Concurrency in Swift: One possible approach

• Author: Chris Lattner

Introduction

This document is published in the style of a "Swift evolution manifesto", outlining a long-term view of how to tackle a very large problem. It explores one possible approach to adding a first-class concurrency model to Swift, in an effort to catalyze positive discussion that leads us to a best-possible design. As such, it isn't an approved or finalized design

// Swift's untyped errors are a goddam PiTA. Here's the pattern I use to try to work around this.
// The goal is basically to try to guarantee that every throwing function in the app throws an
// ApplicationError instead of some unknown error type. We can't actually enforce this statically
// But by following this convention we can simplify error handling

enum ApplicationError: Error, CustomStringConvertible {
    
  // These are application-specific errors that may need special treatment
  case specificError1
  case specificError2(SomeType)
