Answer 1

I had the same issue. I tired below solutions but didn’t worked :

1. Clean Project (cmd + shift + k) and even Clean Project Build (cmd + shift + alt + k)
2. Deleted Derived data and Module Cache content

Below workaround to this issue :

1. Move to source code file and write the IBOutlet / IBAction manually (copy paste preferred)

2. Then move to Storyboard file and Open Utilites window
3. Goto Connection Inspector
4. Then Connect the IBOutlet and IBAction written in source file with Interface Builder.

1. Close the project you are working on with.
2. Delete your project's【DerivedData】folder. (This folder may inside your project's folder, or inside
   ~/Library/Developer/Xcode/DerivedData/
   (your project)/) or somewhere else that was setup by you.
3. restart your project.

None of the tips in the best answer worked for me. Was going crazy. Then noticed that the Assistant Editor had somehow gotten set to Manual and I was on the ViewController.swift (Interface) instead of the ViewController.swift file.

Changed that and problem solved. A bit embarrassing but hey, we are all learning.
