# Resource management Manage the images, strings, storyboards, and nib files that you use to implement your app’s interface. ## Topics ### Storyboards [Customizing the behavior of segue-based presentations](/documentation/UIKit/customizing-the-behavior-of-segue-based-presentations) Pass data between view controllers during a segue, and programmatically control when segues occur. [Dismissing a view controller with an unwind segue](/documentation/UIKit/dismissing-a-view-controller-with-an-unwind-segue) Configure an unwind segue in your storyboard file that dynamically chooses the most appropriate view controller to display next. [`UIStoryboard`](/documentation/UIKit/UIStoryboard) An encapsulation of the design-time view controller graph represented in an Interface Builder storyboard resource file. [`UIStoryboardSegue`](/documentation/UIKit/UIStoryboardSegue) An object that prepares for and performs the visual transition between two view controllers. [`UIStoryboardUnwindSegueSource`](/documentation/UIKit/UIStoryboardUnwindSegueSource) An encapsulation of information about an unwind segue. [`UIStoryboardViewControllerCreator`](/documentation/UIKit/UIStoryboardViewControllerCreator) A handler block that contains the custom initialization code for a view controller you instantiate from a storyboard. ### Assets [`UIImageAsset`](/documentation/UIKit/UIImageAsset) A container for a collection of images that represent multiple ways of describing a single piece of artwork. [`NSDataAsset`](/documentation/UIKit/NSDataAsset) An object from a data set type stored in an asset catalog. ### Nib files [`UINib`](/documentation/UIKit/UINib) An object that contains Interface Builder nib files. --- Copyright © 2026 Apple Inc.
