SourceKitService eating all CPU on Xcode 8.3.2

Question

I'm ok Xcode 8.3.2 and SourceKitService is using all my CPU. I read a lot of questions here on stackoverflow, but I could't find a real solution.

What I tried:

• Clean project data: cmd+shift+alt+K
• Delete derivedData folder
• reboot Xcode
• redownload the project code from git

Nothing worked. I understood the issue is probably related to some code, but how can I spot where is the issue? My project is quite big...

Currently Xcode is unusable...

Thanks for your help

This is not really a "fix" because it will also be detrimental to people who rely on having live issues shown to them. But if you go to Preferences->General and switch off "Show live issues" then xcode runs like a bunny on a cool spring day. I prefer that over having to force quit SourceKit service every now and then.
