Answer 1

Before you try any code, make sure your password is at least 6 characters. Print the error if is possible, I print the error on each function, sign up and sign in.

@IBAction func signUp(_ sender: Any) {

Auth.auth().createUser(withEmail: self.usernameTextField.text!, password: self.passwordTextField.text!) {(user, error) in
    if user != nil {
        print("User Has SignUp")
    }
    if error != nil {
        print(":(",error)
    }
}
   Auth.auth().signIn(withEmail: self.usernameTextField.text!, password: self.passwordTextField.text!) {(user, error) in
        if user != nil {
            print("User Has Sign In")
        }
        if error != nil {
            print(":(",error)
        }
}

Swift 4.1 FireBase User Create/Login Steps:-

STEP 1:- Register new firebase authentication Pod in to your Podfile :

pod 'Firebase/Auth'

STEP 2:- Open terminal and install pod with your related project directory path:

pod install

STEP 3:- import firebase authentication library in your UIViewController where ever you want:

import FirebaseAuth

STEP 4:- On your Registration UIButton Action write this snippet :

 Auth.auth().createUser(withEmail: (txtEmail.text ?? ""), password: (txtPass.text ?? "")) { (result, error) in
            if let _eror = error {
                //something bad happning
                print(_eror.localizedDescription )
            }else{
                //user registered successfully
                print(result)
            }
         }

STEP 5:- If you want to Sign In after Registration use this snippet on your Sign in UIButton:

  Auth.auth().signIn(withEmail: (txtEmail.text ?? ""), password: (txtPass.text ?? "")) { (result, error) in
            if let _eror = error{
                print(_eror.localizedDescription)
            }else{
                if let _res = result{
                    print(_res)
                }
            }
        }

Happy Codding ;)!!!!

Creating user in Firebase is very easy, just add firebase to your project using cocoa pods and then create a signup screen. You need email and password. Now first import Firebase

import Firebase

Then inside on viewDidLoad() method configure firebase

FIRApp.configure()

Now get email and password from textfields and use the following code for registration.

FIRAuth.auth()?.createUserWithEmail(email!, password: password!, completion: { (user: FIRUser?, error) in
   if error == nil {
       //registration successful
   }else{
       //registration failure
   }
})

Thats it.

Example of how to create users:

    Auth.auth().createUser(withEmail: email, password: password, completion: { (result, error) -> Void in
        if (error == nil) {
                UserDefaults.standardUserDefaults().setValue(result.uid, forKey: "uid")

                print("Account created :)")

                let userDict = ["Name": name!, "Major": major!, "Email": email!]

                let uid = result!.uid

                self.dismissViewControllerAnimated(true, completion: nil)
        }

        else{
                print(error)
        }
    })

Hope this helps.
