Thank you for the post, are now the simulators downloaded? Have you followed the recommendation to download those using Xcode?
Do you have more than one Xcode installed? It is highly likely that either the system is still pointing to the older Xcode version, or the Simulator Runtime itself hasn't been fully registered by CoreSimulator.
Device Hub uses the active Xcode path to determine which simulators are available. Even if you installed the Command Line Tools for Xcode 27, the system might still be pointing to your stable Xcode 26.5 installation.
Open Terminal and check your current path with, I think is that command.
xcode-select -p
Can you provide me what do you see when you go to the Xcode simulator list? I believe a developer already provided this suggestion?
- Open Xcode 27 Beta.
- Go to Xcode > Settings > Platforms.
- Ensure that iOS 27.0 Simulator is listed and fully downloaded. If there is a "Get" button next to it, it hasn't been downloaded yet.
Look for iOS 27.0 in the output, it will usually give you a reason why (e.g., missing dependencies or incompatible macOS version)?
If you go through these steps and xcrun simctl list runtimes what does it show?
Looking forward to get your answers so we can figure it out. Many developers here will be able to help with more suggestions.
