Whilst implementing several HTTP calls, I noticed some strange behaviour on the URLSession. As far as I know, URLSession data tasks used to immediately throw an error when the network connection was unavailable (error -1009 The Internet connection appears to be offline).
I'm now performing network requests too, and while executing a request in flight mode, the request runs for as long as the timeout, before failing. I tried creating a custom configuration that should prevent this, but this does not work. How can I re-enable or configure the behaviour where a request will immediately crash when there is no connection?
The configuration documentation appears to be inconsistent or incorrect.
let url = URL(string: "https://www.google.com/")!
let config = URLSessionConfiguration.default
config.waitsForConnectivity = false
config.timeoutIntervalForRequest = 2
config.timeoutIntervalForResource = 0
URLSession(configuration: config).dataTask(with: url) { d, r, e in
print(d?.count, (r as? HTTPURLResponse)?.statusCode, e?.localizedDescription)
}.resume()
