Xcode not recognising new outlet and action connections

I have recently been experiencing a problem with Xcode 7 & (8 Beta) that when I try to add a new outlet or action connection I get this problem below, stating that Xcode could not find any information relating to that certain view controller. I have tried numerous steps to try to fix this problem but found none that actually fully solve my problem.

I had tried the following solutions:

  • Deleting Xcode's Derived Data

  • Deleting and reinstalling Xcode

  • Cleaning my project

  • Creating a new project and transferring the existing project into the new one

  • Programmatically creating an action or outlet

  • Removing the class name from the storyboard and creating a new one or placing the class name back into the storyboard

  • Force quitting Xcode and restarting my machine

  • And probably more!

Below I have posted my solution to this bug/problem.

Note: This solution is for Xcode 6 onwards

Open Xcode and the bug should be solved!
