Working in Kotlin Multiplatform project with Cocoapods dependency.

These are the build output log

** BUILD FAILED **

The following build commands failed:

(1 failure) warning: Run script build phase ‘Compile Kotlin Framework’
will be run during every build because it does not specify any
outputs. To address this warning, either add output dependencies to
the script phase, or configure it to run in every build by unchecking
"Based on dependency analysis" in the script phase. (in target
‘iosApp’ from project ‘iosApp’)

The Cocoapods scripts in build.gradle.kts

cocoapods {
        version = "1.0.0"
        summary = "Some description for the Shared Module"
        homepage = "Link to the Shared Module homepage"
        ios.deploymentTarget = "16.0"
        podfile = project.file("../iosApp/Podfile")
        framework {
            baseName = "composeApp"
            isStatic = true
        }

        // Maps custom Xcode configuration to NativeBuildType
        xcodeConfigurationToNativeBuildType["CUSTOM_DEBUG"] = NativeBuildType.DEBUG
        xcodeConfigurationToNativeBuildType["CUSTOM_RELEASE"] = NativeBuildType.RELEASE
    }

Appreciate if there is any help or clue, how I can solve this.
Note : it works fine for Android simulator

Well the error here:

‘/Users/andrea/Folders/KMP/ComposeWeather/iosApp/../shared/build/xcode-frameworks/Debug/iphonesimulator17.2’ not found

Can you check if you have the simulator device installed (the target device you are deploying to)?

And can you also check if you have iOSX64 target set properly on your shared module’s gradle file?

You should have something like this:
```
kotlin{

  iOSArm64()
  iOSX64()

  commonMain(){

  }


  val x64 = iOSX64 by getting
  val arm64 = iOSArm64 by getting

  iOSMain(){
      dependsOn(commonMain)
 
      // makes sure all iOSMain source sets are compiled into target folders
      x64.dependsOn(this)  
      arm64.dependsOn(this)
  }
}
```
With x64 devices you should only be able to target rosetta simulators.

For example: iPhone 14 (Rosetta).

With simulatorArm64 you should be able to target non rosetta
