Answer 1

It's 2022 and the issue is still happening on the default project that gdx-setup creates for iOS. I fixed the problem by changing the following line in build.gradle of the main module:

project(":ios") {
    apply plugin: "java-library"
    apply plugin: "robovm"

    dependencies {
        implementation project(":core")
        api "com.mobidevelop.robovm:robovm-rt:$roboVMVersion"
        api "com.mobidevelop.robovm:robovm-cocoatouch:$roboVMVersion"
        // api "com.badlogicgames.gdx:gdx-backend-robovm:$gdxVersion"
        implementation "com.badlogicgames.gdx:gdx-backend-robovm:$gdxVersion"
        api "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-ios"
        api "com.badlogicgames.gdx:gdx-bullet-platform:$gdxVersion:natives-ios"
        api "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-ios"
        
    }
}

I had the same issue. Maybe the cause is different because I am replying in 2021 while this issue is from 2014

Anyway, in my case in the build.gradle file I replaced the 'implementation' for the 'api' when importing the libraries causing the issue. This solved the problem
