I created custom Poster view so it can be reused in multiple collection view cells (just like TVPosterView in TVUIKit). I add it directly to cell content view with all needed constraints. The problem is when cell is focused this subview doesn't receive focus update (didUpdateFocus..) so I cannot customize it's focused / unfocused constraints etc. It's odd btw that image view inside is getting floating effect. In case if I specify cell's preferredFocusEnvironments, the collection view delegate method didSelect not called! Thanks in advance for any help!

Hello colleagues. My question is whether or not Xcode Previews source code included (or removed) starting Xcode 12.5 in: final binary of the application? SwiftPM package library artifact? I know there's "Development Assets" folder that's included for previews only. But I didn't really find information about preview source code. Thanks, Dzmitry.

Hello colleagues, I have question regarding passing data that doesn't need to change. In video suggested to use let, and it totally make sense! But I also found following issue: https://forums.raywenderlich.com/t/question-regarding-chapter-8-4/136398/2 I am wondering how to avoid rendering path optimisation to make sure it's not cached somewhere in between? Or was this something already fixed in prior SwiftUI versions? My example: struct ModelDetailsView { @ObservedObject var viewModel: ViewModel     @ViewBuilder     var body: some View {         ModelItemsSection(viewModel.$model.subitems) .onAppear(perform: {             self.viewModel.load()         })     } } struct ModelItemsSection: View {     let items: [ModelSubitem] // simple struct     var body: some View {                 PreviewItemsView(items: items, allItemsTitle: "All Items") { item in Text(item.titleDetail + item.subtitle)                 } allItemsView: { items in //3rd level screen where `let` data is passed that's destination to NavigationLink                     AllModelItemsView(items: items)                 }     } } Thanks, Dzmitry.

Can NSInputStream.read(_:maxLength:) return less bytes read even when more data available? I haven't found it in the docs Use-case: we pass maxLength = 512, but actual reading of 512 bytes will do in 2 rounds: 256 in first round + 256 in second. It's important for my use-case (encryption/decryption) not to have intermediate partial readings unless it's last "tail" part. Otherwise I might end-up encrypting different-length blocks & decryption will fail assuming different buffer length.

Starting iOS16 navigation title has default share menu. Is there any APIs to disable it? I tried following but it didn't help: navigationItem.documentProperties = .init(metadata: LPLinkMetadata.init()) navigationItem.titleMenuProvider = { _ in UIMenu.init() }

Report status of interactive widget triggered action (pending, loading, failed, completed)? I can think of continuously calling WidgetCenter.shared.reloadTimelines(ofKind:) but afraid to exceed reload budget.
