Getting started with functional programming in Swift
This course is designed for developers who are new to functional programming, and is comprised of theory and practice to help them gradually change their existing way of thinking.
There were many parts that were difficult to understand on my own, but thank you for explaining them in an easy-to-understand way with simple and intuitive examples.

It's really good. It's helpful because there's a process for solving problems yourself.
What you will gain after the course
Basic concepts of functional programming
Implementing a practical project using Swift
Refactoring an existing program to a functional programming style
Functional programming techniques for solving concurrency problems

Things to learn
With the growing interest in functional programming, this course begins with a basic understanding of functional programming, then moves on to practical projects and practical applications. You'll learn how to convert existing source code to functional programming, developing a natural and practical understanding of functional programming. Ultimately, you'll develop an iOS app with a UI, mastering design techniques and practical application methods.
Part 1: Concepts of functional programming Part 2: Structured to allow hands-on learning of frequently used techniques Part 3: Converting an existing program to functional programming Part 4: Developing an iOS app that applies UI
Functional Programming, Getting Started with Swift - Swift FP
This course is designed for those who, no matter how hard they try to understand Functional Programming (FP), find its fundamental structure overwhelmingly unfamiliar, its differences from OOP, and its inconvenient and challenging nature. This special lecture is designed for those new to FP, and it combines theory and practice to help them gradually shift their existing mindset.
Case-based, not theory-based
Explain with direct code rather than explaining difficult concepts or terms.
It is structured as a hands-on course so that you can learn by typing directly.
Pair programming method allows learning functional thinking and programming process.
Includes projects that proceed from functional design to UI app implementation.
Operating environment: Mac OS, XCode 9 or later
Prerequisites: Swift 4.x
Functional programming is something that many developers want to learn now.
In recent years, interest in functional programming (FP) has grown significantly. Discussions about FP have become a common sight at meetups and seminars across various fields. In particular, we often see examples of refactoring existing code using FP techniques, and we often hear encouragement to widely adopt this beneficial approach. However, given that many developers are accustomed to the object-oriented programming paradigm, transitioning to a new paradigm requires significant effort. This is different from learning a new language and mastering its syntax.
Why is it difficult to move to a functional programming paradigm?
A programmer's cognitive system (paradigm) is deeply involved in every process, from designing the program structure to writing the source code. Assuming this programmer has spent their entire life programming within the object-oriented programming paradigm, learning functional programming anew can present the following challenges:
The very idea of not changing the value of a variable feels strange. To put it more developer-friendly, the very idea of programming without state feels incredibly awkward.
The concept of "currying" in FP is also strange. I don't understand what it means to create a function that creates a function that creates a function (that's not a typo).
It's strange to control the behavior of a program without changing its data. It just feels weird.
