setException deprecated

[wolfAle]

Hi guys,

I'm working on an old codebase and we have many warnings about:
'exception' is deprecated: 'BFTask' exception handling is deprecated and will be removed in a future
It happens in cases like this:

@try {
        [[ILRLogin sharedManager] activeWithServer:server];
        LRSession *session = [[ILRLogin sharedManager] getAuthSession];
        [session onSuccess:^(id result) {
           ............
        } onFailure:^(NSError *err) {
           ............
        }];        
    } @catch (NSException *exception) {
        [task setException:exception]; --> HERE
    }

or even in the caller, where I check if(task.exception).
I googled a lot but I couldn't find advices about what to do instead.
Is there a replacement method? Should I just ignore the exception in the catch block?
Can you please point me in the right direction here?

Thanks,
Alessandro
