Simple example of using closures
// MARK: LoginViewController
class LoginViewController: UIViewController {
func login(with username: String,
password: String) {
let authenticationSession = AuthenticationSession()
authenticationSession.performLogin(with: username,
password: password,
completion: { userIdentifier in
// Handle the login with userIdentifier
})
}
}
// MARK: AuthenticationSession
class AuthenticationSession {
func performLogin(with username: String,
password: String,
completion: ((String) -> Void)) {
let userIdentifier = "12345" //Service.login(username, password)
completion(userIdentifier)
}
}
