@Sevak Tadevosyan I just looked at the book on Amazon (I'm fairly new to KMP). This book looks like the right kind of source for me to use for learning. Would you recommend it, based on the previous edition?

Yes sure, it is the best book that can help you to learn KMP

Does the KMP book spend much time on Compose, or is it mostly for code behind the UI?

Both, you will learn everything for KMM, take a look on this page: https://www.kodeco.com/books/kotlin-multiplatform-by-tutorials

I just ordered the 2nd edition of the book you mentioned, should have it on Sunday. I'm hoping this is precisely what I've been wanting to really ramp up my Kotlin skills for Android and iOS. Thank you for bringing it to my attention! 😄
