iOS still punches above its market share. Despite representing around 20% of global smartphones, iOS captured 70% of consumer app spending in 2025. For developers, that gap is the opportunity.
The hardest part of getting started isn’t the code. It’s the decision paralysis. SwiftUI or UIKit? The answer: learn SwiftUI first. It’s Apple’s current default, and the best free beginner resources are built around it. UIKit comes later, when you’re job hunting or stepping into an existing codebase.
From over 1,100 iOS development courses on Class Central, I picked 9 entirely free courses for this Best Courses Guide (BCG). A separate section covers paid and advanced options for those who want to go further. All picks cover recent iOS and Xcode versions, and carry strong recommendations from the iOS developer community.
One practical note: you’ll need a Mac to follow along with any of these courses.

Start with SwiftUI, not the SwiftUI-vs-UIKit debate
Beginners lose days arguing framework choice in forums before writing a single line of code. The debate isn’t pointless, but it has a clear answer right now: SwiftUI is Apple’s current default, and the strongest free beginner resources teach SwiftUI first. UIKit is worth learning later, once you’re job hunting or dropped into an existing codebase. 100 Days of SwiftUI is the clearest example of this: it’s free, assumes no prior programming knowledge, and walks you through 19+ real apps at a pace most people can actually finish.
You may notice that the first course in this BCG is the same as in our Swift BCG. That’s because it’s the best starting point for iOS developers who need Swift.

How We Chose These Courses
Given how much noise exists around iOS learning, I looked for courses that get you building real things quickly, then keep you moving through distinct stages of the learning path: architecture, backend, packages, and eventually UIKit.
- Builds at least one complete, runnable app rather than isolated code snippets
- Covers SwiftUI as the primary framework, not a footnote
- Introduces UIKit only where it’s practically relevant, like interview prep or existing codebases
- Addresses a distinct skill gap in the learning path, from backend integration to third-party packages
- Paced or structured so a self-taught learner can follow without a formal syllabus
Rankings lean on learner reviews on Class Central, ratings on the platforms hosting each course, and what working developers recommend on Reddit. Class Central has tracked online courses since 2011, and our team has completed 400+ courses across topics. Stanford’s CS193p earned its spot because it picks up where beginner courses leave off: it teaches MVVM, state management at scale, and even ports a finished app to macOS, skills that apply directly to structuring larger, multi-platform codebases. If you’re ready to begin, open 100 Days of SwiftUI and complete Day 1 today.
Best Project-based Course for Beginners Learning SwiftUI (Hacking with Swift)
100 Days of SwiftUI is the clearest starting point for anyone who wants to build iOS apps from scratch. Paul Hudson structures the course as a daily commitment: one hour a day, 100 days, with progress posted publicly. The daily structure and public posting are intentional design choices. The course explicitly warns against jumping between resources and against learning in isolation, and it backs that up with a companion app (Unwrap) and a community to lean on.
The first two weeks cover Swift fundamentals, with short tests after each day to help it stick. From day 16 onward, you build 19+ real SwiftUI projects of increasing complexity, touching state management, SwiftData, Core Image, MapKit, animations, and iPad optimization. Consolidation days are spaced throughout so nothing gets left behind. Day 100 ends with a final exam; an epilogue points you toward what comes next.
It requires no prior programming experience and costs nothing. The content is fully updated for iOS 17 and Xcode 15.3+, which matters in a field where tutorials go stale fast.
Once you finish, CS193p from Stanford is a natural next step for learning professional app architecture with MVVM.

