iOS Developer: From Noob to Ninja in 30 days — Day 5, Three REAL use cases for Closures (Asynchronous, Synchronous, Property)

In this post I will be applying three REAL use cases for Closures, these closures are used everywhere in any application.

  • Asynchronous Callback (URLSession, DispatchQueue, DispatchGroup)
  • Synchronous Callback (Append String, Sort)
  • Property Callback (Network, Append String, Sort)
