Initialize the library in AppDelegate and set the delegate method

[asa08]

I would like to create an AppDelegateCore and use TCA for AppDelegate processing.

enum AppDelegateCore {}

// MARK: - State
extension AppDelegateCore {
    struct State: Equatable {
    }
}

// MARK: - Action
extension AppDelegateCore {
    enum Action: Equatable {
        case didFinishLaunching
    }
}

// MARK: - Environment
extension AppDelegateCore {
    struct Environment {
    }
}

// MARK: - Reducer
extension AppDelegateCore {
    static let reducer = Reducer<State, Action, Environment>.combine(
        .init { _, action, environment in
            switch action {
                case .didFinishLaunching:
                    // TODO: Library initialization
                    return .none
            }
        }
    )
}

I tried to initialize the library with didFinishLaunchingWithOptions, but there is a delegate method in the initialization process and I am wondering how to implement it.

Please advise me if you have a better way.

Thank you.

Brandon and Stephen actually have an open-source project in the App Store called isowords that may help you here: https://github.com/pointfreeco/isowords/tree/main/Sources/AppFeature. It's certainly no "Hello World" app, but it's something you may find useful :)

Thanks for the reply.

Yes, I have read ioswords many times, but I have not found any sample that implements delegate on initialization of an external library.

For example, adjust's SDK requires the implementation of a delegate method like this.

adjustConfig?.delegate = self

This callback must be received somewhere. Here is an example of an AppDelegate.

extension AppDelegate: AdjustDelegate {
}

What do you do in such situations?

Oh, sorry.
I found a very helpful part: you are receiving the delegate callback in the client.