Best Broad Introduction Covering Swift, Xcode, UI Frameworks, and Career Tips (Sean Allen)
Swift Programming Tutorial | FULL COURSE | Absolute Beginner is the widest on-ramp in this guide. In just over ten hours, Sean Allen covers the Swift language from scratch, builds two apps, explains the iOS ecosystem, and closes with career advice for junior developers. No other course in this guide covers all of that for free.
The syllabus is deliberately broad. You get Swift fundamentals (variables, optionals, structs, classes, enums), a tour of Xcode, and two real app builds: a Colors app using UITableView and a Card Workout app built first with storyboards, then rebuilt programmatically. A SwiftUI overview rounds out the technical content. The course was recorded around Xcode 12–14, so some UI details are dated, but the language fundamentals hold up.
What sets this apart is the career advice. Allen covers iOS dev paths, why WWDC matters, how to use Twitter for networking, and recommended blogs, books, and podcasts. Bonus videos include “Homeless to $130k iOS Dev” and “37 Tips for Jr. Developers.” For someone deciding whether iOS development is worth pursuing, that context is as useful as the code.
The tradeoff is depth. Two apps in ten hours means neither gets deep treatment. When you’re ready to build something more substantial, move on to SwiftUI Fundamentals for the project-based depth this course intentionally skips.

Best for Building Real SwiftUI Apps Through Four Projects of Increasing Complexity (Sean Allen)
SwiftUI Fundamentals is structured around four apps of increasing complexity, which gives it a clear arc that pure tutorial courses often lack. You start with a Weather app to get comfortable with layout and basic state, then move through a grid-based Apple Frameworks app that introduces MVVM and UIKit integration, a Barcode Scanner that adds camera access and error handling, and finally a full Appetizers app covering networking, async/await, image downloading, @AppStorage, and @EnvironmentObject. Nearly 12 hours of content, all free.
The Appetizers project is where the course earns its place. It covers the kind of real plumbing, including network managers, loading states, empty states, and alerts, that beginners rarely see until they try to build something on their own and get stuck. Sean Allen also tags iOS 17’s @Observable at the end, so the course doesn’t leave you stranded on older patterns.
The progression here complements CS193p from Stanford, which goes deeper on MVVM architecture once you have this hands-on foundation.

Best Official Apple Course Covering SwiftUI, UIKit, and MacOS (Apple)
Develop Apps for Apple Platforms is Apple’s own tutorial series, which means it tracks the current SDK. Because it is built and maintained directly by Apple, it tends to reflect current APIs as they evolve.
The series spans four sections and roughly 17 hours. You build four real apps: a scrum-meeting tracker in SwiftUI, a reminders app in UIKit, an earthquake data viewer that pulls live JSON from a remote server, and a macOS document app. The SwiftUI chapters cover state management and SwiftData persistence. The UIKit section assumes you’ve finished SwiftUI or have equivalent basics. The “Next Steps” section introduces structured concurrency, generics, and network testing. The macOS section covers platform-specific patterns like multiple windows, drag and drop, and AppKit integration.
By the end you’ve touched audio recording, custom drawing, JSON decoding, caching, and EventKit sync. That’s a wider surface than most beginner courses attempt. The tradeoff is that this tutorial has no built-in pacing, daily structure, or community support the way some other picks in this guide do. If you want that kind of structure before tackling this material, 100 Days of SwiftUI is a strong place to start first, given its daily format and guided progression.

Best for Learning Professional App Architecture with MVVM and State Management (Stanford University)
CS193p – Developing Apps for iOS is Stanford’s free iOS course, and the Spring 2025 edition is the one worth taking. Published in full in December 2025, builds CodeBreaker, a code-breaking game that grows across all 16 lectures.
What sets this course apart is how seriously it treats architecture. By lecture three, it’s already separating Model from UI and introducing the Swift type system. That thread runs through the whole course: data flows from the Model through one View and into another View, generics and protocols get real treatment, and SwiftData (not the older Core Data) handles persistence across lectures 13 through 15. The course focuses on why an app is structured the way it is, not just how to make it compile.
The course carries one honest caveat from Stanford itself: it predates iOS 26 and Xcode 26, so Liquid Glass UI and Xcode’s built-in LLM assistance aren’t covered. Stanford notes the code is mostly compatible anyway. There’s no official support for outside learners, but PDFs, assignments, and starter code are all publicly available.
This isn’t a starting point. If you’re still getting comfortable with SwiftUI views and modifiers, 100 Days of SwiftUI builds that foundation first.

