Kotlin Multiplatform Masterclass - KMP, KMM - Android, iOS (Udemy.com)

This course is really getting to the point. No noise and definitely not about the author. He just wants to tell how to create a KMP app with a common architecture. Great course.

I am an experienced KMP developer, so using this course as a refresher. Soo far it is good content for this purpose as its succinct and straight to the point. Content has aged quite well (from 2023 to now), with only the comment about KMP not supporting Sealed classes - which it does now in 2026 - but I do see why author may still not want to use the Sealed as you would still have to use a interop wrapper class util. Only real negative is that he isnt creating any real tests yet, but instead manually running up the app. I will see whether he then goes back later and adds KUnit tests to the common code and maybe UI tests for Android ComposeUI and IOS SwiftUI

Because the mobile development world moves fast a lot of the example material is already out of date. I think starting this course with a more detailed overview of where to find which versions of kotlin and relevant libraries work together would have been helpfull. An explanation of what need to happen if you click the 'gradle upgrade' button in android studio?

It covers the basics in a way that is not too detailed but complete enough. Good course if you're starting with some experience on either platform or both. Some architectural concepts are not very well explained (or straight up contradictory) but they are explained in a way that is good enough for the purpose of the course.

It's a really amazing and basic course. Yes, it's little bit older in terms of library use, so facing some issue with new library. But as mentor has already told to follow configuration as he is teaching on. Good explanation about clean architecture and showing to build up case.

The best course to learn KMP, because the instructor show us how to work both with Android an iOS, giving examples with SwiftUI and Compose, so even if you are an iOS Developer it's gonna be easy to understand the concept and the project structure.

The course provides a solid introduction to Kotlin Multiplatform (KMP) with practical techniques applicable to real-world scenarios. However, it lacks coverage of essential topics like concurrency (e.g., how suspend functions work across platforms), testing, and integrating third-party or platform-specific libraries (such as maps and location services). I rated the course 3.5 stars because several modules are broken, and some lessons lack depth in iOS development, indicating the instructor’s stronger background in Android. Troubleshooting these issues can be time-consuming.  I wouldn’t recommend this course to beginners or junior developers due to these challenges. However, intermediate developers with experience in at least one platform may find it a worthwhile and challenging learning experience.

KMP is developing quickly and the course material is getting a little dated, but it's still solid and everything can be made to run with relatively few modifications as of 01FEB2025.

I highly recommend this Kotlin Multiplatform course! The material is presented in a clear and concise manner, getting straight to the point without any unnecessary fluff. The instructor does an excellent job of breaking down complex topics into understandable segments, making it easy to follow along and grasp the concepts. Whether you're new to Kotlin Multiplatform or looking to deepen your understanding, this course is an invaluable resource. Worth every minute!

This class has exactly basic functionalities needed to tackle real-life production cases. Being able to go over Ktor / SQLDelight as well as seeing SwiftUI for the first time was a pleasant experience, especially with a teacher who properly articulate and does not speed through a topic even though the videos are around 5-9mins. Excellent Class professor Petros!!
