I have registered EventHandlerForClass. My App running 24*7 hr and updating content from backedless.
It was updating content instantly for few days but suddenly stop working. Could you please let me know there is any timeline for listner

Hello @Vinod_Sahu,
Could you please provide a simple code sample that reproduces your issue because we cannot reproduce this problem.
Regards,
Olha
let eventListner = Backendless.shared.data.of(ConciergeServices.self).rt
func registerListner() -> Void {
_ = eventListner?.addCreateListener(responseHandler: { (create) in
if let model = create as? ConciergeServices{
self.allConciergeService.append(model)
}
}, errorHandler: { (error) in
})
_ = eventListner?.addUpdateListener(responseHandler: { (update) in
if let model = update as? ConciergeServices{
self.allConciergeService = self.allConciergeService.map { (service) -> ConciergeServices in
if service.objectId == model.objectId{
return model
}
return service
}
}
}, errorHandler: { (error) in
})
_ = eventListner?.addDeleteListener(responseHandler: { (delete) in
if let model = delete as? ConciergeServices{
self.allConciergeService.removeAll { (service) -> Bool in
return service.objectId == model.objectId
}
}
}, errorHandler: { (error) in
})
}Hello @Vinod_Sahu,
I’ve simplified your code a little, just to print the logs when listeners are triggered and everything works fine for me in your app:
func registerListner() -> Void {
_ = eventListner?.addCreateListener(responseHandler: { (create) in
if let model = create as? ConciergeServices {
print("CREATE Result: \(model)")
}
}, errorHandler: { (error) in
print("CREATE Error: \(error.message ?? "")")
})
_ = eventListner?.addUpdateListener(responseHandler: { (update) in
if let model = update as? ConciergeServices {
print("UPDATE Result: \(model)")
}
}, errorHandler: { (error) in
print("UPDATE Error: \(error.message ?? "")")
})
_ = eventListner?.addDeleteListener(responseHandler: { (delete) in
if let model = delete as? ConciergeServices {
print("DELETE Result: \(model)")
}
}, errorHandler: { (error) in
print("DELETE Error: \(error.message ?? "")")
})
}
- I’ve added a new record to the ConciergeServices table.
- I’ve updated one of the ConciergeServices table’s value.
- I’ve deleted that record.
All listeners triggered as expected:
Please make sure you handle the server response correctly in case this issue still appears.

Hello @Vinod_Sahu
Could you tell us if you disconnect listeners when exiting the foreground? Or do you just minimize the app and then open and subscribe again?

Inna
Yes When moving in Background removed listener.
Could you please attach an archive with Xcode project which reproduces this issue and the steps we can follow to reproduce it.
Regards,
Olha
Can I share code here ? because its public platform
Also this is Apple TV Project
Sure

I received your email and created the internal ticket BKNDLSS-23323 to investigate this issue as soon as possible.

Hello @Vinod_Sahu ,
As far as I couldn’t build the project you’ve sent because of “No such module” errors, I’ve checked your AppDelegate class and recreated the listeners methods in my test project.
I’ve created 7 tables with the name fields and added the create/update/delete listeners for every class (21 listeners in total).
I have no issues with RT. I’ve added some logs to check if subscriptions a created and deleted correctly and as you see on the videos attached below - 21 listeners are created on applicationWillResignActive() and all of them are removed on applicationWillEnterForeground(). After the applicationWillResignActive() is called the 21 subscriptions are created (no more no less):
Video 1. Remove listeners with the removeAllListeners() method
Video 2. Remove listeners with the removeCreate/Update/DeleteListeners() methods
As you can see on the video everything works fine, all listeners are triggered after the applicationWillResignActive() is called.
Since there were no RT changes in Swift-SDK for a long time I only can advice you to update to the lates version of Swift-SDK (6.1.2) and check your project carefully, maybe some delays in the DispatchQueue may cause the problems with resubscriptions.
I’ll attach my working test project, maybe it could be helpful, but unfortunately I can’t help here more than this:

Hello Olha,
Thank you so much for your support. I run your code on my Apple TV and still facing the issue. I have replied on personal email. Could you please run that code and let me know that is compatible with Apple TV or not.
