Xcode right pane (utilities pane) not applicable?

Question

I was programming using Swift in Xcode, halfway through when I wanted to edit a button using the utilities pane, I realised it became "Not Applicable". Attributes inspector, Connections inspector, etc all became "Not Applicable", only the Quick Help inspector still shows.

I have selected the button in the Storyboard.

Can anybody help with this?

Attached are screenshots..

Answer 1

Storyboard can't be opened at the start.

1. Open any file (like AppDelegate) but not storyboard.
2. Then close Xcode.
3. Open xcode again.

Works in Xcode 7.2

Answer 2

It also happened to me, I fixed it by deleting the derived data. Go to Window > Projects, select the project, and delete the derived data

Answer 3

Storyboard -> Viewcontroller -> Control -> (Identity / Attributes / Size / Connections' Inspector) window not works then follow below steps.

1. Open any file (like AppDelegate) but not storyboard.
2. Then close xcode.
3. Open xcode again.

Works fine in Almost all updated version of Xcode.
