Parse Swift Email Password Reset

Rather than using Alert PopUP, I was attempting to simply have a separate view controller to have email entry box with submit button to send reset email.

import UIKit

class ForgotPasswordViewController: UIViewController {

@IBOutlet weak var email: UITextField!


@IBAction func submitEmail(sender: AnyObject) {


PFUser.requestPasswordResetForEmailInBackground(email.text)
}

This code is "missing argument for parameter 'target' call", not sure how to implement this.

The password reset uses a closure, This is an example from a previous project I was hired to make.

        var initialEmail = emailInput.text
        var email = initialEmail.lowercaseString
        var finalEmail = email.stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceCharacterSet())
        PFUser.requestPasswordResetForEmailInBackground(finalEmail) { (success: Bool, error: NSError!) -> Void in
            if (error == nil) {
                var success = UIAlertController(title: "Success", message: "Success! Check your email!", preferredStyle: .Alert)
                var okButton = UIAlertAction(title: "OK", style: .Default, handler: nil)
                success.addAction(okButton)
                dispatch_async(dispatch_get_main_queue(), { () -> Void in
                    self.presentViewController(success, animated: false, completion: nil)
                })
            }else {
                var errormessage = error.userInfo!["error"] as NSString
                var error = UIAlertController(title: "Cannot complete request", message: errormessage, preferredStyle: .Alert)
                var okButton = UIAlertAction(title: "OK", style: .Default, handler: nil)
                error.addAction(okButton)
                dispatch_async(dispatch_get_main_queue(), { () -> Void in
                    self.presentViewController(error, animated: false, completion: nil)
                })

            }
        }
    }

I don't know if Parse updated this function recently but apparently your code doesn't work anymore.

The documentation doesn't mention the closure now and when trying to run your code I get a complaint about the arguments:

"Cannot invoke 'requestPasswordResetForEmailInBackground' with an argument list of type '(String ()-> Bool )'".
