# addOperation(_:)

Wraps the specified block in an operation and adds it to the receiver.

## Declaration

```swift
func addOperation(_ block: @escaping @Sendable () -> Void)
```

## Parameters

- `block`: The block to execute from the operation. The block takes no parameters and has no return value.

## Discussion

Discussion This method adds a single block to the receiver by first wrapping it in an operation object. You should not attempt to get a reference to the newly created operation object or determine its type information.
