Instance Method

# min()

Returns the minimum element in the sequence.

## Declaration

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.

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

### Finding Elements

`func contains(Element) -> Bool`

Returns a Boolean value indicating whether the sequence contains the given element.

`func contains(where: (Element) -> Bool) -> Bool`

Returns a Boolean value indicating whether the sequence contains an element that satisfies the given predicate.

`func allSatisfy((Element) -> Bool) -> Bool`

Returns a Boolean value indicating whether every element of a sequence satisfies a given predicate.

`func first(where: (Element) -> Bool) -> Element?`

Returns the first element of the sequence that satisfies the given predicate.

`func firstIndex(of: Element) -> Int?`

Returns the first index where the specified value appears in the collection.

`func index(of: Element) -> Int?`

Returns the first index where the specified value appears in the collection.

Deprecated
`func firstIndex(where: (Element) -> Bool) -> Int?`

Returns the first index in which an element of the collection satisfies the given predicate.

`func last(where: (Element) -> Bool) -> Element?`

Returns the last element of the sequence that satisfies the given predicate.

`func lastIndex(of: Element) -> Int?`

Returns the last index where the specified value appears in the collection.

`func lastIndex(where: (Element) -> Bool) -> Int?`

Returns the index of the last element in the collection that matches the given predicate.

`func min(by: (Element, Element) -> Bool) -> Element?`

Returns the minimum element in the sequence, using the given predicate as the comparison between elements.

`func max() -> Element?`

Returns the maximum element in the sequence.

`func max(by: (Element, Element) -> Bool) -> Element?`

Returns the maximum element in the sequence, using the given predicate as the comparison between elements.
