Every time I try to launch Xcode Previews on device, I get this error:
"RemoteHumanReadableError: The operation couldn’t be completed. (BSServiceConnectionErrorDomain error 3.)

BSServiceConnectionErrorDomain (3):
==BSErrorCodeDescription: OperationFailed"
Does anyone know what could be causing this error? I yet to use on-device Xcode Previews because it keeps crashing.

Howdy,

Sorry to hear you are having issues. Could you double check what iOS build is running on your device?

I am replicating the Swift UI tutorial and encounter the reported issue running on XCode 12.3 .
The preview breaks when the variable which hold the .json is passed to preview.

The solution was to delete my custom .json file and rename *theirs "landmarkData.json"

If anyone is still experiencing this issue we will need the diagnostics Xcode Previews generates in order to make sure we understand the error the previews system is encountering.

When you get an error in Xcode Previews, an error banner appears in the canvas
Click the "Diagnostics" button in that banner
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)

and upload that to a new feedback.
