Debug Breakpoints does not work on engine code in Xcode

I downloaded latest version fo UE4 (v4.24.2) with “Editor symbols for debugging” checked option.
I created xCode template project and set breakpoint in game code, everything works well.
But breakpoints in Engine code (not game code) not triggering. Editor debugging symbols do not help is this situation. Please, how to make breakpoints working in Engine code?
