Series of posts about building Redux-like Single Source of Truth in SwiftUI.
Single source of truth eliminates tons of bugs produced by creating multiple states across the app. The main idea here is describing the whole app state by using a single struct or composition of structs. A single state for the whole app makes it easier to debug and inspect.

import Foundation
import Combine
typealias Reducer<State, Action, Environment> =
(inout State, Action, Environment) -> AnyPublisher<Action, Never>?
final class Store<State, Action, Environment>: ObservableObject {
@Published private(set) var state: State
private let environment: Environment
private let reducer: Reducer<State, Action, Environment>
private var effectCancellables: Set<AnyCancellable> = []
init(
initialState: State,
reducer: @escaping Reducer<State, Action, Environment>,

) {
self.state = initialState
self.reducer = reducer
self.environment = environment
}
func send(_ action: Action) {
guard let effect = reducer(&state, action, environment) else {
return
}
effect
.receive(on: DispatchQueue.main)
.sink(receiveValue: send)
.store(in: &effectCancellables)
}
}
