High Packet Loss Mitigation

PubNub is real time, with less than 250 milliseconds latency anywhere in the world. However, even though PubNub is low latency, a device's actual physical connection to the Internet could be extremely high latency, with 50% packet loss or more. In these cases, there are a set of best practices to adopt to help mitigate user issues.

Initializing PubNub client instance

In this case, we initialize the client instance with a shorter subscribe timeout so that if a

	}

	Timer.scheduledTimer(withTimeInterval: 0.5, repeats: true) { (_) in
	let task = URLSession.shared.dataTask(with: googleURL) { (data, response, error) in
	if error != nil {
	// handle error
	print(error.debugDescription);
	} else {

	try ErrorGenerator.generateAlertControllerError()
	} catch let showError as ExampleAlertControllerError where showError == .show {
	show(alertControllerError: showError)

	fatalError(error.localizedDescription)
