Initializer

init(capacity:)

Initializes a newly allocated mutable dictionary, allocating enough memory to hold numItems entries.

Declaration

init(capacity numItems: Int)

Parameters

numItems

The initial capacity of the initialized dictionary.

Return Value

An initialized mutable dictionary, which might be different than the original receiver.

Discussion

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

This method is a designated initializer of NSMutableDictionary.
