Who can suggest a reliable app developer for apple tv?

Hello, users of this form. Who can suggest a reliable app developer for apple tv?

To be honest, I have not yet met the developers for apple tv. Perhaps it is difficult or expensive.

It seems to me that Apple is already a leader in streaming, or rather, they act as a serious competitor in the field of YouTube streaming. After all, now the service, which includes original programs as well as third-party channels, is one of the largest OTT platforms available. I decided to keep up with the trends, and began to search for information about the creation of the Apple tv app. A friend recommended an article to me, read here, it is very informative, I advise you to read it.
