Overview
========

This sample Xcode project demonstrates how to build Go code for OS X / iPhone / iOS Simulator executables, as well as calling to and from Go.

*This project installs its own local version of Go 1.5 and does not use or modify in any way any prior Go installation.*

Getting Started
===============

1. Clone repo and `cd` into the directory
2. Run `./bootstrap.sh`
3. Open the Xcode project

If you need to access the local Go environment from Terminal, `cd` into the directory then run `source env.sh`. This will define `GOROOT`, `GOPATH`, etc...

Limitations
===========

1) Go code is built with absolute addressing which triggers a warning when linking the executable

https://github.com/golang/go/issues/12681

```
(null): PIE disabled. Absolute addressing (perhaps -mdynamic-no-pic) not allowed in code signed PIE, but used in __cgoexp_45a75e65c81e_Test from build/iphoneos/main.a(go.o). To fix this warning, don't compile with -mdynamic-no-pic or link with -Wl,-no_pie
```

2) Go code is not built with bitcode when building for iPhone

https://github.com/golang/go/issues/12682

3) Go code fails to build for iOS Simulator on i386 (the Xcode project is therefore configured to only use it in 64 bit mode)
