APAsyncDictionary is a wrapper on NSMutableDictionary that performs actions in own serial queue and return results to caller's thread. And it could be very useful when application uses dictionary concurrently from different threads.


  • Thread safety
  • Get object for key asynchronously
  • Set object for key
  • Set objects and keys from any NSDictionary
  • Remove object for key
  • Remove objects for NSArray of keys
  • Remove all objects for all keys
  • Get objects count asynchronously
  • Get all keys asynchronously
  • Get all objects asynchronously


Add APAsyncDictionary pod to Podfile


// instantiation
APAsyncDictionary *dictionary = [[APAsyncDictionary alloc] init];
// get object for key
__block id someObject;
[dictionary objectForKey:@"key" callback:^(id <NSCopying> key, id object)
    someObject = object;
    // do something with object
// get object for key synchronously
someObject = [dictionary objectForKeySynchronously:@"key"];
// set object
[dictionary setObject:object forKey:@"key"];
// set objects and keys from dictionary
[dictionary setObjectsAndKeysFromDictionary:@{@"key1" : object1, @"key2" : object2}];
// remove object for key
[dictionary removeObjectForKey:@"key"];
// remove objects for keys from array
[dictionary removeObjectsForKeys:@[@"key1", @"key2"]];
// remove all objects
[dictionary removeAllObjects];
// get objects count
[dictionary objectsCountCallback:^(NSUInteger count)
    // do something with count    
// get objects count synchronously
NSUInteger count = [dictionary objectsCountSynchronously];
// all keys
[dictionary allKeysCallback:^(NSArray *keys)
    // do something with keys
// all objects
[dictionary allObjectsCallback:^(NSArray *objects)
    // do something with objects
