Odd behavior of PFQuery

Question

I am trying to find all posts by the current user. When I add the line [query whereKey:@"user" equalTo:[PFUser user]]; the query does not even get executed, since "retrieving posts?" never prints to the console. When I comment out [query whereKey:@"user" equalTo:[PFUser user]]; it works just fine. What am I doing wrong?

    PFQuery *query = [PFQuery queryWithClassName:@"Post"];

    [query orderByDescending:@"createdAt"];
    [query includeKey:@"filter"];

    [query whereKey:@"user" equalTo:[PFUser user]];

    [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
        NSLog(@"retrieving posts?");
         ...
    }];

I don't know the obj-c but the correct implementation in Swift would be:

query.whereKey("user", equalTo: PFUser.currentUser())
