Apple thread discussing the same issue.

+ (NSData *)sendSynchronousRequest:(NSURLRequest *)request  
    returningResponse:(__autoreleasing NSURLResponse **)responsePtr  
    error:(__autoreleasing NSError **)errorPtr {  
    dispatch_semaphore_t    sem;  
    __block NSData *        result;  

    result = nil;  

    sem = dispatch_semaphore_create(0);  

    [[[NSURLSession sharedSession] dataTaskWithRequest:request  
        completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {  
        if (errorPtr != NULL) {  
            *errorPtr = error;  
        }  
        if (responsePtr != NULL) {  
            *responsePtr = response;  
        }  
        if (error == nil) {  
            result = data;  
        }  
        dispatch_semaphore_signal(sem);  
    }] resume];  

    dispatch_semaphore_wait(sem, DISPATCH_TIME_FOREVER);  

   return result;  
}
