Swift Custom Subscript

Swift can easily add subscript to a custom class where parameters and return values can be defined as any type in the class:

Subscript (parameters), returntype {    get  {        //return somevalue      }    set  (newvalue) {        //setsomevalue ()     }} /* */

Subscripts are usually shortcuts to accessing certain methods, even when the nsarray operation.

As with computed properties, subscripts can appear in read-only or write-only mode, such as read-only subscript:

Subscript (parameters), returntype {    return  somevalue}/* * /

If multiple subscripts are supported in a class, and the parameter type is the same, you can explicitly declare the type when you access the subscript:

Let Player:type = class[(3,4)]/** *
