[Kavita]

Hello everyone,
I just have started exploring Kotlin multiplatform and created the Hello World! project. I can run the Android project on emulator but I don't see the option to run the iOS app. Even iOS simulator option is also not visible. I must have missed something.
How to run the iOS app in Kotlin Multiplatform project?
Can someone please help me to solve this query?

[Kris Wong]

see the iOS Application template under Run Configurations

[Kavita]

Hi @Kris Wong,
Yes, it is there but nothing happens after clicking on it

[Kris Wong]

oh that's quite odd. something seems amiss with your KMM plugin

[Kavita]

[Kavita]

We need to install xcode for this, right?

[Kris Wong]

maybe try removing it and re-adding it, and restarting android studio

[Kris Wong]

yes you have to have Xcode & command line tools installed to work with iOS apps

[louiscad]

Could be worth filing an issue on kotl.in/issue to have KMM warn noticeably for iOS run configurations when Xcode and its command line tools are not installed.

[Kavita]

I just have installed Xcode 11 but not command line tools.

[louiscad]

Just open Xcode, it should take care of it before the welcome window appears.

[Kavita]

I just have created a new project & I am able to run it in xcode.

[louiscad]

Now, running it from Android Studio with KMM should works as well.

[Kavita]

Still the same issue

[louiscad]

Did you try clicking +?

[Kavita]

Yeah @louiscad, tried that as well. Seems not able to add the template

[Kavita]

Is it because I had installed Multiplatform plugin first and then xcode?

[louiscad]

I'd first try to just restart the IDE. BTW, are you using Android 4.1+? If not, please try with 4.1 or 4.2

[Kavita]

I tried by reinstalling Multiplatform plugin & restart the studio. Didn't work :(
Below are the versions:
Android Studio version: 4.0.1
Kotlin plugin version: 1.4.10-release-Studio4.0-1
Multiplatform: 0.1.3-release-54-Studio4.0

[Kris Wong]

I had this working with those versions ¯\_(ツ)_/¯

[louiscad]

AS 4.0 is not really supported anymore from KMM 0.1.3 onwards.

[Kavita]

You are right, seems I need to update studio & xcode as well. I had installed xcode11, as per the documentation it supports 11.3+

[Kavita]

Thanks a lot @louiscad & @Kris Wong for the quick help 🙂

[louiscad]

Can you report the fact that KMM didn't warn you about all that on kotl.in/issue and give us the link? That'll be helpful for others in the future.

[Kavita]

Right, I can do that 👍

[louiscad]

Then please do, I'd like to upvote it.
Also, can you confirm it works on Xcode 11.3+ or Xcode 12.x?

[Kavita]

@louiscad I have reported the issue:

[Konstantin Tskhovrebov]

https://plugins.jetbrains.com/plugin/14936-kotlin-multiplatform-mobile/versions/stable/98571

This version requires Kotlin Plugin: 1.4.10-release-1-Studio4.1-1

[louiscad]

Ah yes, @Kavita, you probably need to update the Kotlin plugin, 1.4.0 is not the latest release.

[Kavita]

Could you please provide me the details of Studio & plugin versions, which u are using in the Multiplatform project? I can try similar versions, maybe that will help.

[Konstantin Tskhovrebov]

Check your xcodeproj property in gradle.properties file please

[Kavita]

@Konstantin Tskhovrebov it is xcodeproj=./iosApp

[Konstantin Tskhovrebov]

Maybe some errors in sync console during gradle sync?

[Kavita]

No, it worked smoothly.
No error in an event log, just these 2 warnings:

12:38 AM	Plugin Update Recommended: Android Gradle Plugin is ready to update.

12:38 AM	Plugin Update Recommended: Android Gradle Plugin is ready to update.

[louiscad]

@Kavita Can you try the "Build" tool window?

[louiscad]

Also, can you ensure you performed a Gradle sync first? (The elephant + tilted arrow icon in the toolbar)

[Kavita]

Yeah, I performed gradle sync. It worked without error

[louiscad]

The project doesn't include private code yet, right? If so, I think it could be zipped and sent to @Konstantin Tskhovrebov so he can check if the culprit lies in the project or in your machine config.

[Kavita]

Yeah, this will be really helpful as I have spent 2-3 days on installing and trying multiple plugin versions. It is the default Hello world project. I can share it.

[louiscad]

Another way is one of us sharing a project that works on our machine, freshly created from the wizard.

[Kavita]

When I build the project, I got this error:

[louiscad]

Can you click on the root element in the run window to see all the logs?

[Kavita]

Awesome, this solution worked 🤩 . I applied the changes & restart the studio.
Thanks @Konstantin Tskhovrebov & @louiscad for all the help 🙏
