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

switch error {
case .data(let response):
    print(response)
case .imageMapping(let response):
    print(response)
case .jsonMapping(let response):
    print(response)
case .statusCode(let response):
    print(response)
case .stringMapping(let response):
    print(response)
case .underlying(let nsError):
    // now can access NSError error.code or whatever
    // e.g. NSURLErrorTimedOut or NSURLErrorNotConnectedToInternet
    print(nsError.code)
    print(nsError.domain)
}
