Every Resource on 3DaysOfSwift.com Is Now Free
We want to begin with the announcement itself — because we’ve been waiting a long time to say this to you:
Every single resource we’ve created over the last three years is now completely free.The entire 3DaysOfSwift.com website has been redesigned.Every lesson, playground, code example, and learning tool is now yours — open, accessible, and free forever.
No subscriptions.No accounts.No paywalls.Just learning.
And we couldn’t be more excited to finally share this with you.
Why We’re Making Everything Free — And Why It Matters
For years, we’ve seen how difficult it can be for beginners to find a true starting point for learning Swift. If you’ve ever searched for “How to learn Swift,” you already know the problem:
Most courses don’t actually teach Swift — they teach iOS development and simply sprinkle Swift along the way.
They jump straight into:
SwiftUI
UIKit
views
navigation
UI layout
app-building patterns
Useful, yes — but not the foundation.
And without that foundation, everything becomes harder:
code feels confusing
debugging feels overwhelming
confidence drops
progress slows
learning stops feeling fun
We watched this happen over and over again with real juniors in real graduate programs. Brilliant young developers entered their first jobs already feeling “behind” because the internet had taught them iOS instead of Swift.
And that’s exactly why we decided to change direction.
We’re not here to teach you how to copy apps.We’re here to help you learn Swift — properly.
And now, every tool we built to solve this is yours, at no cost.
How We Set Out to Fix “How to Learn Swift”
Everything on this website — every playground, every utility, every example — was created while teaching young developers who were experiencing the same frustrations you might be feeling right now.
Instead of giving you 20 hours of UI tutorials, we built resources that take you deeper:
✔ Interactive Xcode playgrounds for real hands-on learning
You open them in Xcode, run the code, see what happens, and understand Swift through experience.
✔ A fully runnable version of Apple’s Swift book
We converted the entire text into an interactive Xcode playground so you can read, write, and run examples all in one place.
✔ Playgrounds that explain the hardest Swift concepts clearly
Optionals, protocols, enums, generics, ownership, structs vs classes, async/await — no fluff, no confusion, no mystery.
✔ Real-world examples refined through hundreds of live teaching sessions
Because these weren’t created in isolation — they were shaped by real juniors asking real questions in real classrooms.
We built all of this so beginners could learn Swift the right way:by experimenting, by understanding, by thinking in Swift.
Why We’re Not Charging for Any of It
We did test monetisation.We tried memberships.We tried paid downloads.We explored all the usual models.
But every time we added a price tag, something felt wrong.
Because our job — our calling — is to help you become a confident iOS developer. And we cannot do that if foundational knowledge is hidden behind a barrier.
We realised something simple:
If you want to improve the industry, make the foundations free.
When you remove the wall between beginners and high-quality education, everything changes:
students learn faster
confidence grows
more people enter the industry
juniors show up better prepared
the entire Swift community becomes stronger
That’s the impact we want to have.
And now that everything is completely free, we finally feel like 3DaysOfSwift.com reflects our true mission.
Why Learning Swift Inside Xcode Changes Everything
You can learn Swift by watching a video.You can learn Swift by reading an article.But you understand Swift by running Swift.
Learning inside Xcode means:
you see real behaviour
you make discoveries naturally
you build intuition
your confidence comes from action, not memorisation
you learn like a real developer, from day one
This is the most effective way to learn Swift — and now it’s free to everyone.
Not because it’s trendy.Not because it’s marketable.But because it works.
This Could Change How Beginners Start Their Careers
Imagine a world where every new iOS developer learns Swift clearly from the start.Where juniors understand the fundamentals before jumping into UI frameworks.Where self-taught developers feel confident instead of overwhelmed.Where the next generation enters the industry stronger than the last.
We believe this shift starts here.
3DaysOfSwift.com is now:
open
accessible
structured
interactive
based on real teaching
free forever
And that combination gives new developers — including you — the strongest possible foundation.
Every Resource on 3DaysOfSwift.com Is Now Free
We’ll end how we began, because this is the message we want you to take with you:
Every single resource on this website is free — permanently.The entire platform has been redesigned to give you the clearest, most beginner-friendly path to learning Swift.This is your starting point.This is your foundation.This is your future.
Whether you’re a student, a new graduate, a career changer, or a self-taught programmer…you belong here.
Dive into the playgrounds.Open Xcode.Experiment.Explore.Learn Swift the right way.
And know that we are here cheering for you every step of the journey.

Swift Career Tips 🚀
Also, as an additional bit of help 3DaysOfSwift has outlined a few career tips that might help as you start your journey as an iOS Developer applying for jobs writing software for Apple devices.
Tips 🚀
Below we have included a few career tips to help get you started as a Junior iOS Developer working in the tech industry.
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.
