ParallelUrlRequest

A group of simple methods that solves routine problem: run several api requests in parallel and then combine their results.

let profileRequest: (@escaping (Result<String, ApiError>) -> Void) -> Void = {
    apiManager.loadProfile(completion: $0)
}

let balanceRequest: (@escaping (Result<String, ApiError>) -> Void) -> Void = {
    apiManager.loadBalance(completion: $0)
}

let tariffRequest: (@escaping (Result<String, ApiError>) -> Void) -> Void = {
    apiManager.loadTariff(completion: $0)
}

let offersRequest: (@escaping (Result<String, ApiError>) -> Void) -> Void = {
    apiManager.obtainSpecialOffers(completion: $0)
}
