We have been supporting a small company's iPad app for about a year now as an Ad Hoc distribution. This was a quick way for us to launch this internal app on a handful of devices. The issue is that ad hoc builds expire after 90 days, meaning someone always needs to generate a new build for folks to continue using the app. The app needs to be inside of the company network in order to access the backend web services, so it wouldn't be "review-able" from an App Store perspective. I know there are several ways to distribute internal apps - some of which were recently introduced. My question is, which method is the best way to go? Enterprise account? App Store (but only for internal folks)? What's the best way to clearly understand the best way amongst the options?

I am getting an error when trying to fetch objects in SwiftUi in a form sheet modal in iOS 13.Here's the error:[SwiftUI] Context in environment is not connected to a persistent store coordinator: <NSManagedObjectContext: 0x600003218620>I am able to run a fetchRequest from a list view, but not in the modal.Has anyone else seen this issue?I set the Environment context in the SceneDelegate:if let windowScene = scene as? UIWindowScene { let window = UIWindow(windowScene: windowScene) let managedObjectContext = (UIApplication.shared.delegate as! AppDelegate).persistentContainer.viewContext //managedObjectContext.mergePolicy = NSMergeByPropertyStoreTrumpMergePolicy window.rootViewController = UIHostingController(rootView: ContentView().environmentObject(sampleViewModel).environmenbject(customerViewModel).environment(\.managedObjectContext, managedObjectContext)) self.window = window window.makeKeyAndVisible()In the ContentView:import SwiftUI struct ContentView: View { @State var isPresented = false var body: some View { NavigationView { VStack { // Search bar, filter, and divider SampleListView() } .sheet(isPresented: $isPresented) { NewSampleView() } .navigationBarTitle("Samples") AddSampleButton(isNewSamplePresented: $isPresented) } } }Able to see items in the SampleListView:struct SampleListView: View { @EnvironmentObject var viewModel: SampleListViewModel @FetchRequest(fetchRequest: Sample.allSamplesFetchRequest()) var samples: FetchedResults var body: some View { List(self.samples) { sample in VStack(alignment: HorizontalAlignment.leading) { NavigationLink(destination: SampleView(activeSampleModel: ActiveSampleViewModel(sample: sample))) { Spacer() Text(sample.trackingNumber ?? "") Spacer() Text(sample.sampleId ?? "") Spacer() } } } } }But I get the error when presenting the NewSampleView (I've tried using a fetchRequest defined in the view as well as one defined in the NSManagedObject subclass but the fetch is always failing with the above error) :import SwiftUI import CoreData struct NewSampleView : View { @State var customerId = "" @State var sampleDate = Date(timeIntervalSinceNow: 0) @State var receiptDate = Date(timeIntervalSinceNow: 0) @State var customerServiceSampleNumber = "" @State var notes = "" @Environment(\.managedObjectContext) var managedObjectContext @FetchRequest(fetchRequest: fetchRequest(), animation: nil) var customers: FetchedResults var body: some View { List(self.customers) { customer in VStack(alignment: HorizontalAlignment.leading) { Spacer() Text(customer.customerId ?? "") Spacer() } } } static func fetchRequest() -> NSFetchRequest { let request: NSFetchRequest = Customer.fetchRequest() as! NSFetchRequest request.sortDescriptors = [NSSortDescriptor(key: "name", ascending: true)] return request }
