For iOS 14, I think you have to subclass UICollectionViewListCell and override updateConfiguration(using state: UICellConfigurationState). It should work for iOS 15 also. let cellConfiguration = UICollectionView.CellRegistration<MyCell, String>....     override func updateConfiguration(using state: UICellConfigurationState) {         super.updateConfiguration(using: state)         guard var cConfig = self.contentConfiguration?.updated(for: state) as? UIListContentConfiguration else { return }         cConfig.textProperties.colorTransformer = UIConfigurationColorTransformer { color in             state.isSelected || state.isHighlighted ? .white : .black         }         cConfig.secondaryTextProperties.colorTransformer = UIConfigurationColorTransformer { color in             state.isSelected || state.isHighlighted ? .white : .black         }         self.contentConfiguration = cConfig         guard var bConfig = self.backgroundConfiguration?.updated(for: state) else { return }         bConfig.backgroundColorTransformer = UIConfigurationColorTransformer { color in             state.isSelected || state.isHighlighted ? .systemPink : .systemGray5         }         self.backgroundConfiguration = bConfig     } }

What do you mean by moving layers around? Can you give an example?

In viewWillAppear, you are trying to trying to scroll to the first item? Does your collectionView have any data at this point?

I think this works. Try on simulator. Preview gives unpredictable results. import SwiftUI struct Amount {     var value: Decimal     var currency: CurrencyCode } struct ContentView: View {     @State var amount = Amount(value: Decimal(), currency: .GBP)     var body: some View {         CurrencyAmount(title: "Some label", amount: $amount)     } } struct ContentView_Previews: PreviewProvider {     static var previews: some View {         ContentView(amount: Amount(value: Decimal(), currency: .GBP))     } } struct CurrencyAmount: View {     let title: String     let prompt: String = ""     @Binding var amount: Amount     @State var currency: CurrencyCode = .GBP     var body: some View {         HStack {             Spacer(minLength: 80)             TextField(title, value: $amount.value, format: .currency(code: amount.currency.rawValue), prompt: Text(prompt))             CurrencyPicker(selected: $currency)             Spacer(minLength: 80)         }         .onChange(of: currency) { newValue in             amount.currency =  newValue         }     } } struct CurrencyPicker: View {     @Binding var selected: CurrencyCode     let label = "Currency"     var body: some View {         Picker(label, selection: $selected) {             ForEach(CurrencyCode.allCases) {                 Text($0.rawValue)                     .tag($0)             }         }     } } enum CurrencyCode: String, CaseIterable, Identifiable {     var id: String { self.rawValue }     case AUD, CAD, EUR, GBP, NZD, USD }

Nope

class ViewController: UIViewController {     @IBOutlet weak var navigationBar: UINavigationBar!     override func viewDidLoad() {         super.viewDidLoad()         // Do any additional setup after loading the view.         navigationBar.delegate = self     } } extension ViewController: UINavigationBarDelegate {     func position(for bar: UIBarPositioning) -> UIBarPosition {         return .topAttached     } }

All the code you want to execute after refreshResources should be inside the Task block.

You can set accentColor on the NavigationStack

Did you put the breakpoint on line 42? The code execution is stopping on line 42 because you or someone has set a breakpoint on that line. Just tap on the blue breakpoint indicator on line 42 and it should disable it or you can right click the indicator and delete the breakpoint.

Here is a screenshot

Have you tried using UIBarButtonItem.appearance(whenContainedInInstancesOf: [UINavigationBar.self])

If you want to keep the itemSize same across devices you should consider calculating the interitemspacing based on the collection view content width. If you want to keep the interitemspacing same then calculate the itemSize based on the collection view content width. This is assuming you always want the same number of items on each row. Alternately consider using Compositional Layout which provides more flexibility in configuring collection view layouts. Compositional Layout

You should make aa a State var aa = 0 in S1 and make it a @Binding var aa: Int in both S2 & S3.
