# waitForExistence(timeout:)

Waits the specified amount of time for an element to exist.

```
func waitForExistence(timeout: TimeInterval) -> Bool
```

## Discussion

Returns <doc://com.apple.documentation/documentation/Swift/false> if the timeout expires while the element’s [`exists`](/documentation/XCUIAutomation/XCUIElement/exists) property equals <doc://com.apple.documentation/documentation/Swift/false>.
