DAY 9

Structs, part two


As you’ve seen, structs let us combine individual pieces of data to make something new, then attach methods so we can manipulate that data.

Today you’re going to learn about some of the more advanced features of structs that make them more powerful, including access control, static properties, and laziness. Yes, laziness – Bill Gates once said, “I choose a lazy person to do a hard job, Because a lazy person will find an easy way to do it.” In Swift, laziness is an important performance optimization, as you’ll see.

Today you have six one-minute videos to watch, and as always once you’ve completed each video there’s some optional extra reading and a short test to help make sure you’ve understood what was taught.

  1. Initializers
  2. Referring to the current instance
  3. Lazy properties
  4. Static properties and methods
  5. Access control
  6. Structs summary

That’s another key Swift topic under your belt – good job! Now do the smart thing and post your progress online: it forces you to write about these things in your own words, and also encourages you to continue on to tomorrow.
