How is the VVM architecture implemented in your…

The project used MVVM.

Components:

Model: Represents data and business logic. These are structures or classes that do not depend on the UI.
View: Responsible for displaying data and handling user input. This is a UIView or UIViewController. The View is passive; it only displays what the ViewModel tells it.
ViewModel: Acts as an intermediary between the Model and the View. It contains presentation logic and transforms data from the Model into a format suitable for display in the View. The ViewModel provides observable properties that the View subscribes to. The ViewModel does not have a direct reference to the View.

Interaction:

The View subscribes to observable properties of the ViewModel.
The ViewModel retrieves data from the Model (if necessary).
The ViewModel processes the data and updates its observable properties.
The View receives notifications of changes in observable properties and updates its interface.
The View sends user actions (e.g., button presses) to the ViewModel via closures or delegates.
The ViewModel processes actions, may interact with the Model, and if necessary, updates its observable properties.

Binding:

ReactiveSwift (or Combine, depending on the iOS version) was used to implement reactive binding between the View and the ViewModel. This ensures automatic UI updates when data in the ViewModel changes.

// Example in ViewModel
let title: Property<String>
private let mutableTitle: MutableProperty<String>

init(...) {
    self.mutableTitle = MutableProperty("")
    self.title = Property(mutableTitle)
    // ...
}

func loadData() {
    // ...
    mutableTitle.value = loadedData.title
    // ...
}

// Example in View/ViewController
viewModel.title.signal.observeValues { [weak self] title in
    self?.titleLabel.text = title
}

// Sending user action
button.reactive.controlEvents(.touchUpInside).observeValues { [weak self] _ in
    self?.viewModel.buttonTapped()
}

Advantages:

Better testability of the ViewModel.
Separation of responsibilities between layers.
Improved maintainability of the code.
Easier UI replacement without changing business logic.
