Quick: How to Use

Just the basics to get started quickly.

Step A: Setup Project and Root VC

• create a SwiftUI project in Xcode (iOS is tested better)
• add the ViewController package,

e.g. via git@github.com:ZeeZide/ViewController.git

• create a new RootViewController, e.g. HomePage.swift:

```swift import ViewController

class HomePage: ViewController {

var view: some View { VStack { Text("Welcome to MWC!") .font(.title) .padding()

Spacer() } } } ```

• Instantiate that in the scene view, the ContentView.swift

generated by Xcode: ```swift import ViewController

struct ContentView: View { var body: some View { MainViewController(HomePage()) } } ```

• Compile and Run, should show the HomePage

Step B: Add a presented VC and navigate to it

• create a new ViewController, e.g. Settings.swift:

```swift import ViewController

class Settings: ViewController {

var view: some View { // the View being controlled VStack { Text("Welcome to Settings!") .font(.title) .padding()

Spacer() } } } ```

• Add an action to present the Settings from the HomePage:

```swift import ViewController

class HomePage: ViewController {

func configureApp() { show(Settings()) // or present(Settings()) }

var view: some View { VStack { Text("Welcome to MWC!") .font(.title) .padding()

Divider()

Button(action: self.configureApp) { Label("Configure", systemImage: "gear") }

Spacer() } } } ```

Pressing the button should show the settings in a sheet.

Step C: Add a NavigationController for Navigation :-)

• Wrap the HomePage in a NavigationController, in the scene view:

```swift import ViewController

struct ContentView: View { var body: some View { MainViewController(NavigationController(rootViewController: HomePage())) } } ```

Note pressing the button does a navigation. Things like this should also work:

func presentInSheet() {
  let vc = SettingsPage()
  vc.modalPresentationStyle = .sheet
  present(vc)
}

Adding a PushLink

The presentations so far make use of a hidden link. To explicitly inline a NavigationLink, use PushLink, which wraps that.

• Add a PushLink (until I get an NavigationLink init extension working)

to present the Settings from the HomePage: ```swift import ViewController

class HomePage: ViewController {

var view: some View { VStack { Text("Welcome to MWC!") .font(.title) .padding()

Divider()

PushLink("Open Settings", to: Settings())

Spacer() } } } ```

Who

ViewController is brought to you by ZeeZide. We like feedback, GitHub stars, cool contract work, presumably any form of praise you can think of.
