Here's a quick step-by-step guide for swift, based on the excellent answers by @Adrian, Travis B and Thomas Kilian.

The goal will be to subclass the NSApplication, instead of the NSTextField. Once you have created this class, do link it in your "principal Class" setting of the Info.plist, as stated by Adrian. As opposed to the Objective-C folks, we swiftlers will have to add an additional prefix to the principalClass configuration. So, because my Project is called "Foo", I am going to set "Principal Class" to "Foo.MyApplication". You will get an "Class MyApplication not found" runtime error otherwise.

The contents of MyApplication read as follows (copied and adapted from all the answers given so far)

import Cocoa

class MyApplication: NSApplication {
    override func sendEvent(event: NSEvent) {
        if event.type == NSEventType.KeyDown {
            if (event.modifierFlags & NSEventModifierFlags.DeviceIndependentModifierFlagsMask == NSEventModifierFlags.CommandKeyMask) {
                switch event.charactersIgnoringModifiers!.lowercaseString {
                case "x":
                    if NSApp.sendAction(Selector("cut:"), to:nil, from:self) { return }
                case "c":
                    if NSApp.sendAction(Selector("copy:"), to:nil, from:self) { return }
                case "v":
                    if NSApp.sendAction(Selector("paste:"), to:nil, from:self) { return }
                case "z":
                    if NSApp.sendAction(Selector("undo:"), to:nil, from:self) { return }
                case "a":
                    if NSApp.sendAction(Selector("selectAll:"), to:nil, from:self) { return }
                default:
                    break
                }
            }
            else if (event.modifierFlags & NSEventModifierFlags.DeviceIndependentModifierFlagsMask == (NSEventModifierFlags.CommandKeyMask | NSEventModifierFlags.ShiftKeyMask)) {
                if event.charactersIgnoringModifiers == "Z" {
                    if NSApp.sendAction(Selector("redo:"), to:nil, from:self) { return }
                }
            }
        }
        return super.sendEvent(event)
    }
