Allen Swift Grammar Master School✍🏻📚

🌿🌿🌿

The reason developers fail to get hired or don't grow into good developers
is not because they lack advanced knowledge,
but because their foundational knowledge is not solid.

Not vague concepts,
(and not just roughly knowing how to code)
but having clear understanding and solid foundational concepts
is what I believe enables long-term growth into a good developer..

Following that belief and conviction
to create educational materials where you can truly "learn properly" about Swift
I dedicated a full year to creating lecture materials
and prepared this course.

🌿🌿🌿

Hello, I'm Allen.

This is the Swift Grammar + iOS App Development Course that I've ambitiously prepared. It took me a full 1 year and 6 months just to prepare and launch this course.

The classes are provided online on Inflearn, (so you can watch the online lectures anytime), but they are operated in a 2-month online bootcamp format (Zoom classes once a week).

• CS(Computer Science)
• (Advanced Level)Swift Grammar
• Creating 15 basic apps while learning the fundamental UIKit framework
  (Understanding the basic principles of how apps are built)
  
• Swift Concurrency - Concurrent Programming for Swift 6 (Additional Provided Lecture)

The reason we decided to open it as an online bootcamp format is because the course price is a bit high, and based on our experience with online courses so far, there's the disadvantage of difficulty in providing real-time feedback... Having seen cases where people waste time with a lot of trial and error during the early stages of preparing for a developer job, we wanted to help resolve these issues.

During the most important early period, in preparing to become an "iOS developer"... this is the conclusion we reached after much consideration to minimize your trial and error. If you can quickly solve the problems you encounter early on and clearly understand the concepts before moving forward...we're confident that you can save at least 4-5 months of time.

The decision was made to resolve questions quickly through Slack, and when necessary, to take and resolve questions via Zoom.

• Watch lectures 3 hours each on weekdays, 3-4 times per week (minimum 15 hours of study per week / minimum progress required)
• Monday evening (9 PM) or Tuesday evening (9 PM) Zoom sessions for simple tests / Q&A / lecture review
• Occasionally planning to conduct sessions by inviting current iOS developers
  
  
  

The main content of this course is Swift syntax, and it aims to take complete beginners who have absolutely no coding knowledge and are just starting to study coding, and bring them up to an advanced level of Swift syntax. (Therefore, it's perfectly fine for computer science majors or working professionals who want to understand Swift syntax in depth to take this course as well. In the latter part, there will be really deep content, and concepts that you previously found confusing will be clearly organized in your mind.)

The reason I prepared this course is,
because of my philosophy that it is absolutely impossible to grow into a good developer without a proper grammar foundation (and without understanding how CPU and RAM work). My courseaims to have knowledge at the level of 2-3 year developers who have joined top-tier companies like Naver, Kakao, Line, Coupang, and Baemin, at least when it comes to Swift grammar. (If you've seen my iOS Concurrency Programming course, you'll know that I like concepts that can be clearly expressed through diagrams... those thoroughly intuitive and clear concepts. I thoroughly reject vague and ambiguous concepts.)

And on this solid foundation of thoroughly refined grammar, by creating 15 basic apps, you'll be able to understand the very principles of how apps are built. (Unlike other existing courses, I absolutely do not pursue a "follow-along coding" style of teaching.) Those who understand the relationship between grammar and basic frameworks, and the principles behind how apps are created based on this, will not only be able to apply this knowledge on their own, but will also reach a level where they can sufficiently self-study independently. I've experienced these aspects through multiple tutoring sessions.
(This means that grasping the fundamentals and principles is the most important thing.)

Since I started coding as a non-major through a bootcamp, I experienced firsthand what parts academies don't teach well, what trial and error you go through... and what understanding of CS is necessary. Because of this direct experience, all those aspects I studied through trial and error are incorporated into the course.

And since I've taken every course available, both domestic and international, including Raywenderlich / Udemy and others... I can confidently say that when it comes to Swift syntax, there is nowhere else on Earth that teaches Swift syntax in more detail and with easier explanations using better organized materials than this.

(If there's any place including academies/bootcamps that teaches Swift grammar with high-level content while explaining it more easily than my lectures, please let me know. I will refund the tuition fee for that person who informs me.)

My Teaching Philosophy and Direction 🔭💎

This is not a simple grammar lecture. I've watched dozens of WWDC sessions, Swift international forums, Raywenderlich, and other sources that cover content not even described in the official Swift documentation - such as Swift's internal memory implementation structure - and I've organized all this content in my own way using diagrams.

