Summary
This chapter introduced Xcode's Debug area. It explored the features of the console, introduced the Variables
View, and explained how to use it to modify and track variables, view their contents, and list and edit memory.
It discussed Xcode's simple breakpoint features; demonstrated how to create, edit, and delete breakpoints; and
explained how to step through code line by line, monitoring variables and results.
It introduced more advanced breakpoint features, including conditional breakpoints and actions.
Finally, it listed some of the more useful command-line options available in the underlying GDB debugging en-
vironment, explained how to explore the rest, and demonstrated how command-line options provide extra de-
bugging options that aren't included in the main graphic debugging environment.
