What is DetailModal? Is a property of your ViewController. I suggest you start it with a lower case for. I'd also rename ViewController to something more descriptive. — Ricardo Sanchez-Saez

The error is saying that the destination of your segue is a UIViewController rather than a ViewController. In your storyboard, make sure that the class for that controller is set to ViewController in the identity inspector.
