SwiftUI Fundamentals | FULL COURSE | Beginner Friendly

Get your start in SwiftUI with SwiftUI Fundamentals. In this 12 hour course we build 4 apps that ramp up in difficulty. The first 3 apps are quite simple, but the 4th and final app grows substantialy in size and challenge. See the timestamps at the bottom of the description for the full curriculum.

The course has been updated for iOS 15 and iOS 16.

App 1 Weather:
We learn the absolute basics of SwiftUI to build the user interface of a weather app. If you have experience with SwiftUI, feel free to skip this one as it's very beginner friendly.

Weather Completed Source Code (Updated for iOS 16):

App 2 - Apple Frameworks:
We learn to build a Grid and pass data from our main view to a detail view.

Framework icon images:

Apple Frameworks Completed Source Code (Updated for iOS 16):

App 3 - Barcode Scanner:
We learn to use UIViewRepresentable to connect SwiftUI and UIKit in case SwiftUI doesn't support a type of user interface you want.

Barcode Scanner Completed Source Code:

App 4 - Appetizers:
This app is a big one where we put it all our learnings together to build a proper SwiftUI app that works with a network call (updated to Async/Await in iOS 15).

Appetizers Completed Source Code (updated for iOS 16):

[axemanaxeman]

Thank you @seanallen. I am already half way through your Swift language full course. Gonna come back here when I start SwiftUI learning.

[DeanWagstaff-kvgz]

I have viewed many tutorial for swift / swiftUI but above all I find your tutorials are great. Thank you for doing this.

[chiamakabrowneyes]

Sometimes, I just want to give these youtube tutors a big hug. Thank you!

[jwkranenburg]

Awesome video here and echo-ing what many have said that you are a great teacher and easy to listen to 🙌 I am have dabbled in SwiftUI a bit but the big value for me in this course was refactoring and structure. Thanks!

[bdhaliwal]

Great course. Sean you are an excellent instructor. I love your style of guided learning

[guilhermeteixeirademello]

Sean, you are an amazing person! Thanks for all you’re doing for the iOS dev community! You truly deserve the best!

[marcusstephannordal]

Thank you for the course Sean! I was trying to find a course that covers more than just the very basics, and this is perfect! Been following the course over the weekend, and I am finally getting a solid grasp of Swift!

[timurramazanov]

This course is exactly what I needed! Thank you so much for your work Allen!

[freddythompson]

I’ve been looking for two months and I’ve finally found a course that actually explains each step. I’ve learned so much already from just a couple videos. Thank you for doing these!

[sebastianpoliak]

Thank you for this amazing course Sean, exactly what I needed, keep up the great work!

[retroroar]

Wow, I found this to be really great! This is the kind of step-by-step learning that I actually like with getting sufficient information without being drowned in unnecessary details. This made me a big fan!

[deniskirisov]

What a coincidence that I’ve decided to build an iOS app and this sweet course was released on YT just a month ago! Perfect timing. Thanks a lot man, you managed to fit A LOT into these video, it’s a great intro. Now I have a better understanding of SwiftUI and how it works

[unk]

Thank you man for sharing so rich paid content, I am learning a lot! Wish you all the wealth you bring for who is watching.

[inan_dev]

You're the only teacher who can teach people swift and iOS in such easy way. Keep this up man. Take love <3

[silcalderale]

Already finished the Swift Programming Tutorial, and I'm R - E - A - L - L - Y enjoying this one!!! 💃💃💃 👏🏻👏🏻👏🏻 Sean!

[BreakingBarriersDIY]

Oh my! This is JUST the kind of thing you want to watch when looking at Swift UI for the first time. Such a great way of showing the basics and keeping you understanding "WHY" all along. Such superb talent at demonstrating and teaching. Instant subscription and now back to the course. <3

[palatfe]

Thanks Sean, You are master!! I start this video like 3 month ago but didn't have time to finish it, but today is the day. just want to say THANK YOU!!

[TheMrPifagor]

Just watched the course from the begin to the end.
Thank you Sean!

[vipinajayakumar]

Longest YouTube course I have watched! Thank you for making this freely available.

Like your teaching style, repetitions/reviews etc.

One thing I would have liked to see is testing, hand in hand with all the different features you showed us. I realise that's not everyone's cup of tea, but I wouldn't write an app for production use without any tests because I'd then be too scared to make any changes that might break it.

It's probably also a good practice to teach beginners.

[camilol-shide]

I can't thank you enough Sean. Will decimate it this weekend. Truly appreciate your work. 🙏🏻
