##GoSwift - Go Goodies for Swift.

Bring some of the more powerful features of Go to your iOS / Swift project such as channels, goroutines, and defers.

###Install (iOS and OS X)

####CocoaPods

You can use CocoaPods to install the GoSwift framework.

Add the following lines to your Podfile.

use_frameworks!
pod 'GoSwift'

The import GoSwift directive is required in order to access GoSwift features.

####Manual

Just drop the go.swift file into your project.

There is no need for import GoSwift when manually installing.

###Features

• Goroutines
• Defer
• Panic, Recover
• Channels
  • Buffered Channels
  • Select, Case, Default
  • Closing
• Sync Package
  • Mutex, Cond, Once, WaitGroup
• Error type

###Run an Example

Using terminal clone this repository and enter the goswift directory. Each example has a swift and go file that contain the same logic.

./run.sh examples/goroutines.swift
./run.sh examples/goroutines.go

###Example

Note that the following example and all of the examples in the example directory originated from http://gobyexample.com and Mark McGranaghan

Go

package main

import "fmt"

func main() {
	jobs := make(chan int, 5)
	done := make(chan bool)

	go func() {
		for {
			j, more := <-jobs
			if more {
				fmt.Println("received job", j)
			} else {
				fmt.Println("received all jobs")
				done <- true
				return
			}
		}
	}()

	for j := 1; j <= 3; j++ {
		jobs <- j
		fmt.Println("sent job", j)
	}
	close(jobs)
	fmt.Println("sent all jobs")

	<-done
}

Swift

func main() {
	var jobs = Chan<Int>(buffer: 5)
	var done = Chan<Bool>()

	go {
		for ;; {
			var (j, more) = <?jobs
			if more {
				println("received job \(j!)")
			} else {
				println("received all jobs")
				done <- true
				return
			}
		}
	}

	for var j = 1; j <= 3; j++ {
		jobs <- j
		println("sent job \(j)")
	}
	close(jobs)
	println("sent all jobs")

	<-done
}
