# removeLast(_:)

Removes the specified number of elements from the end of the collection.

## Declaration

```swift
mutating func removeLast(_ k: Int)
```

## Parameters

- `k`: The number of elements to remove from the collection. k must be greater than or equal to zero and must not exceed the number of elements in the collection.

## Discussion

Discussion Attempting to remove more elements than exist in the collection triggers a runtime error. Calling this method may invalidate all saved indices of this collection. Do not rely on a previously stored index value after altering a collection with any operation that can change its length. note: O(k), where k is the specified number of elements.
