This is an example project which demonstrates the usage of CoreNavigation's view controller data passing capabilities.

Medium posts:

• #2 - Passing data between view controllers.
• #3 - Handle Universal Links Like a Boss.

Installation

Clone CoreNavigation repo and:

$ cd Examples/PassingDataExample
$ pod install

Use case

• App has one view controller ColorViewController which:
  • can receive UIColor as a data
  • has color picker which triggers navigation to same view controller type and passes chosen color as data to the new instance

Demo

Code

View controller:

import UIKit
import CoreNavigation
import ChromaColorPicker

class ColorViewController: UIViewController {
    ...
}


// MARK: DataReceivable
extension ColorViewController: DataReceivable {
    typealias DataType = UIColor

    func didReceiveData(_ data: UIColor) {
        view.backgroundColor = data
    }
}

// MARK: ChromaColorPickerDelegate
extension ColorViewController: ChromaColorPickerDelegate {
    func colorPickerDidChooseColor(_ colorPicker: ChromaColorPicker, color: UIColor) {
        Navigate.push { $0
            .to(Color())
            .passData(color)
        }
    }
}

Destination:

import Foundation
import CoreNavigation

struct Color: Destination {
    typealias ViewControllerType = ColorViewController
}
