A detailed description of the steps to reproduce the issue

When selecting Platpus OAuth Bank (or any bank for that matter), we see the following warning banner:

We have configured our redirect uri in the Plaid dashboard.

Assume that our uri is the following:

https://mycompany.com/n/native-oauth-plaid-link-completed

in Xcode, we have set up applinks like so:

When we create the link token we pass the redirectUrl "https://mycompany.com/n/native-oauth-plaid-link-completed".

We have an apple-app-site-association file being hosted. Here is the basic outline of our apple-app-site-association:

What you expected to see?

I expected that our redirect uri was set up correctly and the banner in the screenshot above stating we have a missing redirect_uri is not present.

What you saw instead?

The banner saying we have potential issues with our redirect_uri.

Please do not include your API secret or public_key in any issue.

A detailed description of the steps to reproduce the issue

1. Make sure a redirect URI has been setup as a Universal Link in your aasa file and registered in the Plaid Dashboard following docs here
2. Create a link_token following the docs here
3. Let the link_token expire
4. From one of the iOS Plaid sample apps included in this repository (I used LinkDemo-SwiftUI) , use the expired link_token to create a LinkTokenConfiguration instance for calling Plaid.create()
5. Run the sample app and click on Open Plaid Link
6. Notice an error screen is rendered (see screenshot below) and an error is returned that indicates a redirect URI must be configured in the developer dashboard which is not indicative of the true issue (an expired link_token)

What you expected to see?

An error that mentions the link_token is expired

What you saw instead?

An error that mentions a redirect URI has not been configured in the Plaid dashboard:

exit with ExitError(errorCode: LinkKit.ExitErrorCode.invalidRequest(INVALID_FIELD), errorMessage: "OAuth redirect URI must be configured in the developer dashboard.

I'm seeing this warning now on the latest release.
"'custom' is deprecated: Presenting Link with modalPresentationStyle .overFullScreen or .fullScreen is no longer supported. You may experience UI issues if you present Link using those modalPresentationStyles."

However this is the main way you provide to present Plaid is SwiftUI. How then should we present it. I can't get .viewController to work.

A detailed description of the steps to reproduce the issue

Using a link token created against the identity_verfication product, the iOS Plaid Link SDK is unable to load the start of the product workflow due to an error received from a request to https://sandbox.plaid.com/link/workflow/event fired shortly after a successful https://sandbox.plaid.com/link/workflow/start request. The identity_verfication request is then stuck in-progress and cannot be cancelled from the Plaid Dashboard.

1. Make sure a redirect URI has been setup as a Universal Link in your aasa file and registered in the Plaid Dashboard following docs here
2. Create a link_token following the docs here
3. From one of the iOS Plaid sample apps included in this repository (I used LinkDemo-SwiftUI) , use the link_token given back from the cURL request made in step 2 to create a LinkTokenConfiguration instance for calling Plaid.create().
4. Run the sample app and click on Open Plaid Link
5. Notice the view presenting Plaid's content is stuck on a white screen (see screenshot below) and an error appears in the console mentioning an invalid workflow session id:

2023-10-17 17:08:55 +0000 com.plaid.linkdemo.ios.swiftui/ ERROR: Error sending webviewFallbackOpen event: linkError(Optional(Workflow.LinkApiError(displayMessage: nil, documentationURL: nil, errorCode: Optional("INVALID_FIELD"), errorMessage: Optional("invalid workflow session id"), errorType: Optional("INVALID_REQUEST"), requestID: nil, suggestedAction: nil)), Optional("{\n  \"display_message\": null,\n  \"documentation_url\": \"https://plaid.com/docs/?ref=error#invalid-request-errors\",\n  \"error_code\": \"INVALID_FIELD\",\n  \"error_message\": \"invalid workflow session id\",\n  \"error_type\": \"INVALID_REQUEST\",\n  \"request_id\": \"WkEKaKgt6zAaW0w\",\n  \"suggested_action\": null\n}"))

6. If you perform step 4 with a proxy running, you'll notice 2 requests are fired:

A request to https://sandbox.plaid.com/link/workflow/start that successfully returns a https://verify-sandbox.plaid.com/plaid/verify/foo URL in the response which when copy/pasted into a web browser looks great, but is not rendered in-app due to the failure below.

A request to https://sandbox.plaid.com/link/workflow/event with request body:

3 {
  29: ""
}

Failing on a 400 with response body:

{
  "display_message": null,
  "documentation_url": "https://plaid.com/docs/?ref=error#invalid-request-errors",
  "error_code": "INVALID_FIELD",
  "error_message": "invalid workflow session id",
  "error_type": "INVALID_REQUEST",
  "request_id": "DBhqBNTHSPD9r1L",
  "suggested_action": null
}

What you expected to see?

