My list:

Tap location for contextual menus. A lot of apps need to know exactly where a context menu is being triggered from (e.g. canvas style editors etc).
Modifier key observation during button presses/gestures etc.
Cursor support
Native Undo Manager support (SwiftUI has Environment.undoManager but it just exposes Cocoa's UndoManager which doesn't feel very SwiftUI like).
Expanded File Dialog options (e.g. adding buttons to the dialog).
The outline variant of List (List(… children: …)) is missing a lot of the flexibility of NSOutlineView (TODO: flesh this out with concrete example).

Understand your Mac and iPhone more deeply by tracing the evolution of Mac OS X from prelease to Swift. John Siracusa delivers the details.

You've got two main options:

	import Foundation
	import Synchronization

	/// Synchronization mechanism to support cooperative and cancellable waiting on a value that _might_ become available _at some point in the future_.
	public final class UncertainFuture<Value: Sendable>: Sendable {
	/// Initializes a new uncertain future.
	public init() {}

	/// Return the passed value to all currently suspended callers waiting for ``value``.
	public func complete(_ value: Value) {

	import Foundation

	// Here's a pretty typical scenario where you want to encode a polymorphic type -
	// in this case a Shape type that can be either a Square or Circle. Swift provides
	// a nice pattern for doing this in a type-safe way using enums:

	struct Circle: Codable {
	var radius: Int
	}

	// Example usage:
	// Swizzler<NSString , NSDateFormatter , NSDate *> NSDateFormatter_stringFromDate_ {
	// NSDateFormatter.class, @selector(stringFromDate:), [&](auto self, auto date) {
	// if ([NSCalendar.currentCalendar components:NSCalendarUnitWeekday fromDate:date].weekday == 4) {
	// return @"It Is Wednesday My Dudes";
	// } else {
	// return NSDateFormatter_stringFromDate_(self, date);
	// }
	// }
	// };
