Add tvOS target

[nickygerritsen]

I'm not sure whether you already want to add this before the watchOS SDK gets a GM or stable release, but nevertheless you can then probably use it later without changing much. I needed it anyway to test an SDK I am creating on tvOS so I might as well create a PR for it :).

This is fantastic, thanks for putting this together.

In order to keep Carthage installs from breaking, we can't ship a shared scheme. Do you mind _un_sharing the scheme for now, and I will make a branch that you can point at that will have a shared scheme?

[nickygerritsen]

No problem, will do this tomorrow :)

[nickygerritsen]

OK it is unshared now. The scheme is now not committed, because it is in my xcuserdata directory. Is that correct or should I commit the file anyway?

[gfontenot]

Nope, that's exactly right. I'll check that box in a tvos branch and that'll commit it into the repo.

[nickygerritsen]

But you can't access that box now right? Because the scheme is not there... Or do I miss something here

[gfontenot]

It is. Xcode auto-creates the scheme for the current user when you open the project.

[nickygerritsen]

Ahhhh ok. Magic!

[nickygerritsen]

@gfontenot Are you waiting on me for something to merge this one or am I missing something?

[gfontenot]

Nope, sorry, just haven't had time. Will get to this ASAP.

[gfontenot]

bam

asap'd

Thanks!

[gfontenot]

And I've created a tvos branch if anyone wants to point at that directly.
