Concurrency means executing more than one task at a time. In iOS, we can achieve concurrency using Operation Queues, Dispatch Queues (GCD), or Threads.

The statements in the closure of the lazy property execute only if you read the property.
If you never read a lazy property, you can avoid unnecessary allocations and computations.
You can access stored property inside the lazy property.
