ios - I want to place Table View exact down to navigation bar

Question

Please see the dashed-box area, this is extra space appearing between navigation bar & table view.

I've tried 3 things but same problem.
1. Cleared all constrains & "Add missing constrains"
2. I've used pin, & keep '0' distance to UI object above table view
3. I've used dragging method, & set vertical spacing for table view.

Answer 1

Select View Controller and Check Adjust scroll View insets.
