  • Mutex, Cond, Once, WaitGroup

##Example

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

Go

package mainimport"fmt"funcmain() {jobs:=make(chanint,5)done:=make(chanbool)gofunc() {for {j,more:=<-jobsifmore {fmt.Println("received job",j)}else {fmt.Println("received all jobs")done<-truereturn}}}()forj:=1;j<=3;j++ {jobs<-jfmt.Println("sent job",j)}close(jobs)fmt.Println("sent all jobs")<-done}

Swift

func main(){varjobs=Chan<Int>(5)vardone=Chan<Bool>()go{for ;;{var(j, more)=<?jobsif more{println("received job\(j!)")}else{println("received all jobs")done<-truereturn}}}forvar j=1; j<=3; j++{jobs<- jprintln("sent job\(j)")}close(jobs)println("sent all jobs")<-done}

###Run an Example

Each example has a.swift and.go file that contain the same logic.

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

##Installation (iOS and OS X)

Add the following to your Cartfile:

github "tidwall/GoSwift"

Then runcarthage update.

Follow the current instructions inCarthage's READMEfor up to date installation instructions.

Theimport GoSwift directive is required in order to access GoSwift features.

Add the following to yourPodfile:

use_frameworks!pod'GoSwift'

Then runpod install with CocoaPods 0.36 or newer.

Theimport GoSwift directive is required in order to access GoSwift features.
