I am using Xcode Version 6.1 (6A1052d) , it works well, except that the only problem is completely completed and the meaning of the code is broken for swift projects.
I can fix this by deleting the derived data and the ~/Library/Caches/com.apple.dt.Xcode folder described here , or changing the deployment target project from 8.1 to 8.0 .
However, the first solution is delayed only by 1 or 2 days, due to the fact that it does not work again, I do not want to delete folders as often or constantly change target versions of iOS. Please help me.
