Thread 1, Day 4 - Monday, October 23, 2023

Agenda

  1. Discussion: Don't Repeat Yourself
    • How to keep your code tidy.
    • Capitalization conventions when authoring Swift code.
    • Vocabulary review.
    • Reviewing various solutions to the exercise from yesterday's class.
    Tip

    Here is code that exemplifies the idea of embedding one structure inside another, and here is a screenshot comparing that code to the cards themselves.

  2. Portfolio: Sharing Long Blocks of Code
    • Share code, not screenshots of code.
    • Please continue to use screenshots to show the results of code being run.
  3. Portfolio: Handling Comments on Posts
    • Do not mark comments as resolved in Notion so that the record of our conversation is preserved and easy to see at a glance.
  4. Concept: Computed Properties
    • Structures can do more than just store values - they can calculate values as well.
    Tip

    Here is the code we developed and discussed in class, and here is a screenshot showing the results when the code is run.

  5. Exercise: Describing 2D and 3D Figures
    • You have been randomly assigned a 2D or 3D figure to work with.
    • Create a new Xcode playground named Computed Properties Exercise.
    • Write a structure that models the figure you have been assigned.
      • The structure should use stored properties and computed properties.
    • Make several instances of the structure and test your work.
