Floating Simulator Window Stops Appearing

[AvdLee]

Summary
The RocketSim floating window intermittently stops appearing around the active iOS Simulator window. Once this happens, toggling the feature, restarting the Simulator, or re-launching RocketSim does not restore the overlay.

Environment
• RocketSim 14.5.0 (295)
• macOS 26.2 (Build 25C56)
• Apple Silicon (arm64)

Observed Behavior
• Floating window does not appear around the Simulator.
• Issue persists across:
• Toggling the floating window off/on
• Restarting the Simulator
• Logs repeatedly show failures resolving the active Simulator window.

Relevant Logs

SimulatorWindowMonitor.swift:L276
ERROR: activeWindowMissing
Could not determine active simulator window ()

This error occurs repeatedly across multiple sessions and timestamps.

Expected Behavior
• RocketSim should reliably detect the active Simulator window and display the floating overlay when enabled.

Notes / Hypothesis
• SimulatorWindowMonitor appears unable to resolve an active Simulator window once it enters this failure state.
• Possible edge cases:
• Simulator window focus changes
• Detached / minimized / multi-window Simulator setups
• Window identity caching not recovering after failure

Reproduction
• Not consistently reproducible, but once triggered the issue persists until a full reset (unclear which action restores it).

Hey @AvdLee I have never been able to get the side window to appear. I haven't spent any time debugging yet, but my assumption is related to non-standard locations. Xcode runs on an external NVME volume, and my build artifacts do as well.

Is there a way I can reset and force onboarding again?

When digging through logs, i could only find one helpful clue

Error Domain=NSCocoaErrorDomain Code=4 "The file “simctl” doesn’t exist." UserInfo={NSFilePath=/Volumes/nvme/Applications/Xcode.app/Contents/Developer/usr/bin/simctl} [Refreshing open simulators failed]

That file path does actually exist so it seem clear this is a permission issue. I'm not able to get the system to prompt for permissions and even more odd, there isn't even an entry for RocketSim under the privacy section for "Files & Folders", which i would expect an entry for Removable Volumes. My suspicion is that during onboarding i set my DerivedData/archives to the default host location, which is incorrect, but more importantly never triggered the access prompt for removable volume. I don't see a way to configure that through config, and looks like those user preferences are sticky across installs. I want to force onboarding again just to test some of these assumptions.

If that file operation was actually related it actually would have been extremely helpful if that exception was allowed to raise. There is no indication that anything was wrong so I just assumed I had no idea how to actually use the product and said i'll come back to this another day and read the docs. I'm coming back to it 6 months later and after reading the docs, was even more confused, because I assumed it had to be user error/confusion because it was so quiet, no hints anything was wrong and figured toggling "floating windows" must be intentional NOOP because i'm using it wrong.
