A step-by-step guide to building your first iOS app with SwiftUI — designed for both developers and designers exploring Vibe Coding.
Build and iterate on iOS apps conversationally using AI. Vibe Coding lets you describe what you want to create and see real SwiftUI code come to life instantly.
Vibe Coding is an AI-assisted development workflow that lets you build apps conversationally using natural language and real code. This guide walks you through building and running an iOS app using Xcode and then extending it through Vibe Coding, a conversational AI workflow that lets you generate, iterate, and refine SwiftUI apps using natural language.
No complex Swift knowledge required upfront — just follow along and start building!
- System Requirements
- Prerequisites
- 1. Getting Started
- 2. Build and Run Your App
- 3. Test Your App on a Real Device

- Troubleshooting
- Resources
- macOS: macOS 13.0 (Ventura) or later
- Xcode: Xcode 15 or later (tested with Xcode 15 - use latest stable for best experience)
- Storage: At least 15GB free space for Xcode and iOS components
- VS Code: Latest version
- GitHub Copilot: GitHub Copilot/Chat (may require subscription or sign-in depending on account)
Before you start, ensure you have:
- A Mac computer (MacBook, iMac, or Mac mini - required for iOS development)
- Apple ID signed into Mac App Store (for downloading Xcode)
- Internet connection for downloading Xcode components
- 15GB+ free storage for Xcode installation
- VS Code installed with GitHub Copilot extension
- GitHub account signed into Copilot (may require subscription)
In this section, you'll install Xcode and ensure your Mac is ready for SwiftUI development.
- Option A: Click this direct link: Download Xcode from Mac App Store
- Option B: Manually search in Mac App Store:
- Open the
Mac App Storeon your Mac - Search for
"Xcode"
- Open the
- Click
"Get"or"Install"to download Xcode (large download ~10-15 GB) - Click
"Open"to launch Xcode (as shown below)
- When Xcode opens for the first time, you'll see a component selection screen
- Make sure
iOS 26.0is selected (as shown below) - Also ensure
Predictive Code Completion Modelis selected for better coding experience - Click
"Download & Install"(this will download in the background) - Xcode will now download and install required components. (This may take several minutes.)
- Click
"Continue"when the welcome screen appears
| Component Selection | Continue Screen |
|---|---|
![]() |
![]() |
After clicking "Continue", you'll see the Xcode start screen:
- Click
"Create New Project..."to start building your iOS app
You'll now see the template selection screen:
- Make sure
"Multiplatform"is selected at the top (it should be by default) - In the Application section, click on
"App" - Click
"Next"to proceed
Now you'll set up your app's basic information:
- Product Name: Enter your app name (e.g., "Tic Tac Toe")
- Organization Identifier: Enter something like "com.yourname.tictactoe"
- Leave all other settings as default
- Click
"Next"to continue
Now you need to select where to save your project:
- Choose a location on your Mac (Desktop or Documents folder work well)
- Your project folder name will match your app name (e.g., "tic-tac-toe")
- Keep
"Create Git repository on my Mac"checked (this helps with version control) - Click
"Create"to finalize your project
Expected Result: Xcode workspace will show:
- Project structure on the left (Tic Tac Toe folder with
ContentView.swift) - Swift code editor in the center with syntax highlighting
- iOS Simulator preview on the right showing your app
- The default "Hello, world!" SwiftUI app is ready to be customized
🎉 Xcode Setup Complete! Your iOS project is ready - now let's move to VS Code! 🎉
Now let's open the project in VS Code and use AI to build your first iOS app - specifically a game app! We'll create a native SwiftUI Tic Tac Toe game:
- Open
Visual Studio Code - Go to
File > Open Folder(or pressCmd + O) - Navigate to your project folder (e.g., "tic-tac-toe")
- Select the project folder and click
"Open"
🎯 You're now ready to start building your iOS app using vibe coding!
Using VS Code Agent to build the Tic Tac Toe game
- Open GitHub Copilot Chat: Click on the GitHub Copilot Chat panel on the right side of VS Code, then select
"agent mode" - Enter the Prompt: Copy and paste this prompt in the chat:
Create a tic tac toe game using SwiftUI and Apple guidelines. Make it look like a native iOS app with proper design, animations, and user experience. Include game logic for two players, win detection, and score tracking.- Let the AI Work: The agent will analyze your project and start creating the Tic Tac Toe game
- Review and Accept: The agent will suggest changes to your Swift files - review and accept them
Now that you've set up your project and used Vibe Coding to generate your app code, let's see it in action!
In GitHub Copilot Agent mode, just ask:
Build and run my iOS app in the simulatorExpected Result: You should see your app launch in the iOS Simulator with your Tic Tac Toe game interface.
