Support installation with Homebrew

[pepicrft]

Installation can be simplified by using Homebrew. The purpose of this issue is to provide a Homebrew formula that tells Homebrew how to install XcodeGen

[yonaskolb]

I would love that! I remember hearing you're not allowed to submit formula's for your own project, so if you could to it, that would be great!

You can add your own repository, called Tap where the definition is. I'm working on the formula but I'm facing some issues with the generated binaries, since it depends on other frameworks that have to be linked once moved to the system directory.

Forget about that, it's exactly what you do here https://github.com/yonaskolb/XcodeGen/blob/master/Makefile

Where did you find documentation about that? I always wondered how that can be done.

[yonaskolb]

Yeah one of the guys from YAMS pointed me in the right direction
jpsim/Yams#39
I've been meaning to write a blog post about it, but I think it's supposed to be a solved problem when Swift 4 comes out

[pepicrft]

I see. I wonder why it only happens with that dependency and not with the other. I feel I'm missing something :/

[yonaskolb]

It's because Yams relies on a C module - libCYaml.dylib

This has already been done:

brew tap yonaskolb/XcodeGen git@github.com:yonaskolb/XcodeGen.git
brew install xcodegen
