I just update to Xcode 6 and now in the FacebookSDK.framework > Headers > FBOpenGraph.h I have 2 warnings one that reads

'atomic' attribute on property 'description' does not match the property inherited from NSObject

And the second reads 

'copy' attribute on property 'description' does not match the property inherited from NSObject

Both these warnings on line line 69 in the code I have added a comment just above that line This is the .h file I am taking about

I had the same problem.

So I changed description to copy

And then description to atomic

And no more warnings, you could also try uploading a new Facebook.SDK as they might have changed it

No problem

Updating Facebook SDK to newest version should resolve your issues, you are probably using old version whic is not ready for iOS 8 SDK

Download here - https://developers.facebook.com/docs/ios

After you install new FB SDK, you should just Clean project and Build again without errors

I fixed the warning by just commenting out the property.

These warnings are coming from FBOpenGraphObject.h. If you check the line producing them you will see that the description attribute is anyway depreciated and that objectDescription shall be used.

@property (retain, nonatomic) id      Description __attribute__ ((deprecated("use objectDescription instead")));

I would suggest you just follow FB recommendation. Most likely you are not using this property anyway. In my case, Since I was not using it, commenting out the property removed the warnings.

Hope it helps.

Go to ~/Library/Developer/Xcode and remove the whole contents of Xcode directory (Please be aware that there is some Xcode Archives there etc. so make sure you won't loose anything you need).

  • are you talking about in finder? – iqueqiorio Sep 19 '14 at 15:18
  • Yes, but the ~/Library folder is hidden by default. – czaku Sep 19 '14 at 15:24
  • when I'm in my finder and go macintosh HD I see library and developer nut then no Xcode – iqueqiorio Sep 19 '14 at 15:32
  • It is inside your user directory, so the path is /Users//Library - it is NOT the /Library directory at the top of your disk structure. – czaku Sep 19 '14 at 15:46
  • should I also remove the hidden files in there? Theres files called developer portal and folders called UserData should that all go? Ive added a screen shot of the folder – iqueqiorio Sep 19 '14 at 19:15
  • I removed everything, but you will loose Xcode settings and archives. But that fixed the same issue for me. – czaku Sep 19 '14 at 19:50

#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wproperty-attribute-mismatch" 
@property (retain,  atomic) id description __attribute__ ((deprecated("use objectDescription instead")));
#pragma clang diagnostic pop
