### Setup UIOnboarding Helper Components

Source: https://github.com/lascic/uionboarding/blob/main/README.md

Provides helper functions to configure various components of the UIOnboarding view, including app icon, title lines, features, notice text, and button configuration.

```swift
import UIKit
import UIOnboarding

struct UIOnboardingHelper {
    // App Icon
    static func setUpIcon() -> UIImage {
        return Bundle.main.appIcon ?? .init(named: "onboarding-icon")!
    }

    // First Title Line
    // Welcome Text
    static func setUpFirstTitleLine() -> NSMutableAttributedString {
        .init(string: "Welcome to", attributes: [.foregroundColor: UIColor.label])
    }
    
    // Second Title Line
    // App Name
    static func setUpSecondTitleLine() -> NSMutableAttributedString {
        .init(string: Bundle.main.displayName ?? "Insignia", attributes: [
            .foregroundColor: UIColor.init(named: "camou")!
        ])
    }

    // Core Features
    static func setUpFeatures() -> Array<UIOnboardingFeature> {
        return .init([
            .init(icon: .init(named: "feature-1")!,
                  title: "Search until found",
                  description: "Over a hundred insignia of the Swiss Armed Forces – each redesigned from the ground up."),
            .init(icon: .init(named: "feature-2")!,
                  title: "Enlist prepared",
                  description: "Practice with the app and pass the rank test on the first run."),
            .init(icon: .init(named: "feature-3")!,
                  title: "#teamarmee",
                  description: "Add name tags of your comrades or cadre. Insignia automatically keeps every name tag you create in iCloud.")
        ])
    }

    // Notice Text
    static func setUpNotice() -> UIOnboardingTextViewConfiguration {
        return .init(icon: .init(named: "onboarding-notice-icon")!,
                     text: "Developed and designed for members of the Swiss Armed Forces.",
                     linkTitle: "Learn more...",
                     link: "https://www.lukmanascic.ch/portfolio/insignia",
                     linkColor: .init(named: "camou"))
    }

    // Continuation Title
    static func setUpButton() -> UIOnboardingButtonConfiguration {
        return .init(title: "Continue",
                     titleColor: .white, // Optional, `.white` by default
                     backgroundColor: .init(named: "camou")!)
    }
}

```

--------------------------------

### Add UIOnboarding Package

Source: https://github.com/lascic/uionboarding/blob/main/README.md

Use Swift Package Manager to add the UIOnboarding library to your Xcode project. Specify the version or branch for installation.

```swift
.package(url: "https://github.com/lascic/UIOnboarding.git", from: "2.0.0")
```

```swift
.package(url: "https://github.com/lascic/UIOnboarding.git", branch: "main")
```

--------------------------------

### Set Up UIOnboardingViewConfiguration

Source: https://github.com/lascic/uionboarding/blob/main/README.md

Creates a complete UIOnboardingViewConfiguration object using the helper functions. This configuration is used to initialize the onboarding view controller.

```swift
import UIOnboarding

extension UIOnboardingViewConfiguration {
    // UIOnboardingViewController init
    static func setUp() -> UIOnboardingViewConfiguration {
        return .init(appIcon: UIOnboardingHelper.setUpIcon(),
                     firstTitleLine: UIOnboardingHelper.setUpFirstTitleLine(),
                     secondTitleLine: UIOnboardingHelper.setUpSecondTitleLine(),
                     features: UIOnboardingHelper.setUpFeatures(),
                     textViewConfiguration: UIOnboardingHelper.setUpNotice(),
                     buttonConfiguration: UIOnboardingHelper.setUpButton())
    }
}

```

--------------------------------

### Configure Localized Welcome Title

Source: https://github.com/lascic/uionboarding/blob/main/README.md

Demonstrates how to set up a single-line welcome title by providing an empty attributed string for the second title line. The UIOnboardingTitleLabelStack adjusts automatically.

```swift
// First Title Line
// App Name
static func setUpFirstTitleLine() -> NSMutableAttributedString {
    return .init(string: Bundle.main.displayName ?? "Distintivos", attributes: [
            .foregroundColor: UIColor.init(named: "camou")!
    ])
}

// Second Title Line
// Empty
static func setUpSecondTitleLine() -> NSMutableAttributedString {
    return .init(string: "")
}

