Reducer Circular reference

[Juribu]

Description

I'm getting this issue of circular reference. How do I resolve it?

The issue is with the macro as when I used the non macro version, it worked. But in a different project, the macro works with var body: some ReducerOf

import Foundation
import ComposableArchitecture

@Reducer
struct Pomodoro {
@ObservableState
struct State: Equatable {
var isTimerActive = false
}

enum Action: Equatable {
    case startTapped
    case stopTapped
}

var body: some ReducerOf<Self> {
    Reduce { state, action in
        switch action {
        case .startTapped:
            state.isTimerActive = true
            return .none
        case .stopTapped:
            state.isTimerActive = false
            return .none
        }
    }
}

}

Hi @Juribu, this is a problem with default main actor isolation in Swift 6.2 and not this library. If you really want to use that setting you will find you need to sprinkle a liberal amount of nonisolated's throughout your code. I'm sorry to say but in my opinion default main actor isolation just isn't that useful outside of an exploratory phase of building an app. It is largely incompatible with nearly every 3rd party library and even many of Apple's 1st party libraries. So I recommend turning that setting off.

Since this isn't an issue with the library I am going to convert it to a discussion. Please feel free to continue the conversation over there!
