xcode15.1 preview is not loading
Hi,
Sorry to hear you are having problems getting previews working. This error can often indicate a crash in your application when it launches, or a problem with the simulator. If you look into the folder ~/Library/Logs/DiagnosticReports, do you see any crash reports for your app?
If not, the best next step will be to file a feedback with diagnostics so we can take a look.
Steps to generate helpful diagnostics:
- Download and install the logging profile on all devices involved. Instructions and profiles are available here: https://developer.apple.com/bug-reporting/profiles-and-logs/?name=swift
- Reproduce the issue
- Click the "Diagnostics" button in the error banner in Previews' Canvas area (or if the banner is missing you can use the menu: Editor > Canvas > Diagnostics)
- In the sheet that appears, click "Generate Report" in the bottom left of the sheet
- Attach (or make from the folder) the resulting zip file to the bug (will be named something like
previews-diagnostics-0123456789.zip) - Generate the sysdiagnose(s) and attach those too
Same issue on Xcode 15.2 using Sonoma 14.2, When i try to preview visionOS it says:
Timed out waiting for a launch/connect to Preview Shell after 30.0 seconds.
