Interfaces

The “Interface” setting in Xcode’s new-project dialog lets you pick which UI framework your app will use—either SwiftUI for a declarative, code-driven interface or Storyboard for a UIKit-based, visual layout.

Storyboard

A storyboard is an Xcode Interface Builder file that provides a visual canvas for laying out your app’s scenes and view controllers—letting you drag-and-drop UI elements, define transitions, and connect views to their controllers to visualize interface flow.

SwiftUI

SwiftUI is Apple’s modern, declarative UI framework—introduced at WWDC 2019—that lets developers build interfaces across all Apple platforms using a reactive, code-driven syntax that automatically updates when state changes.

SwiftUI is generally preferred (over storyboard) for new projects thanks to its declarative syntax, live previews, and cross-platform consistency, whereas storyboards (UIKit) still see use for legacy apps and cases requiring mature ecosystem support.
