Use MobileVLCKit.framework cannot step into the vlc codes
I compiled the VLCKit 3.3.11 on macOS Catalina(10.15.4), and put the MobileVLCKit.framework into my OC project. I can debug with the VLCKit codes (these *.m files), but I cannot debug with the vlc codes(these *.c files in lib/vlc). I cannot step into these vlc functions in c-files, it just pasted by/steped over. Xcode version:11.4.1 Can anyone help me? Many thanks!
