I am setting up my sign up and login page using parse on xcode with swift but i keep getting a fatal error. Can somebody see what im doing wrong? - xcode

Question

this is what i have so far:
import Foundation
import Parse
import UIKit
import Bolts
class SignUpViewController: UIViewController, UITextFieldDelegate {
#IBOutlet weak var statusLabel: UILabel!
#IBOutlet weak var emailTextField: UITextField!
#IBOutlet weak var passwordTextField: UITextField!
#IBOutlet weak var createAccountButton: UIButton!
override func viewDidLoad()
{
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
emailTextField.delegate = self;
passwordTextField.delegate = self;
}
override func didReceiveMemoryWarning()
{
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
#IBAction func createAccountButtonPressed(sender: AnyObject) {
if verifyEmailDomain(self.emailTextField.text)
{
createAccount(self.emailTextField.text, password: self.passwordTextField.text)
}
else
{
//self.statusLabel.text = "Email domain is not valid.";
let alert = UIAlertView()
alert.title = "Invalid Email Domain"
alert.message = "Make sure you entered in your address correctly. If you did, ask your system about using PageMD! Thanks."
alert.addButtonWithTitle("Close")
alert.show()
}
}
func verifyEmailDomain(email: String) -> Bool
{
var isVerifiedDomain = false
let userDomain: String = (email.componentsSeparatedByString("#")).last!
//NSLog(userDomain)
let validDomainsFileLocation = NSBundle.mainBundle().pathForResource("ValidDomains", ofType: "txt")
var validDomainsFileContent = NSString(contentsOfFile: validDomainsFileLocation!, encoding: NSUTF8StringEncoding, error: nil)
// NSLog(validDomainsFileContent! as String)
let validDomains = validDomainsFileContent!.componentsSeparatedByString("\n")
for domain in validDomains
{
NSLog(domain as! NSString as String)
if userDomain == (domain as? NSString)
{
isVerifiedDomain = true
break
}
}
return isVerifiedDomain
}
func createAccount(email: String, password: String)
{
var newUser = PFUser()
newUser.username = email // We want the user to login only with their email.
newUser.email = email
newUser.password = password
newUser.signUpInBackgroundWithBlock { (succeeded: Bool, error: NSError?) -> Void in
if error == nil
{
// Account created successfully!
if succeeded == true
{
self.statusLabel.text = "Account created!"
}
}
else
{
if let errorField = error!.userInfo
{
self.statusLabel.text = (errorField["error"] as! NSString) as String
}
else
{
// No userInfo dictionary present
// Help from http://stackoverflow.com/questions/25381338/nsobject-anyobject-does-not-have-a-member-named-subscript-error-in-xcode
}
}
}
}
func textFieldShouldReturn(textField: UITextField) -> Bool
{
textField.resignFirstResponder()
return true;
}
}
when i run it i receive this in my terminal for xcode:
fatal error: unexpectedly found nil while unwrapping an Optional value
(lldb)
and highlighted in green is:
var validDomainsFileContent = NSString(contentsOfFile: validDomainsFileLocation!, encoding: NSUTF8StringEncoding, error: nil)
what can i do to avoid this error?
I'm trying to create a login that uses the emailVerified feature from parse but I keep receiving this error and cant save the email to the core or send the verification email to the user. What can i do to make this code work and stop the error from coming up?

Answer 1

In that case, the file at validDominsfileContent wasn't found. You need to make sure that the file is included in your Bundle.
To do that, open the Bundle-Resources:
Project > App target > Build Phases > Copy bundle resources
There you save your file. Now it should be found by Swift.
