# removeSubrange(_:)

Removes the elements in the specified subrange from the collection.

## Declaration

```swift
mutating func removeSubrange(_ bounds: Range<Self.Index>)
```

## Parameters

- `bounds`: The range of the collection to be removed. The bounds of the range must be valid indices of the collection.

## Discussion

Discussion All the elements following the specified position are moved to close the gap. This example removes three elements from the middle of an array of measurements. var measurements = [1.2, 1.5, 2.9, 1.2, 1.5] measurements.removeSubrange(1..<4) print(measurements) // Prints "[1.2, 1.5]" Calling this method may invalidate any existing indices for use with this collection. note: O(n), where n is the length of the collection.
