How can I access hidden/abbreviated stack frames in the Xcode 6 debugger (where did the stack trace abbreviation slider go?)

Question

In Xcode

In Xcode 6 when the app crashes or when the debugger stopped at a breakpoint we get a stack trace that looks like this in the sidebar:

I can click on the different stack frames/methods to jump to the places in the code and inspect the local variables. However, several of the stack frames which belong to the framework are abbreviated.

In Xcode 4 it looked like this:

Notice that there was a slider at the bottom. Dragging it to the far right revealed all of the stack frames and made all of them selectable.

I need that functionality in Xcode 6, so my question is any of these:

• How can I show all stack frames, even the framework ones
• How can I access a hidden stack frame to inspect the local variables (e.g. parameters to a method call in a framework)
• Where did the slider go and what am I supposed to do without it?

Answer 1

The slider is gone. Now there is a button in the bottom left-hand corner of the debugger pane saying

Show only stack frames with debug symbols and between libraries

You have to uncheck it:

The buttons are described in Debug Navigator Help.
