When using upload/uploadsession I get a sessionDeinitialized from alamofire in Swift

Ah gotcha. I was reading the doc and it seemed like if I just used DropboxClient with a shortlived token, it would do that. I have since rewritten the code, different from how the docs have it since I was not having any luck getting that to work. Edited this code to be macOS.

Now to figure out why it creates a duplicate window. Think it has something to do with the NSView but not sure.

For anyone that comes  across this. Here is my code, it works but has that duplicate app window I mentioned earlier.

//ContentView.swift
import SwiftUI
import SwiftyDropbox
import AppKit

struct ContentView: View {
    
    @State var isShown = false
    
    var body: some View {
        HStack {
            VStack {
                    
                    Button(action: {
                        self.isShown.toggle()
                    }) {
                        Text("Login to Dropbox")
                            .padding(.top)
                    }

                    DropboxView(isShown: $isShown)
                    
                    Button {
                        if let client = DropboxClientsManager.authorizedClient {
                            print("successful login")
                        } else {
                            print("Error")
                        }
                    } label: {
                        Text("Test Login")
                            .padding(.bottom)
                            
                    }
                    
                }
                .onOpenURL { url in
                    let oauthCompletion: DropboxOAuthCompletion = {
                        if let authResult = $0 {
                            switch authResult {
                            case .success:
                                print("Success! User is logged into DropboxClientsManager.")
                                
                            case .cancel:
                                print("Authorization flow was manually canceled by user!")
                            case .error(_, let description):
                                print("Error: \(String(describing: description))")
                            }
                            NSApplication.shared.setActivationPolicy(.prohibited)
                        }
                    }
                    DropboxClientsManager.handleRedirectURL(url, completion: oauthCompletion)
            }
        }
    }
}

struct DropboxView: NSViewControllerRepresentable {
    
    typealias NSViewControllerType = NSViewController
    
    @Binding var isShown: Bool
    
    func updateNSViewController(_ nsViewController: NSViewController, context: Context) {
        if isShown {
            let scopeRequest = ScopeRequest(scopeType: .user, scopes: ["account_info.read", "files.metadata.write", "files.metadata.read", "files.content.write", "files.content.read"], includeGrantedScopes: false)
            
            DropboxClientsManager.authorizeFromControllerV2(
                sharedApplication: NSApplication.shared,
                controller: nsViewController,
                loadingStatusDelegate: nil,
                openURL: { (url: URL) -> Void in NSWorkspace.shared.open(url) },
                scopeRequest: scopeRequest)
        }
    }
    
    func makeNSViewController(context _: Self.Context) -> NSViewController {
        return NSViewController(nibName: "DBViewController", bundle: nil)
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

//YOURApp.swift
import SwiftUI
import SwiftyDropbox

@main
struct dropboxClientApp: App {
    
    init() {
        DropboxClientsManager.setupWithAppKeyDesktop("app_key")
    }
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
}

Then you need to make a file type of View. I called mine "DBViewController" in the contentview file at the bottom. After that follow these instructions

1. Make sure that you have a nib file named DBViewController.xib in your Xcode project.

2. Open the nib file, select the File's Owner object, and set its class to NSViewController in the Identity Inspector.

3. Connect the view outlet of the File's Owner to the view object in the nib file.

4. In the makeNSViewController function of DropboxView, instantiate the DBViewController from the nib file using the init?(nibName:bundle:) initializer.
