title: How to run iOS app in background on iOS 12
body: <p>I have an app that runs in the background without problem on iOS 8, 9, 10, and 11. However, it stops running in the background on iOS 12.1 (it's killed after 180 seconds).</p>
  
  <p>I notice that some apps still work ok like Skype, Facebook, Viber, etc. 
  and I notice that Apple released iOS 12.2 now.</p>
  
  <p>Does anyone know how these apps can run in the background without any problems?</p>
