Overview

This is a Github template repository that you can create your new repository from by clicking the big green "Use this template" button on Github.

What you get is an Xcode project with boilerplate code for a modern SwiftUI macOS app with these features already set up:

• NavigationSplitView sidebar with selection-driven detail panes and Liquid Glass design.
• MenuBarExtra scene for a native SwiftUI menu bar button.
• A sidebar search box and detail view pane-specific search in the window toolbar.
• A detail view pane with an example drop target for dropping files onto the window.
• A custom About window and Attributions window using SwiftUI Window scenes.
• A menu option for toggling whether the window should always float on top of other windows.
• A custom menu for arbitrary menu options.
• An Export menu option replacement.
• A tabbed settings window using the modern Tab API.

Modern SwiftUI Patterns

This template uses current best practices:

• NavigationSplitView instead of the deprecated NavigationView
• #Preview macro instead of PreviewProvider
• MenuBarExtra scene instead of manual NSStatusItem
• SwiftUI Window scenes instead of NSWindowController
• Modern Tab API instead of deprecated tabItem()
• Swift 6 with strict concurrency checking
• macOS 26 deployment target for Liquid Glass and latest APIs
