Sending a LiveActivity start notification

[Urkman]

Hello,

I want to send a LiveActivity start notification. But this is not working.
I use this code to send the notification:

let notification = APNSStartLiveActivityNotification(
                expiration: .immediately,
                priority: .immediately,
                appID: liveActivityAppId,
                contentState: drivingState,
                timestamp: Int(Date().timeIntervalSince1970),
                staleDate: nil,
                apnsID: nil,
                attributes: DrivingAttributesPayload(id: drivingState.vehicleId, name: drivingState.vehicleName),
                attributesType: "DrivingAttributes",
                alert: .init()
            )

let request = APNSRequest(
            message: notification,
            deviceToken: deviceToken,
            pushType: .liveactivity,
            expiration: notification.expiration,
            priority: notification.priority,
            apnsID: notification.apnsID,
            topic: liveActivityTopic,
            collapseID: nil
        )
        return try await apns.client.send(request)

But nothing arrives at the device.

When I use Apples notification console, it is working.
With this Payload:

{"aps":{"timestamp":1765518754,"event":"start","content-state":{"vehicle_id":"1234567890","vehicle_name":"Name"},"alert":{"title":"title","body":"body"},"attributes":{"id":"1234567890","name":"Name"},"attributes-type":"DrivingAttributes"}}

PushToken is certified and it's the same.
liveActivityAppId is the same as in the console.
drivingState is also the same as the content-state in the payload.
liveActivityTopic is same as liveActivityAppId, but with ".push-type.liveactivity"

So, where is my error?

I'm experiencing the same issue. Validated my message against the example payload in the Apple docs for remotely starting a live activity.

I noticed there's no convenience method on APNSClient like sendPushToStartLiveActivityNotification(_:pushToStartToken:)-- does that mean that starting live activities isn't supported in this library?

[kylebrowning]

It's definitely supported. Likely a bug.

I can take a look Monday, but open to PRs

@kylebrowning Not sure if this is this issue, but when I use the localized APNSAlertNotificationContent.StringValue configuration for title and body it generates an aps.alert payload that differs from the example given in the Apple reference.

Here's a snippet of my code:

alert: .init(
    title: .localized(
        key: "@ is nursing",
        arguments: ["Persephone"]
     ),
     body: .localized(
         key: "@ is nursing",
         arguments: ["Persephone"]
     ),
     sound: .default
)

Here's the aps.alert payload generated from APNSAlertNotificationContent:

"alert":{
    "loc-key":"@ is nursing",
    "loc-args":[
        "Persephone"
    ],
    "sound":"default",
    "title-loc-args":[
        "Persephone"
    ],
    "title-loc-key":"@ is nursing"
}

And here's the shape of aps.alert from the Apple example:

"alert": {
    "title": {
        "loc-key": "%@ is on an adventure!",
        "loc-args": [
            "Power Panda"
        ]
    },
    "body": {
        "loc-key": "%@ found a sword!",
        "loc-args": [
            "Power Panda"
        ]
    },
    "sound": "chime.aiff"
}

@Urkman @kylebrowning

And after all that, I found that you just need to provide a title, body, and sound in the APNSAlertNotificationContent you provide... 😅

This code starts a live activity for me on 6.2.0.

let notification = APNSStartLiveActivityNotification(
    expiration: .immediately,
    priority: .immediately,
    appID: bundleID,
    contentState: contentState,
    timestamp: Int(Date.now.timeIntervalSince1970),
    attributes: attributes,
    attributesType: "DurationActivityAttributes",
    alert: .init(
        title: .raw("Hey"),
        body: .raw("You"),
        sound: .fileName("default.aiff")
    )
)

let request = APNSRequest(
    message: notification,
    deviceToken: deviceToken,
    pushType: .liveactivity,
    expiration: notification.expiration,
    priority: notification.priority,
    apnsID: notification.apnsID,
    topic: notification.topic,
    collapseID: nil
)

let response = try await client.send(request)

Note: using APNSAlertNotificationSound.default in the initializer for APNSAlertNotificationContent doesn't successfully start the live activity.

And the only user-facing context where I've seen the values for title and body come through is on Apple Watch when the live activity starts.
