A Combine location publisher for CLLocationManager.
// Requirements: a NSLocationWhenInUseUsageDescription entry in Info.plist
// Usage: @State var locator = CLLocationManager.publishLocation()
// and
// .onReceive(locator) { location in
// Improvements needed: Move requestWhenInUseAuthorization into its own publisher and perhaps have a combineLatest pipeline for both authorized and valid location.
// A configuration param to init(), e.g. so each manager can have the same distanceFilter.

Concrete proposal for async semantics in Swift

Async/Await for Swift

Introduction

Modern Cocoa development involves a lot of asynchronous programming using closures and completion handlers, but these APIs are hard to use. This gets particularly problematic when many asynchronous operations are used, error handling is required, or control flow between asynchronous calls gets complicated. This proposal describes a language extension to make this a lot more natural and less error prone.

This paper introduces a first class Coroutine model to Swift. Functions can opt into to being async, allowing the programmer to compose complex logic involving asynchronous operations, leaving the compiler in charge of producing the necessary closures and state machines to implement that logic.
