# canPerformUnwindSegueAction(_:from:withSender:) Called on a view controller to determine whether it wants to respond to an unwind action. ``` func canPerformUnwindSegueAction(_ action: Selector, from fromViewController: UIViewController, withSender sender: Any) -> Bool ``` ## Parameters `action` The unwind action to invoke on your view controller. `fromViewController` The view controller that initiated the unwind action. `sender` The object that triggered the action. ## Return Value if the view controller wants to handle the unwind action, otherwise . ## Discussion When an unwind segue is triggered, UIKit uses this method and the [`allowedChildrenForUnwinding(from:)`](/documentation/UIKit/UIViewController/allowedChildrenForUnwinding(from:)) method to locate a suitable view controller to handle the unwind segue. The default implementation of this method returns when the current view controller implements the `action` method and is not the same view controller as the one in the `fromViewController` parameter. You can override this method as needed to change the default behavior. For example, you might return if the current view controller does not make a suitable return target when unwinding from the specified view controller. --- Copyright © 2026 Apple Inc.
