title: Do I need cache if using CoreData
body: <p>First of all I'm new in ios/swift...</p>
  
  <p>I need to have offline mode of my app.</p>
  
  <p>I'm using Alamofire for all networking getting json, convert to objects and save into the DB (Core-Data). Wanted to know do I need to have additional cache in between (like: <a href="https://github.com/Haneke/HanekeSwift" rel="noreferrer" title="Haneke">Haneke</a>, or <a href="https://github.com/huynguyencong/DataCache" rel="noreferrer" title="DataCache">DataCache</a>) in case no internet connection or getting from CoreData? </p>
  
  <p>Is DB request fast/convenient enough?</p>
