Nscolorpanel - strange

1

I have strange things happening when attempting to create a NSColorPanel in Swift

here is a very MINIMAL test project


import Cocoa

@main
class AppDelegate: NSObject, NSApplicationDelegate {
	func applicationDidFinishLaunching(_ aNotification: Notification) {
		let cp = NSColorPanel.shared
		cp.setTarget(self)
		cp.setAction(#selector(colorDidChange(_:)))
		cp.makeKeyAndOrderFront(self)
		cp.isContinuous = true
		cp.showsAlpha   = false
		cp.color = NSColor.green
	}

	func applicationWillTerminate(_ aNotification: Notification) {
		// Insert code here to tear down your application
	}

	func applicationSupportsSecureRestorableState(_ app: NSApplication) -> Bool {
		return true
	}

	@objc private func colorDidChange(_ sender: Any?) {
		if let cp = sender as? NSColorPanel {
			print(cp.color)

		}
	}
}

this is the display I get

anytime I change the code above (like setting a new default color)… the next run has MORE boxes at the bottom. It just gets taller and taller… I have spent all day looking for anything that might lend a clue.

Note : if you create a project and add this code… it will “probably” be ok… until you change something
