With

SegueManager

segueManager.performSegue(withIdentifier: "showDetails") { (details: DetailsViewController) in
  details.viewModel = DetailsViewModel("This is the details view model")
}

See the full iOS example, or read below for usage instructions.

Typed segues with R.swift

A major design goal of SegueManager 2.0 is to allow completely statically typed segues using

R.swift

With R.swift the above example becomes:

self.performSegue(withIdentifier: R.segue.masterViewController.showDetails) { segue in
  segue.destination.viewModel = DetailsViewModel("This is the details view model")
}

Here the

segue

TypedStoryboardSegueInfo

.destination

To use R.swift together with SegueManager, include this subspec to your Podfile:

pod 'SegueManager/R.swift'

Installation

CocoaPods

SegueManager is available for both iOS and OS X. Using CocoaPods, SegueManager can be integrated into your Xcode project by specifying it in your

Podfile

pod 'SegueManager'

Then, run the following command:

$ pod install

Usage

There are two methods of using SegueManager:

1. Inherit from one of the base types:

   SegueManagerViewController

   ,

   SegueManagerTableViewController

   ,

   SegueManagerCollectionViewController

   , etc.

2. Or, if you don't want to rely on inheritance (often problematic), create a SegueManager yourself:

   1. On your ViewController, create a

      SegueManager

      , instantiated with

      self

      .
   2. Implement the

      SeguePerformer

      protocol
   3. Override

      prepare(for:)

      and call SegueManager.

import SegueManager

class MasterViewController: UIViewController, SeguePerformer {
  lazy var segueManager: SegueManager = {
    // SegueManager based on the current view controller
    return SegueManager(viewController: self)
  }()
  override func prepare(for segue: UIStoryboardSegue, sender: AnyObject?) {
    segueManager.prepare(for: segue)
  }
}

After this setup, simply call

performSegue

With SegueManager only

Call

performSegue(withIdentifier)

self.performSegue(withIdentifier: "showDetails") { (details: DetailsViewController) in
  details.viewModel = DetailsViewModel("This is the details view model")
}

With SegueManager + R.swift

Call

performSegue(withIdentifier)

R.segue.*

self.performSegue(withIdentifier: R.segue.masterViewController.showDetails) { segue in
  segue.destination.viewModel = DetailsViewModel("This is the details view model")
}

The handler will be called after the destination view controller has been instantiated, but before its view has been loaded or any animations start.
