Embed without code sign if it is an AppName.workspace made up of an AppName.project & Alamofire.project where Alamofire is a linked framework to the AppName.project

What is the source of your access token were you abusing the API:https://developer.apple.com/forums/thread/702228

HomeScreen & SignInView will inherit the outer most NavigationView, no need to nest the NavigationView them. struct ContentView: View { @EnvironmentObject var viewModel: AppViewModel var body: some View { NavigationView { if viewModel.signedIn { HomeScreen() .navigationBarHidden(true) } else { SignInView() .navigationBarHidden(false) .navigationBarTitle("Sign In", displayMode: .inline) } } .onAppear { viewModel.signedIn = viewModel.isSignedIn } } }

Pay the bill or comply with the rules.

Do you have a duel display on the Mac already connected?

https://developer.apple.com/documentation/uikit/uiscreen/1617812-screens UIScreen.screens Discussion The returned array includes the main screen plus any additional screens connected to the device. The main screen is always at index 0. Not all devices support external displays. Currently, external displays are supported by iPhone and iPod touch devices with Retina displays and iPad. Older devices, such as the iPhone 3GS do not support external displays. didConnectNotification This notification is posted when a new screen is connected to the device.  Discussion Connection notifications are not sent for screens that are already present when the application is launched. The application can instead use the screens method to get the current set of screens at launch time. The object of the notification is the UIScreen object representing the new screen. There is no userInfo dictionary.

Is this homework?

No crashes on Xcode 13.3 playground - it just locks the IDE up after a few runs.

This is a c++ method of the atomic includes. You will have to probably implement an Objective/C++ wrapper around the method & then export it to swift via bridging file: atomic: references https://www.cplusplus.com/reference/atomic/atomic/

You really don't needed it there because it is private

Cannot use it like that it will become a nested reference onto itself.             LocationsView()                 .environmentObject(vm) // Any child view will have access to this environment object by using  @EnvironmentObject var vm: LocationsViewModel

Still not relying on UIKit directly you can still make this a pure SwiftUI implementation by using a SwiftUI TextEditor and FocusValue & FocusBinding for iOS 14+ to do what FocusState is doing at iOS 15+. https://swiftwithmajid.com/2021/03/03/focusedvalue-and-focusedbinding-property-wrappers-in-swiftui/

Best to use: lazy var accountType = "Account" @FetchRequest( sortDescriptors: [NSSortDescriptor(keyPath: \.displayOrder, ascending: true)] , predicate: NSPredicate(format: "(hidden < %@) AND (type == %@)", argumentArray: [1, accountType]) , animation: .default ) private var items: FetchedResults<JMAccount> or @FetchRequest( sortDescriptors: [NSSortDescriptor(keyPath: \.displayOrder, ascending: true)] , predicate: NSPredicate(format: "(hidden < %@) AND (type == %@)", argumentArray: [1, "Account"]) , animation: .default ) private var items: FetchedResults<JMAccount>

You can do the something natively in swiftUI without using UIKit. See here:https://developer.apple.com/documentation/swiftui/textfield/focused(_:equals:) struct LoginForm { enum Field: Hashable { case usernameField case passwordField } @State private var username = "" @State private var password = "" @FocusState private var focusedField: Field? var body: some View { Form { TextField("Username", text: $username) .focused($focusedField, equals: .usernameField) SecureField("Password", text: $password) .focused($focusedField, equals: .passwordField) EmptyView()                   .emptyState(focusedField == .username) {                           Text("Please enter a user name.")                                 .foregroundColor(.red)                                 .font(.footnote)                         } Button("Sign In") { if username.isEmpty { focusedField = .usernameField } else if password.isEmpty { focusedField = .passwordField } else { handleLogin(username, password) } } } } } struct EmptyStateViewModifier<EmptyContent>: ViewModifier where EmptyContent: View {     var isEmpty: Bool     let emptyContent: () -> EmptyContent     func body(content: Content) -> some View {         if isEmpty {             emptyContent()         } else {             content         }     } } extension View {     func emptyState<EmptyContent>(_ isEmpty: Bool,                                     emptyContent: @escaping () -> EmptyContent) -> some View where EmptyContent: View {         modifier(EmptyStateViewModifier(isEmpty: isEmpty, emptyContent: emptyContent))     } }

If appears that after app launch, a view controller is being presented leading up to the crash
