Issue Retrieving Bound Cards in Wallet Extension Non-UI Extension

Hi,

I’m encountering an issue in my app’s Wallet Extension, specifically within the Non-UI Extension, where we are unable to retrieve payment passes bound to a user’s account. The same code that successfully retrieves these bound cards in the main app does not work when used in the Non-UI Extension.

Case-ID: 8932090

Steps to Reproduce:

1. Set up In-App Provisioning:
   Ensure that the app has the necessary In-App Provisioning permissions. This functionality works correctly in the main app, confirming that the permissions are properly configured.

2. Configure Wallet Extensions:
   Follow the Wallet Extensions documentation to configure the app, including all required settings for the Non-UI Extension.

3. Add Code to Retrieve Payment Passes:
   In the main app’s LoginView, implement the following code in the handleLogin() method to retrieve payment passes:

   // Get the identifiers of payment passes that already exist in Apple Pay.
   paymentPassLibrary = self.passLibrary.passes(of: .secureElement)
   
   for pass in paymentPassLibrary {
       if let identifier = pass.secureElementPass?.primaryAccountIdentifier {
           if pass.isRemotePass && pass.deviceName.localizedCaseInsensitiveContains("Apple Watch") {
               remotePassIdentifiers.insert(identifier)
           } else if !pass.isRemotePass {
               passIdentifiers.insert(identifier)
           }
       }
   }
   

4. Verify Functionality in Main App:
   Run the app and verify that the code successfully retrieves the payment passes bound to the user’s account.

5. Implement Code in Non-UI Extension:
   Add the same code to the Non-UI Extension, specifically in the WNonUIExtHandler class within the override func status(completion: @escaping (PKIssuerProvisioningExtensionStatus) -> Void) method.

6. Test in Wallet Extension:
   Run the Wallet Extension and observe that the payment passes are not retrieved when the code is executed in the Non-UI Extension.

Has anyone encountered a similar issue or can provide insight into why the code might not work in the Non-UI Extension compared to the main app?

Support Information:

• iOS Version: 17.5.1
• Development environment: Xcode 15.4 (15F31d), macOS 14.3 (23D56)

Any help or suggestions would be greatly appreciated. Thank you!
