great tutorial on delegate!

there is a small bug in your challenge solution code :) in HomeController, fetchCurrentUser function you have to move self.hud.dismiss() call out of the error block :) other way it keeps spinning :) unless there is an error ofc :)

Hey again, could you provide with some fixes? :) 1. Pagination when sorted 2. Disable age sort / show users with N/A age 3. Omitting our current logged in user in fetched/displayed results 4. Save Bio. And (as i wrote a couple episodes back) multi-line bio display :)

Thanks for the very well explained delegation method :-)

Short and sweet in the delegation explanation. Just started working as an iOS developer for a week. I just went and check on the code in my assigned project and I realised that the previous developer did not implement any protocol and delegation methods. She was an experienced Objective C developer and and even with her experience in Objective C, she did not use any protocols when she moved into swift. I certainly hope to have a chance to implement some protocols in my current project.

More Fire!

Hi Brian i have a little question, i see in some projects, there some protocols have "class" word after the name of the protocol like this... protocol nameProtocol: class { func nameFunctionDelegate() } and when the instance is created, they call like this.... weak var delegate: nameProtocol? ( i dont know if is like for the retain cicle? maybe?)

one question: why is settingsController.delegate = self in the handleSettings function of the home controller? Can this be in the viewDidLoad section?

I noticed a bug at this point, not sure if it is going to be fixed in later lectures. If you keep hitting refresh button, new cards will keep being appended to the array and the same cards will be added to the card stack.

I can't download the project

Hi~Brian i have error, i don't kown how to fix. Error message: Object is destroying itself properly, no retain cycles or any other memory related issues. Memory being reclaimed properly

Hey Brian, I'm wondering what you think of my solution to your challenge at the end of this video. I used a protocol with a default implementation of the function. protocol FetchCurrentUser { func fetchCurrentUser(completion: @escaping (User) -> ()) } extension FetchCurrentUser { func fetchCurrentUser(completion: @escaping (User) -> ()) { guard let uid = Auth.auth().currentUser?.uid else { return } Firestore.firestore().collection("users").document(uid).getDocument { (snapshot, error) in if let error = error { print(error) return } guard let dictionary = snapshot?.data() else { return } let user = User(dictionary: dictionary) completion(user) } } } Calling it in HomeController would look like this: fetchCurrentUser { user in self.user = user self.fetchUsersFromFirestore() } Calling it in SettingsController would look like this: fetchCurrentUser { user in self.user = user self.loadUserPhotos() self.tableView.reloadData() }

Hey Brian, I'm looking to refresh the stack while on the main screen without having a user logged in. Any ideas?
