Can someone please define these terms

1. Objects

• Swift, objective-C and some other languages are called object-oriented programming, which means, it is based on objects rather than logic. An object contains both data(state) and code (behaviour)

• Though it may not be the best way to think of it, try to think of Objects in programming as things that can be found in the real world

• Try checking out object oriented programming definition

1. Properties

• related to understanding about Objects. An object basically encapsulates data via its properties

• Easy way to think of it is that, properties are characteristics. Imagine that you have a Car. That car is an Object. The brand of the car is BMW, and it is Blue in color. The brand of the car and the color is the properties of the car.

1. Structs vs Classes

• The key difference as Apple states, structures are always copied when passed around in the code, while classes are passed around via reference

Example of class

var theName = NameClass(name: "Jimmy")

var theSecondName = theName ---> theName and theSecondName now has a reference of the same instance

theSecondName.name = "Steven"

println(theName.name) ---> this will equal to "Steven" println (theSecondName.name) ---> this will also equal to "Steven"

Example of Structs

var theMovieName = MovieNameClass(name: "Dark Knight")

var theSecondMovieName = theMovieName ---> theMovieName and theSecondMovieName are two structs that have the same value

theSecondMovieName.name = "The Social Network"

println(theMovieName.name) --> theMovieName.name will still equal to Dark Knight

println(theSecondMovieName.name) --> theSecondMovieName.name is NOT the same as the MovieName.name. It is The Social Network

Hopefully, that helps.
