Using UIStoryboardSegue for purposes of injecting dependencies and passing data

BundleSegue.swift

class BundleSegue: ConfigurationSegue {

    typealias Source = BundlesViewController
    typealias Destination = BundleViewController

    typealias First = BundlesViewController
    typealias Second = BundleViewController

    override func inject() {
        destinationController.viewModel = resolver.resolve(BundleViewModelType.self)
    }

    override func propagate() {
        second.id = first.selectedID
    }

}

ConfigurationSegue.swift

import UIKit
import Swinject

class ConfigurationSegue: UIStoryboardSegue, InjectionSegueType, PropagationSegueType {

    typealias Source = UIViewController
    typealias Destination = UIViewController

    typealias First = UIViewController
    typealias Second = UIViewController

    func inject() {
    }

    func propagate() {
    }

    override func perform() {
        self.inject()
        self.propagate()

        super.perform()
    }

}

InjectionSegueType.swift

import UIKit
import Swinject

protocol InjectionSegueType {

    typealias Source: UIViewController
    typealias Destination: UIViewController

    var sourceController: Source { get }

    var destinationController: Destination { get }

    var resolver: Resolvable { get }

    func inject()

}

extension InjectionSegueType where Self: UIStoryboardSegue {

    var sourceController: Source {
        return sourceViewController as! Source
    }

    var destinationController: Destination {
        return destinationViewController as! Destination
    }

    var resolver: Resolvable {
        return assembler.resolver
    }

}

PropagationSegueType.swift

import UIKit

protocol PropagationSegueType {

    typealias First
    typealias Second

    var first: First { get }
    var second: Second { get }

    func propagate()

}

extension PropagationSegueType where Self: UIStoryboardSegue {

    var first: First {
        return sourceViewController as! First
    }

    var second: Second {
        return destinationViewController as! Second
    }

}
