init(capacity:)
Returns an array, initialized with enough memory to initially hold a given number of objects.
Declaration
init(capacity numItems: Int)Parameters
- numItems:
The initial capacity of the new array.
Return Value
An array initialized with enough memory to hold numItems objects. The returned object might be different than the original receiver.
Discussion
Mutable arrays expand as needed; numItems simply establishes the object’s initial capacity.
This method is a designated initializer.
