title: iOS app get killed in background if spend more than 30 seconds, iOS 13 mostly
body: <p>I have an iOS app which uses CoreLocation and WiFi SSID information. My app was working fine until iOS 13 arrived but since then it's giving me a lot of issues especially when app goes in background. I have been using one timer in background as background task which also not work after 30 seconds and especially app got killed in background in the same time frame. I have seen some people saying that iOS 13 has been strict for background task and timing but I still have not found any direct references or links by apple which supports this claims. Is there anyone else facing the same issues then please share your insights. Thanks</p>
  
  <p>I have one background task for timer:</p>
  
  <pre><code>  var bgTask: UIBackgroundTaskIdentifier?
    var updateTimer: Timer?
  
    func applicationDidEnterBackground(_ application: UIApplication) {
  
      bgTask = application.beginBackgroundTask(withName: "MyTask", expirationHandler: {() -&gt; Void in
  
         if let bgTask = self.bgTask {
  
         application.endBackgroundTask(bgTask)
         self.bgTask = UIBackgroundTaskIdentifier(rawValue: convertFromUIBackgroundTaskIdentifier(UIBackgroundTaskIdentifier.invalid))
  
         }
  
      })
  
      DispatchQueue.main.async(execute: {() -&gt; Void in
  
          self.updateTimer = Timer.scheduledTimer(timeInterval: 2.0, target: self, selector: #selector(self.checkNetworkStatus), userInfo: nil, repeats: true)
  
      })
  
    }
  
   @objc func checkNetworkStatus() {
      print("Timer calledddd")
   }
  </code></pre>
