Hello, @b.n.ch. I had the same issue, but realized what was happening: all the simulators that I tried to create in Device Hub were being run in the old Simulator app. I solved this very quickly by simply rebooting my Mac. Then, all the simulators I created appeared in the Device Hub.

[quote='892762022, midnight beep, /thread/831301?answerId=892762022#892762022, /profile/midnight+beep'] Apple Intelligence Writing Tools has disappeared on my Mac running 27b1 after enabling Siri AI. Is this a known issue? [/quote] Although it isn't very clear at all, I believe that Writing Tools has actually been completely replaced with Siri AI and the new "Write With Siri" feature. Write With Siri automatically proofreads your text as you write it, so that would replace the "Proofread" tool. Everything else would be replaced by Siri AI. With on-screen awareness, Siri can now (in theory) be used to change whatever you're writing. If I am correct, you should now be able to say, "Hey Siri, make this sound more friendly" or "Make this more concise," thus rendering Writing Tools unnecessary and allowing Apple to remove them. Although (as to the extent of my knowledge) Apple did not explicitly state that Writing Tools will be integrated with Siri AI, not only would it be a huge oversight to have them be completely missing in iOS 27's beta, but also they did not even appear in the WWDC26 Keynote and appeared to be replaced with Siri AI in Apple's demos.

Hello, @jouzas! This website is one for those who develop applications for Apple products to ask questions and get help from fellow developers or Apple Engineers. It looks like you're trying to submit feedback, so highly recommend that you instead submit this through Apple's official iPhone Product Feedback page.

Thank you, @reed.1325 and @l00! I rebooted my device, and Device Hub is now working. I realized, by the way, that the simulators I created in Device Hub were being created in the Simulator app. Hopefully this gets fixed in the next beta
