iOS Assertion Failure in UICollectionView

Question

Answer 1

Make sure that if you use the registerNib: method:

UINib *nibH = [UINib nibWithNibName:HEADER_ID bundle:nil];
[collectionView registerNib:nibH
 forSupplementaryViewOfKind:UICollectionElementKindSectionHeader 
        withReuseIdentifier:HEADER_ID];

that ALSO in the nib file, when you select the top-level collection reusable view, use the attributes inspector, and make sure the Identifier is set to the same value you are passing in to the withReuseIdentifier: parameter.
