# onDisappear(perform:)

Adds an action to perform after this view disappears.

```
nonisolated func onDisappear(perform action: (() -> Void)? = nil) -> some View
```

## Parameters

`action`

The action to perform. If `action` is `nil`, the
call has no effect.

## Return Value

A view that triggers `action` after it disappears.

## Discussion

The exact moment that SwiftUI calls this method
depends on the specific view type that you apply it to, but
the `action` closure doesn’t execute until the view
disappears from the interface.
