Multiple NSAlert buttons
I have one NSAlert with two buttons:
var al = NSAlert()
al.informativeText = "You earned \(finalScore) points"
al.messageText = "Game over"
al.showsHelp = false
al.addButtonWithTitle("New Game")
al.runModal()
It works fine, but I don't know how to recognize which button was clicked by the user.

runModal
will return the permanent positional identification of the pressed button.
This is how the values associated with your buttons are determined:
enum {
NSAlertFirstButtonReturn = 1000,
NSAlertSecondButtonReturn = 1001,
NSAlertThirdButtonReturn = 1002
};
So basically what you need to do:
NSModalResponse responseTag = al.runModal();
if (responseTag == NSAlertFirstButtonReturn) {
...
} else {

Swift 4 answer:
let alert = NSAlert()
alert.messageText = "Alert title"
alert.informativeText = "Alert message."
alert.addButton(withTitle: "First")
alert.addButton(withTitle: "Second")
alert.addButton(withTitle: "Third")
alert.addButton(withTitle: "Fourth")
let modalResult = alert.runModal()
switch modalResult {
case .alertFirstButtonReturn: // NSApplication.ModalResponse.alertFirstButtonReturn
print("First button clicked")
case .alertSecondButtonReturn:
print("Second button clicked")
case .alertThirdButtonReturn:
print("Third button clicked")
default:
print("Fourth button clicked")
}
Based on this tutorial .
