Creating a tutorial or welcome screen in SwiftUI is an effective way to guide new users through your app's features. In this article, we'll walk through the process of creating a simple tutorial screen using SwiftUI, similar to the tutorial screens Apple uses in their apps.

Step 1: Set Up Your SwiftUI Project

First, ensure you have a SwiftUI project set up. If not, create a new project in Xcode and choose SwiftUI as the user interface option.

Step 2: Create the Tutorial View

We will create a new SwiftUI view for the tutorial screen. This view will contain an image, some text, and a button to dismiss the tutorial.

1import SwiftUI
2
3struct TutorialSheet: View {
4    @Binding var showTutorial: Bool
5
6    var body: some View {
7        VStack {
8            Spacer()
9            
10            Image(systemName: "star.fill")
11                .resizable()
12                .aspectRatio(contentMode: .fit)
13                .frame(width: 100, height: 100)
14                .foregroundColor(.blue)
15                .padding()
16            
17            Text("Welcome!")
18                .font(.largeTitle)
19                .fontWeight(.bold)
20                .padding()
21
22            Text("Discover the amazing features of this app and learn how to use it effectively. Tap below to get started.")
23                .font(.body)
24                .multilineTextAlignment(.center)
25                .padding()
26
27            Spacer()
28            
29            Button(action: {
30                showTutorial = false
31            }) {
32                Text("Get Started")
33                    .font(.headline)
34                    .foregroundColor(.white)
35                    .padding()
36                    .frame(maxWidth: .infinity)
37                    .background(Color.blue)
38                    .cornerRadius(10)
39                    .padding(.horizontal)
40            }
41            
42            Spacer()
43        }
44    }
45}

In this example, @Binding var showTutorial: Bool is used to control the visibility of the tutorial screen.

Step 3: Display the Tutorial Screen

To display the tutorial screen, we need to present it as a sheet from the main content view of the app.

1import SwiftUI
2
3struct ContentView: View {
4    @State private var showTutorial = true
5
6    var body: some View {
7        VStack {
8            Text("Main App Content")
9                .padding()
10        }
11        .sheet(isPresented: $showTutorial) {
12            TutorialSheet(showTutorial: $showTutorial)
13        }
14    }
15}
16
17struct ContentView_Previews: PreviewProvider {
18    static var previews: some View {
19        ContentView()
20    }
21}

In ContentView, we use the sheet modifier to present the TutorialSheet when showTutorial is true.

In Closing

Creating a simple tutorial or welcome screen in SwiftUI is straightforward. By using a combination of VStack, Image, Text, and Button, you can guide your users through the essential features of your app and provide a smooth onboarding experience. This approach ensures that new users understand how to use your app effectively from the start!
