title: The best way to make a viewcontroller for different screens
body: <p>I would like to know which is the best way to make a view controller for iOS 9 swift 2 xcode 7, for different iPhone screens?</p>
  
  <p>I have tried to make it with constrains but from iphone 4s to iphone 6s screens we can see wide gaps between the icons and text fields etc.</p>
  
  <p>What i'm thinking is to make different view controllers for each screen (5.5inches, 4.7inches, 3.5inches) and to make my app check with which screen the user is opening the app and load the unigue view controller for this screen.</p>
  
  <p>Or maybe there is a better way but im new to swift 2.0 so i'm asking for your help!</p>
  
  <p>Thanks a lot for your time.</p>