```

--------------------------------

### SwiftUI OnboardingView Implementation

Source: https://github.com/lascic/uionboarding/blob/main/README.md

Implement the UIViewControllerRepresentable protocol to create a SwiftUI view for UIOnboardingViewController. Assign the coordinator as the delegate.

```swift
// In OnboardingView.swift
import SwiftUI
import UIOnboarding

struct OnboardingView: UIViewControllerRepresentable {
    typealias UIViewControllerType = UIOnboardingViewController

    func makeUIViewController(context: Context) -> UIOnboardingViewController {
        let onboardingController: UIOnboardingViewController = .init(withConfiguration: .setUp())
        onboardingController.delegate = context.coordinator
        return onboardingController
    }
    
    func updateUIViewController(_ uiViewController: UIOnboardingViewController, context: Context) {}
    
    class Coordinator: NSObject, UIOnboardingViewControllerDelegate {
        func didFinishOnboarding(onboardingViewController: UIOnboardingViewController) {
            onboardingViewController.dismiss(animated: true, completion: nil)
        }
    }

    func makeCoordinator() -> Coordinator {
        return .init()
    }
}
```

--------------------------------

### Conditionally Show Onboarding

Source: https://github.com/lascic/uionboarding/blob/main/README.md

Checks a UserDefaults flag to determine if the onboarding has been completed. If not, it calls a function to display the onboarding screen.

```swift
if !UserDefaults.standard.bool(forKey: "hasCompletedOnboarding") {
    showOnboarding()
}

```

--------------------------------

### Handle Onboarding Completion

Source: https://github.com/lascic/uionboarding/blob/main/README.md

Dismisses the onboarding view controller with a cross-dissolve transition and sets a UserDefaults flag to indicate that onboarding is complete.

```swift
func didFinishOnboarding(onboardingViewController: OnboardingViewController) {
    onboardingViewController.modalTransitionStyle = .crossDissolve
    onboardingViewController.dismiss(animated: true) { 
        UserDefaults.standard.set(true, forKey: "hasCompletedOnboarding")
    }
}

```

--------------------------------

### SwiftUI ContentView with Onboarding Trigger

Source: https://github.com/lascic/uionboarding/blob/main/README.md

A SwiftUI ContentView that uses a button to trigger the presentation of the OnboardingView via a .fullScreenCover modifier.

```swift
// In ContentView.swift
import SwiftUI

struct ContentView: View {
    @State private var showingOnboarding = true
    
    var body: some View {
        NavigationView {
            Text("Hello, UIOnboarding!")
                .toolbar {
                    Button {
                        showingOnboarding = true
                    } label: {
                        Image(systemName: "repeat")
                    }
                }
                .fullScreenCover(isPresented: $showingOnboarding, content: {
                    OnboardingView.init()
                        .edgesIgnoringSafeArea(.all)
                })
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView.init()
    }
}
```

--------------------------------

### Present UIOnboarding in UIKit

Source: https://github.com/lascic/uionboarding/blob/main/README.md

Present the UIOnboardingViewController from a UIKit view controller. Ensure the presenting view controller is embedded in a UINavigationController.

```swift
import UIKit
import UIOnboarding

let onboardingController: UIOnboardingViewController = .init(withConfiguration: .setUp())
onboardingController.delegate = self
navigationController?.present(onboardingController, animated: false)
```

--------------------------------

### Present UIOnboarding in SwiftUI

Source: https://github.com/lascic/uionboarding/blob/main/README.md

Use the .fullScreenCover modifier to present the OnboardingView in a SwiftUI application. This requires wrapping the UIOnboardingViewController using UIViewControllerRepresentable.

```swift
.fullScreenCover(isPresented: $showingOnboarding, content: {
    OnboardingView.init()
        .edgesIgnoringSafeArea(.all)
}
```

--------------------------------

### Dismiss UIOnboarding in UIKit

Source: https://github.com/lascic/uionboarding/blob/main/README.md

Implement the UIOnboardingViewControllerDelegate method to dismiss the onboarding view controller. This is typically called when the user completes the onboarding process.

```swift
extension ViewController: UIOnboardingViewControllerDelegate {
    func didFinishOnboarding(onboardingViewController: UIOnboardingViewController) {
        onboardingViewController.modalTransitionStyle = .crossDissolve
        onboardingViewController.dismiss(animated: true, completion: nil)
    }
}
```
