append(_:)

Adds an element to the end of the collection.

Declaration

mutating func append(_ newElement: Self.Element)

Parameters

  • newElement:

    The element to append to the collection.

Discussion

If the collection does not have sufficient capacity for another element, additional storage is allocated before appending newElement. The following example adds a new number to an array of integers:

var numbers = [1, 2, 3, 4, 5]
numbers.append(100)

print(numbers)
// Prints "[1, 2, 3, 4, 5, 100]"
