`po` gives `error: :1:1: error: use of unresolved identifier`

Question

I have this problem with po in the console where trying to output a function works in itself, but outputting a variable or constant doesn\'t.

Answer 1

I encountered a similar issue but I already had the correct configuration, all optimisations set to None. However I still didn't get any values.

After some further digging I found out that the issue originated from Xcode being unable to the resolve the types:

(lldb) frame variable self

That led me to this question: xcode 8 Debugger 'Could not resolve type' where the issue is described and the bridging header seems to cause issues.

With my project not having any bridging headers I studied the build settings once more and found this setting

This was initally set to YES. After changing the it to NO symbols are working again.

SWIFT_INSTALL_OBJC_HEADER = NO
