According to documentation it's enough to override NSResponder.undoManager to provide custom NSUndoManager instance. I found it's not quite working:

• Xcode Mac application template comes with Undo menu item bind to firstResponder.undo: despite NSResponder has no undo: selector defined. Unless first responder actually respond to undo: the Undo action doesn't work
• NSFirstResponder.undoManager look up in responder chain and eventually it end up in NSWindow where the only place (that I found) that validate Undo menu item is NSWindow.validateUserInterfaceItem - that one, as turned out, only ever validate undo: action if first responder implements _getUndoManager: selector (quite private, isn't it?) - see attached disassembly

at this point 🤕 I start to think it's either documentation issue, or AppKit implementation issue. Anyway, I didn't found way to enable undo: action unless I implement one of these methods in my NSView. (notice: the view is first responder tha

Dear [Name] Investments,

I am excited to introduce Swift Studio, a cutting-edge platform for Swift development, specifically tailored to Swift on Server. As you know, Swift is quickly gaining popularity as a language for developing server-side applications, and Swift Studio is the perfect tool for developers looking to take advantage of this trend.

Swift Studio is a comprehensive development environment that streamlines the development process by providing an intuitive user interface and powerful features. With Swift Studio, developers can easily create, test, and deploy Swift applications for the server, all in one place.

One of the key features of Swift Studio is its real-time collaboration functionality, which allows multiple developers to work on the same project simultaneously. This feature enhances productivity and promotes teamwork, making Swift Studio an ideal solution for larger development teams.

Additionally, Swift Studio integrates seamlessly with other popular development tools and technologi

/// This code defines an init method for the Binding type. This method accepts three parameters:
/// 
///     An object of any type T
///     A key path to a property of type Value on that object
///     An optional UndoManager object
/// 
/// The init method sets the Binding value to the value of the property specified by the key path. It also sets the set value of the Binding to a closure that updates the value of the property at the key path and registers an undo operation with the provided UndoManager, if one is given.
/// 
/// This allows the Binding object to be used to access and update the value of the specified property on the provided object, and to register undo operations for those updates with the UndoManager.
