To set custom color and font subclass UIAlertController like this.

import UIKit

class StyledAlertController: UIAlertController {

    private var cancelText:String?

    override func viewDidLoad() {
        super.viewDidLoad()
        view.tintColor = YourColor
    }

    override func viewWillLayoutSubviews() {
        super.viewWillLayoutSubviews()
        findLabel(view)
    }

    private func findLabel(scanView: UIView!) {
        if (scanView.subviews.count > 0) {
            for subview in scanView.subviews {
                if let label:UILabel = subview as? UILabel {
                    if (cancelText != nil && label.text == cancelText!) {
                        dispatch_async(dispatch_get_main_queue(),{
                            label.textColor = YourColor
                            label.tintColor = YourColor
                        })
                    }
                    let font:UIFont = UIFont(name: YourFont, size: label.font!.pointSize)!
                    label.font = font
                }
                findLabel(subview)
            }
        }
    }
}

Use like this (as you normally would)

let StyledAlertController = StyledAlertController(title: "My Title", message: "My Message", preferredStyle: .ActionSheet)

let cancelAction:UIAlertAction = UIAlertAction(title: "Cancel", style: .Cancel) { action -> Void in
        print("Cancel Action Click")
    }
actionSheetController.addAction(cancelAction)

let anotherAction:UIAlertAction = UIAlertAction(title: "Another Action", style: .Default) { action -> Void in
        print("Another Action Click")
    }
actionSheetController.addAction(anotherAction:UIAlertAction)

presentViewController(actionSheetController, animated: true, completion: nil)
