Hello @Vinod_Sahu

Unfortunately, according to the log, we cannot determine what exactly leads to the crash.
Could you please specify what version of the iOS SDK you use and would be great if you provide us with a code snippet that causes the problem.

Regards, Vlad

Vinod_Sahu · March 2, 2021, 8:49am

Hi,

Using 6.2.10 Backendless Version. I also getting exactly why app crashing. My crash report only providing that.

Hello @Vinod_Sahu ,

Unfortunately we cannot reproduce the issue without knowing the error description and steps we can follow to reproduce it.
According to the log you’ve provided, you’re using RT in your project. After the RT is connected some request brokes your app.
Unfortunately this log doesn’t contain any information about the request, that’s why @vladimir-upirov asked you to provide a code snippet and steps that can help us to reproduce this crash.

Regards,
Olha

Vinod_Sahu · March 8, 2021, 9:05am

Hi Olha,

Here is my code. Could you please check there is memory leak. Because app crashing on production only and not getting exact error

func getData() {

    let queryBuilder = DataQueryBuilder()
    queryBuilder.pageSize = 100
    
    dataStore.find(queryBuilder: queryBuilder, responseHandler: { [weak self] foundTenants in
        
        if foundTenants.capacity > 0 {
            
            if let models = foundTenants as? [Event] {
                
                self?.allEvents = models
            }
        }
    
    }, errorHandler: {  fault in
        
        print("Error : \(#function)-\(#line)",fault.description)
    })
}

func getEvent(objectId:String,response:@escaping (Event?)->Void) {
    
    let queryBuilder = DataQueryBuilder()
    queryBuilder.whereClause = "objectId = '\(objectId)' OR eventid = '\(objectId)'"
    //queryBuilder.setWhereClause(whereClause: "objectId = '\(objectId)' OR eventid = '\(objectId)'")
    
    dataStore.find(queryBuilder: queryBuilder, responseHandler: { foundTenants in
        
        //print("Total Event in ----------------------",foundTenants.count,"objectId = '\(objectId)'")
        response((foundTenants as? [Event])?.first)
    
    }, errorHandler: {  fault in
        
        response(nil)
        print("Error : \(#function)-\(#line)",fault.description)
    })
}

Hello @Vinod_Sahu,

I’ve created an internal ticket BKNDLSS-24320 to investigate this issue.

Regards,
Olha

olhadanylova · March 9, 2021, 11:28am

Also please provide your application id.

Regards,
Olha

Vinod_Sahu · March 9, 2021, 11:42am

App ID : CEE6C01E-DD2D-47F5-BE7A-2EF06B5AA69D

olhadanylova · March 9, 2021, 2:32pm

Unfortunately I cannot reproduce this issue.
The getData() and getEvent() methods work properly and return data as expected. It’s impossible to figure out the problem without knowing details of your application.
Also it’s weird that it’s crashing only in the production mode but works fine in the development one (as I understood)

Regards,
Olha
