EstablishSSL.swift

// the idea behind this is to make sure we establish an SSL connection with all 3 pubnub non-subscribe connections
// this is to try and get all three connections to be established right away. Running this frequently won't make things
// better, it just needs to run whenever the app becomes active
func establishSSL() {
  DispatchQueue.concurrentPerform(iterations: 10) { (_) in
    self.client.publish("Establish all 3 ssl connections", toChannel: "AnyChannel", withCompletion: { (status) in
      print("We just published with: \(status.debugDescription)")
    })
  }
}

// I'd put this in your AppDelegate.swift like below:
func applicationDidBecomeActive(_ application: UIApplication) {
  // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
  establishSSL()
