Blocks/Autocompletion

[HHuckebein]

Dear all,

the following code block is never autocompleted by Xcode if I type
canDeleteManagedObject!?
What's wrong with it?

Xcode only shows
V BOOL (^)(NSManagedObject *) canDeleteManagedObject and completes
to canDeleteManagedObject.

BOOL (^canDeleteManagedObject)(NSManagedObject *) = ^ BOOL (NSManagedObject *object) {
    ///////////////////////////////////////////////////////////////////////////////////
    // check if all Values are nil which aren't of attribute type NSStringAttributeType
     ///////////////////////////////////////////////////////////////////////////////////
    __block int count = 0;
    
    BOOL canDelete = NO;
    [[object.entity attributesByName] enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {
        if (((NSAttributeDescription *)obj).attributeType != NSStringAttributeType) {
            count++;
            if ([object valueForKey:key] == nil ) {
                count--;
            };
        }
    }];
    
    if (count == 0) canDelete = YES;
    return canDelete;
};
