ON-CAMPUS 🌟 SWIFT FOR BEGINNERS

This beginner-friendly, hands-on workshop is an introduction to Swift and iOS development. You’ll learn the fundamentals of Swift by building a fun, real app: an iPhone camera app that uses AI to ‘rate the vibe’ of a photo and share the results on a live leaderboard.

No prior iOS experience needed, this session focuses on learning Swift by doing.

What you’ll build
A simple iOS app written in Swift that takes a photo using the iPhone camera, sends the image to an AI model to generate a vibe score and a short, funny explanation, displays the result in the app UI and posts the score to a shared leaderboard visible to everyone in the room.

What you’ll learn (Swift-first)

• Swift basics: variables, functions, structs, and optionals
• How Swift apps are structured in Xcode
• Building simple screens with SwiftUI
• Handling user actions and app state
• Making your first network request from Swift
• Seeing how Swift code connects to real features like the camera and APIs

Provided before the workshop

• Starter Xcode project so you can focus on Swift, not setup
• Pre-built backend for the shared leaderboard
• Claude API key (active for a few days after the workshop)
• 5000 yen Apple gift card for the winner

What YOU need to prepare

• Bring a Mac with Xcode installed (download link). Please open Xcode after installation. Then tell it to install the iOS SDK.
• Bring an iPhone running iOS 18 or later, and a cable that connects your mac to your iPhone.
• Download Cursor and sign up for a free account – we’ll use this as a coding assistant during the workshop.
• Sign in to Xcode with your Apple ID account (the free account is fine; your app will just expire after 7 days) link if people do not already have an account
