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, NSData and objects that implement NSCoding.
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.stringForKey("myKey")Remove a string value from keychain:
let removeSuccessful: Bool = KeychainWrapper.removeObjectForKey("myKey")v1.0.5 has been tagged in master
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
In addition to adding Cocoapods support, there is a known issue with Swift keychain access causing it to fail. I don't know the full extent of the issue, but one "work around" is to turn off Swift compile optimization for release and the problem goes away:

This is not an ideal solution, so as recommended, I've added an objective c wrapper/helper for the keychain data retrieval. This allows the KeychainWrapper to work as expected with Swift compile optimizations enabled.
======
v1.0.2 has been updated for Xcode 6.1
Currently this is not a static library, as static libraries do not support swift code when I created this. I intend to update this project to a static library and make it a cocoapod once supported.
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.
