How can i create a thread inside NEPacketTunnelProvider?

Network Extension providers don’t place any specific limits on creating threads within the provider. You can use whatever threading API you want. In general I recommend:

• NSThread

  (

  Thread

  in Swift) for most use cases

• pthreads if you’re writing cross-platform code

WARNING A common mistake is to use dispatch to create a long-live thread. For example, something like this:

dispatch_async(dispatch_get_global_queue(…), ^{
    … block here indefinitely …
});

This is problematic because it ties up a dispatch worker thread doing stuff that’s not related to dispatch. If you want to create a long-lived thread for running some subsystem within your app, use a threading API not dispatch.

Share and Enjoy
