# init(minimumCapacity:)

Creates an empty set with preallocated space for at least the specified number of elements.

## Declaration

```swift
init(minimumCapacity: Int)
```

## Parameters

- `minimumCapacity`: The minimum number of elements that the newly created set should be able to store without reallocating its storage buffer.

## Discussion

Discussion Use this initializer to avoid intermediate reallocations of a set’s storage buffer when you know how many elements you’ll insert into the set after creation.
