Type Methods
When a particular instance of a method is called, it is called as an Instance method; and
when the method calls a particular type of a method, it is called as 'Type Methods'. Type
methods for 'classes' are defined by the 'func' keyword and structures and enumerations
type methods are defined with the 'static' keyword before the 'func' keyword.
Type methods are called and accessed by '.' syntax where instead of calling a particular
instance the whole method is invoked.
class Math
{
class func abs(number: Int) - > Int
{
if number < 0
{
return (-number)
}
else
{
return number
}
}
}struct absno
{
static func abs(number: Int) - > Int
{
if number < 0
{
return (-number)
}

{
return number
