"Connection interrupted" and "restoring service" are displayed when trying to rename class

[Visput]

I tried to rename class. As result I got such screen (see screenshot).
When I click preview system error is displayed:

Exception communicating with daemon: NSDistantObject (0x7fd9d9825dc0) is invalid (no connection)

Plugin was installed by Alcatraz Package Manager.

Looks like a SourceKit crash. What are the chances of sending the source for UICollectionViewController+Deselect.swift to injectionforxcode @ johnholdsworth.com though it could be any of your sources causing the crash TBH. The remainder of the errors seem to be "snowballing”. Xcode 7.2 right?

Just sent you email with source file UICollectionViewController+Deselect.swift
Here is screenshot of the bottom part of screen:

I’ve rewritten the plugin to not use SourceKit so this may be resolved. Do you want to give it a try with the new version?

I just got this error and now it says this:

Exception communicating with daemon: connection went invalid while waiting for a reply because a mach port died
