Take a look to this example:

Define a structure to hold the credentials as they move around your app in memory:

struct Credentials {
    var username: String
    var password: String
}

Next, define an error enumeration that you can use to communicate keychain access outcomes:

enum KeychainError: Error {
    case noPassword
    case unexpectedPasswordData
    case unhandledError(status: OSStatus)
}

Then, identify the server that your app is working with:

static let server = "www.example.com"

Create an Add Query Using an instance of the credentials structure and the server constant, you can create an add query:

let account = credentials.username
let password = credentials.password.data(using: String.Encoding.utf8)!
var query: [String: Any] = [kSecClass as String: kSecClassInternetPassword,
                            kSecAttrAccount as String: account,
                            kSecAttrServer as String: server,
                            kSecValueData as String: password]

Add the Item With the query complete, you simply feed it to the SecItemAdd(_:_:) function:

let status = SecItemAdd(query as CFDictionary, nil)
guard status == errSecSuccess else { throw KeychainError.unhandledError(status: status) }
