Xcode 6.1.1 writes too much data to disk Recently I noticed that Xcode writes too much data to the disc. Within just 40 hours it wrote more than 13GB to the disk. 



I restarted Xcode to see what actions cause this insane data transfer. I noticed that typing just one character makes Xcode write 40-50 MB of data onto the disk. As I have an SSD this makes me very "uncomfortable" using Xcode. 

How can I find out where the data is written and why it is written?
My guess is that you have a normal Xcode installation and you can confirm this with Instruments or fs_usage

You'll want to let it finish downloading any documentation and close project windows that you don't work on to focus on the background file IO.

sudo fs_usage -w Xcode  | grep -v Terminal
