How to Learn Swift in 3 Days? 🚀

While it's highly unlikely to master Swift in just 3 days, you can gain a foundational understanding of the language's basics and potentially build a simple application. Dedicating focused effort, such as 3-4 hours per day, can accelerate your progress, but expect that mastering Swift for professional-level development will take significantly longer, potentially months or even years. 


Here's a possible 3-day approach:


Day 1: Core Concepts & Syntax

  • Set up your environment: Download Xcode and familiarize yourself with the interface. 

  • Learn the basics: Study variables, data types (integers, strings, booleans), and operators. 

  • Practice: Work through examples in a Swift tutorial or online course, focusing on hands-on coding. 


Day 2: Data Structures & Control Flow 

  • Learn data structures: Explore arrays, dictionaries, sets, and enums.

  • Understand control flow: Study if/else statements, loops (for and while), and switch statements.

  • Practice: Continue building small programs to apply these concepts.


Day 3: Functions, Classes, and Object-Oriented Programming

  • Learn functions: Understand how to define and use functions with parameters and return values. 

  • Explore classes and structs: Grasp the basics of object-oriented programming. 

  • Practice: Build a simple application that utilizes these concepts, perhaps interacting with data and using UI elements. 


Important Considerations:

  • Consistent practice is crucial: Make sure to dedicate time each day to coding and building projects. 

  • Don't be afraid to make mistakes: Embrace the messy process of learning and debugging. 

  • Utilise available resources: Explore online tutorials, courses, and the Swift community for help. 

  • Set realistic expectations: While 3 days can give you a solid foundation, becoming proficient requires consistent effort and practice over a longer period. 


For a more structured approach, consider these resources:

  • Hacking with Swift: Offers a free 100 Days of Swift course with a structured curriculum. 

  • Codecademy: Provides interactive lessons for learning Swift

  • YouTube: Many tutorials are available for free, like the one by freeCodeCamp.org

  • Stanford's CS193P course: A well-regarded resource for learning iOS app development with Swift. 

  • 3DaysOfSwift.com: Offers an online course and subscription to download coding resources, Xcode playground files, the official Apple Swift book to download, an Xcode playground version of the book with executable code examples, The Swift Cheatsheet code syntax reference guide, an example of professionally structured code projects and plenty of Swift tasks for you to write Swift code and solve coding challenges. 3DaysOfSwift.com also implements a "pair programming" style of teaching and each student will learn writing code directly in the software used by professionals in industry taught by experienced professionals with over 15 years experience in iOS.

By following a structured approach and dedicating focused time, you can make significant progress in learning Swift within a few days, even though mastery will require more time and effort.

Tips to Sky rocket Your Swift Career 🚀

  1. 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.

  2. 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.

    1. 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.

    2. 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."

  3. 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.

  4. 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.

  5. 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.
