When I use ```self.messages = objects; [self.tableView reloadData]; NSLog (@"Retrieved %d messages", [self.messages count]);
,the console shows 0 messages.

9,561 PointsI had the same issue. Looking at my parse tables, I realized that something was different than in the video.
[query whereKey:@"recipientIds" equalTo:[[PFUser currentUser] objectId]];
in parse the column for recipients is actually called recipientsIds. So change that line of code to this
[query whereKey:@"recipientsIds" equalTo:[[PFUser currentUser] objectId]];

[query whereKey:@"recipientIds" equalTo:[[PFUser currentUser] objectId]];
[query orderByDescending:@"createdAt"];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if(error){
NSLog(@"Error %@ %@", error, [error userInfo]);
} else{
//we found messages
self.messages = objects;
[self.tableView reloadData];
NSLog (@"Retrieved %d messages", [self.messages count]);
}
}];

42,016 Pointsok looking at this line here:
PFQuery *query = [PFQuery queryWithClassName:@"Messages"];
double check your parse backend using the parse data viewer and make sure you named your class "Messages". you may have called it "Message". if you did name it Message thats whats causing the issue and you would need to change that in your code to
PFQuery *query = [PFQuery queryWithClassName:@"Message"];
