# onDisappear(perform:)

Adds an action to perform after this content disappears.

## Declaration

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

```

## Parameters

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

## Return Value

Return Value A CompositorContent that triggers action after it disappears.

## Discussion

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