Hi, I am stuck at the same where I am unable to initialize PKIssuerProvisioningExtensionPassEntry as no init method and properties are read only. Thought I found a way like public class ExtentionPassEntryHandler : PKIssuerProvisioningExtensionPaymentPassEntry - you can create a subclass of PKIssuerProvisioningExtensionPaymentPassEntry which has an initializer method but after that I am unable to go ahead. did you find any solution for this.? Apple in-app provisioning doc has no detail info.
