Answer 1

enter image description here

I got this issue when my Xcode was 9.2 . First I deleted xcworkspace file ,cleaned and built according to the others' answer.But it did not work. Then I updated Xcode to 9.3 It also did not work. I checked my code and found that the recently written code made Xcode Indexing forever:

TimeInterval(3600*24*(-randomDay))

Then I amended it:

TimeInterval(-3600*24*randomDay)

It worked. I find that many situations can cause Xcode to work abnormally.So I think the correct solution is that think about what you've done for your project recently
