Update for Swift 1.2

v1.0.7 Determined that once provisioned correctly for access groups, using KeychainWrapper on the simulator with access groups works. So I removed the simulator related check and unit tests previously added.

v1.0.6 Support for Access Groups SwiftKeychainWrapperExample has been updated to show usage with an Access Group: https://github.com/jrendel/SwiftKeychainWrapperExample

Access Groups do not work on the simulator. Apps that are built for the simulator aren't signed, so there's no keychain access group for the simulator to check. This means that all apps can see all keychain items when run on the simulator. Attempting to set an access group will result in a failure when attempting to Add or Update keychain items. Because of this, the Keychain Wrapper detects if it is being using on a simulator and will not set an access group property if one is set. This allows the Keychain Wrapper to still be used on the simulator for development of your app. To properly test Keychain Access Groups, you will need to test on a device.

v1.0.5 This version converts the project to a proper Swift Framework and adds a podspec file to be compatible with the latest CocoaPods pre-release, which now supports Swift.

To see an example of usage with CocoaPods, I've created the repo SwiftKeychainWrapperExample: https://github.com/jrendel/SwiftKeychainWrapperExample

v1.0.2 Updated for Xcode 6.1

======

I've been using an Objective-C based wrapper in my own projects for the past couple years. The original library I wrote for myself was based on the following tutorial:

This is a rewrite of that code in Swift.
