Creating Your First Hello World KMM App (Kotlin Multiplatform Mobile) - KMM for Beginners

[@TheTuxtrons]

I deliver my first project as a freelancer past week, couldn't take the second one cause client require also an iOs app. This came in perfect time.

[@aakashr79]

Hey Phillip. An OG supporter of your content here. A video on building a KMM library would be sooo massive. This is the best time to be getting into sdk dev for KMM where devs could be adding huge value for the future. A production level tutorial for a library would definitely be a first on KZbin and soooo helpful. Hope this reaches you and we see a video on that soon. Cheers!

[@danilodequeiroz9520]

👍

[@EmanNollase]

thanks Philipp! this is just in time. i am also exploring KMM. btw, i am a android and ios native developer. But i was grateful for your videos about jetpack compose. thanks again!

[@osisuper98]

How easy is it to go native on both platforms? Would you recommend it or it’s just better to use KMM for anything iOS related? I am a native Android developer who loves Kotlin and Java so much. The issue is I am quite unsure about choosing between learning iOS native or just sticking with KMM.

[@EmanNollase]

@@osisuper98 when developing app using KMM, you should have at least a basic knowledge of iOS native or learn iOS development. Because it defeats the purpose of KMM if you want to develop the app on android only. Might as well do a regular android project.

[@anudeepananth]

Cant tell you how incredibly excited I am for this....

[@shelarsameer]

Great for me, I just started learning KMM so that I can work on a project at my org. Please release more videos in this playlist.

[@arturolatorre371]

This series is gonna be the bomb! I'm all in! Thank you Philipp ❤

[@ezefrancatube]

Thank you for your video. It's more updated than official Kotlin docs.

[@osisuper98]

Thank you Philipp! We can’t wait to follow through your KMM series and learn cross platform with you.

[@DevRodMastria]

Great video! I'm also a KZbinr so I would recommend you to edit the closed captions via KZbin Studio > Content > video Details > Subtitles > Duplicate and Edit the Automatic Subtitles > Edit incorrect words like Japan vs Jetpack > Publish > Thanks for the excellent video!

[@trocchiettoski]

Really Happy you did this video. When the best Android coach in the world does this video the community think over (with the time) on making KMM better, and we will see compose IOS as flutter with a dedicated library

[@davidrauca]

Hey Philipp, Great work with all of these videos. Keep doing that! It would be nice to see a tutorial in which the KMM part is a library imported in existing Android & iOS projects. I think that would be very interesting and helpful!

[@mr.getrighhttt3433]

I wonder how many times you have said “actually” in this video. Lol great tutorial btw. I Have to create a KMM project for my job, and this helped. Thanks.

[@vedx]

Finally the wait is over ♥️

[@smreha]

I am so glad that JetBrains have improved the tooling. Look forward for more videos.

[@amirrezaashouri]

What a magical timing !!! Thanks a lot for the KMM series. I'm currently working on a big project which we want to migrate the business logic and data logic (if it's possible even VMs) into a KMM shared module, I would appreciate if you could dedicate an episode for implementing KMM with existing projects (android and iOS).

[@salvadorjohndeniel]

Me too it's for my thesis 😅

[@maskedredstonerproz]

seeing as how viewmodels usually contain conpose states, that might be...difficult, you'd have to have a dedicated viewmodel for the logic, and one for the compose states, something like MainViewModel for the logic(the one you will share), and a MainStateViewModel(the one for compose state you won't share), I personally think that's too much effort for no benefit because viewmodels are more associated with the ui than anything, and ui is something you don't share, besides, viewmodels tend to be specific to the way things are shown in the ui, which may not be the same on every platform

[@afixithei.V]

Wow... I haven't given KMM a try before but I so much love the logic behind it. I currently want to build a chat app with it and in the process will learn Swift

[@devOmarAZ]

We are all waiting. Thx Philipp ♥

[@MCStarYT]

Great introductory video. Can't wait for the next one. Keep up the good work 👏

[@theophilus494]

thank you soooooooooooooooo much... at least hope is rising gradually.. cos that's one of the reason I embraced Kotlin

[@thierrynkubito8580]

I've have learned a lot of of skills from you. be blessed and keep moving forward.

[@baijusharma6027]

That's going to be very interesting 👏👏👏👏

[@Soulcybering]

KMM is so interesting. Sharing viemodels is the most difficult and interesting topic. I just hope that compose ui will be released soon with iOS support

[@ChrisAthanas]

Dont hold you breath.... Apple is being very stubborn about any kind of cross platform tooling. They are literally like Internet Explorer from Microsoft from 2000-2016

[@TheThornTech]

Thank you so much! I'm waiting for the next lesson.

[@MatiasTesio]

Thank you for the video Phillip! Can you do a video about how to create and publish a KMP library that we can then use in an existing Android and iOS native apps? Thanks!

[@Subratsss]

Even same things i want

[@tmjromao]

Excelent Philipp! Will try to follow your insightnments and put mac mini to use :)

[@akashkumardas6521]

Thank you so much, you just make it simple.

[@ngolian]

Thanks for all your excellent videos. I'm really looking forward to watching the rest of this series. However, I think cocoapods is going to be a problem. I can't get cocoapods-generate installed, it's just dependency hell. I've had much better experiences with Swift Packages (SPM), and there seems to be a general trend of deprecating cocoapods in favour of SPM. There are some plugins to integrate SPM into KMM, so I'll be trying those instead. Perhaps you could investigate that and make some videos about it? I think that would be helpful to anyone interested in this series.

