XCode can''t find header of 3rd party library

Question

I'm trying to add the Ensembles 2 framework to my iOS project (switching from the open source Ensembles 1, v2 is not open source so I don't have access to the code or cocoa pod anymore).

I think I followed the install instructions to the point:

1. Dragged in the framework (and the .bundle)
2. Made sure targets and "copy items" are selected
3. Made sure -ObjC is set

XCode copies the framework to $(PROJECT_DIR) which is also set in Framework Search Paths (among other dirs). It seems to be unable to find <Ensembles/Ensembles.h> though, no matter what I try. I searched similar questions on SO and elsewhere and tried various combinations of Framework Search Path settings and Header Search Path settings but have had no success so far. Specifically I tried

• Adding and removing quotes from existing Framework Search Path settings
• Playing with the recursive setting
• Creating a Frameworks subdirectory and adding the framework there. Then add "$(SRCROOT)/Frameworks to Framework Search Paths and Header Search Paths (both recursive and non-recursive)
• Adding "$(SRCROOT)/Frameworks/Ensembles/Headers" to Header Search Paths
• Deleting, cleaning, and re-adding the framework multiple times

This is getting frustrating. Any other ideas? I'm using XCode 7.2.1 btw.

Answer 1

Ok, this seems to have been an XCode issue, probably some cached intermediate files or something. To resolve I

1. Went to File -> Workspace Settings... to find the build directory
2. Quit XCode
3. Deleted everything in the build directory
4. Restarted XCode, recompiled, et voila...
