Instance SubscriptSwift

    subscript(_:)

    Accesses the element at the specified position.

    subscript(position: Int) -> UInt { get }

    Parameters

    position

    The position of the element to access. position must be a valid index of the collection that is not equal to the endIndex property.

    Overview

    The following example accesses an element of an array through its subscript to print its value:

    var streets = ["Adams", "Bryant", "Channing", "Douglas", "Evarts"]
    print(streets[1])
    // Prints "Bryant"

    You can subscript a collection with any valid index other than the collection’s end index. The end index refers to the position one past the last element of a collection, so it doesn’t correspond with an element.
