This Keychain Swift API library is a wrapper of iOS C Keychain Framework. It allows easily and securely storing sensitive data in secure keychain store in Swift projects. Interfacing with the original C keychain API is combersome from Swift, and is prone to errors which lead to security vulnerabilities. This library is written according to the best security coding practices and guidelines.


Import the KeychainSwiftAPI import KeychainSwiftAPI

Create a query object:
let q = Keychain.Query()
Populate the query object with data. Query properties correspond to attribute keys of the C Keychain API, protery values correspond to attribute values of the C Keychain API. q.kSecClass = Keychain.Query.KSecClassValue.kSecClassGenericPassword q.kSecAttrDescription = "A password from my website" q.kSecAttrGeneric = "VerySecurePassword".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false) q.kSecAttrAccount = "admin" q.kSecReturnData = true q.kSecReturnAttributes = true q.kSecReturnRef = true q.kSecReturnPersistentRef = true Call Keychain.secItemAdd, which returns a pair of success code and result object. let r = Keychain.secItemAdd(query: q) Success code is wrapped in Keychain.ResultCode enum for convenience. if (r.status == Keychain.ResultCode.errSecSuccess) { println("Password saved. Returned object: (r.result)") } else { println("Error saving password: (r.status.description)") } r.result contains the object that was retured by the C SecItemAdd underlying function call.


iOS 8.0 or above You have to use cocoapod compiled from the Swift branch, since the master branch of cocoapods still does not fully support Swift. See: Using Cocoapods Unreleased Features
