Xcode missing Debug View Hierarchy button
Hi
I'm working through a Swift tutorial for Xcode and reached a section which describes using the Debug View Hierarchy button to illustrate certain features of the App I'm developing. When I open the debug area I only have the close icon and a blue right pointing arrow.
An on-line search for help suggested that the View Debugging option for the Scheme might be disabled but this all seems OK on my set up. Which is: iOS - Big Sur 11.0.1 and Xcode v12.2. Does anyone know what the problem might be?
