Async Functions - Swift Programming

An async function can suspend before returning a value to the caller.

Await a result

async_functions.swift

func doubled(_ value: Int) async -> Int {
    return value * 2
}

let input = 
let result = await doubled(input)
let message = "result=\(result)"

print(message)

func doubled(_ value: Int) async -> Int {
    return value * 2
}

let input = 
let result = await doubled(input)
let message = "result=\(result)"

print(message)

func doubled(_ value: Int) async -> Int {
    return value * 2
}

let input = 
let result = await doubled(input)
let message = "result=\(result)"

print(message)

async function `await` marks the point where the caller waits for an async function result.
