Perform segue after Login successful in Storyboards

Question

I have 2 UITextFields, one of them for Login and the another for the Password.

Only if the Login is \"succesful\", I want to perform the Segue

Answer 1

Swift 4 You can still link UIButton to the View Controller and create a Segue. If your login is successful then invoke self.performSegue within your closure. Something like this...

@IBAction func loginButtonPressed(_ sender: AnyObject) {
        authenticateUser(email: email.text!, password: password.text!)
}

func authenticateUser(email: String, password: String){
        # Building your loginUrl goes here

        Alamofire.request(loginUrl!,
                          method: .post,
                          parameters: nil,
                          encoding: JSONEncoding.default,
                          headers: headers)
            .validate()
            .responseJSON { (response:DataResponse) in
                switch(response.result) {
                case .success(_):

                    let apiResponse : JSON = JSON(response.result.value!)

                    print("Now Performing Segue on IBAction Pressed")
                    self.performSegue(withIdentifier: "goToDashboard", sender: self)
                   break

                case .failure(_):
                    print(response.result.error)
                    break
                }
            }
    }
