Xcode 27 Device Hub, no option to view Point Accurate and Pixel Accurate window sizes
Hi, On Xcode 27, Device Hub, how to view the simulator with Point Accurate and Pixel Accurate window sizes? These are existing options on Xcode 26 Simulator, so would be nice to have them in Xcode 27 Device Hub. This would be needed sometimes to quickly measure things using a on screen ruler. Feedback FB23033231 If there is no option currently can you please provide options to provide to view Point Accurate and Pixel Accurate window sizes

Device Hub unexpectedly quit
I have raised Feedback FB23036084 Just using it on an extremely small app that display six SwiftUI charts. I was just scrolling on a ScrollView of the charts. Th feedback has a link to the app on GitHub, the content of the generate report details and also the output of running xcrun simctl diagnose

Recording app audio from Device Hub
It appears that recording video of a device in Device Hub does not record the associated audio of the device. Are there any plans to do this? (Or a workaround that's easier than rerouting the audio output to an audio editor app and recording it separately?) It would be incredibly useful for making app demonstrations and tutorials.

What is the logic for when the Enter Resize Mode button is enabled in the Device Hub?
This button is enabled for new projects I've created in Xcode 27, but I haven't been able to see it in a not grayed-out state with any of my existing projects created with prior versions of Xcode.

How to simulate two-finger touches in the Device Hub?
My app relies on two-finger tap for some interactions. This was easy in the old simulator by holding down option while clicking. Is there an equivalent interaction in Device Hub? (Option-click no longer seems to work.) If not, will this be added back in a future beta?

Device Hub Breaks on use
Hi, whenever I build my app to a simulator it launched device hub but then nothing, makes my Mac extremely hot and cause fans to engage all for nothing. Is it because I'm still on MacOS 26.5.1? Just seems like device hub is broken for me I can only launch testing on physical devices.
