Handling different error types

In case of an error you may need to handle it:

    provider.request(target) { result in
        switch result {
        case let .Success(response):
            // Do sg on success
        case let .Failure(error):
            // Handle error here
        }
    }

Or RxSwift way:

    .doOnError{ error in
        // Handle error here
    }

You can do that by a switch on different cases of Moya.Error. In case of an .Underlying error you can also get the original NSError and its properties, e.g. code to be informed about NSURLError types like NSURLErrorTimedOut or NSURLErrorNotConnectedToInternet

        if let moyaError = error as? Moya.Error {
            switch moyaError {
            case .Data(let response):
                print(response)
                break
            case .ImageMapping(let response):
                print(response)
                break
            case .JSONMapping(let response):
                print(response)
                break
            case .StatusCode(let response):
                print(response)
                break
            case .StringMapping(let response):
                print(response)
                break
            case .Underlying(let nsError):
                // now can access NSError error.code or whatever
                // e.g. NSURLErrorTimedOut or NSURLErrorNotConnectedToInternet
                print(nsError.code)
                print(nsError.domain)
            }
        }
