100 Days of SwiftUI: The Complete 2026 Roadmap From Intermediate to Expert (Full Reading List)
SwiftUI shipped in 2019. By 2026 it isn't an alternative to UIKit anymore — it's the framework Apple expects you to know. Every WWDC release ships SwiftUI-first. Every iOS job listing assumes you can ship a production app with it. And every developer learning SwiftUI hits the same problem: tutorials end at the View protocol. Real apps start way past that.
That gap is why I wrote 100 articles in 100 days — one full curriculum from "What is a View?" to "Ship your first production app." No filler. No "5 hacks for @State" listicles. Just an honest, ordered path from zero to expert.
The Complete 100-Article SwiftUI Curriculum
Seven phases. One article per day. From the View protocol to App Store deployment. Free to read on Medium. Bookmarkable for life.

Who This Roadmap Is For
Three kinds of developers get the most out of this list.
Beginners who installed Xcode last week and want a structured path that doesn't leave you stuck after the first three tutorials. Start at Article 1 and go in order.
Intermediate developers who can build a small app but stall the moment something real shows up — state management, networking layers, App Store rejections. Jump to Phase 3 or 5 and fill the gaps.
Senior devs moving from UIKit who need a SwiftUI-native mental model fast. Skim Phases 1–2, then dig into Phase 4 (architecture) and Phase 6 (clean code) — the parts where UIKit habits actively hurt you.

10 Must-Read Articles From The List
If you only have ten article slots to spend, start here. These are the days where the biggest mental shifts happen.
-
Article 4
SwiftUI Layout System Deep Dive
The piece that makes the rest of SwiftUI click. Once you understand how parents and children negotiate size, every layout bug stops feeling magical.
-
Article 13
Animations in SwiftUI
The fastest way to make an app feel premium. Implicit vs explicit, transitions, matched geometry, animation curves — all in one place.
-
Article 18
Creating Reusable Components
The shift from "copy-paste this View" to "we have a design system." The single technique that scales your codebase past the toy-app stage.
-
Article 27
Empty States Design
The first state every screen needs — and the one tutorials always skip. Real apps spend more time in their empty states than their loaded ones.
-
Article 35
The @Observable Macro (iOS 17+)
The modern observation model that replaces
ObservableObjectin new code. Smaller, faster, less ceremony. If you're starting fresh in 2026, this is the default. -
Article 40
TCA (The Composable Architecture)
The community's favorite unidirectional architecture. Where it helps, where it overengineers, and what a real TCA reducer looks like in production.
-
Article 46
NavigationStack Deep Dive
The iOS 16+ navigation API that finally makes deep links, state restoration, and programmatic flows sane. Skipping this means stitching old NavigationView duct tape forever.
-
Article 62
Async/Await Networking
The modern networking layer in 30 lines. Cancellation, error handling, and the patterns that scale from a single endpoint to a full API client.
-
Article 70
SwiftData (iOS 17+)
Apple's modern persistence framework. The day the boilerplate of Core Data quietly disappears — and what trade-offs you accept when you switch.
-
Article 100
Building Your First Production App
The capstone. Everything from the previous 99 articles, applied end-to-end. Annotated decisions, real trade-offs, the full path from spec to App Store.
Why Bookmark This List?
- Curriculum, not random tips. 100 topics ordered the way a real iOS career touches them — not a random pile of features.
- 1000–3000 words per article. Long enough to be substantive. Short enough to read in one sitting. Each article has working code, not snippets.
- Production-focused. Every article ends in a shippable skill. Not theoretical demos that fall apart in App Review.
- Free to read. Every article lives on Medium. Free with a Medium account on most stories; a Medium subscription unlocks the rest plus offline reading.
- 2026-updated. SwiftData,
@Observable, NavigationStack, the modern concurrency model, current App Store Connect — not warmed-over 2021 examples. - Honest about trade-offs. Where SwiftUI breaks, where UIKit still wins, where TCA helps and where it overengineers. No fanboy energy.

Open the Reading List →How To Read The List (Without Burning Out)
100 articles is a lot. Here are the three schedules that actually work.
The Beginner Path. Article 1 to 100 in order, one a day for 100 days. Around 30–45 minutes per article including a small code experiment. By the end you've built dozens of small examples and the patterns are muscle memory.
The Weekend Curriculum. Five articles every Saturday, five every Sunday. Full list in 10 weekends. Pair with a single side project — one repo where every article's pattern lands. This is the schedule busy working developers actually finish.
The Targeted Hit. You know exactly what you're weak at. Jump to that phase, read 4–6 articles, ship the gap you came for. Use the rest as a reference manual for the next time it bites you.
What This List Is NOT
- Not a Swift language tutorial. Comfortable Swift syntax is assumed. If "optional chaining" or "trailing closures" feel unfamiliar, learn Swift first.
- Not a UIKit-to-SwiftUI migration guide. The series is SwiftUI-first; UIKit shows up only where it still wins.
- Not a WWDC recap. The framing is timeless: shipping production iOS apps. WWDC features get covered where they actually change practice, not as news.
- Not a paid course. Free on Medium. Tip the author if it helps you ship.

Do I need a paid Medium subscription to read everything?
Some stories are free, others sit behind Medium's Member paywall. A Medium subscription ($5/month or $50/year) unlocks the whole site, not just this list, and gives you offline reading on the app.
I've never written Swift before — can I still start at Article 1?
You'll struggle. The series assumes comfortable Swift syntax: optionals, closures, protocols, generics. Spend a few days on Apple's free Swift Programming Language book or Hacking with Swift's "100 Days of Swift" first, then come back.
Is the order strict?
For beginners, yes — articles 1 to 15 build on each other. After Phase 1, the phases stand alone. You can read Phase 5 (Networking) before Phase 4 (Architecture) without missing context.
How long until I'm at "expert" level?
Three to four months of consistent reading plus one real shipping project. Reading without shipping doesn't compound. The Phase 7 capstone exists for a reason — apply as you go.
Will there be articles after Day 100?
The 100-article list is the curriculum. Follow-up pieces on advanced topics (Vision Pro, Swift 6 strict concurrency, SwiftUI on macOS, App Intents) ship on the same Medium account — follow to catch them.
Can I share the list with my team?
Absolutely. Send the Medium list URL — it's built to be shared, bookmarked, and used as an onboarding curriculum for junior iOS devs. Each article stands alone, which makes it easy to assign specific phases as homework.
One article a day for 100 days. By the end you'll have shipped patterns, written tests, profiled performance, handled App Review, integrated payments, and built a complete production app — with a reading list you'll keep coming back to.
