Hi&nbsp;Mull999,
I'll be happy to help with any issues you're having with the Dropbox Swift SDK, but I'll need some more information. Please reply with:
- the name and version of the platform and SDK/library you are using- the steps to reproduce the issue, including relevant code snippet(s), but don't include any access or refresh token(s)- the full text of any error or unexpected output

Hi iNeilThanks for responding. &nbsp;I should say at the outset that I am a hobby coder and very much in learning mode. &nbsp;I have a shopping list app that works as intended and now I want to be able to file the data as backup using my Dropbox files. &nbsp;So I have started to build a test app to learn how to get access to Dropbox through a SwiftUI app. &nbsp;I read the advice given on Github SwiftyDropbox version10.0. and implemented the requirementsI successfully attached the package SwiftyDropbpox 10.0.7 to my test app. &nbsp;However I get an error in my AppDelegate, as follows:-func application(_application: UIApplication, didFinishLaunchingWithOptions launchOptions: DropboxClientsManager.setupWithAppKey("&lt;APP_KEY&gt;") -&gt; Bool { return true }The error says setupWithAppKey is not a member type of DropboxClientsManager.The app fails at that point so I have not got further into testing. &nbsp; However, I am thinking perhaps the SwiftyDropbox package is not compatible with SwiftUI.I hope you can offer some advice.&nbsp;

Thanks for following up. It should be possible to use SwiftyDropbox in a SwiftUI project. The SwiftyDropbox readme does have some notes throughout about how to use it in SwiftUI.
&nbsp;
For reference, how did you install the SwiftyDropbox package?
&nbsp;
Also, do you have 'import SwiftyDropbox' in your AppDelegate?
&nbsp;
Finally, is that the actual 'func application...' code you have? It looks like it may be a copy/paste mistake, as it doesn't appear to be a valid definition (e.g., it's missing a ")", etc.). I believe it should look something like this:
&nbsp;
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -&gt; Bool {
        DropboxClientsManager.setupWithAppKey("&lt;APP_KEY&gt;")
        return true
    }
&nbsp;

Hi GregI used Apple Package Manager to integrate SwiftyDropbox into my test app. &nbsp;Yes I have the import statement in the AppDelegate.I replaced my func application(...) with your version above and that had a positive result. &nbsp;The app still failed but at a location inside the SwiftyDropbox package.I cannot find a way to insert a screen shot of the point of failure - my inexperience I guess (still learning at 80 years old!!!). &nbsp;However the fail is in the DropboxClientsManager extension within the init() in this line of code :-self.dauthRedirectURL = URL(string: "db-\(appKey)://1/connect")!Fail message is Unexpectedly found nil while unwrapping an Optional.I have got the appKey in the infoplist as per the instructions in SwiftyDropbox so I am not sure what is causing this problem

This particular error should depend on the app key value you pass to setupWithAppKey (not the instance you set in the plist).
&nbsp;
Can you confirm you're passing your app key (and just the app key) to DropboxClientsManager.setupWithAppKey? Note that &lt;APP_KEY&gt; is just a placeholder for demonstration purposes, and you should not include the angle brackets in your actual code. (If you include the angle brackets, or other invalid characters, that would result in an invalid URL string which would cause the URL initializer to return nil which would cause the unwrapping error you're getting.)
&nbsp;
To be clear, it would look like this:
DropboxClientsManager.setupWithAppKey("abc123")
where abc123 would be replaced with your actual app key.
