Add ios target for using library with Compose for iOS

[VitalyPeryatin]

Add ios target for using library with Compose for iOS. It is impossible to use these dependencies in project with Compose for iOS without this target:

• koalaplot-core

[gsteckman]

Hi, I've added the ios() target and updated the GitHub actions to build on MacOS. However, there is a build error. Unfortunately, I don't have a Mac so I cannot troubleshoot the problem locally, and it took the runner almost 10 minutes to get to the point where a missing symbol was found.

If you have a Mac, could you help find the problem?

Link to the build log with the error

@gsteckman can you please try your ci pipeline without commonTest folder?
I have thought thats this maybe a problem with dependencies linking in iOS framework in commonTest source during compiling iOS target. I tried to reproduce the problem and it does not appear only if i remove this folder. I cannot figure out how to fix this concrete problem yet, but it worked for me.

This can be starting point for debugging overall problem

Hi again @gsteckman !
Also see this issue JetBrains/compose-multiplatform#2342

Please try to add
kotlin.native.cacheKind=none
in your gradle.properties and try building project with ios() source set

[gsteckman]

I merged the PR from @jakepurple13 which includes the cacheKind property. But the builds are still failing due to undefined symbols during linking. There are a lot of warnings of mismatched versions for the simulator, which may be the root cause of the undefined symbols. The odd thing is in the latest commit I removed the iosSimulatorArm64() target, but it is still causing errors, see log for version 11 vs version 9.

When I left iosSomulatorArm64() in, it was version 15.2 vs version 9 - see log.

Any ideas where these version numbers are coming from? I tried searching and looked at some of the Kotlin multiplatform examples, but didn't see any ios specific version information in the build files.

Hello again @gsteckman. I'v created PR with fixes, which helped me to assemble all library artifacts and sucessfully use your library in compose multiplatform #16

Is there a way to get a snapshot build of the repo? JitPack doesn't seem to work anymore.

Hi @zacharee.

I'm still waiting for @gsteckman to publish a new release with latest fixes.
For now i'm publishing Koalaplot artifacts to mavenLocal() with publishToMavenLocal gradle task and building my project this way.

[gsteckman]

Hi @zacharee, I published a 0.4.0-dev1 build with ios artifacts. Please let me know if they don't work ok for you. I don't own any Apple devices so can't test them. Thanks to @maltsev-gorskij for helping to get the ios build working.

[zacharee]

I tried it, but it doesn't look like iOS artifacts got generated/uploaded. Gradle fails to sync because it can't find the ones for iOS.

[gsteckman]

I see them in search results at https://central.sonatype.com/search?q=koalaplot, and also can see the files at https://repo1.maven.org/maven2/io/github/koalaplot/.

What is the specific error you are getting?

[zacharee]

I tried again and it's syncing now ¯\_(ツ)_/¯. I'll open a new issue if there are problems with functionality on iOS.

No problems. Glad to help ;)

P.S. Thanks for release!
