+How to transition an an older project to support Slide Over and Split View of iOS 9？
+You may find that all the demo projects was written by storyboard or xib,
+but the older project's UI is written by code！
+
+I would suggest switching to storyboards to make your life easy.
+
+I would highly recommend you watch the following WWDC videos and then think about what exactly you need to do in order to support multi tasking.
