Hello, In this blog we are going to learn about the MVVM in swift

Model–View–ViewModel (MVVM) is a software architectural pattern that facilitates the separation of the development of the graphical user interface (the view)

The component of the MVVM

Model:

The model is used to store the data which can access from the view model

for example

struct ImageData {
    let title: String
    let imageType: String
    let imageURL: String
   init?(data: JSON) {

   }
}

struct ImageData {

let title: String

let imageType: String

let imageURL: String

init?(data: JSON) {

}

View:

A view is used to show the user interface and content of the application to the user

You can use view controller, table view cell, collection view cell, uiview, etc

fo example:

class YourViewController: UIViewController {

    @IBOutlet weak var tableView: UITableView!
    @IBOutlet weak var searBtn: UIButton!
    @IBOutlet weak var searField: UISearchBar!

    var viewModel = YourViewModel()
    var searchText = ""
    override func viewDidLoad() {
        super.viewDidLoad()
}
}

class YourViewController: UIViewController {

@IBOutlet weak var tableView: UITableView!

@IBOutlet weak var searBtn: UIButton!

@IBOutlet weak var searField: UISearchBar!

var viewModel = YourViewModel()

var searchText = ""

override func viewDidLoad() {

super.viewDidLoad()

}

View Model:

In the View model, you can manage everything in the view controller

you can create an object for the model and put the view in the model from here

for example:

class SampleViewModal: NSObject {
    
    var sample = Sample()

   func assignValue(){
      sample = Sample(data: Json(sampleData)
   }

}

class SampleViewModal: NSObject {

var sample = Sample()

func assignValue(){

sample = Sample(data: Json(sampleData)

}

you can easily manage the data and view it from here

You need to create an object in your view controller for the view model then you need to initialize the view model then you can use the view model from your view controller
