My server that backs my Message Filter Extension stopped receiving messages last night.
I thought maybe I had broken something in the iOS code, even though I hadn't touched any of the logic related to filtering. So I rolled back my code to a previous version that was definitely working in both test and production and ran it on my test device, setting a breakpoint on the first line of the
func handle(_ queryRequest: ILMessageFilterQueryRequest, context: ILMessageFilterExtensionContext, completion: @escaping (ILMessageFilterQueryResponse) -> Void)
method in the extension. When sending a message to it from an unknown number, the breakpoint is never even hit.
To ensure it was somehow not my code, I started a new blank app and added the Message Filter Extension target. Running it on my test device, it also doesn't ever hit the breakpoint.
Is there some Apple service involved in determining whether to send unknown sender messages to Message Filter Extensions that might be down. Maybe it's a beta issue? I'm on iOS 18.1 Beta 4. But it seems odd that all of my users' devices would be encountering a beta-related issue at essentially the same time.
