SwiftyDropbox Swift 3 - No error response when Internet connection is down

Hello,

Before upgrading to Swift 3 (Swift 2.2), I was getting an HTTP error when the wifi of my ipad was off. Now I am not getting anything. I am using the latest version of SwiftyDropbox and apart of that, eveything seems to work fine.

I already saw in here: https://github.com/dropbox/SwiftyDropbox

This:

.response { response, error in
if let response = response {
print(response)
        } else if let error = error {
print(error)
        }
    }

and actually that was the way I was doing it. It is just not giving any response when the wifi is off anymore.

When the wifi is on and there is internet connection, everything works.

What could be happening?

Thanks!

Thanks for the report! I'm not seeing this issue when testing on a device where the WiFi is off before/while making an API call though. I am getting a -1009 error.

So that we can try to reproduce this and investigate, can you let me know:

- what version of iOS you're seeing this on

- how you're constructing the client object

Thanks in advance!

Thanks for getting back to me.

I am using IOS 10.2 - Swift 3 - Xcode 8.2.1. This is what I have:

func test(){

if let client = DropboxClientsManager.authorizedClient {

let destination: (URL, HTTPURLResponse) -> URL = { temporaryURL, response in

let filePath = file.docsDir.appendingPathComponent("/file.xml")

return filePath

}

client.files.download(path: "/file.xml", overwrite: true, destination: destination)

.response { response, error in

if let response = response {

print(response)

} else if let error = error {

print(error)

}

.progress { progressData in

print(progressData)

}

When the wifi is on and internet is ok, everything works. However, if I turn the wifi off and run it again, I don't get any errors or anything. I think neither the destination and download functions are being called in this situation.

Oh, I see, thanks! For upload and download calls in particular, you won't get the failure when you're offline, since those are automatically handled on a background session. (And in fact, they should automatically continue when you get back online.)
