Hi @Claude31, thanks for the response. Just updated to Sequoia (15.2 (24C101)) but the issue persists. I completely reseted my iMac to its default settings, downloaded it from the official website again, simulators were downloaded without a problem, however, when it comes to previewing, nothing happens. It just keeps spinning, as shown in the OP. I even enabled Legacy Previews, but it didn't seem to work.

@Developer Tools Engineer As for your question: To verify that the simulators work outside of previews on your system could you attempt a build+run of your app ⌘+R ? If that works [...] Well, I think it didn't work? This popped up after I pressed ⌘+R, subsequently after it showed 'build succeeded': I'm new to Xcode (this is literally the first time I'm (trying) to code using SwiftUI). I checked on Xcode > Settings > Components to see if there's something wrong, but apparently everything's fine. Is there something else I could do?

Oi! Usuário do Brasil aqui. Você já tem o D.U.N.S. e quer criar a conta corporativa, ou deseja primeiro criar a conta individual (pessoa física)? Se você puder colocar um print das etapas, ou erros, ia ajudar muito.

To use TestFlight to test your app link in Xcode, you need to first create a build archive of your app, then upload it to App Store Connect through Xcode, selecting "TestFlight" as the distribution method; this will allow you to share the app with testers through a link that they can access on their iOS devices via the TestFlight app.

Did you receive an e-mail from Apple confirming your purchase?

Same happened to me. https://forums.developer.apple.com/forums/thread/771428 Let's boost so Apple will fix this.

The same happened to me (https://forums.developer.apple.com/forums/thread/771428) Did you find a workaround? I can't seem to find it anywhere and I can't code because I can't preview and simulate my app. This is really a bummer.

The same happened to me using Xcode 16.2 on Sequoia. I've posted here but didn't get a solution. Did you find a workaround?

The same happened to me. Did you find a fix to this problem?
