Hey Brian, I think it would be nice if you fetch the data in the background thread and later reload the collection view once you receive all the appResults. That way we can reduce the load on the main thread.

Hi brian just wanted to ask you that, what is the difference between using SearchResultUpdate and SearchBarDelegate

passing the searchTerm directly into URL string crashes the app if search term contains spaces. We need to encode it before creating the URL. I used searchTerm.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed) to solve this issue. Is It the right way of solving this issue?

Hi Brian, if we look at the original App Store app search functionality, when we start to type, a tableview shows up with the predictions. I'm thinking how could we achieve that? It is like we have two tableviews in the view controller, one for app cell, another one for prediction. When starts to type, predictionTableView.isHidden = false, kinda like that? Thanks

This is my favorite video so far! Even though all content is great! I'm really happy I purchased this, will definitely apply these skills in my personal app! Thank you, Brian!

Hi Brian, You have a bug inside your fetchApps method at Service.swift file. You should addingPercentEncoding to your searchTerm before you add this string to the URL. Now when user type for example space character like Uber Eats inside the search bar your method throws an error because of unencoded character and API call fails.

You didn't say how to code the get button to pull data from JSON

Also when searching a two or more word phrase you get an error ie: "facebook messenger" how do I correct this?

Love the video’s learn so much each time thanks heaps

Just wanted to say thank you for this! Much of it I am well aware of but it helps to see how many other ways there are to do the same things! For the text on the empty state, you can also try creating an extension on the collectionView class to set its backgroundView: extension UICollectionView { func setupEmptyState(with message: String){ let enterSearchTermLabel: UILabel = { let label = UILabel() label.text = message label.textAlignment = .center label.font = UIFont.boldSystemFont(ofSize: 20) return label }() self.backgroundView = enterSearchTermLabel } func restore() { self.backgroundView = nil } } Calling that setEmptyState method if appResults.isEmpty and returning 0. Else set the backgroundView back to nil by calling the restore method and returning appResults.count I use this to include buttons etc as well since it takes a view and not just a label...found it somewhere through a stackoverflow thread some while back :) thanks again Brian!

Is a excellent course, i dont speak english and y try make the exercise and is a practice good xd

Brian, is there a difference if I use: DispatchQueue.main.asyncAfter(deadline: .now() + 0.5) { self.collectionView.reloadData() } for delay on the search instead of the timer you configured?

Great lesson... I have one Contextual closure type error... can you assist? func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) { print(searchText) timer?.invalidate() timer = Timer.scheduledTimer(withTimeInterval: 0.5, repeats: false, block: { (_) in Service.shared.fetchApps(searchTerm: searchText) { (res, err) in self.appResults = res DispatchQueue.main.async { self.collectionView.reloadData() } } }) }

Hi Brian, I was wondering if you'd be able to help me with a question. One thing I'm struggling with is how you know what the names of the properties are that are part of certain classes in UIKit. For example, you used the searchController property of the UISearchController class and just assigned the UISearchController object you created to it. I didn't know it was that simple. How did you become aware of the various properties that each UI element has as part of it's class? Is it through the documentation?

how to do something like this with firebase

i mean Search Bar Controller

not ideal but i wrote a function to fix the space issue in the search term func urlifyWithPercent(string: String) -> String { let str = string.components(separatedBy: " ") let arr = str.filter( { $0 != "" }) let newString = arr.joined(separator: "%20") return newString } to use:- let urlString = "https://itunes.apple.com/search?term=\(urlifyWithPercent(string: searchTerm))&entity=software"

Hi, Just an update for anyone following this project from iOS 12.0, searchController.dimsBackgroundDuringPresentation = false // deprecated from iOS 12.0 instead use, searchController.obscuresBackgroundDuringPresentation = false Thanks.

When i click on search bar app is stopping/freezing donno what happening. I am using swift 5 and Xcode 11.1

Hey Brain cool throttling technique! Was wondering about the technique of resigningFirstResponder() vs search throttling? // UISearchBarDelegate func searchBarSearchButtonClicked(_ searchBar: UISearchBar){ // pass text here since search button clicked? searchBar.resignFirstResponder() }

hey brain hope you are doing well, thank you for these work I have a problem when I run the project in iPhone 6 when collection view is empty UISearchController didn't appear and I can't search for data but when I run in iPhone x max is work fine can you help me to fix this ... thanks, again.

Hi Brian, I am sorry to bother you with this but I found a bug that I cannot fix. When a user swipes instead of clicking one key at a time on the keyboard and makes use of the swipe text keyboard feature the collection view breaks and no longer scrolls. I have tried to google search the issue but because it seems to be a rare issue I just keep finding solutions on how to swipe dismiss the keyboard which isn't the issue.
