1. Free Preview
This first program serves as your gateway into the 3DaysOfSwift experience. It contains the first three lessons from Program 2, offering a free look at the teaching style, structure, and power of learning Swift through guided code. It’s designed to help you decide if this is the right learning method for you, without needing to commit financially upfront.
The content introduces you to Swift’s syntax and logic using a downloadable Xcode playground. You’ll run your first Swift code, explore variables, and see how playgrounds respond to live changes in real time. It’s not only about reading or watching—it’s about typing, experimenting, and seeing the results instantly.
For many learners, this free preview is the first time they’ve written real code in Xcode, and it gives immediate confidence. Within an hour, most students move from curiosity to momentum. It’s short, approachable, and gives you just enough insight to understand why this platform is different.
This mini-course can be completed in under a day, and it provides a complete, working foundation that flows directly into the main program—making the transition to full learning seamless.
2. Learn Swift in 3 Days
This is the flagship program and the core learning experience offered by 3DaysOfSwift.com. Spread across three intensive days, this course includes over 72 hours of on-demand video content and accompanying Xcode playgrounds. While it’s designed to be completed in three days, many students choose to spread it over five to seven days depending on their pace. The goal is not to rush, but to deeply understand.
Throughout the course, you’ll write real Swift code from scratch. Each lesson walks you through core topics such as variables, control flow, functions, collections, optionals, structs, and more. For each concept, there’s an Xcode playground file that you download, run, and edit as you learn. Every playground includes embedded challenges and guidance to make sure you’re not just watching, but doing.
The major benefit of this program is that it builds true confidence. Rather than memorizing syntax, you’ll learn how to structure logic, test ideas, and explore solutions within the Xcode environment. This experience is exactly how professional developers sharpen their skills—by writing code and seeing results instantly.
By the end of this program, students are equipped with real skills, real experience in Xcode, and a genuine understanding of how Swift works. It’s the best place to start your Swift journey if you’re committed to learning Swift properly and quickly.
3. The Official Apple Swift Programming Book (Converted for You)
Apple’s official Swift programming guide is packed with valuable information, but it can be dense and difficult for beginners to digest. This program takes that entire book and reimagines it as a live, interactive Xcode playground. Instead of reading walls of text, you’ll be stepping through the theory while executing real Swift code side by side.
Each concept from Apple’s original text is now paired with actual code examples that you can run and modify directly in Xcode. This format turns a theoretical manual into an exploratory, self-testing experience. You’ll understand more because you’re not just reading—you’re actively experimenting with Swift in real time.
This program typically takes 1–2 days to work through, depending on how deeply you explore each section. Because it’s organized as a reference-style guide, many students revisit it repeatedly throughout their learning journey.
What makes this program so valuable is that it bridges official documentation and real development. It helps you see how Swift is structured according to Apple’s standards, while giving you the tools to try those concepts instantly inside Xcode.
4. Downloadable Xcode Project (Ready to Submit to the App Store)
This program gives you access to a complete, working Xcode project that’s structured and ready to submit to the App Store. It’s not a mockup—it’s a real app with proper files, interface design, and logic. This is your opportunity to explore a full, production-ready Swift project from the inside out.
Inside the project, you’ll find all the Swift source files, storyboard or SwiftUI layouts, app icon setup, and build configurations. Everything is fully structured, just like a professional developer would organize an app for release. You can open the project in Xcode, explore how the logic flows, run the app in the simulator, and modify it to test your ideas.
This hands-on experience helps students understand how Swift is used in real-world apps. It moves you beyond the basics and gives you a feel for working in larger, more organized codebases. You’ll learn about file structure, targets, view controllers, and deployment settings.
Spending a day or two with this project will dramatically raise your confidence, especially if your goal is to publish your own app or apply for a junior iOS development role. It ’s a perfect next step after learning the language fundamentals.
5. The Swift Cheatsheet
This is your go-to reference guide—a smart, compact Xcode playground file filled with runnable Swift code examples. Instead of memorizing syntax or digging through online forums, you’ll have a structured file where each section demonstrates a core concept with code you can execute and edit.
