Mocker Crash

[gstrobl17]

Mocker uses SourceKitten to try to render the code for the mock styled. SourceKitten; however, it depends on SouceKit to work. If SourceKitten can't find SouceKit it throws a fatal error: here.

To fix this issue, you need to make sure that the Xcode command line tools are configured "properly":

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
