MenuBuilder

A function builder for NSMenus, similar in spirit to SwiftUI’s ViewBuilder.

Usage example (see demo or read the documentation for more details):

let menu = NSMenu {
  MenuItem("Click me")
    .onSelect { print("clicked!") } 
  MenuItem("Item with a view")
    .view {
      MyMenuItemView() // any SwiftUI view
    }
  SeparatorItem()
  MenuItem("About") {
    // rendered as disabled items in a submenu
    MenuItem("Version 1.2.3")
    MenuItem("Copyright 2021")
  }
  MenuItem("Quit")
    .shortcut("q")
    .onSelect { NSApp.terminate(nil) }
}

// later, to replace the menu items with different/updated ones:
menu.replaceItems {
  MenuItem("Replaced item").onSelect { print("Hello!") }
}

Note that there is no way to preserve the existing menu items, although it should be possible to implement that — feel free to open an issue or PR adding update support if you want it!

• (Potentially BREAKING) When your app has a deployment target of macOS 12 or newer, passing a string literal to MenuItem("Title Here") will now create a String.LocalizationValue, which will make it easier to localize your app if you use MenuBuilder.
  • If your app is not localized (or your deployment target is macOS 11 or older), you shouldn’t notice any changes.
  • If your app is localized, review your UI that uses MenuBuilder and make sure that you’re not getting any unexpected translations. You can migrate to MenuItem(verbatim: "Title Here") if you want to opt out of the new behavior.

New Features:

• Add action and tag modifiers (Thanks @patr0nus!)
• Update the SwiftUI custom view wrapper to use Auto Layout (Thanks @rurza!)
• Add support for menu item titles using AttributedString on macOS 12+
• Add a convenience initializer to NSMenu that takes a title and an @MenuBuilder closure
• Deprecate the MenuItem(_:children:) initializer in favor of MenuItem(title).submenu { ... children ... }
• Add an onSelect(target:action:) convenience method to set the target and action at the same time.

Bugfixes:

• Update the SwiftUI custom view wrapper’s selection indicator to match the menu styling of macOS Big Sur and later (Thanks @rurza!)
• Make the parameter to toolTip optional (Thanks @mlch911!)
• update() is now called on an NSMenu when you use the replaceItems API

• (BREAKING) Migrate to @resultBuilder (Xcode 12.5+ is now required)
• Apply modifiers to shortcuts
• Add a MenuItem.set(WriteableKeyPath, to: Value) method to make it easier to customize the menu item
• Add a MenuItem.apply { menuItem in } method to allow arbitrary customization of the menu item
• Add IndentGroup to make it easier to indent several adjacent menu items
• Add CustomMenuItem which allows you to include custom subclasses of NSMenuItem in a MenuBuilder
