Why do integers not conform to the AnyObject protocol?

Question

Why can I have an [AnyObject] array and put a bunch of different sized types in it ...

var a = [AnyObject]()
a.append(Int(1))
a.append(Float64(3         


        

Answer 1

Because Int is a value Type.

AnyObject refers to referance types (classes) not value types

Any refers to referance types + value types (structs + classes)

You must use Any for valueTypes, not AnyObject

Value Types > generally structs, enums, bla bla..

Referance Types > generally classes

There are two types of variables > Referance types and value types

Referance types are pointer types and generally contains a ram address value where the original data is stored

Value types are not addresses . They directly contain the variable value

Int asd = 3 (asd directly contains 3)

Int, Float, number types,... Date are almost always struct(value type) in most computer languages.

String is almost always a hybrid in most computer languages

ViewControllers, Views, Buttons, ...arrays, dictionaries, ... and your custom defined classes are referance types