Best for Job Seekers Learning UIKit Through a Real Interview Project (Sean Allen)
iOS Dev Interview Prep – Take Home Project – UIKit – Programmatic UI is built around a format the course presents as a take-home project brief. Sean Allen hands you a spec for a GitHub-followers-style app and walks you through building it from scratch, entirely in code, no storyboards. That constraint is deliberate, and the course is explicitly framed as a take-home interview project.
Sixteen hours covers a lot of ground: custom UI components, networking with Swift’s Result type, UICollectionView with diffable data sources, image caching, pagination, persistence, memory management, and ARC. The course then runs a full optimization pass, touching dynamic type, older device support, and bug fixes. It closes with interview-specific advice, including sections on interview next steps and what to do after project turn-in, which are listed in the syllabus. Bonus sections bring the codebase up to iOS 17, adding async/await, SwiftUI cells inside UIKit, and UIKit previews.
This is a job-hunting course, not a first course. If you’re still building your UIKit foundations, Apple’s official app development tutorial covers UIKit alongside SwiftUI at a gentler pace before you tackle interview prep.

Best Course for Integrating Firebase Auth, Firestore, and Analytics into SwiftUI Apps (SwiftfulThinking)
SwiftUI + Firebase is a 23-video bootcamp that covers Firebase auth, Firestore, Storage, Crashlytics, Performance, and Analytics inside a SwiftUI app. Over 13 hours, it moves from connecting Firebase to Xcode through the auth methods it includes: email/password, Google, Apple, and anonymous sign-in. That breadth alone makes it useful.
The backend coverage is substantial. The course covers Firestore in real depth: setting up user profiles, fetching with Codable, working with maps and arrays, sorting and filtering queries, pagination, sub-collections, and real-time listeners. It then adds Firebase Storage for user content, Security Rules, Crashlytics, Performance monitoring, and Analytics. Those topics together represent a practical feature set for real app development.
Each video targets a specific Firebase capability, so you can follow the series end-to-end or jump to the piece you need. The same channel’s Swift Packages course pairs naturally if you want to round out your dependency management skills alongside Firebase.

Best Short Course for Adding Third-party Swift Packages to Projects (SwiftfulThinking)
Swift Packages (Intermediate Level) covers something most beginner courses skip entirely: how to pull third-party libraries into a SwiftUI project and actually use them. In two and a half hours, it walks through six real packages, including SDWebImage and Kingfisher for image loading, Keychain-Swift for secure credential storage, and Lottie for After Effects animations.
The selection is practical. Image caching and secure storage are common requirements, and the course covers two different image-loading libraries (SDWebImage and Kingfisher) rather than just one. Lottie is a bonus: it renders animations made in After Effects.
Two of the six packages are the instructor’s own (SwiftfulUI and SwiftfulRouting), which is worth knowing going in. Unlike the other four, which are independent third-party libraries, these two are not maintained by outside contributors. Treat those sections as optional depending on whether you plan to stay in the SwiftfulThinking stack.
This pairs naturally with the channel’s SwiftUI + Firebase course if you want to add a backend to what you build here.

Best for Building One Complete Multi-tab iOS App from Start to Finish (iOS Academy)
Build Full iOS App (Rick & Morty) 2023 is a single, uninterrupted 34-hour build of a real, multi-tab iOS app. You start with project setup and source control, then work through every layer: API integration with the public Rick and Morty API, pagination, image loading with caching, compositional CollectionView layouts, and view models throughout.
This course covers four full tabs: characters, episodes, locations, and settings. The settings tab is built in SwiftUI and embedded inside an otherwise UIKit app. The search feature spans all three content types, includes a bottom sheet for options, and handles paginated results. The course ends with iPad and Mac layouts, then bug fixes.
The course spans 58 parts and follows one continuous app from start to finish, covering more surface area than a typical single-feature tutorial.
