Quick question about KMM XCFramework builds.
By default, Kotlin generates all architectures (arm64, arm64-simulator, x86_64), which is great for compatibility but slows down CI a lot.
Has anyone here configured the build to generate only arm64 for CI?

or ./gradlew sharedembedAndSignAppleFrameworkForXcode does it by default only arm ?

I think you can just comment out the unnecessary architecture from shared gradle build

???

[Ollaom]

what is your point?

I think if you search this slack this has already been answered before but what Rizwan is saying is that you can also exclude architectures yourself if you wanted with something like

listOfNotNull(
        iosArm64(),
        iosSimulatorArm64().takeUnless { YOUR_RUNNING_IN_CI_FLAG },
    ).forEach { iosTarget ->
        iosTarget.binaries.framework {
            baseName = "Shared"
            isStatic = true
        }
    }

in your gradle script.

From memory there are already some optimisations that the Kotlin team has built in tho

sir how about this

val frameworkName = "shared"
    val xcf = XCFramework(frameworkName)
    targets.filterIsInstance<KotlinNativeTarget>()
        .forEach {
            it.binaries {
                framework {
                    baseName = frameworkName

                    val includeToXCF = when (project.activeArch) {
                        Arch.ARM -> {
                            this.target.name.contains("iosArm64") || this.target.name.contains("iosSimulatorArm64")
                        }

                        Arch.ARM_SIMULATOR_DEBUG -> {
                            this.target.name.contains("iosSimulatorArm64") && this.debuggable && !this.optimized
                        }

                        Arch.X86 -> {
                            this.target.name.contains("iosX64")
                        }

                        Arch.ALL -> {
                            true
                        }
                    }

                    if (includeToXCF) {
                        xcf.add(this)
                        logger.lifecycle("framework '${this.name}
