我想弄清楚如何等待多个期货完成。我知道如何异步等待它们： summaryFuture.whenSuccess {}但这只是处理一种情况。我需要等待 summaryFuture 和sponsorFuture 完成，然后在发回响应之前处理两者。

  let summaryFuture = client.post(summaryURL) { post in
        post.http.headers.add(name: "authtoken", value: token)
        }.flatMap(to: SummaryModel.self) { (response) in
            return try response.content.decode(SummaryModel.self)
    }

  let sponsorEnrollerFuture = client.post(sponsporEnroller) { post in
        post.http.headers.add(name: "authtoken", value: token)
        }.flatMap(to: SponsorEnrollerModel.self) { (response) in
            return try response.content.decode(SponsorEnrollerModel.self)
    }
