Best episode so far! Thanks

Often, you seem to do the Search tab first. Any special reason?

Hey Brian, Is there a difference between .layer.masksToBounds = true VS clipsToBounds = true? I know that there are a lot of explanations out there (https://stackoverflow.com/questions/39466001/maskstobounds-vs-clipstobounds) but have you ever had to choose which one to use? Or you just use the clipsToBounds for every case?

Ho Brian, When we set the cell properties ,can we put those in the didSet function in the cell class instead in the cellForItemAt function?

Hey Brian, question about your refactored code from the VC to the View. You are calling one of the functions in the SDWebImage library but you don't need to import SDWebImage in SearchResultCell.swift. I thought that you couldn't use a library in a swift file without importing it first. Do you mind clearing this up for me?

Hey Brian, I wanted to reduce the amount of condition logic so instead of checking if the returned image count was greater than 1 or 2, I used a for loop let ss = [cell.ssOne, cell.ssTwo, cell.ssThree] for (index, element) in data.screenshotUrls.enumerated() { guard index < ss.count else { break } ss[index].sd_setImage(with: URL(string: element)) } Is this approach OK? I added a guard statement to ensure if the API returned 4 images I would not get a crash from only having 3 screen shots in my ss array.

Hello Brian, First of all nice video and I enjoy it pretty much so far. I have one question tho since i encountered a bug. I will describe it now. I have done this a bit differently to practice even more, instead of loading 3 screen shots, I made a whole collection view to load all the screenshots that are fetched from the api. Everything works find but there is a really weird bug. When you scroll down using the api in this video, only on 23rd row (PolaUS app) the images on screenshot are changing and are displayed with wrong content in them when the collection view is dequeuing them. Every other app from the api is just fine. Does something special happen on 23rd row or what am I missing here?

Hey Brian, I'm working on a scrolling Reusable headerView, and there is a collectionView nested inside the header to have the ability to load the total amount of images for the post (horizontal scrolling). The data is initially passed in from the HomeViewController which uses the didSelectHandler we wrote in the video, which is then passed into the appId on the DetailViewController. However, since I need to load the images in via the ItemHeader because of the nested collectionView cell (to my knowledge), the data is nil when I try and sd_setImage that way. Is there a way to get the data from DetailViewController into the Header Cells? I tried to call an object of ItemHeader in the didSelectHandler on the HomeView but that didn't work. class ItemHeader: UICollectionReusableView, UICollectionViewDelegateFlowLayout, UICollectionViewDataSource { let cellId = "cellId" var app: Result? func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int { return 4 } func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell { let cell = collectionView.dequeueReusableCell(withReuseIdentifier: cellId, for: indexPath) as! PhotoCell cell.imageView.sd_setImage(with: URL(string: app?.artworkUrl100 ?? "")) // This RESULTS in NIL return cell } func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumLineSpacingForSectionAt section: Int) -> CGFloat { return 0 } func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize { return CGSize(width: frame.width, height: frame.height) } let collectionView: UICollectionView = { let layout = UICollectionViewFlowLayout() layout.scrollDirection = .horizontal let cv = UICollectionView(frame: .zero, collectionViewLayout: layout) cv.backgroundColor = UIColor.lightGray cv.isPagingEnabled = true cv.layer.masksToBounds = true cv.isScrollEnabled = true return cv }() ... } class PhotoCell: UICollectionViewCell { override init(frame: CGRect) { super.init(frame: frame) layoutViews() } required init?(coder aDecoder: NSCoder) { fatalError("init(coder:) has not been implemented") } let imageView: UIImageView = { let view = UIImageView() view.contentMode = .scaleAspectFill return view }() private func layoutViews() { addSubview(imageView) imageView.fillSuperview() } }

Swift package manager is super cool! Love it. So much faster and easier to install dependencies!

Hey Brian, I don't really understand why the computed property "var appResult : Result! { didSet{ } }" you need the bang 'Result!' and if you don't add the bang, the error "Property self.appResult not initialized at super.init call" pops up. How does '!' initialize values, it's a Decodable? Stackoverflow makes no sense. Thank you for your time! https://stackoverflow.com/questions/24021093/error-in-swift-class-property-not-initialized-at-super-init-call “Swift’s compiler performs four helpful safety-checks to make sure that two-phase initialization is completed without error:” Safety check 1 “A designated initializer must ensure that all of the “properties introduced by its class are initialized before it delegates up to a superclass initializer.”

Hello Brian, I use the image Cache extension from your video back in 2016. <https://www.youtube.com/watch?v=GX4mcOOUrWQ> @24:31 is there a difference in using the cocoapod and native code?
