iOS Developer Roadmap

A step-by-step iOS Developer roadmap: the full stack, the skills to learn in order and the best places to learn each step.

The stack, end to end

  • Fundamentals: Variables and data types, Loops and conditions, Functions, Problem solving, Git, GitHub, Branching and merging, Pull requests
  • Mobile: Swift, SwiftUI, Xcode, iOS app lifecycle, App testing, App store publishing, App permissions, Crash reporting
  • Backend: REST API design, JSON, HTTP methods and status codes, API documentation
  • Get hired: Portfolio projects, Technical resume, Interview preparation

  1. Programming and problem-solving basics

    Suggested pace: Start here

    Learn to think in steps: variables, conditions, loops, functions and how to break a big problem into small ones. A structured beginner course gives you the habit of solving problems on your own.

    Skills

    • Variables and data types
    • Loops and conditions
    • Functions
    • Problem solving

    Tips

    • Type the examples yourself instead of copying them, and change them to see what breaks.

    Where to learn

  2. Version control with Git and GitHub

    Suggested pace: Next

    Git records the history of your code and lets teams work on the same project. Learn to commit, branch, merge, resolve conflicts and open a pull request on GitHub. Almost every software job expects it.

    Skills

    • Git
    • GitHub
    • Branching and merging
    • Pull requests

    Tips

    • Put every practice project on GitHub. It doubles as your portfolio.

    Where to learn

  3. Swift and SwiftUI for iPhone

    Suggested pace: Then

    Swift is the language for Apple platforms and SwiftUI the modern way to build their interfaces. You need a Mac to build and publish iOS apps.

    Skills

    • Swift
    • SwiftUI
    • Xcode
    • iOS app lifecycle

    Tips

    • Follow Apple’s own tutorials first. They are well written.

    Where to learn

  4. REST APIs

    Suggested pace: After that

    An API lets a frontend, a phone app or another system talk to your backend. Learn resources and HTTP methods, status codes, pagination, versioning and how to document an API. Add GraphQL later if you need it.

    Skills

    • REST API design
    • JSON
    • HTTP methods and status codes
    • API documentation

    Tips

    • Test every endpoint with a tool such as Postman before building a frontend on it.

    Where to learn

  5. Testing and publishing an app

    Suggested pace: Later

    Learn to test on real devices, handle permissions and offline use, and publish to the Play Store or App Store, including the review rules and privacy information.

    Skills

    • App testing
    • App store publishing
    • App permissions
    • Crash reporting

    Tips

    • Read the store policies before you build, not after.

    Where to learn

  6. Build your portfolio, resume and interview skills

    Suggested pace: When you are ready

    Employers want proof. Finish two or three projects you can show and explain, put them on GitHub, write a clear resume that matches the jobs you apply for, and practise the interview questions for the role.

    Skills

    • Portfolio projects
    • Technical resume
    • Interview preparation

    Tips

    • Describe what you built, why, and what you would improve. That is what interviewers ask about.

Frequently asked questions

Where should I start with iOS Developer?

Start at step 1 and work down in order, because later steps build on earlier ones. If you are signed in, the roadmap compares your resume with each step and marks where you could start.

Do I need a degree to work as a iOS Developer?

It depends on the employer and the country. Many employers accept proven skills and projects, while others ask for a degree. Read the adverts for the roles you want and ask the employer if it is unclear.

How do I know I am ready to apply?

When you can build a small project from start to finish without copying a tutorial, and explain why you made your choices. Apply while you keep learning; you do not need to know everything.
