Since Xcode 7 (currently running Version 7.3 (7D175)), the syntax highlighting engine of Xcode (which also seems to include the auto-completion) randomly crashes, meaning the text color of the code gets all white, no more warnings or build errors will be shown in the current file, breakpoints get ignored and auto-completion stops working, rendering the IDE useless for the currently opened file.
This happens sometimes while I am writing code, sometimes just while looking at code without touching trackpad or keyboard. The only way to resolve the issue is to restart Xcode.
I have tried re-installing Xcode and OS X (running 10.11.3 (15D21)), which did not resolve the issue.
In my office, I am not the only one experiencing this issue, so it seems not to be connected to my Mac / installation. Is anyone else also experiencing this and is there a fix?
Thanks