I expect to see the start of the identity verification flow as defined by the template I created in the Plaid Dashboard and referenced in my create token cURL request.

Some Notes:

• The Plaid Link Android SDK does not exhibit this bug, but it also does not fire the https://sandbox.plaid.com/link/workflow/event request like the iOS SDK does. This seems to be the root of this problem since the https://sandbox.plaid.com/link/workflow/start request which is fired before the event request does not return a workflow session id in its response for the SDK to then use when calling https://sandbox.plaid.com/link/workflow/event.
• I also tested this against the 5.0.0-beta1 branch and the bug was still present.
• The auth and identity products do not exhibit this bug, but I noticed those products got a workflow session id back in the response from their calls to https://sandbox.plaid.com/link/workflow/start which they then passed along in the request body to https://sandbox.plaid.com/link/workflow/event and therefore their event requests never failed.

What you saw instead?

An error in the console:

2023-10-17 17:08:55 +0000 com.plaid.linkdemo.ios.swiftui/ ERROR: Error sending webviewFallbackOpen event: linkError(Optional(Workflow.LinkApiError(displayMessage: nil, documentationURL: nil, errorCode: Optional("INVALID_FIELD"), errorMessage: Optional("invalid workflow session id"), errorType: Optional("INVALID_REQUEST"), requestID: nil, suggestedAction: nil)), Optional("{\n  \"display_message\": null,\n  \"documentation_url\": \"https://plaid.com/docs/?ref=error#invalid-request-errors\",\n  \"error_code\": \"INVALID_FIELD\",\n  \"error_message\": \"invalid workflow session id\",\n  \"error_type\": \"INVALID_REQUEST\",\n  \"request_id\": \"WkEKaKgt6zAaW0w\",\n  \"suggested_action\": null\n}"))

The simulator stuck on a white screen and the identity verification requests stuck in-progress in the Plaid Dashboard

I haven't faced soo slow package loading ever for any other library where its been 2 hours and the package progress keeps on reseting once it reaches 11%.

What you expected to see?

SPM package should resolve in minutes. It depends on internet connection speed but i have million other projects using countless dependencies but no one stuck's this bad.

What you saw instead?

Package not resolving.

When going through the linking process and then verifying identity step when pressing cancel we got an exit call back without an error
but if we hit the 'x' button we get an exit callback with an unknown error
plz check screenshot for more info

I see a PrivacyInfo.xcprivacy file was recently added to this repository to help app developers to understand the API use and data-collection practices of your SDK. However there is some info missing in the PrivacyInfo.xcprivacy file. The NSPrivacyCollectedDataTypePurposes for NSPrivacyCollectedDataTypeUserID seems to be an empty array.

This can also be seen when generating a privacy report using the LinkKit SDK.

What you expected to see?

I expect that a reason for collection the data will be entered in the PrivacyInfo.xcprivacy file as described in this document by Apple - https://developer.apple.com/documentation/bundleresources/privacy_manifest_files/describing_data_use_in_privacy_manifests.

In latest plaid link kit version 5.3.2 there is wrong positioning of plaid screens

• Screens are cropped and not 100% height on initial start
• There is a slow animation with loading circle on initial start

Expected

• Plaid screens not cropped
• Plaid screens load faster

Now

• Plaid screens cropped and looks weird
• Plaid screens starts very slow after handler.open executed

A detailed description of the steps to reproduce the issue

While converting some of our dependencies from dynamic libraries to static to reduce app size and app launch time, we notice that LinkKit is distributed as dynamic framework. It would if the xcframework included the -make_mergeable linker flag that adds a new load command to the dylib, making it a mergeable library, that could be linked to app binary, just like a static library.

• quickly dismiss plaid view
• check if onExit callback is triggered

What you expected to see?

onExit has been triggered

What you saw instead?

Is there any way to test end to end in production without linking our own personal bank account? For example, we have a prod smoke testing account that we can use, but if we want to test the app to app flow between our app and say Chase bank to ensure redirects are working, linking is successful, etc., we have to link our own personal bank accounts.

Does Plaid provide any support for somehow smoke testing in production without using personal data?

A detailed description of the steps to reproduce the issue

• Start link flow with Plaid OAuth app2app (in this case - Chase)
• User kills our app
• User's banking app routes them back to our app
• Use Plaid's resumeAfterTermination

Can you provide instructions or example code on using this API?

What you expected to see?

A continuation of the OAuth flow.

What you saw instead?

It appears to be some sort of internal TODO message left by developers?

Some Relevant Code

            handler.resumeAfterTermination(from: url)
            let modalPresentation: LinkKit.PresentationHandler = { [weak self] linkVC in
                guard let self else { return }
                linkVC.isModalInPresentation = true // prevents swiping to dismiss
                self.present(linkVC, animated: true)
            }
            handler.open(presentUsing: .custom(modalPresentation))
