Initializer

init(capacity:)

Returns an initialized mutable set with a given initial capacity.

Declaration

init(capacity numItems: Int)

Parameters

numItems

The initial capacity of the set.

Return Value

An initialized mutable set with initial capacity to hold numItems members. The returned set might be different than the original receiver.

Discussion

Mutable sets allocate additional memory as needed, so numItems simply establishes the object’s initial capacity.

This method is a designated initializer for NSMutableSet.
