The Future of iOS Development Belongs to You — And Everything We’ve Built Is Now Free
If you’re graduating soon — or you’ve just stepped out of university — this moment in your life is powerful. You’re standing at the beginning of something new, something uncertain, something exciting. The world feels wide open, but also a little overwhelming. And if your dream is to build iPhone apps, to become an iOS developer, or to create something people will use every single day… we want you to know one thing:
You’re in the right place. You’re capable. And this is your moment.
That’s why we’ve redesigned 3DaysOfSwift.com from the ground up — and why we’ve made every lesson, every Xcode playground, every code example, and every learning tool we’ve created completely free. Forever.
No subscriptions. No locked downloads. No “premium” section that hides the real value.Just clear, honest, accessible Swift education — built for beginners like you.
Why We’re Giving Everything Away
Over the last three years, we taught hundreds of young developers aged 20–25 who were exactly where you are now. Some came from coding degrees. Some didn’t. Some were confident. Some were terrified. But almost all of them felt the same quiet pressure:
“Am I ready to work in tech?”
“Do I know enough?”
“Where do I even start?”
“What happens if I fail?”
Here’s the truth:Nobody is “ready” at the start. Everyone begins confused. Everyone begins unsure.
What matters is the support you receive in those first few steps.
We created 3DaysOfSwift.com to give juniors the clarity they never had before. We built tools that let you run the code you’re learning, not just read it. We transformed confusing Swift concepts into simple examples you can execute in Xcode. We wrote real software that teaches real principles — so you can learn like a developer, not like a test-taker.
And we’re giving all of it away because we believe something deeply:
Your potential should never be limited by money, fear, or confusion.
Not at the start of your career.Not when you’re trying to find confidence.Not when the technology world is changing faster than ever.
This Is the Best Time in History to Become an iOS Developer
AI has shifted everything. Not in a scary way — in an exciting way. For the first time ever, juniors can learn faster, build faster, and understand deeper than any generation before them.
But there’s one rule: AI only makes you powerful if you understand Swift.
If you take the time now, today, to learn Swift properly — with clear explanations, real examples, and a supportive environment — you will enter the industry with an advantage that multiplies every single year of your career.
Swift isn’t just a language.Swift is the foundation of everything you will create. It is your gateway to opportunity.
And we want to help you build that foundation the right way.
We Believe in You — Even If You’re Still Learning to Believe in Yourself
You might not feel ready. You might be comparing yourself to others. You might think everyone else knows more than you. You might worry that you’re behind.
But here’s what we’ve learned from years of teaching young developers:
You’re far more capable than you think. You’re not behind — you’re beginning.And beginning is where every great career starts.
We’ve watched new developers go from unsure and anxious to confident and hired — simply because someone believed in them and gave them the right tools.
That’s what we want to be for you.
Everything Is Free Because Your Journey Matters
This isn’t a marketing line.This isn’t a discount.This isn’t a “limited-time offer.”
We redesigned our entire website because we want beginners — real beginners like you — to have a place to learn Swift without feeling overwhelmed, confused, or excluded.
The industry needs better-trained juniors.And you deserve a clear pathway into a career that can change your life.
So explore the lessons. Download the playgrounds. Run the examples. Build something small. Then build something bigger.Let this be the first step toward a career you’ll be proud of.
The Future of iOS Development Belongs to You
We’ll finish where we began:
This is your moment.This is your chance.And everything we’ve built is yours — completely free.
The world of iOS development is waiting for you.Your ideas matter.Your creativity matters.Your journey matters.
Welcome to the new 3DaysOfSwift.com.
Welcome to your future.Let’s build something incredible together.

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.
