Shader compiling error with Xcode 6

[speaktoalvin]

I almost solved all the bugs which i got in the Xcode. When i run this code now its showing that "Failed to compile shader!" which comes in this method.

 func compileShader(shaderName : NSString , shaderType : GLenum) -> GLuint.

This repository stopped working properly after changes were made early on to the Swift language. After efforts on my part to repair the breakages, I have decided to use Metal instead for my purposes. You can see example code here.
