I've developed an app in SwiftUI where I also use a chat with Parse LiveQuery. The chat is working perfectly in real time until the app goes in background or the phone screen is closed. If I receive a notification for a new message and I open the app from the notification then the LiveQuery stopes working and I recieve the error : "Parse LiveQuery: Error processing message: Optional(POSIXErrorCode: Software caused connection abort)"
I register the Message class
class Message: PFObject, PFSubclassing {
@NSManaged var message : String
@NSManaged var receiver : PFObject
@NSManaged var thread_id : PFObject
@NSManaged var produs : PFObject
@NSManaged var sender : PFObject
@NSManaged var picture : PFObject
class func parseClassName() -> String {
return "Message"
}
}
On the ChatView I have .onReceive where I start the function for chat and liveQuery
var messagesQuery: PFQuery<Message> {
return (Message.query()?
.whereKey("thread_id", equalTo: self.mainThread_obj)
.order(byDescending: "createdAt")) as! PFQuery<Message>
}
self.StartMessagesLiveQuery(messagesQuery: messagesQuery)
The func StartMessagesLiveQuery is:
let subscription: Subscription<Message> = Client.shared.subscribe(messagesQuery)
subscription.handle(Event.created) { query, object in
print("Live Query Trigered")
print(object)
DispatchQueue.global(qos: .background).async {
///reading object and appending to array}}
The only problem is when the app is opened from Notification.
I've there any way to force ParseLiveQuery to reconnect?

I think i’ve solved it. I've modified function StartMessagesLiveQuery:
func StartMessagesLiveQuery(messagesQuery: PFQuery<Message>){}
Inside the function I had:
let subscription: Subscription<Message> = Client.shared.subscribe(messagesQuery)
subscription!.handle(Event.created) { query, object in ... }
Now i’ve modified and put inside the Class
var subscription: Subscription<Message>?
var subscriber: ParseLiveQuery.Client!
and in the function i’ve modified with:
subscriber = ParseLiveQuery.Client()
subscription = subscriber.subscribe(messagesQuery)
