Breakpoints not breaking in objc code

I have a mixed swift / objc app in XCode 10. I am trying to debug one of the objc classes, but none of my breakpoints within the objc class cause a break into the debugger. I know the methods are being called because I can put NSLog(...) inside them and see the logs printed as I run.


When I set a breakpoint in the calling code (swift), I am unable to step into the objc code. Does anyone have any ideas how to debug this?

Solved: apparently my "Debug Information Format" in the build settings had been set to "none". Oddly enough this didn't effect my ability to debug swift code, only objc.
