Can't run commonTest on iOS simulator

[dima-avdeev-jb]

When trying to run test from commonMain in iOS simulator:

Test fails with error:

Undefined symbols for architecture arm64:
  "_OBJC_CLASS_$_MTLCommandBufferDescriptor", referenced from:
      objc-class-ref in libskia.a(gpu.GrMtlCommandBuffer.o)
 ...

I've also came across this issue (Apple M1 Pro)

Here's my repository branch to reproduce this issue: AKJAW/Kotlin-Native-Implementations@03420e6

Besides the

Undefined symbols for architecture arm64:
  "_OBJC_CLASS_$_MTLCommandBufferDescriptor", referenced from:
      objc-class-ref in libskia.a(gpu.GrMtlCommandBuffer.o)
  "_OBJC_CLASS_$_MTLCompileOptions", referenced from:
      objc-class-ref in libskia.a(gpu.GrMtlUtil.o)
  "_OBJC_CLASS_$_MTLDepthStencilDescriptor", referenced from:
      objc-class-ref in libskia.a(gpu.GrMtlDepthStencil.o)
...

I'm also getting a lot of warning for skia being built for a newer version:

e: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ld invocation reported errors

The /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ld command returned non-zero exit code: 1.

To fix this issue, I needed to comment out the following libraries:

        val commonMain by getting {
            dependencies {
                implementation(compose.runtime)
//                implementation(compose.foundation)
//                implementation(compose.material)
//                @OptIn(org.jetbrains.compose.ExperimentalComposeLibrary::class)
//                implementation(compose.components.resources)
            }
        }

when

cocoapods {
    ..
    framework {
        ..
        isStatic = false

I also get this issue. Any timeline on when we can set this value to the default (false)?

Are there any fixes / workarounds for this issue? Being unable to run iOS tests is a big issue for the Shared codebase

[pjBooms]

Yes it is fixed in the 1.5.0-beta01

For previous versions look at this workaround: https://github.com/JetBrains/compose-multiplatform/pull/3378/files