Designed for everyday use, the cheatsheet covers dozens of Swift topics in a concise format. It’s perfect for review sessions, technical interviews, or moments when you’re stuck and need a quick example to jog your memory. Unlike traditional PDFs or printed cheat sheets, this playground lets you test code live and build on what’s shown.
It typically takes one day to explore the entire file in depth, but most students use it continuously throughout their studies and career. You’ll return to it often—not just during practice, but during real development and job interviews.
The greatest value of this program is its portability and practicality. It becomes your personal Swift reference hub inside Xcode, making you faster, more accurate, and more confident as a developer.
6. Swift Practice Pack: Self-Study Skills
After completing the core training, many students ask: “What should I do next to truly master this?” This practice pack is the answer. It contains seven separate Xcode playgrounds, each one focused on deepening your understanding of Swift through practical, scenario-based exercises. Instead of learning new theory, you’ll be applying what you already know in increasingly creative and challenging ways.
Each playground contains tasks that encourage problem-solving, code structuring, and debugging. The exercises are designed to mimic the kinds of questions you might be asked during a job interview or while building your own project from scratch. By working through these playgrounds inside Xcode, you’ll get used to thinking like a Swift developer—testing, refining, and experimenting until your solution works.
You can complete this pack in one to two days, depending on how much time you spend reviewing and expanding each task. It’s highly flexible and self-directed, which makes it an ideal tool for independent learners who want to strengthen their coding muscles before moving into more advanced topics.
This program is especially beneficial because it turns theory into practice. You’ll develop fluency, improve your coding speed, and build a portfolio of solved problems that demonstrate your understanding of Swift’s core principles.
7. Architecture: Snakes & Ladders
This program offers a unique learning opportunity: understanding software architecture through game development. You’ll build a playable game of Snakes & Ladders entirely within an Xcode playground, which might sound simple—but that’s exactly the point. The goal here is not to create the most complicated game, but to write clean, logical, and well-structured code for a game that has clear rules and player actions.
Over the course of a day or two, you’ll follow a natural coding progression—defining the board, managing two players, and enforcing game rules. As you go, you’ll learn how to break problems into smaller parts, how to keep your logic modular, and how to anticipate changes or additions to your code. These are essential architectural habits that every Swift developer needs.
Xcode’s playgrounds make it easy to test your game logic in real time. You’ll run simulations, debug game state, and see the direct effects of your choices in the code. This kind of structured experimentation helps you internalize what good architecture looks like, without needing to build a full app from scratch.
Snakes & Ladders provides the perfect foundation for thinking in terms of models, game logic, and maintainability—all of which are skills you’ll apply in professional software development.
8. Swift Practice Pack: ARC
Memory management is a crucial, often overlooked part of learning Swift, and this program tackles it head-on. ARC—Automatic Reference Counting—is how Swift handles memory allocation and cleanup for reference types like classes and closures. Understanding how it works is critical if you want to avoid bugs and memory leaks in real-world apps.
In this program, you’ll download a specialized Xcode playground that walks you through various ARC scenarios. You’ll experiment with strong and weak references, create and destroy objects, and observe how reference cycles form (and how to prevent them). The playground is designed to be hands-on, so you’ll learn by doing—not just reading theory.
The tasks in this program can be completed in about a day, but many students revisit the playground multiple times to reinforce their understanding. It’s the kind of deep, focused learning that’s hard to find elsewhere and often skipped by casual tutorials.
What makes this program so valuable is that it prepares you for the moment you leave toy examples behind and begin building larger, interconnected apps. ARC mastery is essential if you want to build reliable software—and this program gives you the experience and clarity to talk about it confidently in interviews or team discussions.
9. The Grandaddy of Xcode Playgrounds
This program is different from all the others. Instead of being a structured, multi-lesson course, it’s a single massive Xcode playground file filled to the brim with mini-lessons, review tasks, and inline challenges. It’s built as a comprehensive review tool—ideal for revisiting everything you’ve learned across the earlier programs.
