how to make a password confirmer swift 3

I have 4 text fields, and 2 of them are password and confirm password. I need to check they are they same or have text in them before proceeding into the login screen. Heres my code:

func registerButtonTapped() {
    var a = false
    var b = false

    if passwordFieldR.text! == confirmFieldR.text! {
        a = true
    } else {
        nonMatchingPasswords.text = "Passwords Do Not Match"
    }

    if(passwordFieldR.text! == "" || confirmFieldR.text! == "") {
        nonMatchingPasswords.text = "Password Field is empty"
    } else {
        b = true    
    }

    if a == true && b == true {
        func registerButtonTwo(_ sender: Any) {
            self.performSegue(withIdentifier: "registertologin", sender: self)
        }
    }
}

The app crashes and gives me this error message in the console:

What is happening and how can I fix this?

Validate password and confirm password

func isValidPassword(passworld: String, confirmPassworld: String) -> Bool{
    if confirmPassworld.lowercased() == passworld.lowercased(){
        return true
    }
    return false
}

The error occurs because target / action methods must be declared on the top level of the class.

You probably mean

func registerButtonTapped() {

    var a = false
    var b = false

    if passwordFieldR.text! == confirmFieldR.text! {
        a = true
    } else {
        nonMatchingPasswords.text = "Passwords Do Not Match"
    }

    if(passwordFieldR.text! == "" || confirmFieldR.text! == "") {
        nonMatchingPasswords.text = "Password Field is empty"
    } else {
        b = true
    }

    if a == true && b == true {
       registerButtonTwo(self)
    }
}

func registerButtonTwo(_ sender: Any) {
     self.performSegue(withIdentifier: "registertologin", sender: self)
}

PS: registerButtonTapped() can be written in a more efficient way

func registerButtonTapped() {

    guard let password = passwordFieldR.text, !password.isEmpty,
        let confirm = confirmFieldR.text, !confirm.isEmpty else {
            nonMatchingPasswords.text = "Password Field is empty"
            return
    }
    guard password == confirm else {
        nonMatchingPasswords.text = "Passwords Do Not Match"
        return
    }
    registerButtonTwo(self)

}

Replace 

func registerButtonTwo(_ sender: Any) {
            self.performSegue(withIdentifier: "registertologin", sender: self)
        }

with just

self.performSegue(withIdentifier: "registertologin", sender: self)

I think It will Be useful for You (You can change 5 number to any Number that you want to be minimum of the password characters)

if  ((passwordFieldR.text?.characters.count)! > 5) {


 if passwordFieldR.text! == confirmFieldR.text! {


    print("registertologin")

 } else {

   print("Password Does Not Match Confirm Password")


 }

 } else {

  print("password Characters should be more Than 5")

  }

It seems like you have a dangling connection from storyboard that you deleted from your code but forgot to do so in the storyboard. Right click on the view (probably the login button) and check for a dead connection.
