iOS 9 SSL issue on device

I am using v3 of Backendless on iOS. On the simulator everything is OK, but on the device even a simple data retrieval comes back with an error.
I’ve added the following to my Info.plist file:
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
I have the following code in my .m file:
QueryOptions *queryOptions = [QueryOptions query];

queryOptions.relationsDepth = @1;

BackendlessDataQuery *dataQuery = [BackendlessDataQuery query];

dataQuery.queryOptions = queryOptions;

[backendless.persistenceService find:[Variables class] dataQuery:[BackendlessDataQuery query] response:^(BackendlessCollection *collection){

NSArray *currentPage =[collection getCurrentPage];

NSMutableDictionary *ret = [[NSMutableDictionary alloc] initWithCapacity:[currentPage count]];

for (Variables *variable in currentPage)
{
ret[variable.key] = variable.value;
}

NSLog(@"%@", ret);

}
error:^(Fault *fault) {

NSLog(@“Backendless error: %@”, fault.description);

completion(nil);

}
];
and it comes back on the device with the following error:
CFNetwork SSLHandshake failed (-9806)

Solved: I removed the application from the device, cleared the project and reinstalled it.
