Instance Method

max()

Returns the maximum element in the sequence.

Declaration

@warn_unqualified_access func max() -> Base.Element?
Available when Element conforms to Comparable.

Return Value

The sequence’s maximum element. If the sequence has no elements, returns nil.

Discussion

This example finds the largest value in an array of height measurements.

let heights = [67.5, 65.7, 64.3, 61.1, 58.5, 60.3, 64.9]
let greatestHeight = heights.max()
print(greatestHeight)
// Prints "Optional(67.5)"

Complexity: O(n), where n is the length of the sequence.