[@mahmoudh3sham]

Awesome Keep it up ♥

[@sovrinfo]

Thanks! Cool video!

[@gabrielbronzattimoro7953]

[@realcrys]

I had the brilliant idea of using a - in my shared module name :D That was the only hiccup. - translates to _ in the Swift import

[@4ytonly]

Wait! Does this mean, you can code swift in android studio????????

[@flowzk921]

Awesome!

[@SiamakAshrafi]

XCode 15 review does not have UIKit so, cocopods is old .... not sure if this is a good idea for the future. We build with Swift / SwiftUI / Swift structured concurrency / Swift package manager and know our iOS app will always be supported ...

[@charlitowashere5906]

do you think this will become a standard?? like some big companies launching huge apps for both platforms using KMM? competing with flutter? sounds amazing..

[@krystianwiewior8725]

It could be. KMM is improved. Flutter is very popular nowadays and it is really easy to build in both. One code.

[@SaifaldeenSAH]

So good video of KMM thanks

[@EntropicTroponin]

What bothers me the most is that you need an Apple PC to be able to develop for apple. Seriously Apple: why do you think a monopoly is okay when you do it?

[@deviantstudio]

i think initial reason was to save some cash. their crappy ide works only in their environment and they decided implementing cross-platform version from scratch would be expensive and technically complicated. then they converted this fail into marketing feature.

[@AIejandroide]

@@deviantstudio no, it's because they are greedy, and want you to buy their computers.

[@Yazon2006]

It's because people consume Apple shit with huge enthusiasm and say that this shit is extremely tasty.

[@afixithei.V]

It annoys me too.. at least they should let devs install a paid version of macos

[@avwie132]

There are tons of cloud services which provide compiling and creating iOS artifacts for Apple.

[@mikeshilovski1512]

At work we have 3 kmm projects and it's pain in the *** supporting it, and it still requires 2 developers to work on it. But I heard now ios part can be written in compose which is probably going to make it much easier

[@anudeepananth]

Hey Philipp, does jetpack compose lazy column support data from sql delight?

[@PhilippLackner]

[@David-im1fp]

Thanks for great video. I have been using windows for java development. For using android studio with kotlin and intellij IDE, which os (iOS or windows) should I choose for a new computer? Do these IDEs run on iOS as good as on windows? Thanks for advice.

[@kevinwestrom4775]

Is there a similar tool to Brew/Homebrew for the Windows OS?

[@NithinVargheseChalakkal]

thanks for the video ❤️ KMM or RN or FLUTTR ? Which one will be the preferred one in future? Jus a thought 💭

[@moldovanpeter5123]

Each have their own pros and cons :) do a research about this topic, and don't forget Xamarin which is still a thing but lacks devs and a good community.

[@deviantstudio]

we did such research a year ago and chose kmm. never regret. btw we even didn't consider RN as an option. it's not relevant in 2022

[@NithinVargheseChalakkal]

Seems like many companies moved to RN. Hope Kotlin will come back with KMM in future with support of 🍏.

[@Denis-gf6iq]

Yep all nice and good and thank you for the video, but in terms of cross platform anything beyond Hello World and or getting stuff from the web and displaying it on screen, any hardware integration like Bluetooth will quickly transform these cross platform projects into a huge pain. Native all the way.

[@PhilippLackner]

KMM is pretty much native but you need less code to write it. You have 2 separate code bases for native specific things that don't affect each

[@figurich]

I would like to see one day jetpack compose or swiftui can do web app perfect. Why bother too much between too very different company's native private garden? Most of the big app have their own shared cloud backend, so the ui part is the most cumbersome.

[@DevlogBill]

I've coded in the past, almost 1 year now with JavaScript. Do you have a video which explains in detail how to resolve issues when trying to run Koltin? I downloaded Android Studios as well as JetBrains intelliJ. I can't get none of them to run my Kotlin code, maybe I am creating the wrong file? I selected the console version. I even tried to run Kotlin on Visual Studio Code. I created a file called main.kt and after I created my main function and tried to run the code. I got an error message, "kotlinc: command not found" I am assuming that VS-Code is unable to compile the code?

[@vish1628]

can we also make web apps with it ?

[@k4ba]

There is hope for Kotlin against Dart and Flutter multi platform. So far I like more Flutter, I wish we had Kotlin instead of Dart :c

[@Daaaaaaavid]

I wonder about the target of KMM, I mean nobody wants to write an app twice but needing two IDEs and at the end needing iOS and Android knowledge to build the app doesn't sound really compeling, don't know how it is supposed to gain market share against for example Flutter.

[@PhilippLackner]

Flutter isn't native, kmm is. You therefore can't fully compare them

[@Daaaaaaavid]

@@PhilippLackner I know, but if you prioritize quality or have the resources I would stick with native iOS and Android, won't even use KMM, if I must prioritize resources then I won't go with KMM, I would go with Flutter.

[@deviantstudio]

in case of flutter you have to force your devs learn all the stuff from scratch. new framework, new libs, new (and crappy) language. also interop with native is a nightmare. while choosing kmm you continue to do mostly the same things. except business logic now shared and written in kotlin (which is a win itself). and coroutines! also data models layer could be shared with backend. also you can use jetpack compose which will be ported to ios in near 2 years, and already works fine on desktops.
