The SDKs for all of Apple's platforms are included in the main Xcode XIP image. By SDK here, I mean the textual files for the API interfaces, like header files and other supporting content. You can see them all if you peak inside the Xcode bundle under Xcode.app/Contents/Developer/Platforms/.platform/Developer/SDKs. What you need to download isn't the SDK, it's the platform support components, which includes the simulator. While you always have the textual SDKs, you can't run a build without installing the platform support components, as they are used during the build process. So while you aren't downloading installing the textual part of the SDK content, the large extra component download enables builds using that SDK. You found the right documentation article, and you want a command like this: xcodebuild -downloadPlatform iOS -exportPath ~/Downloads That will give you a DMG file, which you can then also install through the command line over night in your data center with: xcodebuild -impor
