Kotlin Multiplatform: Execution failed for task ':shared:linkDebugFrameworkIosSimulatorArm64' [duplicate]

Question

When trying to build a Kotlin Multiplatform App for iOS (from both Xcode and Android Studio), an error returns regarding the linkDebugFramework and the PhaseScriptExecution run script.

This stacktrace is output:

> Task :shared:linkDebugFrameworkIosSimulatorArm64 FAILED
error: /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.
output:
ld: unknown options: -ios_simulator_version_min -sdk_version 
error: Compilation finished with errors

FAILURE: Build failed with an exception.

** BUILD FAILED **


The following build commands failed:
    PhaseScriptExecution Run\ Script /Users/[user]/Desktop/[app]/build/ios/[app-name].build/Debug-iphonesimulator/[app-name].build/Script-7555FFB5242A651A00829871.sh (in target '[app-name]' from project '[app-name]')
(1 failure)

So far, I have tried:

• Setting xcodebuild command line version
• clearing iOS build folder
• reinstalling xcode and android studio
• clearing gradle cache, rebuilding gradle

What worked for me was updating my build.gradle.kts to include:

id("com.android.application").version("8.1.0").apply(false)
    id("com.android.library").version("8.1.0").apply(false)
    id("com.google.android.libraries.mapsplatform.secrets-gradle-plugin").version("2.0.1").apply(false)
    kotlin("android").version("1.9.10").apply(false)
    kotlin("multiplatform").version("1.9.10").apply(false)
    kotlin("plugin.serialization").version("1.9.10").apply(false)

Downgrading xcode did not work.

You're probably using Xcode 15 and an older version of Kotlin. If on Xcode 15, bump Kotlin to 1.9.10. Alternatively, install Xcode 14.3.1.
