App Clips overview in iOS Swift

Introduction

App Clips let people use a small part of your app instantly without downloading the full app. This helps users quickly do a task without waiting.

When you want users to quickly order food without installing the full app.

When users need to pay for parking right away without searching for your app.

When someone wants to try a feature of your app from a website or QR code.

When you want to offer a fast way to join a loyalty program at a store.

When users need to scan a code and get instant access to a service.

Syntax

iOS Swift

import SwiftUI

@main
struct MyAppClip: App {
  var body: some Scene {
    WindowGroup {
      ContentView()
    }
  }
}

App Clips are small parts of your app that run instantly without full installation.

You create an App Clip target in Xcode and design a simple UI for quick tasks.

Examples

This is a simple view showing a welcome message in the App Clip.

iOS Swift

struct ContentView: View {
  var body: some View {
    Text("Welcome to My App Clip!")
      .padding()
  }
}

App Clips can start from links or NFC tags to open specific parts of your app.

iOS Swift

// App Clip can be launched from a URL or NFC tag
// Handle the URL to show relevant content

Sample App

This App Clip shows a simple screen with a title and a button to order coffee quickly. When the button is tapped, it prints a message in the console.

iOS Swift

import SwiftUI

@main
struct SimpleAppClip: App {
  var body: some Scene {
    WindowGroup {
      VStack {
        Text("Order Coffee Quickly")
          .font(.title)
          .padding()
        Button("Order Now") {
          print("Order placed!")
        }
        .padding()
        .background(Color.blue)
        .foregroundColor(.white)
        .cornerRadius(8)
      }
    }
  }
}

Important Notes

App Clips must be under 10 MB to load quickly.

Use simple UI and focus on one task for best user experience.

App Clips can be launched from QR codes, NFC tags, Safari banners, and Maps.

Summary

App Clips let users quickly access part of your app without full install.

They are great for fast tasks like ordering or paying.

Create App Clips with a simple UI and handle launch URLs or NFC triggers.
