Available methods in LPConcurrency

+ (void)performBlockOnMainQueue:(void(^)(void))block; // async
+ (void)performBlockOnMainQueueSynchronously:(void(^)(void))block; // sync
+ (void)performBlockOnMainQueue:(void(^)(void))block afterDelay:(NSTimeInterval)delay;

+ (void)performBlockInBackground:(void(^)(void))block;

+ (void)performBlockSynchronously:(void(^)(void))block;
+ (void)performBlockSynchronouslyOnMainQueue:(void(^)(void))block;

Example internal implementation

+ (void)performBlockOnMainQueue:(void(^)(void))block afterDelay:(NSTimeInterval)delay
{
    dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, delay * NSEC_PER_SEC);
    dispatch_after(popTime, dispatch_get_main_queue(), block);
}
