When integrating the Wallet Extension, after clicking my app icon from the "From Apps on Your iPhone" list, I encountered the message: "Cannot Add Card. '***' is not responding. Wait a few minutes and try again. If the problem continues, contact the card issuer's customer service" instead of the configured login page appearing as expected.

What could be causing this issue, and how should I resolve it?

I have solve this problem. I need to set NSExtensionPrincipalClass with $(PRODUCT_MODULE_NAME).xxxUIExt in swift. The class xxxUIExt should be write using swift too.
