concurrency is a collection of concurrency primitives which helps increase testability
import Concurrency
// Create `DispatchQueueFactory` instance
let factory = DispatchQueueFactory()
// Build `main` queue from factory
let mainQueue = factory.main()
// Build `global` queue with QOS
let globalQueue = factory.global(qos: .background)
// Build `private` queue
let privateQueue = factory.privateQueue(label: String(describing: self),
qos: .background,
attributes: .concurrent,
autoreleaseFrequency: .inherit,
target: nil)For testing purposes, you can use TestConrurrency target.
import TestConcurrency
let testQueue = TestDispatchQueue()
// Run block immediately
testQueue.async {}- iOS 13.0+ / macOS 10.15+ / tvOS 11.0+ / watchOS 6.0+

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler. It is in early development, but concurrency does support its use on supported platforms.
Once you have your Swift package set up, adding concurrency as a dependency is as easy as adding it to the dependencies value of your Package.swift.
dependencies: [
.package(url: "https://github.com/space-code/concurrency.git", .upToNextMajor(from: "0.0.1"))
