    Hopefully this is very simple, but I was having trouble with the TKAlert appearing behind the view so I created a simple application that recreated the problem. It is set up as follows:

    There are three view controllers which are shown in the 'simpleStoryboard.png' attachment. Each one has a next and/or back button and an alert button that shows a TKAlert.  The alert shows as expected on the first two but on the third it shows behind the view controller (if i make the master view of the third one transparent I can see the alert). The problem is not with the third controller because if you enter the story board at the second, it will work for the second and third.

    What am I missing here?

    For reference here is generally what each of the controllers classes look like:


    import UIKit
    class SecondController: UIViewController, TKAlertDelegate {
        @IBAction func backButton(sender: AnyObject) {
        @IBAction func nextButton(sender: AnyObject) {
        func OpenNextController(){
            performSegueWithIdentifier("segueTwo", sender: self)
        func goHome() {
            dismissViewControllerAnimated(true, completion: nil)
        @IBAction func alertButton(sender: AnyObject) {
        //MARK: TKAlert
        func showAlert(sender: AnyObject) {
            print("Trying to show alert...")
            let alert = TKAlert()
            alert.delegate = self
   = 3
            alert.title = "TK Alert!"
            alert.message = "Is this working?"
   = 10
   = UIEdgeInsetsMake(5, 5, 5, 5)
   = 0
   = UIColor(red:0.349, green:0.349, blue:0.349, alpha:1.00)
   = -0.5
   = 0
            alert.alertView.layer.shadowOpacity = 0.6
            alert.alertView.layer.shadowRadius = 3
            alert.alertView.layer.shadowOffset = CGSizeMake(0, 0)
            alert.alertView.layer.masksToBounds = false
   = UIColor.whiteColor()
            alert.buttonsView.backgroundColor = UIColor.whiteColor()
   = TKAlertAnimation.SlideFromTop
            var action = alert.addActionWithTitle("Yes") { (TKAlert, TKAlertAction) -> Bool in
                return true
            action.backgroundColor = UIColor(red: 0.882, green: 0.882, blue: 0.882, alpha: 1.00)
            action.titleColor = UIColor(red: 0.302, green: 0.302, blue: 0.302, alpha: 1.00)
            action.cornerRadius = 3
            action = alert.addActionWithTitle("No") { (TKAlert, TKAlertAction) -> Bool in
                return true
            action.backgroundColor = UIColor(red: 0.961, green: 0.369, blue: 0.306, alpha: 1.00)
            action.titleColor = UIColor.whiteColor()
            action.cornerRadius = 3
        //MARK: - TKAlertDelegate
        func alertDidShow(alert: TKAlert) {
            print("apparently the alert is here")
            let view = TKView(frame: CGRectMake(20, -30, 60, 60))
            view.shape = TKPredefinedShape(type: TKShapeType.Circle, andSize: CGSizeZero)
            view.fill = TKSolidFill(color: UIColor(red: 0.961, green: 0.369, blue: 0.306, alpha: 1.00))
            //  view.fill =
            view.stroke = TKStroke(color: UIColor.whiteColor(), width: 3.0)
            view.transform = CGAffineTransformMakeScale(0.1, 0.1)
                delay: 0.0,
                usingSpringWithDamping: 0.3,
                initialSpringVelocity: 0.3,
                options: UIViewAnimationOptions.CurveEaseInOut,
                animations: { () -> Void in
                    view.transform = CGAffineTransformIdentity
                }) { (Bool) -> Void in }
