Learn how to add comments to your code to make it easier to understand, organize code for display and navigation in the jump bar, and use markup syntax to format comment text.
- [Instructor] Swift promotes writing expressive code…that reads well, and is easy to understand.…A well-written method, for example,…should read like a sentence.…Add fresh vegetables to wok returns a meal.…Still, adding comments to your code…can go a long way towards helping your fellow programmers…understand how to work with the code you've written,…so it has to provide details…about parameters from method or example use cases.…And I'll be honest, I've lost count of how many times…I've looked back on old code that I've written…and wondered, what was I thinking?…The syntax to write a single-line comment…is to write two forward slashes,…followed by your comment text.…
Single-line comments also support using landmarks,…which will be displayed in the jump bar,…and that runs along the top of the source editor…and is currently displaying the playground file name.…Because the jump bar does not display landmarks…in the main playground file,…I'll show them in a separate source file…that I've added to the playground sources folder,…
