Hello, I have an app which I have enabled VoIP entitlement and implemented all the CallKit and PushKit registries and delegates. I can successfully get a VoIP token. I can successfully send VoIP push notifications (and receive them via the PushKit delegate function) and then report an incoming call via CallKit, but only while my app is in the foreground. I have checked the entitlement in XCode and the Info.plist directly, and they both (as expected) show voip as a background mode. The VoIP notification is being sent via AWS SNS and everything works while the app is in the foreground. I cannot understand why the app is not waking up while in the background. This is the VoIP notification sent via SNS: aps: { alert: "Intercom call", "content-available": 1 } SNS Message Attributes: 'AWS.SNS.MOBILE.APNS.TOPIC': { DataType: 'String', StringValue: `${bundleId}` }, 'AWS.SNS.MOBILE.APNS.PUSH_TYPE': { DataType: 'String', StringValue: 'voip' }, 'AWS.SNS.MOBILE.APNS_VOIP.TTL': { DataType: 'String', StringValue: '0' }, 'AWS.SNS.MOBILE.APNS_VOIP_SANDBOX.TTL': { DataType: 'String', StringValue: '0' }, 'AWS.SNS.MOBILE.APNS.PRIORITY': { DataType: 'String', StringValue: '10' } As I say, func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType) async works correctly when in the foreground. I cannot see any reason why it would not work from the background. I am also receiving normal remote notifications correctly foreground and background.

Hi, for my app, which supports minimum iOS 14, I'm getting frequent test flight crashes in regards to this: SwiftUI: protocol witness for Projection.get(base:) in conformance WritableKeyPath<A, B> + 24. (Full thread crash at end.) The crash logs don't indicate specifically where this occurs, only that it occurs in SwiftUI directly. I was advised by someone that this was due to using indices in ForEach and have since modified any ForEach statements to now use Identifiable arrays instead of possibly none-constant index range. I have noticed that these crashes only occur in iOS 14.* and 15.*. Does anyone know another possible reason for this type of crash or an iOS < 16 fix?
