I have just updated to Xcode 11 and going crazy with the debugger. I am trying to simple thing of stopping at a breakpoint and stepping trough my code.
I can add the breakpoint without problem, but when the debugger stops there, is shows me a file with HEX code only. I can inspect variables, but cannot step trough the code. See screen shot. Do I have something wrong in my settings?

Xcode > Debug > Debug Workflow > always show disassembly (non check)
