iOS Development Masterclass 2027 – SwiftUI, SwiftData, AI (Udemy.com)
Build 19+ Apps – iOS App Development Course with Apple Intelligence, Agentic Coding, SwiftUI, SwiftData, ChatGPT, AI
Created by: Robert Petras
Last updated June 2026
Our take
Based on the ratings of 7,936 students, a sample of their written reviews and the syllabus, as the course stood in June 2026. No course pays to be reviewed.
Robert Petras built this as a project library rather than a lecture series. The syllabus shows 244 lectures and about 38 hours across 27 sections, and most sections are one finished app: a wishlist and grocery list in SwiftData, a Core Data to-do app, an Apple Watch notes app, a small game, and a Tinder-style card app. Nearly 50,000 students have enrolled, and it holds a 4.3 rating from 7,936 reviews. No programming background is required, so it mostly suits people who want to type along and see something running.
Students who like it call the teaching easy to follow, and they enjoy building step by step. The complaints are consistent, though. Many low-star reviewers say the videos show code being typed without saying why it works, property wrappers being one example. Several report voices that sound computer-generated, with commentary that lags behind the screen. Others say the pile of app previews at the start is tedious and the section order feels jumbled. One reviewer says parts date from 2020 or earlier and no longer match current Xcode. A few also miss networking and async lessons.
The last update was June 2026, and the description promises a larger refresh after WWDC26, so newer material is still arriving. That matters because the AI and agentic coding pitch is what the harshest reviewers say they did not find. Treat it as an app-building course first. For a beginner who wants a stack of small finished apps, it is generous in hours and easy to follow along with. Anyone who already programs and wants the why behind each choice should look elsewhere.
Pros
- Nearly every section is a finished app, so students end up with a portfolio of small projects
- Reviewers call it easy to follow, with step by step building that helps core concepts stick
- Covers SwiftData, Core Data, an Apple Watch app and a Mac game in one place
- Updated in June 2026, with a bigger WWDC26 refresh promised in the description
Cons
- Many reviewers say code is typed with little explanation of why, property wrappers included
- Computer-generated sounding voices, with commentary that can lag behind the screen
- Some sections are older and don't match current Xcode; reviewers also miss networking lessons
The course is very well explained and easy to follow. It really helped me understand the core concepts.
Stated as all levels. It really fits beginners with a Mac; one experienced programmer calls it a toy project.

Course Description
SWIFTUI COURSE UPDATES
A major course update is planned following WWDC26. The new content will focus on modern iOS development with SwiftUI, SwiftData, app architecture, Apple’s latest AI and Apple Intelligence technologies, testing, and production-ready development practices. The goal is to keep the course aligned with the current Apple ecosystem and the way real-world iOS apps are built today.
APPLE INTELLIGENCE and AGENTIC CODING
Agentic coding in Xcode refers to using AI agents that don’t just autocomplete code, but reason, plan, refactor, debug, and execute multi-step development tasks inside your project. With Apple’s growing investment in on-device intelligence and development tooling, this represents a shift from “code assistant” to “engineering collaborator.”
Faster Feature Development
Deep Swift & Apple Framework Awareness
Architectural Guidance (Not Just Syntax)
Automated Debugging & Fixing
Better Prompt-to-Prototype Workflow
Contextual Awareness Across Files
Continuous Refactoring Without Fear
Great for Solo Developers & Small Teams
Strategic Advantage in the AI Era
Additionally, we’ll explore the latest features and enhancements introduced in iOS27, macOS27, and watchOS27, ensuring that you are up-to-date with the most current tools and frameworks available for app development.
Stay tuned for more information on these updates, and get ready for an engaging learning experience!

LEARNING SECTIONS
SWIFTUI REFERENCE GUIDE
SWIFTUI RECIPES & HOW-TOS
SWIFTDATA – Store and load data on Apple Devices
APPLE INTELLIGENCE – On-Device AI and ChatGPT
APPLE DESIGN SYSTEM – Liquid Glass
WHY THIS COURSE?
Kickstart 2027 by mastering Apple app development with our best-selling SwiftUI & SwiftData Masterclass with ChatGPT AI course, which includes 37+ hours of high-quality video content. More than 48,400+ students cannot be wrong.
No1 – As you may know, Apple sent a clear message at the last WWDC developer conference: “The best way to build an app is with Swift and SwiftUI.”
That being said, I will focus on adding more fresh content covering many important topics, such as the following new features:
iOS 27, iPadOS 27, macOS 27, watchOS 27 platforms
Agentic coding with free OpenAI account in Xcode,
Xcode 27 with Apple Intelligence,
SF Symbols,
Liquid Glass Design,
Icon Composer,
Apple Intelligence,
Vibe coding with ChatGPT AI agent,
SwiftData,
On-device AI with Foundation Models,
TipKit,
Photos Picker,
Swift Charts,
Resizable Bottom Sheet,
New NavigationSplitView, NavigationStack,
Table for iPadOS,
MultiDatePicker,
Expandable Text Field,
ViewThatFits,
Improved Grid API,
Layout Protocol,
and so on.
No2 – I have already started uploading new content about what is new in the SwiftUI framework.
Not only that, but the entire course, including ALL projects, will be updated to the latest Apple platforms, including iOS 26, iPadOS 26, macOS 26, watchOS, and visionOS 26. Older projects will also get a refreshed and unified Liquid Glass design with enhanced features like on-device AI integration, modern UI design, and so on.
No3 – Every project is compatible with the latest iOS 2026, so if you run the finished project on the latest operating system, then Xcode will compile it.
I would also highlight that Apple did not deprecate previous SwiftUI versions. That said, the latest iteration of SwiftUI is nothing more than some new features and exciting additions to the base of all SwiftUI releases.
No4 – We are building applications from scratch with resources made by professionals.
Creating the Bestseller SwiftUI Course with high-quality production value takes a lot of time.
This SwiftUI course is already over 38 hours long and will continue to expand, including exciting topics such as voice coding with ChatGPT AI by the end of this year.
No5 – You will experience the "LEARNING BY DOING" teaching method during the course-taking.
Having said that, this is a project-based course, with 80% practical activities and only 20% theory.
I am aware of no other instructor in this category who offers more free previews than I do, so you can educate yourself about how things are done in this course.
I hope this information helps those who are new to app development.

