How to Download IOS 26 beta runtime simulator using "xcodebuild" tool?

How to download the runtime simulators for the most recent Xcode 26 beta? The current download command I’m using doesn’t seem to work, and I’m encountering the following issues:

The runtime simulator download command (xcodebuild) requires the version number to be specified explicitly. I’ve tried multiple variations of version names/numbers but haven’t been able to identify the correct naming convention used by Apple for the Xcode 26 beta simulator runtimes.

$ xcodebuild -downloadPlatform IOS -exportPath ~/Downloads -buildVersion 26 Finding content...iOS 26 is not available for download.

$ xcodebuild -downloadPlatform iOS -exportPath ~/Downloads -buildVersion 26.0 Finding content...iOS 26.0 is not available for download.

$ xcodebuild -downloadPlatform iOS -exportPath ~/Downloads -buildVersion 26.0 beta Finding content...iOS 26.0 is not available for download.

$ xcodebuild -downloadPlatform iOS -exportPath ~/Downloads -buildVersion "26.0 beta" Finding content...iOS 26.0 beta is not available for download.

$ xcodebuild -downloadPlatform iOS -exportPath ~/Downloads -buildVersion "26.0_beta" Finding content...iOS 26.0_beta is not available for download.

$ xcodebuild -downloadPlatform iOS -exportPath ~/Downloads -buildVersion 26.0_beta Finding content...iOS 26.0_beta is not available for download.

Hi, does selecting the Xcode 26 beta and then running xcodebuild without the buildVersion work for this situation? Could you also send us a bug through the feedback request. Thank you!

sudo xcode-select -s <pathTo/Xcode26-Beta.app>
xcodebuild -version 
xcodebuild -downloadPlatform iOS -exportPath ~/Downloads/
