I'm about to publish a radio app that uses the stream with HTTP with 192kbps.
The fact that it is with HTTP, will it be a problem to be published in the Apple Store?
It's not unusual for apps in the store to include HTTP. See the examples here: https://developer.apple.com/streaming/examples/
And QA1767 for details: https://developer.apple.com/library/content/qa/qa1767/_index.html
Is there some specific reason you ask?
