@okwasniewski any chance of this getting merged & released soon? I've always used MiniSim and it would be sad when it wouldn't work with the new Device Hub.

+1 to this, iOS sims not working in last xcode version

@PaitoAnderson Thanks for this — I hit the same Xcode 27 breakage and can confirm the whole approach works on real hardware (Xcode 27.0, macOS 26, iOS 27.0 runtime):

• Contents/Developer/Applications is fully removed and no Simulator.app exists anywhere in the Xcode bundle or the simulator runtime cryptex; Device Hub ships at Contents/Applications/DeviceHub.app with bundle ID com.apple.dt.Devices and the devices URL scheme registered in its Info.plist.
• open "devices://device/open?id=<udid>" launches Device Hub, boots a shutdown device, and focuses its window — verified end-to-end, so the deep-link targeting is solid.

I opened #156 on top of this PR with one hardening: falling back to open -a DeviceHub.app when the devices:// scheme isn't in the LaunchServices database yet (fresh installs), so users get Device Hub opened instead of an error dialog. Happy to close it if you'd rather fold the change in here.

Thanks @Alarak-Alex! Maybe best to just leave both PRs open and maintainer can decide how to best merge? I'm good with anything :)
