I've read a lot of posts about this type of error. But I use version 1.12, and the issues talked about earlier versions of the Parse SDK.
I find it sort of ridiculous that XCode throws these errors, when using a professionally produced set of libraries (Parse's Facebook interaction libraries).
So I would like to give a set of steps to reproduce the bug:
Start a new blank project in XCode.
Download the Parse SDK (I don't use Pods). It'll appear in the downloads folder. Now drag and drop it, select "Copy items" so you copy that over into Xcode.
Now in any .h or .m file you want, write:
#import <ParseFacebookUtilsV4/PFFacebookUtils.h>
Now you get:
"Could not build module 'ParseFacebookUtilsV4'"
You also get:
'FBSDKCoreKit/FBSDKAccessToken.h' file not found
What gives?
To be honest I haven't had the time to hack at the second error. I've exclusively hit my head against the wall over the first one.
