Trying to use Effect.promise with Firebase's DynamicLinkComponents.shortenURL about swiftrex

[npvisual]

Here's my code for reference :

let shortLinkMiddleware = EffectMiddleware<DynamicLinkAction, DynamicLinkAction, AppState, DynamicLinkComponents>.onAction { action, context, getState in
    let logger = OSLog(subsystem: Bundle.main.bundleIdentifier!, category: "ShortLinkMiddleware")
    switch action {
        case .generate:
            return .promise(
                token: "Any Hashable. Use this to cancel tasks, or to avoid two tasks of the same type",
                perform: { context, completionblock in
                    os_log(
                        "Creating new short link...",
                        log: logger,
                        type: .debug
                    )
                    let state = getState()
                    let api = context.dependencies
                    if let link = URL(string: state.invitationDeepLink),
                       let bundleid = state.bundleID {
                        api.link = link
                        api.domain = state.universalLinkBaseURL
                        api.options = DynamicLinkComponentsOptions()
                        api.options?.pathLength = .unguessable
                        api.iOSParameters = DynamicLinkIOSParameters(bundleID: bundleid)
                        
                        if let longDynamicLink = api.url {
                            DynamicLinkComponents.shortenURL(
                                longDynamicLink,
                                options: api.options,
                                completion: { url, warnings, error in
                                    if let url = url {
                                        completionblock(.response(url.absoluteString))
                                    } else {
                                        os_log(
                                            "Error shortening the URL from : %s",
                                            log: logger,
                                            type: .debug,
                                            String(describing: api.url)
                                        )
                                        completionblock(.error("Got an error while coverting short url"))
                                    }
                                }
                            )
                        } else {
                            completionblock(.error("Hmmm... No long URL available."))
                        }
                    } else {
                        os_log(
                            "Error converting the deep link or bundleid...",
                            log: logger,
                            type: .debug
                        )
                        completionblock(.error("Got an error while converting short url"))
                    }
                }
            )
        default: return .doNothing
    }
}

You are right. I didn't look yet with more time but it seems that https://github.com/SwiftRex/SwiftRex/blob/develop/Sources/CombineRex/Effect/Effect.swift#L191 is missing a @escaping clause before (OutputAction) -> Void argument of outer closure. Can you test it please and open PR if it solves? Then I can release tonight if PR is open.

CombineRex, RxSwiftRex and ReactiveSwiftRex, I couldn't find a way to write one single Effect to rule them all (yet), so there's a bit of duplication unfortunately.

Seems to fix the compilation issue. Testing it out right now.

Ok, v0.8.1 Release created, pushing Pods right now.
PS: I had to merge develop into master because of some release script fixes.