If there are errors, Copilot may suggest fixes for common build issues:
- Review suggested fixes before accepting
- Retry building after applying fixes
- Launch your app in the simulator
That's it! One command in Agent mode handles everything. 🚀
Once your app builds successfully in the simulator, you can also try it on a real iPhone or iPad to experience how it performs on device.
Want to see your app running on your actual iPhone or iPad? Here's how to set up and test on your physical device:
- Connect your iPhone or iPad to your Mac using a USB cable
- If prompted, tap "Trust This Computer" on your device
- Enter your device passcode when asked
If this is your first time running apps on your device:
- Go to Settings > Privacy & Security > Developer Mode on your device
- Toggle Developer Mode on
- Your device will restart
- After restart, confirm you want to enable Developer Mode
- Open your project in Xcode temporarily to set up device trust
- Select your device from the device selector (next to the play button)
- Click the play button to attempt a build
- On your device, go to Settings > General > VPN & Device Management
- Find your Apple ID under "Developer App" and tap it
- Tap "Trust [Your Apple ID]" and confirm
Once your device is set up and trusted, you can try asking GitHub Copilot:
Build and run my iOS app on my connected deviceor
Deploy this app to my iPhone/iPadIf Copilot can't deploy to device directly, you can always:
- Open the project in Xcode
- Select your device from the device selector
- Click the play button to build and run
🎯 Note: The device setup (trust, developer mode) only needs to be done once. After that, your device should be available as a build target.
💡 Tip: You can use your regular Apple ID for free device testing - no paid developer account is needed for basic builds.
If Provisioning Fails:
- Go to your project settings in Xcode
- Enable
"Automatically manage signing" - Ensure your Apple ID is added under
Xcode > Settings > Accounts - For detailed troubleshooting, see Apple's Code Signing Guide
Common Device Issues:
- Device not showing up in Xcode: Ensure it's unlocked and "Trust This Computer" is selected.
- Build fails due to provisioning: Go to your project settings and enable "Automatically manage signing."
Now that you've built and tested an app manually, let's see how Vibe Coding can help you generate and iterate faster with AI assistance.
💡 Ready to build your next idea? Here's how to start a new app from scratch using Vibe Coding.
Want to build something new? Here's how you can start from scratch using the same setup:
- Press ⇧ + ⌘ + N (Shift + Command + N) in Xcode, or go to File > New > Project
- You'll see the same template selection screen as before
- Make sure "Multiplatform" is selected at the top
- In the Application section, click on "App"
- Click "Next" to proceed
- Product Name: Enter your app name (e.g., "WeatherNow", "TaskMaster", "PhotoGallery")
- Organization Identifier: Enter something like "com.yourname.weathernow"
- Leave all other settings as default
- Click "Next" to continue
- Choose where to save your project (Desktop or Documents folder work well)
- Keep "Create Git repository on my Mac" checked
- Click "Create" to finalize your project
- Once the project is created, open its folder inside VS Code
- Follow the same steps as before: File > Open Folder and select your new project
Instead of the Tic-Tac-Toe example, describe what you want to build in plain English. Here's an example of a prompt you can give to GitHub Copilot or Vibe Coding:
Privacy Note: Avoid including API keys, passwords, or sensitive data in your prompts. Use placeholder values like
YOUR_API_KEYand configure real credentials through environment variables.
Create a native SwiftUI iOS weather app that uses the device's current location and the current time.
Use CoreLocation to request and read location permissions, fetch weather data from an HTTP API,
and display current conditions, temperature, hourly forecast for the next 24 hours, and simple daily summary.
Follow Apple Human Interface Guidelines: adaptive layout, Dark Mode, accessibility labels,
and smooth SwiftUI animations for transitions. Include basic error handling, a mockable networking layer,
and comments explaining key parts.- Once Copilot generates your code, review it in VS Code
- Run the app in Xcode Simulator to see your creation come to life
- Tweak your UI or logic interactively by asking for specific changes
💬 That's it - you just created a brand new SwiftUI app using your own natural-language prompt!
🎉 Congratulations! Your iOS app is now running. Ready to take your vibe coding skills to the next level?
💡 New to iOS Development? If this is your first SwiftUI project, you can test your app directly on an iOS Simulator without needing a physical device - perfect for learning and experimentation!
- Add interactive buttons: Ask Copilot to add buttons with custom actions
- Create navigation views: Build multi-screen apps with smooth transitions
- Implement animations: Add delightful micro-interactions to enhance user experience
- Try different prompts: Experiment with asking Copilot to add new features
