The SwiftUI Navigation structures work in ways that are not intuitive to me. For example, I am trying to display a set of data that represents rankings contained in a balloting system that I have created. The ballots all have candidates that are ranked from highest preference to lowest. Normally, I try to work backwards in SwiftUI, so I built the ballot editor to take a binding to the ballot itself: struct BallotEditor: View { @Binding var ballot: Election.Ballot var maxRank: Int var body: some View { VStack { ForEach($ballot.rankings) { $ranking in CandidateRankingPicker(maxRanking: maxRank, ranking: $ranking) } } } } This is embedded into a view with a list of ballots: struct BallotsView: View { @Binding var document: ElectionDocument var body: some View { List($document.ballots) { $ballot in NavigationLink { BallotEditor(ballot: $ballot, maxRank: document.election.candidates.count) .padding() } label: { BallotListElementView(ballot: ballot) } } } } This portion works in the editor. When the ballot is selected, the editor populates the selected candidate choices, and the editing works. However, when I attempt to insert BallotsView into a TabView, the NavigationLink stops working as expected. I didn't think NavigationLink was the proper way to do this, but it had been working. TabView { Tab("Ballots", systemImage: "menucard") { BallotsView(document: $document) } Tab { CandidateView() } label: { Text("Candidates") } .tabViewStyle(.sidebarAdaptable) } This is my third iteration. I have tried using a List with selection, but in that case, I am unable to pass the binding to the detail view. I just don't understand how this works, and I am preparing a version in Cocoa so that I don't have to deal with it anymore.

I'm currently working on transitioning to StoreKit 2. In order to see if my users are legacy users who purchased the app before I implemented an in-app purchase, I am trying to use the original purchase date for the app. Unfortunately, it's returning 0 seconds since 1970. func updateOriginalPurchaseStatus() async throws { let transaction = try await checkVerified(AppTransaction.shared) self.originalPurchaseVersion = transaction.originalAppVersion self.originalPurchaseDate = transaction.originalPurchaseDate } This is from the transaction: [3] = { key = "originalPurchaseDate" value = number (number = 0) } Currently trying to figure out when I actually purchased the app, but it might be as early as 2012. And I likely used a download code.