I've been working as a software developer for six years. I write .net, PL/SQL, JavaScript, and React-native. In fact, an app I developed with React-native is now available on the App Store and Google Play. When I decided to learn Swift, I came across this course and took it. My familiarity with different languages makes me a fast learner. It goes into detail about modular architecture and explains it in detail with examples. I really liked using components, and I understood it clearly in the first video. Thank you for highlighting good points, showing the tricks without boring you, and contributing to my development. However, I think someone starting out with programming from scratch will struggle with this course. It might give someone who doesn't understand the logic the impression that we just wrote this code here and it's done. I wish you success.
By Justin Thomas on 9/16/2025
+ - Learn by Doing does work - Building solutions step-by-step is really effective - Good naming conventions and programming practices taught - - Many chapters repeat items already covered, some completely redundant - looks like they may be in the wrong order esp. section 24 (should be at the beginning?) - Deprecated code, examples don't match latest Xcode, some can't be followed at all [course is for 2025 but many sections are from 2020 or earlier] - Personally I find the constant cheesy/patronising phrases irritating: - 'Are you excited to.....' - 'How cool is that?' - 'How awesome.....' - 'Great job!' / 'Excellent work!' [all we did was copy your typing] - Mac Catalyst seems deprecated. The Mac checkbox on the Deployment section no longer exists. We need instructions on how to deploy to Mac using the current tools. - The Preview section has been replaced by #Preview - instructions on frame sizing etc do not work Suggestions: - Chapter on Data Persistence for multi-user apps like Firebase, Parse, Cloud Kit - Internationalisation: hard-coded texts -> i18n variants - How to create our own graphics - What about other types of apps like Document Apps? Even Frameworks and Libraries?

