Explain the techniques for implementing navigation and data passing between screens in a Swift app.

Implementing navigation and data passing between screens is a fundamental aspect of building Swift applications with multiple views or screens. There are several techniques available to handle navigation and data passing effectively. Let's explore some of the commonly used techniques: 1. Segues: * Segues provide a visual way to define the flow of navigation between view controllers in Interface Builder. * Create segues between view controllers by control-dragging from a UI element, such as a button, to the destination view controller. Assign an identifier to the segue and optionally configure its transition style. * To pass data between view controllers using segues, override the `prepare(for:sender:)` method in the source view controller. Access the destination view controller using the `segue.destination` property and set the required data in its properties. 2. Programmatically Instantiated View Controllers: * In certain scenarios, you may need to programmatically create and present view controllers without using segues. * Instantiate the destination view controller using its class initializer. Set any necessary data properties ....
