Secure text .echosbullets not working for password field

问题

Here's what I've got:

@IBOutlet weak var password: NSSecureTextField! 
@IBOutlet weak var shwpswd: NSButton! //Checkbox
@IBOutlet weak var pswdcell: NSSecureTextFieldCell! //Cell


@IBAction func shwpswd(_ sender: Any) {
    if(shwpswd.state == 1) {
        pswdcell.echosBullets = false // Turn the Secure text into regular text
    }
    else if(shwpswd.state == 0) {
        pswdcell.echosBullets = true // Secure text
    }
}

Everything seems to run fine, except the text in the password field doesn't change states between echoing bullets and echoing the real text. Everything is linked together properly too - Cell is within the text field, password button is in the view and the outlet works. I'm wondering if this is another one of the "Swift on mac < Swift on iOS cases".

EDIT: Here is the final solution, should anyone care to see it:

@IBOutlet weak var shwpswd: NSButton! //Checkbox
@IBOutlet weak var visPswd: NSTextfield! //hidden regular box to show chars
@IBOutlet weak var password: NSSecureTextField!    //visible initial secure box
@IBAction func shwpswd(_ sender: Any) {
    if(shwpswd.state == 1) {
        self.visPswd.stringValue = self.password.stringValue //Sync both the text fields
        self.password.isHidden = true //hide the secure field
        self.visPswd.isHidden = false //show the real character echo field
    }
    else if(shwpswd.state == 0) {
        self.password.stringValue = self.visPswd.stringValue //Sync the two
        self.password.isHidden = false // Inverse of above
        self.visPswd.isHidden = true
    }
}

Note the text fields password and visPswd are the same size and position in the view - one remains hidden at all times to avoid overlapping. When the user enters values in either the password or visPswd field, it syncs with the other field when the checkbox state is changed.

You can accomplish what you want adding a second text field in top of your secure field. Add an IBAction to your check box to switch your fields isHidden property and copy the other textField stringValue and make it the first responder. Your implementation should look like something like this:

import Cocoa

class ViewController: NSViewController {
    @IBOutlet weak var password: NSSecureTextField!
    @IBOutlet weak var showPassword: NSTextField!
    @IBOutlet weak var shwpswd: NSButton!
    override func viewDidLoad() {
        super.viewDidLoad()
        shwpswd.state = .off
        showPassword.isHidden = true
    }
    override func viewDidAppear() {
        super.viewDidAppear()
        password.window?.makeFirstResponder(password)
    }
    @IBAction func showHidePassword(_ sender: NSButton) {
        showPassword.isHidden = !showPassword.isHidden
        password.isHidden = !password.isHidden
        if !showPassword.isHidden {
            showPassword.stringValue = password.stringValue
            showPassword.becomeFirstResponder()
        } else {
            password.stringValue = showPassword.stringValue
            password.becomeFirstResponder()
        }
    }
}
