A lightweight Swift library for hierarchical state management and change propagation in SwiftUI applications using Combine and the `ObservableObject` protocol.

## Usage

```swift

import CombineObservationBroadcast

class Child: ObservableObject {

    @Published var count: Int = 0

    

    func increment() {

        count += 1

    }

}

    

class Parent: ObservableObject {

    private(set) lazy var child = ObservationBroadcast(Child(), to: self)

}

let parent = Parent()

var isChanged = false

let cancellable = parent.objectWillChange

    .sink { isChanged = true }

    

parent.child().increment()

parent.child().increment()

print(parent.child().count) // Printed "2"

print(isChanged) // Printed "true"

```

## Installation

### Swift Package Manager

Add the following to your `Package.swift` file:

```swift

    .package(url: "https://github.com/inekipelov/combine-observation-broadcast.git", from: "0.3.0")
