Resumo do curso

"If debugging is the process of removing bugs, then programming must be the process of putting them in."

Edsger W. Dijkstra

Debugging is yin to programming's yang; you can't have one without the other. However, finding bugs in programs can be an incredibly frustrating and demotivating process for developers. This course will teach you a variety of techniques to help make debugging your code easier.

Por que fazer este curso?

Debugging is one of the most fundamental processes involved in writing software. Nobody writes perfect code, and job-ready developers should know how to find and fix programming errors.

In this course, you'll learn standard methodologies for debugging software—especially for iOS applications. Additionally, you'll learn how to use Xcode’s debugging tools (breakpoints, LLDB, etc.) to squash those bugs!

Pré-requisitos

This course assumes rudimentary iOS programming experience. You should be able to scan Swift code to identify methods and errors, and make minor changes to correct them.

Lesson 1A: Debugging, Printing, Logging

In this lesson, you'll be introduced to the "So Many Bugs" app, which we'll use to solve coding mysteries throughout the course. You'll also learn about the debugging process, and how to use print statements to identify bugs.

Lesson 1B: Stepping Through Code

In this lesson, you'll learn how to use breakpoints to examine application state at any point during execution.

Lesson 2A: LLDB and Breakpoint Actions

In this lesson, you'll learn about LLDB (low-level debugger)—the debugging super tool. You'll be introduced to common LLDB commands, tips, and tricks.

Lesson 2B: Breakpoints and Visual Tools

In this lesson, you'll learn about exception and symbolic breakpoints, and how to debug your code using Xcode's visual debugging tools.

Jarrod is no stranger to trying new things for the sake of education: both a self-starter and advocate for reinventing the ways we learn, he first started challenging the status quo when he helped create virtual science labs for middle school students at the HudsonAlpha Institute for Biotechnology. While studying Computer Science at the University of Alabama in Huntsville, he started supplementing his college curriculum with online courseware, and he has never looked back. He holds a BS in Computer Science from the University of Alabama in Huntsville.
