Scene editor does not display grid - xcode

Somehow my scene editor fails to display helper tools (cameras, grid etc) in the design area. As the images shows I've enabled all tools but none of them are visible. I have tried to reset to default and also did a reinstall of Xcode, without success. Any suggestions?

In recent Xcode versions you can right-click in the scene and get the menu you need:

While in the SceneKit editor, in the menu bar click on Editor > Display > Show Grid
edit: In Xcode 10 the display menu is no longer available in the editor. You have to right click in the SceneKit Editor to access it.

How to change the orientation of the editor in Xcode?

Currently, the assistant editor is on the bottom view:
I've gone to View > Change Editor Orientation, but it doesn't change anything. It just looks as it did before. I'm working on a 13 inch display if that could be a reason. I would like the display to have the storyboard and assistant editor side by side.
Thanks!
View > Change Editor Orientation does change something.
Please look at the little icon at the top right side of the editor window.
By default the assistant editor is opened at the right side
After selecting View > Change Editor Orientation the editor is opened on the bottom .
You can change the orientation temporarily by holding the ⌥ key

Xcode - Hide View Controller Scene Panel

I am completely new to Xcode. I would like to hide the View Controller Scene panel, so that I can follow on with a tutorial, and have more screen real estate. I understand that I can hide the left and right panels, but it's the panel I have highlighted in red which I want to hide. Many thanks.
There's a small icon representing that panel at the bottom of the storyboard view. It's just to the left of the spot that says "View as: iPhone 8..." in your image. Click that icon to toggle the visibility of the storyboard outline view.
There's also a menu command: Editor->Hide Document Outline that does the same thing.
Press the highlighted icon to hide the side panel.
For xcode 11.3 you may hide the preview by
Editor->Preview
make sure it is not checked.

Xcode: How to show Preview in separate window instead of showing in Assistant editor?

When I'm making edits in storyboard I know how to show the preview in the assistant editor (as shown in the below screen shot).
How to show the preview in a separate window, so that I'll be able to drag it to my the screen attached to my computer?
UPDATE: Adding few more images to clarify what is the "Storyboard Preview":
In XCode 7 I managed to do this by selecting File -> New window, then adding a preview-part teh same way you illustrate above. I then drag it to my secondary screen resize everything to give a good preview of the screen sizes I want.
