While debugging NEPacketTunnelProvider I found that it's startTunnel and stopTunnel are being run not on the first thread.
The question is can I use DispatchQueue.main in Network Extensions? Are there any things to watch out for when dealing with async code inside Network Extensions?

Why are you wanting to control the queue in which this work is being run on?

I'd like to make so API calls in the background and then get back to original thread, for example.
What if you used a provider specific work queue and sent your work there, then everything else was run on the thread that ran the provider specific functions? Something like:
let queue = DispatchQueue(label: "NEPacketTunnelProvider", autoreleaseFrequency: .workItem)
...
self.queue.async {
// Do some work
}
