Doesn't look like anything we can fix in delve. This should be reported to apple, debugserver is just crashing.

had the same issue, was able to resolve it via removal and installation of xcode command line tools:

sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install

[aarzilli]

Closing, problem with xcode not delve.

I had the same issue. After running these commands I was able to use the Delve Debugger and fix my problem! Thank you!
