Is it possible to pass an event from one View to another in the current context?

In iOS, directly passing events from one View to another in the current context is usually not practiced, as Views should not interact directly with each other. Instead, an architectural approach is used where events are passed through controllers or other intermediaries.
For example, if you need to pass an event from one UIView to another, you can:
- Use delegates (delegate pattern), where one object notifies another via a protocol.
- Apply NotificationCenter for broadcasting events.
- Use closures for callbacks.
Example with NotificationCenter:
// Sending a notification
NotificationCenter.default.post(name: Notification.Name("CustomEvent"), object: nil)
// Subscribing to a notification
NotificationCenter.default.addObserver(self, selector: #selector(handleEvent), name: Notification.Name("CustomEvent"), object: nil)
@objc func handleEvent() {
// Handle the event
}
Thus, the event is transmitted through the notification system or intermediaries, not directly between Views.
