Xcode 5 code completion not working in .h file

Question

In my project the code completion is not working in the .h file. Any suggestions ?

EDIT:

It shows up for direct imports but not for nested imports. Even for normal imports it shows only a list of names without the symbol to the left.

Can we see the .h file as it is? This can often happen when there is a small issue somewhere in the file confusing XCode so seeing the code would allow us SO-ers to give a better answer – Guglielma

Its applicable for all .h files. Unfortunately i cant share the source. I edited my question above since it happens only in that particular case. – Cinerama

If it's all your files any chance the prefix file is invalid? – Needleful

The project builds fine. Is there anything specific i should look out for ? – Cinerama
