Creating Workflows in UIKit

Step 1

To create workflows in UIKit, start with a UIViewController that should be part of a Workflow, then modify it to be FlowRepresentable.


import UIKit
import SwiftCurrent
import SwiftCurrent_UIKit

// This screen shows an employee only screen
class FirstViewController: UIWorkflowItem<String, String>, FlowRepresentable { // SwiftCurrent
    private let email: String
    private let finishButton = UIButton()

    required init(with email: String) { // SwiftCurrent = email
        super.init(nibName: nil, bundle: nil)
        // Configure your view programmatically or look at StoryboardLoadable to use storyboards.

    required init?(coder: NSCoder) { nil }

    @objc private func finishPressed() {
        proceedInWorkflow(email) // SwiftCurrent

Note: Call FlowRepresentable.proceedInWorkflow() to have your view move forward to the next item in the Workflow it is part of.

Step 2

Define your Workflow and launch it. This is what allows you to configure or reorder your workflow.


// From the ViewController you'd like to launch the workflow
@objc private func didTapLaunchWorkflow() {
    let workflow = Workflow(FirstViewController.self) // SwiftCurrent
        .thenPresent(SecondViewController.self) // SwiftCurrent

    launchInto(workflow, args: "Some starting arguments")
