Pass UIApplication.OpenURLOptionsKey in action from AppDelegate.

[asa08]

I want to pass UIApplication.OpenURLOptionsKey from AppDelegate by action.
Do you know of any good ways to do this?

AppDelegate

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey: Any] = [:]) -> Bool {
    viewStore.send(.openUrl(url: url))
}

Core

extension AppDelegateCore {
    struct Environment {
        var twitterClient: TwitterClient
    }
}

extension AppDelegateCore {
    static let reducer = Reducer<State, Action, Environment>.combine(
        .init { state, action, environment in
            switch action {
                case .openUrl(let url):
                    // To give it here
                    let result = environment.twitterClient.application(url: url, option: ## OPTION ##)
                    ...
            }
        }
   )
}

TwitterClient

import TwitterKit

protocol TwitterClient {
    func application(url: URL, options: [UIApplication.OpenURLOptionsKey: Any]) -> Bool
}

final class TwitterClientImpl: TwitterClient {
    func auth(url: URL, options: [UIApplication.OpenURLOptionsKey: Any]) -> Bool {
        TWTRTwitter.sharedInstance().application(UIApplication.shared, open: url, options: options)
    }
}

Thanks for looking.

Hey @asa08! You can put this dictionary beside the URL in openUrl. But doing so prevents automatic Equatable synthesis for your Action. One way to do this while keeping your Action Equatable for testing is to create a wrapper type:

public struct OpenUrlRequest: Equatable {
  let url: URL
  let options: [UIApplication.OpenURLOptionsKey: Any]
 
  public static func == (lhs: Self, rhs: Self) -> Bool { lhs.url == rhs.url }
}

and you can refactor openUrl(URL) into openUrl(OpenUrlRequest), so you can send:

viewstore.send(.openUrl(.init(url: url, options: options)))

The sub-optimal Equatable conformance will weaken your tests, but it should be relatively OK.

Thank you @tgrapperon for the perfect solution, I have solved my problem :)
