You could manage the button state yourself without a lot of code.
@IBOutlet var button1: NSButton // tag = 0
...
@IBOutlet var buttonN: NSButton // tag = N - 1
private var selectedPaletteButtonIndex: Int = 0
private var paletteButtons: [NSButton]
override func viewDidLoad()
{
super.viewDidLoad()
paletteButtons =
[
button1,
...
buttonN
]
paletteButtons[selectedPaletteButtonIndex].state = .on
}
@IBAction func paletteChanged(_ button: NSButton)
{
let newSelectedPaletteButtonIndex = button.tag
if selectedPaletteButtonIndex != newSelectedPaletteButtonIndex
{
paletteButtons[selectedPaletteButtonIndex].state = .off
paletteButtons[newSelectedPaletteButtonIndex].state = .on
selectedPaletteButtonIndex = newSelectedPaletteButtonIndex
}
}
