+1 Excellent question. Did you notice that the original SolutionViewController at index 6 has gone missing too? — trojanfoe

This has nothing directly to do with our question, but do yourself a favor and don't use uppercase object/variable names. In Objective-C, only classes, interfaces and the like should have uppercase names. — mrueg

lldb lies sometimes. It gets confused and will display the incorrect information. Try doing

po Array

you should see the correct array contents then.

This is scary... I thought Apple would've fixed this bug by now

Yes it's quite stupid. lldb will often fail to showing anything up the stack, and sometimes confuses one variable with another.
