How to show alert pop-up in in Cocoa on macOS?

I want to display a pop-up for displaying information in macOS, similar to a UIAlert or UIAlertController in iOS.

Is their anything in Cocoa similar to UIAlertView in iOS? How can I pop-up an alert in macOS?

Swift 5.1

func confirmAbletonIsReady(question: String, text: String) -> Bool {
    let alert = NSAlert()
    alert.messageText = question
    alert.informativeText = text
    alert.alertStyle = NSAlert.Style.warning
    alert.addButton(withTitle: "OK")
    alert.addButton(withTitle: "Cancel")
    return alert.runModal() == NSApplication.ModalResponse.alertFirstButtonReturn
}

Swift 3.0 Example :

Declaration:

 func showCloseAlert(completion: (Bool) -> Void) {
        let alert = NSAlert()
        alert.messageText = "Warning!"
        alert.informativeText = "Nothing will be saved!"
        alert.alertStyle = NSAlertStyle.warning
        alert.addButton(withTitle: "OK")
        alert.addButton(withTitle: "Cancel")
        completion(alert.runModal() == NSAlertFirstButtonReturn)
 }

Usage : 

    showCloseAlert { answer in
        if answer {
            self.dismissViewController(self)
        }
    }

you can use this method in Swift 

 func dialogOKCancel(question: String, text: String) -> Bool
        {
            let alert = NSAlert()
            alert.messageText = question
            alert.informativeText = text
            alert.alertStyle = NSAlertStyle.warning
            alert.addButton(withTitle: "OK")
            alert.addButton(withTitle: "Cancel")
            return alert.runModal() == NSAlertFirstButtonReturn
        }

And then call it in this way

let answer = dialogOKCancel(question: "Ok?", text: "Choose your answer.")

answer will be true or false on selecting "OK" or "Cancel" respectively.

You can use NSAlert in cocoa. This is same as UIAlertView in ios. you can pop-up alert by this 

NSAlert *alert = [NSAlert alertWithMessageText:@"Alert" defaultButton:@"Ok" alternateButton:@"Cancel" otherButton:nil informativeTextWithFormat:@"Alert pop up displayed"];
[alert runModal];

EDIT:

This is the latest used method as above method is deprecated now.

NSAlert *alert = [[NSAlert alloc] init];
[alert setMessageText:@"Message text."];
[alert setInformativeText:@"Informative text."];
[alert addButtonWithTitle:@"Cancel"];
[alert addButtonWithTitle:@"Ok"];
[alert runModal];

There is the cunningly named NSAlert class which can show a dialog or a sheet to present your alert.
