Hello, is the issue still persisting for you and are you able to trigger other simulators to download?

If the problem still occurs, could you send us a feedback report and attach a sudo sysdiagnose to help our analysis? thank you!

I wanted to follow up on my previous message regarding the simulator download issue in the latest Xcode. I’ve already provided all the requested details, but I haven’t received any update yet. To be honest, I’m becoming increasingly frustrated with the lack of response and progress. This issue has completely blocked my development work — I’m unable to run or test any iOS projects until this is resolved.

Are there any updates? Does Apple offer developer support?

I have sent numerous emails to devprograms @apple.com, yet they have not responded. Despite paying the annual fee, we still lack support from them.

I've tried downgrading Xcode to version 16, but I'm still encountering the same issue

Why don't you offer simulator downloads on the website? It would make our lives so much easier.
