My CheckMarks aren't showing up

I think it would be useful if you post the didSelectRowAtIndexPath: method

Do you mean that the checkmarks aren't showing on the main friends list (not the 'edit friends' list)? That's normal; making the checkmarks appear there will actually be covered later in the course when you learn about the ViewController lifecycle.

I think it's a problem with this video that this isn't actually addressed here -- it confused me too at the time.

apologies for the slight difference in code as i stupidly went onto the next video and didn't test! schoolboy error i know hope this helps ! thanks again

If you add friends in the 'edit friends' screen, then stop the app in Xcode and run it again, do the friends show up then? If so, this is related to the ViewController lifecycle issue I mentioned above and will be resolved later.

It seems that friendsRelation is not working fine. Have you already check if...

PFRelation *friendsRelation = [self.currenUser relationForKey:@"friendsRelation"];

...is returning what is expected? If you add a user it appears in parse.com?

Just and Update for you both I've found that it wasn't running my prepare for segue code

'''-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {

if([segue.identifier isEqualToString:@"showEditFriends"]) {
    EditFriendsViewController *viewController = (EditFriendsViewController *)segue.destinationViewController;
    viewController.friends = [NSMutableArray arrayWithArray:self.friends];
}

} '''

because in the link between the view controllers in the storyboard i hadn't put my 'identifier' in now i have done this and copied the equal to string text to avoid typos it throws up and error and is crashing on the prepare for segue with and error of SIGBART

'''

int main(int argc, char * argv[]) { @autoreleasepool { return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class])); } } '''

in the log its terminating on uncaught expectation of type NSExpectation

hope this helps !
