I don’t think anyone will stop you from doing it, as long as you’re not copying and pasting our materials 🙂

I’m glad this tutorial helped. Always happy to hear what readers think!

Cheers,

AppleTV has a strict spec for HLS, see [Apple Developer Documentation](https://developer.apple.com/library/tvos/documentation/General/Reference/HLSAuthoringSpec/Requirements.html#//apple_ref/doc/uid/TP40016596-CH2-SW1).

Thanks Kelvin. Your tutorial was a good starting point in our project. May we know how can we get the AppleTV setting on “Subtitle Language” under the “Audio and Video” setting page, Swift/Object-C code is fine?

Can we use either swift or Objective C while using TVML/TVJS?

Hi,

I am looking for some **tvOS** SDKs or API’s used for payments like **Braintree** and **Stripe** which are being used on **iOS**. As there is no Apple pay feature on Apple TV/ tvOS, how can payments be processed?

Thanks,

What would be the best approach if I need to make REST API calls to retrieve the content to display? Can I still use TVML type of apps to make REST API calls to retrieve data?

Hi kelvin,

I am beginner to tvOS and following your tutorials on TVOS, all are very helpful.  
I am getting following error while running the hello world program which you explained in above article:  
ITML : SyntaxError: Unexpected token ‘\<’…{  
line = 1;  
sourceURL = “[http://localhost:9001/js/application.js](http://localhost:9001/js/application.js)”;  
}

I found following link over the web but this article did not help:  
.[tvos - tvml syntax error : Unexpected token '\<' - Stack Overflow](http://stackoverflow.com/questions/39188648/tvml-syntax-error-unexpected-token)  
Please provide me any solution for this issue

Thanks,

Hi Kelvin, thanks for creating this tutorial. I’m a complete beginner to Xcode, Swift and tvOS development and your tutorial was helpful to get off the ground. I’m using XCode 8 and the latest Swift version and noticed that the API has changed a bit since the tutorial was published. Specifically the line where you grab the bounds of the main screen in the didFinishLaunchingWithOptions function have changed:

What was:

window = UIWindow(frame: UIScreen.mainScreen().bounds)

Is now:

window = UIWindow(frame: UIScreen.main.bounds)

Small thing I know and code-complete (or whatever it’s called in Xcode) helped a lot but took a novice like me some time to confirm my change was correct.

Hey Steve!

Thanks for pointing that out. I’ve made the following changes:

- Updated the final `RWDevCon` project to Swift 3
- Updated the `application(didFinishLaunchingWithOptions:)` text to match the changes

Sorry for the trouble, I totally understand the frustration of finding out how to migrate old code to new code.

Hey nmatiyali1!

JavaScript is not our friend ☹

My advice is to make sure you’ve got the " ` " character at the right place. When I was writing this, missing that was a frequent cause of errors. Otherwise, it’s likely you’ve just missed an angle bracket when declaring your elements in `createAlert` of `application.js`.

Hi Kelvin,

Thanks for sharing tutorial. Its explained in full detail ,was able to understand all itsy-bitsy of apple Tv development. However as I am referring other tutorials too, they are suggesting tvml and tvjs for development. And I am an ios developer ,will be developing apple TV app for first time, so can you please guide me about choice of language for TV development? Can I use swift,Obj-C and TVJS all together? or what would you recommend if my app uses servers and custom databases , should I be opting for TVML and TVJS or develping with swift is fine? As my app has third party library references too which are written in swift and payment gateway integration. Please do guide me with your expertise.

Does TVML support Fairplay DRM properly? We are unable to play DRM protected files due issues in loadAssetID? Has any one tested TVML Fairplay?
