Operation could not be completed (IDEStackFrame Error 0.)

Question

I tried to use the three-dimensional view hierarchy viewer in the debugger by selecting "View View Hierarchy" in the "View Debug Debugging" menu. I have used it with success. However, this time I get an error message:

The operation couldn't be completed (IDEStackFrame Error 0.) 

Any idea what that means? Is there something I can do differently for repetition?

I am using iPhone 5 (32 bit) simulator in portrait mode with Xcode 6.1 (6A1052d).

Answer 1

I saw this error when I was trying to debug the hierarchy of views while I was looking at the code with the version editor. When I switched xcode to the standard editor, the debug viewing hierarchy started working again.
