Hi Reader’s,

This blog includes the concept of how to store user information in NSUserDefaults in swift language. Below is the code in swift language for the same:-
 

import UIKit
import Foundation

class RegisterViewController: UIViewController {
    
    @IBOutlet weak var txtFirstName: UITextField!
    
    @IBOutlet weak var txtLastName: UITextField!
    
    @IBOutlet weak var txtEmailId: UITextField!
    
    @IBOutlet weak var txtPassword: UITextField!
    
    override func viewDidLoad() {
        super.viewDidLoad()
    }
    
    
    @IBAction func btnSignUp(sender: AnyObject) {
        
        // Save user details in NSUserDefaults
        
        let defaults = NSUserDefaults.standardUserDefaults()
        defaults.setObject(txtFirstName.text, forKey: "firstName")
        defaults.setObject(txtLastName.text, forKey: "lastName")
        defaults.setObject(txtEmailId.text, forKey: "emailId")
        defaults.setObject(txtPassword.text, forKey: "password")
        
        // Shows alert after saving the user details in NSUserDefaults
        
        let alert = UIAlertController(title: "Alert", message: "User Detail Stored Successfully", preferredStyle: UIAlertControllerStyle.Alert)
        alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: nil))
        self.presentViewController(alert, animated: true, completion: nil)
        
        // Clear the textfields 
        
        txtFirstName.text=""
        txtLastName.text=""
        txtPassword.text=""
        txtEmailId.text=""
        
        
    }
    
}
