Can't access cache by sync methods

[aelam]

I expect to get the cache from the return value rather than in a block
Is there an alternative way to implement that makes it can return cache value directly?

- (BOOL)loadDataForKey:(NSString *)key
          withCallback:(SPTPersistentCacheResponseCallback _Nullable)callback
               onQueue:(dispatch_queue_t _Nullable)queue;

+1 for this. In our case, we orchestrate background jobs using Rx observables so it would be useful to also have sync methods to access the cache. Having to deal explicitly with GCD queues forced us to do some little hacks that we'd like to avoid
