Coding Experience Challenge with AI - Phase 3

And now we are in the era of AI. In the past, "app first" was difficult. Someone had to give you the code. You had to copy it from a book or find it on the internet. But now, there is AI. If you say "make me an app," actual app code comes out. This is a complete game changer. Now, anyone can have an app from day one. And while looking at that app, you can ask, "What is this?" The method I used 10 years ago is now something anyone can do.

Hello, I'm Leeio, a developer fishing for code in Pohang.

Co-instructor

5-Day Coding Experience Challenge

Making My First App with AI

Free · 30 minutes a day · 5 days


💡 In 5 days, you will have your own app.

It's okay even if you don't know the first thing about coding. Just talk to the AI and an app will be created. It's for real.


🤔 Have you ever had these thoughts?

"Should I try learning to code..." "I want to try making something with my iPad..." "Do I need to know coding in the AI era?" "I want to get a taste of it before going to a bootcamp"

But when you actually try to start...

YouTube lectures → Give up after 30 minutes Inflearn courses → Pay for them but never watch Books → Can't even get past Chapter 1

The problem is that 'you don't get an app from day one.'

print("Hello World"), learning variables, learning conditional statements... "Why am I learning this?" "When do we actually make the app?" → Give up → Bỏ cuộc

💡 So, I changed the order.

Traditional Method:

  • After 1 day: Learning variables

  • After 1 week: I have my own app

  • 1 month later: Still no app

  • Result: Giving up or no sense of efficacy


Challenge:

  • After 1 day: Tried writing code

  • 3 days later: App maintenance

  • After 5 days: Gain app development experience

  • Result : "I can do it too!"

When you have an app from the very first day,
you understand why you're learning.
When you know why you're learning, you can keep going.


📅 This is what we'll do for 5 days

  • Day 1 : Ordering an app from AI - "Real code actually came out!"(30 min)

  • Day 2 : Running my app - "Wow, it works!"(40 min)

  • Day 3 : Try modifying the app - "It changes as I speak!"(35 min)

  • Day 4 : Looking at the Code - "I see the pattern" (35 min)

  • Day 5 : Retrospective + Decision - "Is this right for me?"(30 mins)


30 minutes a day is all it takes.
You can even do it on your subway commute.


🎯 In 5 days, you will have

✅ This is what you'll get

✅ Your own app (one that actually runs) ✅ Knowing what code looks like ✅ A list of "What is this?" questions ✅ A sense of whether coding is right for you ✅ Direction on what to do next

❌ I don't promise this

❌ Coding Master ❌ Getting a job as a developer ❌ App Store launch ❌ 50 million won salary in 6 months

Small promises, certain fulfillment.
No exaggerations.


🙋 This is perfect for you if:

✅ Join us

  • Those who have only thought, "Should I try coding?"

  • Those who started a coding course but gave up

  • Those who only watch YouTube on their iPads

  • Those who are wondering if they need to know coding in the AI era

  • Those who want a taste of it before joining a bootcamp

❌ Not a good fit

  • Those who already have basic coding knowledge

  • Those who don't even have 30 minutes a day

  • Those who do not have an iPad or Mac


🛠 Requirements

Requirements: iPad or Mac (to run the app), Swift Playgrounds app, Claude AI account (claude.ai)

Cost: 0 KRW

No extra costs.
Start with the devices you already have.


💬 This is the kind of experience you'll have

"Real code came out on Day 1. I just talked to the AI, and it happened. It was amazing."

"I got goosebumps when the app ran on Day 2. It's my app!"

"I was flustered because of an error, but when I asked the AI, it fixed it right away. This actually works?"

"The code still looks like a foreign language, but I started to see patterns on Day 4."

"In just 5 days, I felt like 'I can do this too.' It made me want to learn more."


📋 How it works

This is how we do it every day

1️⃣ Check today's content (5-10 mins) → Guidance on what to learn via video or text 2️⃣ Hands-on practice (15-25 mins) → Follow along step by step 3️⃣ Mission complete (5 mins) → Check off today's tasks 4️⃣ Verification (5 mins) → Screenshot + one-line reflection → Share on the Slack channel

Elements of working together

💬 Slack Community → Questions, encouragement, sharing 📸 Daily Verification Channel → Get motivated by seeing each other's progress ❓ Question Channel → Ask immediately if you get stuck 📢 Reminders → Daily morning/evening notifications

    I consider the instructor's voice tone important when choosing a lecture, and the content is easy to understand with a calm, honey-like voice. It is well-made so that even someone who knows absolutely nothing about AI, Swift, or Playground can follow along step-by-step! Once the challenge is over, I'm planning to buy a paid AI tool. I'm currently debating which one to get~ <Course Completion Review> I'm the type of person who isn't very good at finishing things. However, the Leeio Challenge uses friendly expressions even for someone completely new to development, so I was able to complete the course without losing confidence!! Want to get a taste of vibe coding? Lacking confidence in development right now? Not sure how to study? Just want to do something fun!! I recommend this to anyone feeling this way.
