Coding Experience Challenge with AI - Season 2
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, we have 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, they 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
Build My First App with AI
Free · 30 minutes a day · 5 days
💡 In 5 days, you will have your own app.
It's okay if you don't know the first thing about coding. Just talk to the AI and an app will be created. Seriously.
🤔 Have you ever had thoughts like these?
"Should I try learning to code..."
"I want to make something with my iPad..."
"Do I need to know coding in the AI era?"
"I want to get a taste of it before joining a bootcamp"But when you actually try to start...
YouTube lectures → Give up after 30 minutes
Inflearn courses → Pay but never watch
Books → Can't even get past Chapter 1The problem is that "you don't end up with an app on the very first day."
Printing print("Hello World")
learning variables
learning conditional statements...
"Why am I learning this?"
"When do we actually make the app?"
→ Giving up
💡 So, I changed the order.
The traditional way
print("Hello World") "AI, make an app for me"
1 week later: Learning variables
After 1 day: My app is created
1 month later: Still no app
Challenge
After 5 days: Even app modification
Result: Giving up 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 / What to do / Experience / Time
Ordering an app from AI "Real code actually appeared!" 30 min
Running my app "Wow, it actually works!" 40 minutes
Try modifying the app "It changes when I speak!" 35 minutes
Exploring the code "I see the patterns" 35 min
Reflection + Decision "Is this right for me?" 30 min
All it takes is 30 minutes a day.
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 monthsSmall promises, certain fulfillment.
No exaggerations.
🙋 This is perfect for you if:
✅ Join now
Those who have only thought, "Should I try coding?"
Those who started a coding course but gave up.
Those who only use their iPads to watch YouTube
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 a basic understanding of coding
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 won
No extra cost.
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 panicked because of an error, but I asked the AI and it fixed it right away. This actually works?"
"The code still looks like a foreign language, but on Day 4, I started to see patterns."
"In just 5 days, I felt like 'I can do this too.' It made me want to learn more."
📋 How it works

100% enrolledIt was a practice-oriented lecture where I could naturally understand the flow of code by creating an app with AI and directly running and modifying a schedule management app. Through solving missions and receiving feedback, I gained motivation and had a meaningful experience that gave me the confidence that "I can do it too" in a short period of time.

FAQs
Yes. In fact, a blank slate is better.
Because there are no bad habits.
If you have a MacBook, there is also Swift Playgrounds for Mac.
iPad is recommended, but not required.
That's why we start with the app.
If you have "your own app" from day one, you'll want to see it through to the end.
And we move forward together with weekly feedback.
With Python, it's hard to see "results." Only text appears in the terminal.
With Swift Playgrounds, you can see the "app" immediately.
Visible results create motivation.