Why do I think this is important? For example, if you understand the memory structure of inheritance in classes through diagrams, there's nothing you need to memorize. Why stored properties cannot be overridden during inheritance, why computed properties can be overridden, why methods can be overridden, why initializers are not automatically inherited, why methods implemented in extensions cannot be overridden, etc... I used to forget these detailed rules every time even after reading them dozens of times when I was studying before, but when you understand these concepts through Swift's internal implementation memory structure, you don't need to memorize them - they just become obvious.

Why structs are inevitably faster than classes, why struct usage is generally recommended over classes (when inheritance structure is not needed)... Rather than simply memorizing this, I'll explain the unavoidable reasons through CPU/memory operating principles.
(Actually, these aspects are quite difficult for non-CS majors to understand without considerable study.)

Going beyond simple grammatical content, I'll intuitively explain what protocol-oriented programming is, what functional programming is, when to use protocols, and the reasons for using each grammar topic and the background behind how such grammar came to exist.

I absolutely believe that just memorizing without understanding is meaningless. I also started as a non-CS major, learned at an academy, watched other Swift lectures 3-4 times or more, read other Swift books 5+ times... and my conclusion was just memorization. I also watched almost all intermediate/advanced Swift grammar courses on Raywenderlich/Udemy, and naturally read the Swift official documentation multiple times. But even after watching grammar content dozens of times like this... I used to forget everything. The human brain inevitably has limitations when it comes to memorization. But as I mentioned above, until I understood the internal structure, I thought I just had to memorize everything like this. However, as I continued studying... not just Swift, but the background of how the concept of classes came to exist in programming... and the overall (computer science) memory structure behind why all languages support inheritance in classes... after extensively researching and studying this... (of course, there are detailed differences in the directions each language pursues...) anyway, the parts I had to memorize disappeared. When you understand the operating principles and structure of a method, there's no need to memorize it.

I'll teach you content like this. As far as I know, there are no such lectures in Korea. Including other languages like Python, Java, etc., there are absolutely no lectures that explain grammar in connection with CPU operations and memory structure like this. I plan to make all this content "your own" knowledge through easy diagram explanations. (If you study this way, not only will all other languages become easier, but you'll understand how computers operate and their structure itself, enabling you to easily apply anything and intuitively solve any problem.)

I can confidently say that this lecture will change your starting point and approach to development studies, and if you're a non-CS major, the skill gap between those who have taken this lecture and those who haven't will be truly enormous. What I struggled with countless times, you'll gain tremendously in just 2 months.

Through this opportunity, for those just starting iOS studies, this will be like a ray of light... and for those who have experienced several struggles before, this will be a higher-dimensional lecture with intuitive explanations that are easy to understand...I will do my best to help you grow as an iOS developer.

After taking this class, in 2 months you will be 📚📊

Even if you're just starting to study now, in 2 months you'll naturally be able to read articles at this level and understand them as if it's obvious.
(The blog above is not my blog. It's an article organized by someone called 'Zedd' about what Apple announced at WWDC2016. It's content where Apple presents how to improve Swift's performance for iOS app developers, and I think iOS developers should naturally understand this kind of content.)

Follow-up course (scheduled to be released as an online class) 📈📆

• (1) Basic App Development Course - Creating 15-20 Apps Coming Soon
• (2) Understanding iOS Framework - Coming Soon
• (3) Creating UI with Code (Not Storyboard) Course Coming Soon
• (4) Instagram Clone (Follow-Along) Course Coming Soon

(Actually, I think you don't necessarily have to take my courses for the post-grammar processes. My courses basically include the process of building an app, and while building the app, you'll already understand the basic principles of how apps are created. After that, you can easily self-study with other courses, and I think other courses on building apps or frameworks available in the market are highly accessible.)


After taking my courses, self-study becomes quite manageable, and after completing my courses, I think you could also enter other bootcamp programs (for team project experience).

(Or you could think of my courses as a pre-course before taking other bootcamps. This is because they operate with a completely different philosophy from existing bootcamps. For non-majors, I believe you need to have a solid foundation in basic knowledge to keep up to some extent, so I teach everything in a spoon-feeding manner for basic knowledge. If you consistently review well, you can start with thoroughly solid fundamentals.

Of course, I'll also teach you about understanding basic principles and direction, so rather than weakening your problem-solving abilities (on your own), I think you'll be able to learn application methods without trial and error based on solid fundamentals.)
