# asyncAfter(wallDeadline:execute:)

Schedules a work item for execution after the specified time, and returns immediately.

## Declaration

```swift
func asyncAfter(wallDeadline: DispatchWallTime, execute: DispatchWorkItem)
```

## Parameters

- `wallDeadline`: The time at which to schedule the work item for execution. Specifying the current time is less efficient than calling the doc://com.apple.dispatch/documentation/Dispatch/DispatchQueue/async(execute:) method directly. Do not specify the value in doc://com.apple.dispatch/documentation/Dispatch/DispatchWallTime/distantFuture; doing so is undefined.
- `execute`: The work item containing the task to execute. For information on how to create this work item, see doc://com.apple.dispatch/documentation/Dispatch/DispatchWorkItem.
