The Compose Multiplatform Crash Course for 2025 - Build a Clean Code Book App

[@jaishkhan7442]

This guy is literally one of the nicest KZbinrs I have seen!

[@itscooldawgdonteventrip]

I have 5 years of experience in android and I learnt it by myself and it was pretty rough but the job market was super open so I got in quite good in the London market. All I can say is that it was hard to learn and I like to keep up to date with PL because there are not a lot of resource of quality ( Professional ) about mobile development I don't even know the PL of iOS. it's feel like mobile development is a self taught realm even more than the web. For the web you have a lot of bootcamp and stuff. | Anyway back to coding.

[@KevinCarlson]

Just 45 minutes in and I'm already learning a lot. Gonna take a few days to get through it all and make the most of it

[@rIyAsE]

Bro just published a Udemy course on KZbin ❤

New android learner and this channel is gold.

[@thomaswaldorf2829]

This is the best way to expose the platform to the community, and get it mainstream! Thank you sir!

[@jasv49]

Christmas has well and truly come early this year 😄 thank you so much Philipp!

[@eniskaner9528]

A few days ago, i decide to make my projects with CMP, then i saw your really instuctive video about it. It was really, really helpful to start with. Thank you so much Philipp 😄

[@brgame8]

What an Awesome video, it is 5 hours long, nice, great, literally one of the nicest KZbinrs

[@AlainMarleyB]

Bro is making 2024 memorable regardless what we went through ! PL, We LOVE you man

[@AlainMarleyB]

you liked my comment ? i bought a kotlin udemy course recommended by freecode amp in july 2024 to make something with my geology college studies. My instructor is not helping and some of his projects in the course have some errors. I am using your free courses to stay updated. Maybe i will make an app for registring geographic coordinates of our new rocks , saving interesting places ,navigate using a map, calculate distances ,chatting in realtime , have a geology museum inside phone , add some note Its big for me , i have monumental skill issue. Please sell me a relevant course 😢!

[@jarvis2913]

Excellent full course for compose Multiplatform for learning. Thanks for such a great course.

[@blackrider8883]

I got no clue what kind of stoopid developer I would be if you didn't provide us with all these videos Tysm man😭

[@vigneshwaranvicky2517]

Just completed the course, lots of things to learn. Thanks Philip 🎉

[@alexrudy]

What a gift 🎁 thank you, Philipp!

[@ubersticks]

This is great stuff. Philipp I have followed your courses for years and appreciate all you do. I like how you actually explain what is going on and not just demonstrate your typing skills :-) Something I am struggling with for CMP is how to get started on a new project. It is great that I can clone your starting project, but that is sort of cheating to me. I attempted to use the KMP Template starter on my own, but got bogged down on many dependency issues. I resolved most of them, but gave up after an hour and then just cloned your starting repo -- you have similar errors and warnings if you "rebuild project", so I am puzzled about what to ignore and what to worry about. If I ignore "rebuild project" errors and just press the build button in AS (green arrow) then everything works great and I am continuing the course and it is great!

[@senglund]

Tack!

[@SiamakAshrafi]

Wow ... this is very gracious of you ... thanks for your hard work and your contributions to the dev community !!!

Thank so much Philipp, we all here are grateful with you

[@JeudryPeñaPeña]

This is by far the best KMP video ever til the day.

What a big gift, thank you, Philipp!!!

[@HandleOnTheSpot]

ok look I gotta do some confessions here. you are my buddy and best friend that i would ever find who is doing youtube but also in android development and one thing i would say i'm no expert nor wealthy so only way to support is to share and like. and i'm saying it from literally from depth of my heart and I watching video and paused it to just get it out at 0:17 just know that there are still people and they have emotions which supports you and are not total dumb AIs :))

[@PhilippLackner]

@@HandleOnTheSpot thank you, happy learning 🙏❤️

[@Vihor95]

@@PhilippLacknerDo you think that KMP is ready on iOS or it is still possible sometimes to see junk ? I tried it few months ago but I saw that performance is not good and sometimes it is lagging on iOS. What is your experience?

[@DaleHawkins]

Thanks!

