Hi, My iOS app allows a user to perform a rather expensive cloud operation (costs me 10 cents per time) and I want to ensure they can only do it once a day across all of their iOS devices. The marketing will make it clear this is how it will work so users won't be surprised. While most will only have one iPhone in practice, with my subscription pricing I'd lose money the second someone started doing it on a second device. I could solve this using Sign in with Apple to ensure there is a 1:1 correlation between Apple ID with paid subscription and a user account in my system that I could track usage against but I'd like to avoid users having to sign in at all since it would serve no purpose from a user perspective. identifierForVendor won't work since it's different across every device the same user has Is there something in StoreKit v2 receipts or transaction data that would be stable longterm and have the same result across all devices using the same Apple ID? I don't actually want any info about the user, just a stable anonymized identifier to see they are the same user on different devices. I could also go with a consumable in-app purchase but I don't think users would like this pricing model for this app. Thanks! Colin

Hi, calls to URLSession for an IPv6 only domain (i.e. only an AAAA DNS record) within my app are failing even though the same domain name works in Safari. This is on a device with both an IPv4 and IPv6 connection when iCloud Private Relay is enabled and when it is not. I'm trying to obtain the external IPv4 and IPv6 addresses of the user's device from my app using ipify.org's api4.ipify.org (IPv4), api64 (6 to 4) and api6 (IPv6) addresses. The issue I am having is within my app the api64 call always returns an IPv4 address and the api6 call just fails outright, resulting in a throw "A server with the specified hostname could not be found." api6.ipify.org only has an AAAA DNS record. But everything works right on the same device in Safari. In Safari: api4.ipify.org -> IPv4 api64.ipify.org -> IPv6 (since device has IPv6 connectivity) api6.ipify.org -> IPv6 In my app though: api4.ipify.org -> IPv4 api64.ipify.org -> IPv4 (but should return an IPv6 address, like for Safari) api6.ipify.org -> IPv6 (fails...domain name not found) Tried with cellular only connection (device has two public IPv6 addresses assigned) and from WiFi (device has both a private IPv4 and a private IPv6 address) and same results. Happening in both iOS 17.03 and 16.7.1. I am having the exact same results when using other sites similar to ipify.org. 6to4 only returns an IPv4 address and AAAA record only domains fail, so not something specific to ipify.org. Here's the code block that is failing within my app when api6.ipify.org is used and returns the wrong answer when api64 is used. Thank you! Task { do { let (data, _) = try await URLSession.shared.data(from: URL(string: "https://api<insert 4, 64 or 6>.ipify.org")!) self.statusPublicIPv6 = String(data: data, encoding: .utf8) ?? "" } catch { print(error.localizedDescription) } }

Hi, The "Siri & Search" option is listed in my app's settings and I'd like to know how to remove it. I'm pretty sure it wasn't listed when I first started developing my app over a year ago and I never added any Siri related entitlements to my app, not sure when it started being there. It seems half of the apps on my device (from other developers) have this listed, other half do not, so it's not there by default. I've checked my entitlements file, nothing related to Siri. Checked capabilities, nothing there either related to Siri. I know my users could go and manually block the app's data from being accessible but I'd rather remove the option entirely and definitely don't want it on by default. Shows up on at least iOS 15 and iOS 16. Thanks! Colin