Inside, you’ll find a wide variety of Swift tasks: from basic syntax reminders to more advanced topics like optional chaining, closures, and type inference. The challenges are varied and unpredictable—just like they would be in a real-world tech interview. Many students use this program as their final prep before applying for junior developer roles.
You can easily spend one to two days working through the entire playground, and you’ll come away with sharper instincts, faster recall, and a much stronger grasp of the Swift language overall. It’s perfect for those moments when you want to test yourself and discover any remaining weak spots.
The value of this program is that it brings everything together. You’ll review, revise, and reinforce your knowledge all in one place—inside a single playground file you can return to again and again.
10. The Complete Swift Handbook (Concurrency, Errors, Protocols)
This final program is your introduction to Swift’s more advanced topics—presented in a format that’s accessible, self-paced, and perfectly suited for independent study. The focus is on three major areas: protocols, error handling, and concurrency. These are foundational to building robust, scalable apps in Swift and are often expected in professional environments.
The program is styled like a digital handbook, but it’s delivered entirely through an interactive Xcode playground. For each feature, you’ll find a concise explanation, a live code example, and a short challenge to help you reinforce what you’ve learned. The experience feels more like a guided tour than a traditional course, and you can complete the full program in about one or two days depending on your depth of study.
By working through the handbook inside Xcode, you’ll be able to see how Swift’s most powerful language features behave in action. You’ll get used to async/await patterns, learn how to handle errors cleanly, and explore protocols as a way of designing flexible code.
This is the perfect capstone to your journey through the 10 programs. It doesn’t just finish the learning experience—it pushes you across the line into intermediate and advanced Swift territory. When you complete this program, you’ll have a working knowledge of Swift that’s not only deep, but well-practiced and battle-tested.

Tips to Sky rocket Your Swift Career 🚀
Focus on learning the Swift language itself. Most team members start their learning journey by studying Xcode and building apps. It's a lot of information and plenty to get confused about. Most of your colleagues will have many gaps in knowledge that affect their every-day anxiety with completing tasks and having it reviewed by others. Instead, why not become the one of the reviewers? Our advice is to stand out in the tech industry and if you want to stand out I would suggest becoming very knowledgable about the language itself; Every single developer will be using it and they will all be competing over Architecture and not the best use of language features. Armed with an incredible understanding of the language you will have the confidence in knowing you can maintain any existing product on the market.
Gather "Career Things" like they were collectibles in a game. This easy-to-remember and rather broad term is a great bit of advice. Too many engineers let the months go by without really taking on board many exciting projects or doing anything that wows any one. This is a terrible idea in every way. Stand out. Be the best at something (like understanding the language). When you change positions and apply to a different company you will have an interview and they'll grill you with many questions. The main bits to know are these; Your CV gets you the interview. You display your worth in the interview.
Your CV gets you the interview: Your short 2 page bullet-pointed CV is simply a list of amazing things you did to improve the team, the social element, the code quality, the income, how you increased user retention, how you added a successful feature and improved the app. You must collect career things.
You display worth in the interview: In the interview you want to fill the hour with saying similar phrases non-stop to "I was able to tweak the values and affect the income of the product simply by reducing the friction of the onboarding and providing a more seamless and pleasant user experience for the user. We now have only a 14% drop compared to most companies that have around 30% typically." Notice how you use "we" when referring to your current company in interviews. To simplify the phrase just-used, "I helped my company move forward. I improved the product, which led to an increased user experience and ultimately more profits for the company. I am a team player and I will improve your company at every opportunity possible."
Become confident in Interviews. You are now a talented Swift engineer who understands the Swift language and has a list of successful results you can pull out of the bag and discuss and any interview. You are constantly and infinitely talking about specifics of the Swift language and how cool and useful it is. You are stacking up one example after another of how you affected the results of the team and the company. You are great at telling these stories. The world is your oyster and you can be confident in your abilities as well as your choices in life.
Move company every 2 years. Ask for a £10,000 increase. When you become bored at your current job because you know too much think about moving, upgrading your job title and doubling your annual salary.
Be driven and be proud that you help keep the world moving by maintaining the digital services we all love and are constantly glued to.
