All of the code samples used in the course are available on GitHub:
You can download a zip file of everything, or if you are familiar with git, you can clone the repository. Here's a link to download a zip file of everything:
Each section in this course has a corresponding folder, for example "naming" for Section 2 and "structure" for Section 3. These folders are embedded inside the "samples" folder at the root of the repository.
Some of the code examples are embedded in unit tests to check some basic functionality, feel free to grab the code samples and do as you please with them. I have tests and code quality settings scattered about to help me write the code in a particular way, please ignore these and grab the relevant code that you see demonstrated in a video.
