What is the lifecycle of onReceive subscriptions in SwiftUI views?

I'm trying to better understand how the onReceive modifier behaves in SwiftUI, specifically how its subscription lifecycle relates to view updates.

Consider this example:

TextField("Name", text: $name)
    .onReceive(Just(name)) { value in
        print(value)
    }

This closure runs every time name changes. A common explanation is that SwiftUI recomputes body, which creates a new Just(name) publisher each time.

However, this raises some questions for me about how onReceive actually works internally:

When SwiftUI recomputes body, is the onReceive modifier recreated and resubscribed?

Does SwiftUI automatically cancel the previous subscription when the view updates?
