Instance Method

suffix(_:)

Returns a subsequence, up to the given maximum length, containing the final elements of the collection.

Declaration

func suffix(_ maxLength: Int) -> Data

Parameters

maxLength

The maximum number of elements to return. maxLength must be greater than or equal to zero.

Return Value

A subsequence terminating at the end of the collection with at most maxLength elements.

Discussion

If the maximum length exceeds the number of elements in the collection, the result contains the entire collection.

let numbers = [1, 2, 3, 4, 5]
print(numbers.suffix(2))
// Prints "[4, 5]"
print(numbers.suffix(10))
// Prints "[1, 2, 3, 4, 5]"

Complexity: O(1) if the collection conforms to RandomAccessCollection; otherwise, O(k), where k is equal to maxLength.
