How to Start a SwiftUI App in 2025

Starting a SwiftUI app in 2025 means embracing the latest Swift and Apple technologies to build modern, fast, and maintainable iOS applications. Whether you’re a beginner or updating your skills, here’s a step-by-step guide to get your SwiftUI app up and running.

Step 1: Set Up Your Development Environment

• Install the latest version of Xcode from the Mac App Store (Xcode 15 or newer).
• Make sure your macOS is updated to support the latest Xcode.
• Familiarize yourself with the Swift 5.9+ language features introduced recently.

Step 2: Create a New SwiftUI Project

• Open Xcode and choose "Create a new Xcode project."
• Select "App" under the iOS tab.
• Name your project (e.g., SwiftShelfApp).
• Ensure "Swift" is selected as the language and "SwiftUI" as the interface.

Step 3: Understand the App Structure

• The main entry point is marked with the @main attribute.
• Your ContentView.swift uses SwiftUI’s declarative syntax.
• Learn the basic building blocks like View, State, Binding, and ObservableObject.

Step 4: Build Your First View

Start by modifying ContentView.swift:

import SwiftUI

struct ContentView: View {
    @State private var counter = 0

    var body: some View {
        VStack(spacing: 20) {
            Text("Welcome to SwiftShelf!")
                .font(.title)
                .padding()
            Text("You’ve tapped \(counter) times")
                .font(.headline)
            Button("Tap Me") {
                counter += 1
            }
            .buttonStyle(.borderedProminent)
        }
        .padding()
    }
}

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

Step 5: Run Your App

Press Cmd+R to build and run your app in the iOS Simulator.

Interact with the button to see your app respond.

Step 6: Explore Further

Experiment with lists, navigation, and data flow.

Learn about Combine framework for reactive programming.

Follow Apple’s official SwiftUI tutorials and documentation.

By starting with these steps, you’ll build a solid foundation for SwiftUI development in 2025 and beyond. Keep coding and exploring new features as Apple updates the ecosystem!

Happy coding! 🚀
