I'm having this error and it came from nowhere. The compiler was working well until last week. My compiler is taking a lot of time to compile the code and almost all of the times are returning me this error. I've been having a lot of trouble after the iOS 11 was release. Do you know what it means?

enter image description here

I have Xcode9 and I'm asking if it's a problem with the new version or something like else. Also I don't know how to fix this, since I was searching for this answer this last 5 days with no success.

    Did you merge storyboards with other commits? – Sulthan Nov 14 '17 at 19:51
  • Nope. I'm just commit my code twice in the week. After the iOS 11 update I've been having lots of warnings, mainly about constraints. After this last update I got this error and it's taking an eternity to compile the code. =/ I really don't know what to do now. I've been searching for this errors for days and without success. – Khromos Nov 14 '17 at 19:54

After cleaning the project and derived data, try to uncheck the following option:

Xcode->Preferences->General->Issues->"Show live issues"
