UIAlertView is deprecated in iOS 8, But Swift supports iOS7 and you can not use UIAlertController on iOS 7. Add the following method to solve the issue :

func showAlert(title:NSString, message:NSString,owner:UIViewController) {
    if let gotModernAlert: AnyClass = NSClassFromString("UIAlertController") {
        var alert = UIAlertController(title: title, message: message, preferredStyle: UIAlertControllerStyle.Alert)
        alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: nil))
        owner.presentViewController(alert, animated: true, completion: nil)
    }
    else {
        let alertView = UIAlertView(title: title, message: message, delegate: self, cancelButtonTitle: "Cancel", otherButtonTitles: "OK")
        alertView.alertViewStyle = .Default
        alertView.show()
    }
}

and call the method anywhere from the code like this :

showAlert(APP_NAME,message: "Add your alert message here" ,owner: self)
