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 RUclips and soooo helpful. Hope this reaches you and we see a video on that soon. Cheers!
Great video! I'm also a RUclipsr so I would recommend you to edit the closed captions via RUclips Studio > Content > video Details > Subtitles > Duplicate and Edit the Automatic Subtitles > Edit incorrect words like Japan vs Jetpack > Publish > Thanks for the excellent video!
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!
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.
@@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.
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!
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!
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.
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
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.
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
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
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
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).
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
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 ...
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..
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
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.
Hey I am getting this error -> ✖ Xcode requires to perform the First Launch tasks Launch Xcode or execute 'xcodebuild -runFirstLaunch' in terminal. Any help?
I got this error when running kdoctor: Xcode requires to perform the First Launch tasks. I am not sure why though and I have accepted all licenses for xcode.
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.
Would you focus on the Swift UI part on this Playlist? I think it's the powerful part of KMM but also a big disadvantage for Android or IOS developers to stay up to date with all the newest things of Jetpack compose and Swift UI
Hey Philipp, i am new with Kotlin i was wondered if its possible build a full functional app using only kotlin programming language...if possible as kotlin multiplatform mobile application...thanks
I was using xcode14.0.1 and macos Monterey; when I run kdoctor, I get the message: * Xcode requires to perform the First Launch tasks Launch Xcode or execute 'xcodebuild -runFirstLaunch' in terminal However, I have launched the xcode and ran the startup app; I still get the same message; i can. not find xcodebuuild on my mac ...
Hallo Philipp konntest du mir bitte antworten, damit KMM app machen die laptop muss MacBook Sein? weil, wir sind benutzen Ios auch , sondern Ios geht nicht mit windows systesm. Konntest du antworten damit, herzlichen Danke dir zu vor
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.
I've got a problem with cocoapods, had to instal ruby 2.7, but didn't solve the problem. Now i have ruby 2.7 installed but still getting the error that i have to install it
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?
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.
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?
I have a M1 mac mini 2020. No matter what i do, can`t install cocoapods-generate, always "cocoapods-generate plugin not found". tried to "sudo gem install cocoapods-generate" and nothing.
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.
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 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.
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.
Hello everyone, If app is not running on iOS after following all the steps make sure to have java version 17+ I had 16 and I couldn't run the app without any errors. Just the "shared" was always unknown.
Kept getting "you are using java 1.8 you need 11 etc." when trying to run the ios version, had it set to 11 in AS but still wouldn't compile, finally solved it by adding org.gradle.java.home=/Applications/Android Studio.app/Contents/jre/Contents/Home to gradle.properties
Hello! For Windows (and Android only) you just need to install plugin: Kotlin Multiplatform Mobile, restart Android Studio and create new project (Kotlin Multiplatform App). If you want both (iOS and Android) you will need to install virtual machine (like VMware ) to use XCode.
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.

KMM or RN or FLUTTR ?
Which one will be the preferred one in future? Jus a thought 💭
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.
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
Seems like many companies moved to RN. Hope Kotlin will come back with KMM in future with support of 🍏.
I have an Android project with library written in Java. Should I convert the Java libraries to Kotlin before run the project on iOS?
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
I don't have a Macbook I hope I can do this in my windows, any suggestion?
What about job market for these implementation? Do you have any idea?
😍😍😍😍 please continue I am very happy to see that.

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

There are tons of cloud services which provide compiling and creating iOS artifacts for Apple.
That's going to be very interesting 👏👏👏👏
