+let keychainWrapper = KeychainWrapper(service: "myApp")
+
+// store password <-> username mapping for service "myApp"
+keychainWrapper["username"] = "secretPassword"
+
+// retrieve password for username
+let password = keychainWrapper["username"]
+
+// delete password entry for username in service "myApp"
+keychainWrapper["username"] = nil
