If I only have one product item in Apple Pay, how would I detect a total? My app is a donation platform, so I don't need to actually ship anything, but would like contact info. I have a number of errors that I have tried to figure out to debug to no avail. Any help is appreciated.Also I keep getting this error (this was the same as the sample code given from WWDC).This is in my BuyTicketViewController.swift file. if PKPaymentAuthorizationViewController.canMakePaymentsUsingNetworks(BuyTicketViewController.paymentNetworks) { let button = PKPaymentButton(type: .Buy, style,: .Black) button.addTarget(self, action: applePayButtonPressed, forControlEvents: .TouchUpInside) button.center = applePayView.center button.autoresizingMask = [.FlexibleLeftMargin, .FlexibleRightMarin] applePayView.addSubview(button) } }The error says 'expected declaration.'The sample says to use else (for traditional checkout). When I put that it, it breaks the rest of my code and I get lots of errors.line 8 - eror on MerchantIDline 9 - error

I am encountering the following issue while working with app group preferences in my Safari web extension: Couldn't read values in CFPrefsPlistSource<0x3034e7f80> (Domain: [MyAppGroup], User: kCFPreferencesAnyUser, ByHost: Yes, Container: (null), Contents Need Refresh: Yes): Using kCFPreferencesAnyUser with a container is only allowed for System Containers, detaching from cfprefsd. I am trying to read/write shared preferences using UserDefaults with an App Group but keep running into this error. Any guidance on how to resolve this would be greatly appreciated! Has anyone encountered this before? How can I properly configure my app group preferences to avoid this issue?

I was wondering what the best way of setting up an App Group with a subset of my data for display on the watch.My App was originally written with Core Data. Kelly

If I use SubscriptionStoreView.init(groupID), it seems to be able to look up all the Products that have that subscription group ID. But I don't see any public method for doing that myself. Am I missing something, or is SubscriptionStoreView using a private method to do this lookup? I know that historically it has always been necessary to know the product IDs of all the products you want to sell; you have never been able to ask Store Kit to give you a list. SubscriptionStoreView doesn't seem to have this limitation, which is a bit surprising.

Hello, I’m experiencing a strange issue with a newly created Subscription Group in my iOS app. For all my existing subscription groups, everything works perfectly — initial purchase, renewals, cancellations, all notifications arrive normally. But for this one newly created group, the first purchase never triggers any server notification from App Store Server Notifications (ASSN). ⸻ 📘 Problem Summary • I created a new Subscription Group in App Store Connect. • The products are all Approved and Published for over a week. • Users can successfully purchase the subscription in production. • The purchase is shown as Purchased in the App Store purchase UI. • The receipt can be fetched locally on device. • But my server receives no notifications, including: • DID_RENEW • DID_CHANGE_RENEWAL_STATUS • SUBSCRIBED • ONE_TIME_CHARGE • CONSUMPTION_REQUEST • etc. The old subscription groups still send notifications normally, so the notification URL and server infrastruct

Hello,Based on what I read here promoted IAP's have be named differently than default IAPs to help with ASO.But it's not clear to me if I have to place the promoted IAPs in a separate group or not?e.g. under my non-promoted IAP subscription group I have the following:Arrange your subscriptions in descending order, starting with the option that offers the highest level of service. You can add more than one subscription to each level. This order will determine your subscription’s upgrade and downgrade options.1. Standard - One Week1. Standard - One Month1. Standard - One Year2. Lite - One Week2. Lite - One Month2. Lite - One YearSo do I now add a promoted IAP with optimised title and description inside the same group? Or in a different group?1. Standard - One Week1. Standard - One Month1. Standard - One Year2. Lite - One Week2. Lite - One Week - Promoted2. Lite - One Month2. Lite - One YearThank you,Houman
