Initializers

in swift constructors are known as initializers.
initializers in Swift allow you to set up the initial state of an object and provide different options for initializing its properties.

Class designated initializers

fixing errors with default values

when we create a instance of class, no property can be left in a undetermined state.
for example following code snippet gives a error saying class samith has no initializer.

class samith {

var color : String

var age : Int

var hair : String?

var gf = "Saku"

}

in here there are two properties that not determine.
first one is color and the second one is age.
hair variable is a optional and gf variable has a value.
this error can be mitigate by creating a initializer for properties that do not have a default value or optional

what is an intializer?

its an object that runs every time when you creating a new instance of object.
primary role of the initializer is to ensure that all stored properties will be assigned a value when instance is created.

Create an Initializor for those properties that do not have a default value, or which are optional.
