Description Todd Berman 2014-03-09 20:54:57 UTC
Although it says it returns `id`, the docs are clear that it will return a UICollectionResuableView:

https://developer.apple.com/library/ios/documentation/uikit/reference/UICollectionView_class/Reference/Reference.html#//apple_ref/occ/instm/UICollectionView/dequeueReusableSupplementaryViewOfKind:withReuseIdentifier:forIndexPath: (see specifically the 'Return Value' section)

I have checked this issue on below environments:

All Mac
XS 4.2.3 (Build 60)

I noticed that UICollectionViewDataSource.GetViewForSupplementaryElement method's return type is UICollectionResuableView, Refer screen shot: http://screencast.com/t/nAoIy80Kmb

Let me know if I am missing anything to check this issue.
Comment 2 Todd Berman 2014-03-11 11:09:24 UTC
Sorry, it was mistitled, the doc link is correct though, It is with:

DequeueReusableSupplementaryView, not GetViewForSupplementaryElement
Comment 3 Sadik Ali 2014-03-11 11:24:56 UTC
I checked this issue as per comment2 and noticed that method
UICollectionViewDataSource. DequeueReusableSupplementaryView missing, 

Refer screen shot: http://screencast.com/t/m5SUdMBR
Comment 4 Todd Berman 2014-03-11 11:26:09 UTC
Yeah, it is in the UICollectionViewDelegate, not the DataSource, sorry about that. It is also in that combined class, UICollectionViewSource.
Comment 5 Todd Berman 2014-03-11 11:27:13 UTC
Er, Sorry, UICollectionView.

It is early here!
