Xcode playgrounds: project is stuck in Failed to launch process - report a bug

Originator:markd
Number:rdar://30334060 Date Originated:2/2/2017
Status:Open Resolved:
Product:Developer Tools Product Version:Version 8.3 beta (8W109m)
Classification:Serious Bug Reproducible:Didn't Try
 
Summary:
Trying to use playgrounds. Radar number seven for the day. >:-(

See attached screenshot - "Failed to launch process. Error returned in reply: Connection invalid" with a report-a-bug button.  That's why I'm here.

Attached is a movie showing what I'm seeing. The error happens when I open the playground.

The console was full of xcode errors.  See other attached screenshot for a sample.

Things are happier after relaunching xcode.

It'd be nice if there was a way to tell Xcode to gather a snapshot of interesting stuff when it vomits itself (c.f. rdar://29884107 ), which for me happens quite often.  (c.f. rdar://22524679)

The playground in question is attached.
