Add support for tvOS

[CarlEkman]

What?

I've been attempting to extend the single-target framework for tvOS-support, but there is something still not working (something missing in the Build Settings I assume). I'm looking for input, and to see if this build working frameworks on other machines.

Why?

We currently show in the README that we support tvOS, but that's not true. It should also be a quite straightforward extension, if this would work.

Discussion

Does anyone know what's preventing this from building correctly? The .framework file I get is empty when I import it into another project (i.e. no classes or APIs are exposed).

I just moved this code around to make the preprocessor checks cleaner.

Awesome!

@fennecOS @mansbernhardt Any chance one of you could try to build the framework for tvOS on your machines? The tests pass, but the product itself seems empty when I try it out...

[CarlEkman]

According to this reference, I should add arm64 to Valid Architectures, but that didn't change anything for me.

Selecting the Apple tvOS simulator and running the test on that builds and runs the test. Looking into the FW bundle says "Flow" binary is 1.9MB.

Building for generic Apple tvOS device gives a binary of 1.8MB.

So it seems to work, no?

[CarlEkman]

@mansbernhardt yes, it looks good :) But for some reason when I include that framework in a template tvOS project, I can't seem to use anything in the framework. I've tried including it the same way in both MacOS and iOS projects (which both work), but not on tvOS. Does anyone else experience the same thing?

[mansbernhardt]

Do you have a sample project I can try out on the simulator?

[CarlEkman]

@mansbernhardt I was about to link you a new repo with just a single-view template tvOS app inside, but I think I found what's wrong. The contents of the framework is being built for arm64, which is correct for physical AppleTVs, but the simulator runs on x86_64, so it ignores all those sources when running the simulator.

I'm now trying different configurations of Build Active Architectures Only together with Architectures and Valid Architectures in Flow...

Hey, what do you know! Turns out everything works fine when using Carthage 😄 It was just me being curious as to why the .framework didn't work when I built it locally. Guess it isn't that simple. Never mind my talk about architectures, it looks like this works fine now.
