Xcode 6 compatibility

These changes fix hyperloop-ios to work with Xcode 6. One point to note:
If you try to include any frameworks, it doesn't seem to pull them in.
However, for a project i.e basic, physics, etc it works.

I now am suspicious that there are issues with hyperloop-common that prevent frameworks from being included correctly.

When you try to run spritekit or the opengl or the life examples you get the following error message:


```
