CombineObservationBroadcast

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

Usage

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"
