Our podcast app works, but how do we keep it working? What happens when we screw something up? In this episode, we look at Xcode's debugging tools, which let us investigate problems while the app is running, either in the simulator or on the device. We can investigate the values of variables, issue commands, preview images, and step through the code one line at a time to figure out what's going on.
