Instance Method

# lastIndex(of:)

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

## Declaration

Available when Element conforms to Equatable.

## Parameters

`element`

An element to search for in the collection.

## Return Value

The last index where `element` is found. If `element` is not found in the collection, this method returns `nil`.

## Discussion

After using `lastIndex(of:)` to find the position of the last instance of a particular element in a collection, you can use it to access the element by subscripting. This example shows how you can modify one of the names in an array of students.

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

### 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(where: (Element) -> Bool) -> Int?`

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

`func min() -> Element?`

Returns the minimum element in the sequence.

`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.
