# compose-ios

[Anshulupadhyay03]

Hi Guys...I am new to the kmm world and trying to learn kmm. I am trying to run/build my first compose Android+ ios app using kmm. However, i am getting strange errors when i run the ios app. The Android app works fine. I have not added any compose-related code in the iosApp as I wanted to check if everything works fine after adding compose-related dependencies in commonMain. The strange thing is that this error goes away when I comment the compose-related dependency in common main section of the gradle file. I am able to run ios app for other compose-multiplatform tutorial apps. Can anyone point the issue?

gradle file

plugins {
    kotlin("multiplatform")
    kotlin("native.cocoapods")
    id("com.android.library")
    id("org.jetbrains.compose")
}

kotlin {
    android {
        compilations.all {
            kotlinOptions {
                jvmTarget = "1.8"
            }
        }
    }
    iosX64()
    iosArm64()
    iosSimulatorArm64()

    cocoapods {
        summary = "Some description for the Shared Module"
        homepage = "Link to the Shared Module homepage"
        version = "1.0"
        ios.deploymentTarget = "14.1"
        podfile = project.file("../iosApp/Podfile")
        framework {
            baseName = "shared"
        }
    }

            }
        }
        val commonTest by getting {

the error i am getting is

Make your Cocoapods Framework static See Compose-Multiplattform-templates:

framework{
baseName=…
isStatic=true
}
