title: What is a deprecated push segue? (iOS 8)
body: <p>I have no idea what deprecated means in this context. I am new to programming and am making my first couple of apps in Xcode 6. Today I was making a to-do list app and when connecting to the scene where the user can input a new to-do item to add to main table, I was invited to use a push segue. It mentioned that it is deprecated which it doesn't seem to have been in Xcode 5 (which is the version tutorial uses).</p>
  
  <p>Can anyone explain this to me? I know the push segue allows for backward navigation but that's about all I know!</p>
  
  <p>Thanks a lot.</p>
