where is the object bar to insert in a view?

Hello everyone. I am starting a new project in Xcode v.11. First, I create a View, with nothing. 
Now I want to insert an object, a text, a button, an image ... etc, and
I don't see the button to move the window of the objects to insert. Where has this window gone ?,
Do I have to activate something in the xcode ?,
I have worked with version 9 and 10 and all the objects to insert appeared on the right side,
but in this version I do not even see the objects nor the button in the upper right
that allowed me to display the window with the objects. Thank you !
I answer myself, and for those people who have the same problem. You have to turn on the toolbar. To do this View ---> Show Toolbar