The course content appears geared primarily towards entry-level SWIFTUI learners. Much of the material was created using Xcode 11, which is now several versions behind the current Xcode 15. It would be beneficial to update the content to align with the latest Xcode release. Additionally, the course currently features a repetitive pattern of applications that may only be suitable for beginners. To provide more value, it would be great to incorporate more advanced and complex app examples that do not simply rehash the same fundamental concepts
By James G on 10/25/2023
Robert does a wonderful job of showing by doing the swift UI process. I found myself pausing the videos and trying to accomplish what i thought was the next step as he goes fairly quick, but i think this is a good thing there are no boring lectures, while a bit of background would be nice this is the first course I 100% completed. Thanks!! I just wish i could find other courses that could help advance my knowledge without using the bait and switch tactics that Udemy is allowing on most older courses
By Matteo Buompastore on 8/14/2023
The course is really good, but I must say that I had a good amount of working experience before taking it, so your experience may very different. The teacher does not dive into details in complex procedures and, although I was able to understand pretty much everything, I doubt that a beginner can do the same. On the plus side I've learnt a lot of new shortcut of XCode that will come in handy, and the apps are really good looking.
By Yourboye Thestudent on 6/9/2023
I have taken LOTS of courses and by far this one is among my favorites. I was completely new to SwiftUI but have taken Xcode through the years. SwiftUi can be a little overwhelming, but Robert's course was easy to follow (for the most part. The designs are gorgeous, which was a big reason why I wanted to try it out. He is an amazing designer and has put together lots of good info. He definitely has my respect and props. Here are some Cons to be aware of: * The course is based on making amazing UI, so he left some of the features without functions i.e. He put a search icon on the screen but added no search functionality. A shopping cart icon, with no additional functionality. * I am currently running Xcode 14 (06/09/2023) , and the course is mostly current. Although with any tech course, time = being outdated. So there were deprecated / soon to be deprecated code that needs to be updated. Not Robert's fault at all, it's just the nature of time. * The Q/A section is a great place to find some solutions, but I noticed that many of the responses were 2-3 years old. I've posted a handful of questions but only a couple got a response from other students. Not bad, but just know that if you can't get a reply, you have to be good at solving on your own through google, stack or reading documentation. Overall, great job Robert. Thank you for all your hard work and effort you put into this course.
By Alex Savvidis on 1/23/2023
I will start with the overall takeaway. Did I learn many things about SwiftUI that I didn't know before? Yes! Do I feel like I have a good foundation and a firm grip on the concepts I learned? No. In the entire course, a lot of concepts are used after a very minimal at best introduction or explanation while other very basic concepts are overexplained. For example, things like how the frame modifier works with the min, max, and ideal dimensions or why the order of modifiers matters in SwiftUI and how it works, are not mentioned at all. However, in literally every single section Robert will overexplain how to create a new project in Xcode and add a title and save it to your computer and import the assets...every time like we haven't done it 15 times already. This could be a much quicker process and the focus could be on making sure the students can build a good foundation in SwiftUI. If I didn't already have some knowledge in Xcode, Swift, and SwiftUI I think that after finishing this course, I would feel like I have done, but haven't learned. Is this course suitable for beginners as advertised? No. As mentioned above, a lot of things are not explained well or even mentioned at all and with the very high pace of Robert sometimes it feels like you do more than you learn how to do. I feel like the only reason I feel comfortable now is because I am not a complete beginner so it was a bit easier for me to keep up and also because I always made sure to review the entire code after finishing each app because that was when I was making sure that I actually understand what I am doing. Is the course structure good? No. The order of the modules is really random both based on the difficulty of the concepts you learn during the module and based on how old and outdated a module is. The course starts with Robert teaching us about gestures when we don't even know what SwiftUI is or how to use it and then the last few modules of the course are old, outdated, very basic modules with nothing new to learn and should have probably been in the beginning based on the difficulty. Also, Storyboards do not exist in SwiftUI anymore but they do in the last modules of the course, so I am guessing/hoping the course will be updated soon. Did the teaching experience appeal to me overall? No. Apart from the things I mentioned above, the whole course feels so scripted and unnatural. A lot of modules are "taught" by a robotic AI voice and the ones that are taught by Robert still feel like that, not because of Robert's tone or English, but because everything down to the dot is scripted and repeated over and over again. Sentences that apply to often occasions will always be said the same way with the exact same tone and words throughout the entire course. I do not like how scripted it is and it would feel more like a human being is teaching you if there was variation in how things are said. Like natural talking. It really feels like some sentences were recorded and played over and over again every time Robert wanted to say something similar.

This class has guided me through learning so many fascinating and useful parts of SwiftUI! In my opinion, this is a course for people who already have iOS coding experience and want to expand to SwiftUI. This course takes many turns down extremely technical trails that might leave the youngest student confused, but a slightly more advanced student will appreciate the level of detail and thoughtful code and ingenious application design. I am so glad I found this course! 10 out of 10!
By Valentino Borghi on 10/11/2020
I have completed the first project. It was thrilling. It is immediately evident from the details how accurate this teacher is in all respects. This teacher has super exaggerated knowledge on the subject. There are some methods in the graphics that will amaze you. I am extremely happy I bought this course at a ridiculous price considering the work behind it. Thank you very much for existing Robert. Greetings from Italy and sorry my way of writing but it is google translator that does it for me. Best regards Valentino Consiglio a priori questo corso. Il metodo che usa il docente è intuitivo e spiega passo passo come implementare le app. - Non è noioso. - Insegna con maestria a tenere il codice a moduli separati. - implementa le app con la programmazione ad oggetti - Da tutto il materiale didattico: dalla icona di presentazione ai colori personalizzati foto e video. - La grafica è spettacolare in quanto presenta anche effetti di movimento. - Non ci sono corsi a questo livello sul framework SwiftUI ( ne ho comprati diversi, ma tutti si limitano a presentare il pezzetto di codice e basta: qui invece fai l'app completa. Un investimento di cui non mi pentirò mai. Appena ne farà un'altro lo compererò al volo senza pensarci. - Il corso è destinato ad aggiornarsi con un app di vendita commerciale.(Non vedo l'ora che lo installa ora è solo in presentazione) Non preoccupatevi della della lingua inglese ; il docente parla una lingua molto pulita. Si può anche ( come ho fatto io ) tradurre in tempo reale le parole dei video lezione; basta installare l'estensione di google translate e selezionare in basso a destra la voce " trascrizione " cliccare sul simbolo in alto a destra dell'estensione google Translate e automaticamente appare a destra il testo tradotto nella lingua desiderata. Tutto ciò è fantastico. Lo consiglio a tutti per un vero approccio generale SwiftUI. Consiglio: aspettate l'offerta a 19,90 Valentino

Having done a number of online courses over they years I have experienced mixed results. This course has been a breath of fresh air, and I could not recommend Robert highly enough. Robert has a great delivery in his videos, which have been very professionally put together. The beatutiful assets he provides with each project make it a joy to develop a very polished application as you work your way through. Robert's attention to UI/UX design, as well as simple and effective coding practices, show how you can develop beautiful and functional applications with little effort. Overall, a fantastic course, and if you want to learn SwiftUI using practical examples this is the course for you.
