Xcode 6 - Syntax highlight / completion not working

Question

After one day my code loses its highlight / completion again in xCode 6.

As always, I tried to Organizer > Projects > and Delete Derived Data. Which did not work in Xcode 6, even after it finish to index everything.

I tried to uninstall and install 3 times - and its still coming back after some time.

I really can't find why Xcode loses it.

Any help will be appreciated.

Answer 1

Syntax highlighting and code completion can sometimes only work on part of the file too, and it happens during the editing or on a random basis.

I fix this by cleaning the project... not a sexy solution, but it works.
