your question seems duplicate but not duplicate.

Yes it is possible. You can refer this code.

let alertController = UIAlertController(title: "Alert Title", message: "This is testing message.", preferredStyle: UIAlertControllerStyle.Alert)
    // Background color.
    let backView = alertController.view.subviews.last?.subviews.last
    backView?.layer.cornerRadius = 10.0
    backView?.backgroundColor = UIColor.yellowColor()

    // Change Title With Color and Font:

    let myString  = "Alert Title"
    var myMutableString = NSMutableAttributedString()
    myMutableString = NSMutableAttributedString(string: myString as String, attributes: [NSFontAttributeName:UIFont(name: "Georgia", size: 18.0)!])
    myMutableString.addAttribute(NSForegroundColorAttributeName, value: UIColor.redColor(), range: NSRange(location:0,length:myString.characters.count))
    alertController.setValue(myMutableString, forKey: "attributedTitle")

    // Change Message With Color and Font

    let message  = "This is testing message."
    var messageMutableString = NSMutableAttributedString()
    messageMutableString = NSMutableAttributedString(string: message as String, attributes: [NSFontAttributeName:UIFont(name: "Georgia", size: 18.0)!])
    messageMutableString.addAttribute(NSForegroundColorAttributeName, value: UIColor.greenColor(), range: NSRange(location:0,length:message.characters.count))
    alertController.setValue(messageMutableString, forKey: "attributedMessage")


    // Action.
    let action = UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler: nil)
    action.setValue(UIColor.orangeColor(), forKey: "titleTextColor")
    alertController.addAction(action)
    self.presentViewController(alertController, animated: true, completion: nil)
