go2xcode

go2xcode converts a Go package into a Xcode project that targets iOS 8.3.

Note: Not maintained, use gomobile

$ go get github.com/rakyll/go2xcode

Usage

$ go get -d golang.org/x/mobile/example/basic/...
$ go2xcode golang.org/x/mobile/example/basic
$ cd xcode
$ xcodebuild # or open the Xcode project.

Note: go2xcode requires Go 1.5 darwin/arm and darwin/arm64 cross compilers.

In order to build these cross compilers, you need to Go 1.5 source.

Go 1.5 requires Go 1.4. Read more about this requirement at http://golang.org/s/go15bootstrap. Set GOROOT_BOOTSTRAP to the GOROOT of your existing 1.4 installation or follow the steps below to checkout go1.4 from the source and build.

$ git clone https://go.googlesource.com/go $HOME/go1.4
$ cd $HOME/go1.4
$ git checkout go1.4.1
$ cd src && ./make.bash

Clone and build Go 1.5 and add Go 1.5 bin to your path.

$ git clone https://go.googlesource.com/go $HOME/go
$ cd $HOME/go/src && ./make.bash
$ export PATH=$PATH:$HOME/go/bin

And build the cross compilers.
