ITV has worked with Candyspace over the last 7 years to produce an iPhone, iPad, Android and Web app for their ITV Hub application that lets their users watch live and on demand content on the go. ITV wanted a similar app for Apple TV as their customers were constantly asking for it in the iPhone/iPad reviews.
Another contractor and I were hired for a 3 month contract to create the tvOS app for ITV Hub. It was a lot of work in a short amount of time so we really had to hit the ground running.
It was a completely agile process with ITV coming in house for demos and sprint planning weekly. We also worked closely with Apple to make sure that our app was compatible with Apple's new UK TV service.
The app has an in-app purchase for premium, the ability to sign-in and register, search functionality, parental controls and the ability to watch live channels, and stream on-demand content by category or channel. It was launched successfully in December 2017.