[@PhilippLackner]

Thank you too!

[@DaleHawkins]

@@PhilippLackner The timing on this is great! (Actually, I could have used it a couple of weeks ago, but this is still quite good). Thanks for the putting in the effort on this.

[@amirsaim4011]

"Absolutely fantastic tutorial! The level of detail and organization is impressive, from the clear breakdown of sections to the smooth explanations of complex topics like Ktor 3.0, Room database setup, and custom animations. The timestamps are super helpful for navigating through this comprehensive guide. Thank you for putting so much effort into making this tutorial both informative and engaging

[@brucehe9517]

Thank you for the awesome video! I’ve subscribed to your KMP course. However, I find myself leaning towards the Compose platform as it feels much easier to work with. While KMP does save a lot of duplicate code, there’s still quite a bit of platform-specific code that needs to be written. In contrast, the Compose platform is significantly simpler.

[@sepideh1085]

You've kept me motivated and inspired, and I really appreciate everything you do. Keep it up, you're making a difference!

[@silq300]

You are really a very special person and with the content you provide in jetpack compose there are many people who are learning and building their apps and you and every new programmer's opinions in kotlin MVM you deserve to respect my respect

[@ackeemmclennon9119]

1:48:08 I am still getting issue after changing height of vector xml. then I realized max line was 2 for author text. I didn't find the issue but I think it is related to column in the middle. after changing max line to 1 ui was looking fine.

[@anandA3b]

Wowww. Thanks a lot phillip🥺.

[@Narazgul]

Holy Terra! Dude, you rock!

[@lindaporsius]

The UiText is really good. I use it in all my projects now.

[@ubersticks]

at 03:17:18, that is clever how to share the *SelectedBookViewModel()* between List and Detail screens. However, it seems like it breaks the "separation of concerns" in that the navigation logic must now babysit the *selectedBook* and know about the *SelectedBookViewModel()* rather than focus on the single concern of navigation. It seems like the ViewModel(s) should be taking care of the data, not the Navigation section. Maybe let the List viewmodel take a parameter for the SelectedViewModel, and baby sit that when the book is selected or not?

[@azharalibhutto1209]

Great work ❤❤❤

[@neosuperstar]

Guy, really ... Thank You ♥

[@Chaseosa]

I'm having an issue here at 1:50:00. When debugging, onClick for the Tab hits a breakpoint, but the root and ViewModel never get hit. The code is the same.

i love you teachings, its usually packed with a lot of knowledge. My target is to buy all of your courses so far the ones i have purchased i can say am not the same I have a question what's your take on cursor AI, is it something that developers should be worried about or should we use it as a helper and not a threat

[@youarethecssformyhtml]

This AI madness needs to stop. Companies are fooling people by this stupid term so they can make money and attract investors. And no, AI is fake. There's nothing such as AI. It's just algorithms doing some math to give you answers

[@leandrobusquets5888]

Hi Philipp! Is there a way to get access to the "The Best Practice Guide to Android Architecture" course again?Thanks!

[@Sidner77]

Wow! This is amazing, thank you!,

[@Drackmord92]

Love the video, it came just when I wanted to start experimenting with this, thank you so much! I have a question regarding the module-by-feature approach: I really don't understand how it could work in the real world, where the data an app handles is so interconnected. For example, imagine you added a third screen which is fairly standalone but still requires access to your book data. How do you handle that? Either you include it into the "book" feature, or you make a separate feature, but then you have to basically move the whole "data" layer from "book" to "core" so it's shared between the two features. Now do that for every feature that is even only loosely connected, and you end up with most of your data layer in "core" anyway. What I've found success with so far is to keep the top level presentation/domain/data separation, and have presentation be split in features, while domain and data are split by resource/logical group. This way you can have multiple presentation features access the domain modules they need, and a feature is still extractable for re-use by taking the presentation feature and the domain/data modules it depends on into a new project. Thoughts?

Great tutorial! I've one additional question related to KMP - what is your recommendation for creating product flavors what will work for all platforms? For simplification let's assume that each flavor has a different version of the Composable function named the same. As far as I know, the traditional product flavors are not supported.
