Out of convenience, I constantly diff revisions and make commits within Xcode to Git. However, as of Xcode 10.1/10.2 I’ve been loosing Git functionality at random times. The message displayed when performing operations is:
Couldn’t communicate with a helper application.
Try your operation again. If that fails, quit and relaunch the application and try again.
At that point, I exit and restart Xcode and it works again until the next random fail. Does this happen with others out there?
