Part0: Learning Swift6 for Complete Beginners Through Problem Solving (Free, 2025, Perfect XCode 26 Support)

Hello, I'm agmma, a professional iOS developer

I started studying development at 31 while doing other work, and now I'm diligently working as an iOS developer at a subsidiary of one of the major Korean tech companies (NAVER, Kakao, LINE, Coupang).

• Started studying development at a bootcamp in early 2020 (age 31)

• At the end of 2021 (age 33), got a junior iOS developer position at a subsidiary of one of the major Korean tech companies (Naver, Kakao, LINE, Coupang)

• As of 2025, still working at the same company

As someone who started development at the late age of 30s as a non-major, I deeply empathize with the uncertainty and difficulties that job seekers face more than anyone else. I also understand well the efforts of those who are preparing for career transitions by dedicating their precious time to continuous growth.

Having spent two years without any income, running solely toward my dream of becoming a developer, I want to provide high-quality courses at reasonable prices to those walking a similar path.

Although not all curriculum has been completed yet, when all the lectures I've planned are released, if you consistently follow my lectures, you'll be able to acquire all the knowledge needed for a 1-2 year iOS developer, and I will create them with that sense of responsibility.

📖 eBook Preview

The image shown below is a capture of some content from the free e-book that will be provided with this course.
Since it contains the exact same material used in the actual lectures, students can review following the same flow as the course.

This e-book is not just a simple text summary.

• Key Concepts Summary: Systematically organized essential content from the lectures that you must remember

• Various Example Codes: Includes code samples that you can follow along with to broaden your understanding

• Visual Materials and Diagrams: Schematized to make even abstract concepts easy to understand

• Practice Problems: Check your understanding and enable self-directed learning

Therefore, the e-book is not just reading material, but a supplementary textbook that allows you to practice and review alongside the lectures to maximize learning effectiveness.

Through this free e-book, even those just starting development will be able to learn Swift and iOS more deeply and systematically.

📝 Learn More Effectively with Problem-Based Learning!

Programming language courses can easily feel stiff and boring.
That's why this course doesn't just stop at explaining concepts, but includes practice problems for each concept so you can think through and solve them yourself.

💡 Simply watching lectures and learning concepts means they just pass through your mind and are easily forgotten.
However, by solving practice problems, you can check what you just learned on your own and experience making the knowledge truly yours.

Additionally, the problems are not simple memorization-based, but include scenario-based problems linked to actual Swift code, designed to naturally develop practical coding skills.
In other words, through the lecture → problem → solution process, you can complete the learning cycle of concept understanding → application → self-assessment.

The photos shown below are actual examples of quiz questions included in the course.
By solving these problems, you won't just be a "passive learner," but rather an actively participating and growing developer. 🚀

💻 Perfect Xcode 26 Support

This course "(Free) Learn Swift by Solving Problems (2025, Perfectly Compatible with XCode 26)" was created with perfect compatibility for Xcode 26, the latest version as of August 2025. 🚀
Therefore, all example code and practice materials covered in the course work properly in the Xcode 26 environment.

Currently, Xcode 26 is available as a beta version, and to use it, you'll need the latest beta version of macOS, macOS Tahoe. 🍎
Therefore, if you want to experience the latest technology as quickly as possible, you can follow along with the course content in the beta environment.

However, since the official version has not been released yet, you don't need to worry.
👉 There is no problem at all taking the course in the existing Xcode 15 environment, and you can learn all the code and concepts without any issues.

In other words, this course has the following advantages:

• ✅ Fully compatible with the latest version (Xcode 26) → Experience the latest development environment

• ✅ Compatible with existing version (Xcode 15) → Can learn in a stable environment

• ✅ Created with future updates in mind → Can be used as-is even after the official version release

📌 In conclusion, this course is the fastest way to learn Swift and iOS development in line with the latest trends.
"A course that allows hands-on practice even in the latest beta environment while being perfectly followable in stable existing versions" — This is precisely the greatest strength of this course. 🌟

🚀 8 hours 43 minutes, free but better than paid quality lectures
