Day 9 - HackingWithSwift - 100DaysOfSwift Challenge

I choose a lazy person to do a hard job, Because a lazy person will find an easy way to do it. - Bill Gates

Structs - Part II

Today I learnt about:

• Initializers
• Referring to the current instance of a struct
• Lazy properties
• Static properties and methods
• Access Control

The summary of the entire day was:

• You can create your own types using structures, which can have their own properties and methods.
• You can use stored properties or use computed properties to calculate values on the fly.
• If you want to change a property inside a method, you must mark it as mutating.
• Initializers are special methods that create structs. You get a memberwise initializer by default, but if you create your own you must give all properties a value.
• Use the self constant to refer to the current instance of a struct inside a method.
• The lazy keyword tells Swift to create properties only when they are first used.
• You can share properties and methods across all instances of a struct using the static keyword.
• Access control lets you restrict what code can use properties and methods.

That's all for the Day 9 of 100DaysOfSwift!
