I'm unable to use the iOS 27 runtime in Xcode 27 beta 1. It appears uninstalled, but has no Get button, so I can't delete it, nor uninstall it. Using the Get button in the toolbar results in "Fetching download information..." forever. When I click info and copy information, it says "iOS 27.0 beta (24A5355p) SDK + Simulator (Components absent)." It doesn't show up in any of the xcrun simctl commands for listing devices or runtimes. It doesn't show up in the Add Platforms modal. I was unable to debug this issue with an Apple engineer in person, so they suggested I post here!

Update: xcodebuild -downloadPlatform doesn't work either, even though it does for watchOS

I was able to resolve the issue by specifying an architectureVariant; without one specified, it defaulted to universal, but couldn't find one to install. I realized this when I tried to the same command for watchOS, and it default to arm64.

xcodebuild -downloadPlatform iOS -architectureVariant arm64

I can confirm that I also have the same issue with Xcode 27 Beta 1.

There is no Get button to download the iOS 27 runtime.

However, I have not been able to find a workaround or fix to the problem.
