What's the connection between gettable, settable and stored property, computed property

Question

I don't think I'm crystal clear on the connection between gettable, settable and stored property and computed property.

Can I say that the gettable is somehow related to stored property and settable is somehow related to computed property

Thanks so much for your time and help for a beginner like me

Answer 1

Computed properties:

• Are not really properties at all
• Do not have memory that stores their value
• Are methods that present themselves as properties
• Have a get and optional set method that can be overridden
• Can be gettable, settable, or both.
• Example usage:
  • Get a temperature in Celcius from a stored property that's stored in Kelvin
  • Get the area of a rectangle that's stored in a width and height stored property

Stored properties:

• Are just like regular variables in other languages
• Have memory that stores their value
• Have a willSet(_:) and didSet(_:) method that can be overriden
• Can always be read, but can be read only.
• Example usage:
  • Store a temperature in Kelvin
  • Store a width and a height of a rectangle
