Implementing Concurrency in an Advanced Architecture
summary
Concrete code shows where to start async work: put IO async at the entity gateway and CPU work inside use cases, not sprinkled in views. Compares callbacks via protocols, continuation with closures, GCD/DispatchQueue, OperationQueue, Bright Futures and Rx; explains retain cycles, when the use case must be retained, how to cancel and add dependencies, and tradeoffs (simplicity vs composability). Recommendation: pick one or two approaches and apply them consistently.
