THANK YOU! Brian. You are a blessing!

Hi Brian, How we can handle with left alignment for the searchBar placeholder? Thanks!

Hey amazing video part 23. I was wondering if you can also integrate two other option? Like - people can post picture of video. - people can make a Hashtag (#). Those option will be great

Brian, I see strange warning " Unbalanced calls to begin/end appearance transitions for ... " if I go back from the UserProfile to the UserSearch... Code is the same by me and don't see it in your console ;-(

Hi Brian. There seems to be a bug in my code, every time I load up my app and go to the user profile the posts do not appear on the profile. Is this something we are going to learn to take care of in the later lessons?

Hi Brian, I noticed that if you go user from search and back ( for few times ) the screen is still alive. His reference dose not dismiss. Is it something with strong and weak? Regards, Hen

Hey, Brian. I'd like to know how to dismiss the keyboard. I know that it's very simple but I tried a lot of ways and I don't get what I'm doing wrong.

Hi Brian, I made search bar like this, navigationItem.titleView = searchBar, and didnt have many of these problems. By the way excellent video, thanks.

Great pace and explanation Brian! Interestingly enough I ran into an issue with Facebook's iOS App this morning where the keyboard wouldn't dismiss from one UI text field which led to it covering up the next date field UI scroll controller for selecting years. #evenzuckerbergshouldwatchLBTA

Hi Brian, I know this is too much to ask but do you have any recommendation any references to read, watch for programming progmatically?. I really inspired of not using the storyboard. Doing everything in coding made me easy to understand how everything works. I just want to practice and learn more. If you got recommendation please reply. Or you can make a video tutorials I dont mind paying for it because I know it will be worth it. Thanks Senpai

Hi brian, I used to write : for (key, value) in dictionaries Instead of... dictionaries.forEach( {key, value in... because I found this is easier to use... Is this exactly the same result ? Actually, I have now an issue with the first fix of this video : the "return" statement results in stopping the fetchUsers function. I suspect that the above mentioned syntax may be the cause of this issue ? Is this a matter of synchronous/asynchronous function ?

hey brian, i want to understand how the UserProfileController is being used. so basically this line let uid = userId ?? Auth.auth().currentUser?.uid ?? "" means, if i go to search controller and tap on a user, it will go to UserProfileController and call the fetchUser() function from viewDidLoad, thus it will be "userID" from the line above? and if I go directly to profile, its going to call Auth.auth().currentUser?.uid, do i understand it properly? Thanks

Hi Brian, I wonder why not just directly pass the user from UserSearchController to UserProfileController when the user clicked on a certain user? The selected user's info has been downloaded, why fetching it again? The code would be like this: - UserSearchController didSelectItemAt: userProfileController.user = user navigationController?.pushViewController(userProfileController, animated: true) - UserProfileController viewDidLoad(): if user == nil { fetchUser() } because user is just set, that's no need to download the user info from uid again right? Since it's not that clean to keep a user var and a userId var at the same time. If they go out of sync for some reason, it will create some unexpected trouble.

Hi Brian, I've started to notice that when I move from the search page to the home feed and scroll down quickly, all the photos get jumbled and the console spits out the following: Will attempt to recover by breaking constraint <NSLayoutConstraint:0x60800009c8e0 'UISV-canvas-connection' V:[UIButton:0x7f8c9b03cb70]-(0)-| (active, names: '|':UIStackView:0x7f8c9b03de30 )> Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger. The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful. 2018-09-06 21:04:12.904816-0700 InstagramFirebase[9676:8297519] [LayoutConstraints] Unable to simultaneously satisfy constraints. Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. Is this a known bug? Or have I added constraints incorrectly?

hi Brian i follow this lesson to the T and i can't not get the userProfile to load when i click on the user from the search profiler... I download the source project and still can't figure it out...

Providing Optimal solution: Hello Brian, i wanna share my own optimal solution and you could give me right feedback on it: I removed collectionView.reloadData() from fetchUsers() then , i added: self.timer?.invalidate() self.timer = Timer.scheduledTimer(timeInterval: 0.1, target: self, selector: #selector(self.reloadCollectionView), userInfo: nil, repeats: false) and inside reloadCollectionView: i typed self.collectionView.reloadData() I do all of that to minimize the call of reloadData just if i have 1000 records in collectionView ..... is that optimal solution, Brian ?! Thanks...

Brian, I keep getting an error "Permission Denied". Any fix for the Database rules in Firebase?

how to delete the users on firebase? i just deleted them from authtentication website, but I still have like repited users xD I think this is from the cache of the simulator or something?

Profile images are swapped around when using filtering, names are stable but images are not. Any solution?

Brian, why does the searchUserController UIWindow goes black while just getting the snapshot from observeSingleEvent on this line 'Database.database().reference().child("users").observeSingleEvent(of: .value, with: { (snapshot) in' when accessing the controller from homefeed embeded as serchBar on the NavBar, so I open the controller like this: func searchBarShouldBeginEditing(_ searchBar: UISearchBar) -> Bool { handleShowSearchVC() return false } @objc func handleShowSearchVC() { let s = UserSearchController(collectionViewLayout: UICollectionViewFlowLayout()) s.modalPresentationStyle = .overCurrentContext navigationController?.pushViewController(s, animated: true)

Any reason why the tab bar disappears when I click on a searched users profile?

Another issue, when I click the options button after searching a user and clicking their profile. It ask me if I want to log out of the user I searched for. Any way to go about this? Thanks!
