Recursion Fundamentals in Swift

A Practical Guide for Beginners Without a Computer Science Degree

What you'll learn
- Understand the concept of recursion and how it differs from iteration.
- Identify the base case and recursive case in a recursive Swift function.
- Build recursive solutions to common Swift problems involving strings and numbers.
- Trace the call stack of recursive functions step-by-step.
- Use recursion to navigate and process nested arrays and data structures.
- Write Swift functions that manipulate data without using loops.
- Apply recursion to solve file system traversal and tree-based logic.
- Debug common recursion errors like infinite calls and stack overflows.
- Solve interview-style coding challenges using recursion in Swift.
- Develop confidence in reading and writing recursive Swift code, even without a CS degree.

Requirements
- Basic understanding of Swift syntax (e.g., functions, variables, conditionals).
- Familiarity with writing simple Swift functions.
- Experience using Xcode or Swift Playgrounds to run Swift code.
- Comfort with reading and editing code in a code editor.
- Ability to follow logic step-by-step (no advanced math required).
- An interest in solving problems and learning how things work under the hood.
- Motivation to improve coding interview skills.
- Willingness to experiment, test, and debug your own code.
- Some exposure to arrays, strings, and integers in Swift.
- No computer science degree required — this course is designed for self-taught and bootcamp learners.

Description
Are you self-taught or bootcamp-trained — and feel like recursion is still a mystery?This course was built for you.

If you've tried to learn recursion from YouTube or textbooks but walked away confused, you're not alone. Most resources either rush through the topic or assume you already have a computer science degree. This course doesn't do that.

Instead,Recursion Fundamentals in Swifttakes aslow, clear, and example-drivenapproach to help you understand exactly what recursion is, how it works under the hood, and how to confidently apply it in real-world Swift development.

Who This Course Is For:

Aspiring iOS developers who learned Swift through bootcamps or self-study

Junior developers preparing for technical interviews

Mobile devs who want to strengthen their problem-solving skills

Anyone who's struggled to "get" recursion in a practical way

What You’ll Learn:

What recursion actually is — and why it's not as scary as it sounds

How to trace recursive calls step-by-step and understand the call stack

How to write recursive functions using clean base and recursive cases

Common recursion patterns: string building, array processing, tree-like structures

How to avoid common mistakes like infinite recursion or stack overflows

Practical use cases in Swift: working with strings, arrays, file systems, and more

How to spot when recursion is a better fit than iteration

How to use recursion to answer coding interview questions with confidence

Challenges You'll Solve:

Count digits in an integer

Reverse strings recursively

Search arrays for values recursively

Remove characters from strings

Traverse nested arrays

And more — with step-by-step explanations

Why This Course is Different:

You're not just copying code — you'rebuilding understanding. By the end of this course, recursion will stop being a buzzword and start being a tool you can actually use. You'll feel confident explaining your code and tackling recursive problems in interviews — without memorizing solutions.

Whether you're aiming to become an iOS developer or just want to fill a crucial gap in your Swift knowledge,this course gives you the solid foundation you need — without requiring a computer science degree.

Who this course is for:
- Self-taught Swift developers who want to strengthen their problem-solving skills.
- iOS development bootcamp graduates looking to fill gaps in foundational knowledge.
- Aspiring iOS engineers preparing for technical coding interviews.
- Junior developers who struggle to understand recursion in practice.
- Students new to programming who want to grasp core computer science concepts.
- Developers transitioning to Swift from another language (like JavaScript or Python).
- Swift learners who feel lost when recursion comes up in tutorials or books.
- Coders looking to practice Swift through hands-on, real-world coding challenges.
- Interview candidates seeking confidence with common recursion-based questions.
- Anyone who’s tired of skipping recursion problems and wants to finally understand them.
