Retrieving the account name from Keychain - swift3

Question

I want to save and retrieve the password and userAccount in keychain. I found a solution in stackoverflow and I use the code there. Save and Load from KeyChain | Swift. But this code only saves and load the password not the accountName. I think I figured out how to save the accountName but I need to figure out how to load it along with the password. Here is the code to save you some time from going into that link.
var userAccount = "AuthenticatedUser"
let accessGroup = "SecurityService"
// Mark: User defined keys for new entry
// Note: add new keys for new secure item and use them in load and save methods
let accountKey = "KeyForAccount"
let passwordKey = "KeyForPassword"
private class func save(service: String, data: String) {
let dataFromString: NSData = data.data(using: String.Encoding(rawValue: String.Encoding.utf8.rawValue), allowLossyConversion: false)! as NSData
//Instantiate a new default keychain query
let keychainQuery: NSMutableDictionary = NSMutableDictionary(objects: [kSecClassGenericPasswordValue, service, userAccount, dataFromString], forKeys: [kSecClassValue, kSecAttrServiceValue as NSCopying, kSecAttrAccountValue as NSCopying, kSecValueDataValue as NSCopying])
//Add new keychain item
let status = SecItemAdd(keychainQuery as CFDictionary, nil)
if status != errSecSuccess { //Always check status
print("Write failed. Attempting update.")
//updatePassword(token: data)
}
}
private class func load(service: String) -> String? {
//Instantiate a new default keychain query
//Tell the query to return a result
//Limit our results to one item
let keychainQuery: NSMutableDictionary = NSMutableDictionary(objects: [kSecClassGenericPasswordValue, service, userAccount, kCFBooleanTrue, kSecMatchLimitOneValue], forKeys: [kSecClassValue, kSecAttrServiceValue as NSCopying, kSecAttrAccountValue as NSCopying, kSecReturnDataValue as NSCopying, kSecMatchLimitValue as NSCopying])
var dataTypeRef: AnyObject?
//Search for the keychain items
let status : OSStatus = SecItemCopyMatching(keychainQuery, &dataTypeRef)
var contentsOfKeychain: String? = nil
if status == errSecSuccess {
if let retrieveData = dataTypeRef as? Data {
contentsOfKeychain = String(data: retrieveData as Data, encoding: String.Encoding(rawValue: String.Encoding.utf8.rawValue))
}
} else {
print("Nothing was retrieved from the keychain. Status code \(status)")
}
print(contentsOfKeychain ?? "none found")
return contentsOfKeychain
}
Complete code is inside the link. Thanks all.

Answer 1

But this code only saves and load the password not the accountName.
The code you show doesn't save or load the password or the account name.
What you have are two functions, one to save a key/value pair, one to load a key's value. It is how you call these two functions that determines what gets saved/loaded.
Somewhere in your code you call save to save the password, you need to call save (using a different key) to save the account name as well. Likewise for load. Your code does define the two keys to use (accountKey & passwordKey).
