Xcode 26.4 won't install simulators, just spins the beachball

Something happened with my Xcode 26.4 install, I've never had this happen before. I get Xcode 26.4 installed, but the simulators aren't installed. And nothing pops up to "install required simulators".

In Devices & Simulators I click the + to install a new simulator, and the beachball just spins and Xcode becomes unresponsive.

I've tried quitting and restarting Xcode, reinstalling it (using both xcodes command line tool and the app store), removing Xcode and reinstalling, rebooting after removing Xcode and before reinstalling.

Not sure what to try next. Feels like something is left over from uninstalling that's hanging it up. But I've no idea what.

I could use some Apple Xcode team help here.

Please looks at this thread https://developer.apple.com/forums/thread/818209?answerId=879540022#879540022 where the Apple DTS engineer went over the terminal scripts

if you don't mind trying in the terminal

% curl -v https://gdmf.apple.com

% curl -v https://download.developer.apple.com

% curl -v https://devimages-cdn.apple.com

Let us know if that fixes your issue and the issues from those commands.

Additional: It won't launch an app on my phone either. (No changes to the app, and it would launch in sim or phone before the failed update of Xcode.)

It's just spinning in "Launch" phase of the build.

@mhteas Seems very strange to me. There are many posts in the forums about downloading simulators. I would recommend to do a quick search. However not launching the app is concerning. I would like to see a few things but for that I need to ask you for the sysdiagnose. I think I should ask you to file a bug so we can collect that with privacy in place.

Once you open the bug report, please post the FB number here for my reference.

If you have any questions about filing a bug report, take a look at Bug Reporting: How and Why?
