Instance Method

min()

Returns the minimum element in the sequence.

Declaration

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

Return Value

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

Discussion

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

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

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