Passing value from ChildView to ParentView

[oolxg]

Hey!

I have a parent view, let's say:

struct SearchState: Equatable {
    // some props...
    var filterState = FilterState()
}

enum SearchAction: Equitable {
    case filterAction(FilterAction)
    ...
}

let searchReducer = .combine(filterReducer, ...)

and child view:

struct FilterState: Equatable {
    var tags: [String] = []
    // some other props...
}

let filterReducer = ...

How FilterState.tags can be accessed inside searchReducer?
Should i hijack filterAction inside searchReducer?
Or is there any other way?

The FilterState.tags can be accessed in the searchReducer via the state, that is passed: state.filterState.tags.

Btw.: the searchReducer should use the filterReducer via .pullback, e.g.

let searchReducer = Reducer<SearchState, SearchAction, ...>.combine {
    filterReducer.pullback(state: \.filterState, action: /SearchAction.filterAction, environment: { ... }),
    Reducer { state, action, _ in
       print(state.filterState.tags)
       return .none
    }
}
