.package(url: "https://github.com/feather-framework/feather-push-fcm", exact: "1.0.0-rc.1"),

Add FeatherPushFCM to the target dependencies:

.product(name: "FeatherPushFCM", package: "feather-push-fcm"),

API documentation is available at the following link.

let client = PushClientFCM(
    httpClient: httpClient,
    credentials: credentials
)

let notification = PushNotification(
    title: "New message",
    body: "You have a new message.",
    deepLink: "my-app://messages/1"
)

try await client.send(notification: notification, to: .topic("messages"))

try await client.send(
    notification: notification,
    to: .deviceToken("device-registration-token")
)

The package uses Logger.current from swift-log for FCM request logging. Use withLogger to scope the logger for an operation; calls to Logger.current within that scope use the scoped logger.
