I’ve recently started with dependancy injections in swift and i cant figure out how to pass a custom class while segueing to another Viewcontroller.

class Content {
    var title:String
    var about:String
    var location:String

    init(data: [String: Any]) {
        self.title = data["title"] as? String ?? ""
        self.about = data["about"] as? String ?? ""
        self.location = data["location"] as? String ?? "" 
    }
}

First Viewcontroller – Performing segue and passing necessary data.

func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
    performSegue(withIdentifier: "NextView", sender: self.allcontent[indexPath.item])
}

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "NextView" {
        let vc = segue.destination as! NextViewController
        let selectedRow = sender as? Content
            
        vc.content = selectedRow!
           
    }
}

Attempting to initiate NextViewcontroller with the passed custom class from the first ViewController.

class NextViewController: UIViewController {
    var content: Content
    
    init(content: Content) {
        self.content = content
    }

    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    // this way i can access properties from the custom class directly
    //content.title
    //content.about
}

I keep getting different warnings as i’m not sure on how to structure this correctly.

• ‘super.init’ isn’t called on all paths before returning from initializer
• ‘required’ initializer ‘init(coder:)’ must be provided by subclass of ‘UIViewController’

I’ve seen below code implemented in an example but i don’t understand what “coder” is or how its supposed to be used.

class EditUserViewController: UIViewController {
    var selectedUser: User

    init?(coder: NSCoder, selectedUser: User) {
        self.selectedUser = selectedUser
        super.init(coder: coder)
    }

    required init?(coder: NSCoder) {
        fatalError("You must create this view controller with a user.")
    }

    // ...
}

Any help or example would be appreciated.
