A well-structured Swift 5 course provides an excellent foundation for both beginners and experienced developers looking to master iOS and macOS app development. The best courses offer a comprehensive breakdown of Swift's core features, starting with the basics—such as variables, data types, and control flow—before diving into more advanced topics like closures, optionals, and protocols. What sets a great Swift 5 course apart is its focus on modern Swift features. Swift 5 introduces key improvements such as the Result type, Property wrappers, and function builders, which are essential for building efficient and maintainable applications. A good course will cover these new additions in depth, explaining their use cases and best practices, especially for developing with frameworks like SwiftUI or Combine. The teaching style should strike a balance between theory and practical application. A well-paced course will break down complex topics into digestible segments, with clear, step-by-step explanations and real-world examples. Hands-on exercises are crucial, as they help solidify concepts and give learners the opportunity to apply what they've learned in real projects. This is especially important for Swift, where understanding nuances like memory management and error handling can significantly impact code quality. In addition to Swift syntax and features, a high-quality course should emphasize best practices for writing clean, maintainable code and optimizing app performance. Integration with APIs, using Swift's concurrency model, and understanding how Swift fits into the broader iOS development ecosystem are all valuable learning outcomes. Lastly, an excellent Swift 5 course will offer ongoing support, such as access to community forums or mentorship, ensuring learners can continue to grow their skills after completing the course. In conclusion, a good Swift 5 course combines expert instruction, real-world examples, and hands-on coding to equip learners with the skills they need to succeed in iOS development.

아직 초반부분밖에 보지않았지만 코드스타일이 깔끔하고 보고 배울점이 많다고 느꼈다. 후반부분이 기대되는 강의다. ------ 중간까지 진행하고 작성하는 후기다. API통신 및 MVVM패턴, Delegate패턴, 코드컨벤션 등등 많은 정보들을 얻을 수 있고 지금까지 본 강의중에 거의 유일하게 질리지 않고 흥미있게 본 강의다. 영상을 보며 코드를 따라치지만 말고 미리 코드를 자신만의 방법으로 구현해놓고 그다음 영상을 보고 나랑 무엇이 다른지 확인하면서 학습하면 더욱 기억에 남는것같다. ----- 강의를 다 보고 작성하는 후기다. 일단 여기서 배우는 내용들은 배경지식이 없는상태라면 이 지식들을 온전히 습득하기가 어려울것이라고 생각한다. 완전초보가 보고 배우기에는 어렵지만 어느정도 배경지식이 있는 중급자정도라면 더할나위없는 최고의 강의이다.

PS: Read the whole text. I really liked the course and if i was you searching for a course i would buy this and stop wasting my time looking in other places. That being said i would like to warn that if you are new as a developer in general im afraid that you might wont be able to finish the course as the course has some bugs caused by the changes in IOS through this 3 years, that doesn't mean its outdated, it means that if you don't have the knowledge necessary to sense why theres some bugs happening you wont be able to find the solution because IOS development as well as Android development are a totally different flex, React or angular are easier compared to UIKIT and IOS in general. In the other hand there could be the case that you finish the course but the app would have some bugs but you could really don't care as the course is really well constructed for my taste so its worth doing it and for the price is the best option out there. So, in conclusion the course is worth it and it really teaches you how to do programmatically UIKIT and more important than that it gives you a insight on how to develop and app from scratch and I like Steven as instructor, he feels like a real g and a more organic teacher. -Peace

At starting I was struggling to follow up the Stephan because his coding speed feel little fast to me but I followed him and watched half of the course 2 times to understand about the content. I was little slow in the beginning xD. But later I got my speed and watched the remaining lectures at 1.75x and still I was able to get everything. Thanks to Stephan for this improvement in me. My coding ability has improved a lot. He really done a nice job. It was really nice following and coding with you. Great experience man. Peace!!

You can learn something. Right. But this project isn't finish! Details not done. Finally, you want to buy source code... It's not very well. And, this is not a full MVVM architecture. Maybe confuse some people...

I previously only knew SwiftUI and knew for my next app I couldn't launch it with SwiftUI's current state. I was definitely overwhelmed with UIKit programmatically and UIKit in general compared to SwiftUI's reactive programming. BUT WOW this tutorial caught me up to speed. I can mentally differentiate between the two and feel so much more comfortable diving deeper in UIKit. Amazing course man

Excellent course that really takes my coding skill to a new level. Learn tons of cool features and also organize my code neatly. TAKE NOTICE that this is not a beginner course, a beginner may be able to finish the course, but he will not understand anything. Gotta be familiar with Swift and Xcode and Firebase in order to digest all information Stephan gives out.

Stephen did a great job explaining all significant aspects of the architecture and design patterns. I really enjoyed the course and would recommend it to anyone, from complete beginners in Swift to experienced developers, who want to expand their horizons and learn iOS development by example. Bear in mind, though, it's not a zero-to-hero course, and you need to have some prior programming experience. The resulting app looks and works great, I've fixed a couple of minor UI bugs and did some refactoring, but apart from that, you're getting what's advertised in the course demo. Stephen asked for constructive feedback so here's something I think can be improved: - Unit tests and IU tests. I know it's tedious and time-consuming, but it's a good practice, so I thought it would be great if you could include a couple of examples and shared best practices. - Programmatic UI, constraints and alignment. It would have been helpful if you'd briefly explained anchors, constraints, alignment and programmatic layouts. - ViewModel and access control. It just seemed wrong making variables public and allowing to modify them via ViewModel. A ViewModel could have had a mutating function to update its private variable instead (i.e. increment/decrement likes, toggle isFollowed etc.). Overall, I believe this was a good investment in myself. I recommend this course to everyone and looking forward to purchasing more from Stephen.

I completed the course and my review: As one who works a full job as an iOS Developer, I saw this's the best course ever made in Udemy and includes a lot of features. Stephan is really professional, he expands my thought in code and improved my code structures, I faced the problem and wasn't sure the right solution but Stephan answered with a nice organization way. I highly recommend this course, defiantly I'll buy more courses for you especially in SwiftUI. I'm excited to see what upcoming from you next, Thank you, Stephan

Great course must better than his Twitter and original Instagram one. His og insta one does have more stuff, but none useful. This version has almost everything you need and he does a much better job of explaining the code in this. It is missing a few features but it's forgivable, if you check his youtube channel or do his twitter course for some extras.
