I'm trying to get our CI working to build our own machine image AMI descriptions. Part of that is to download the correct runtime versions so that we can pre-create the simulators we use for testing on these machine image descriptions.
When running the code like
xcodebuild -downloadPlatform <platform> -exportPath "$<temp_folder_path>"
Locally I get a result and download a runtime, but on CI I just get All available platforms are downloaded. Why is this message happening and how can I specify specific platforms to download over CI to configure our machine setup?
