Custom init for UIViewController in Swift with interface setup in storyboard

Question

I\'m having issue for writing custom init for subclass of UIViewController, basically I want to pass the dependency through the init method for viewController rather than se

You can't use a custom initializer when you initialize from a Storyboard, using init?(coder aDecoder: NSCoder) is how Apple designed the storyboard to initialize a controller. However, there are ways to send data to a UIViewController.

Your view controller's name has detail in it, so I suppose that you get there from a different controller. In this case you can use the prepareForSegue method to send data to the detail (This is Swift 3):

override func prepare(for segue: UIStoryboardSegue, sender: AnyObject?) {
    if segue.identifier == "identifier" {
        if let controller = segue.destinationViewController as? MemeDetailVC {
            controller.meme = "Meme"
        }
    }
}

I just used a property of type String instead of Meme for testing purposes. Also, make sure that you pass in the correct segue identifier ("identifier" was just a placeholder).
