What API are you using to keep running in the background? Most likely you are misusing it on some manner and have yet to get caught by App Review.

I've seen this bypassed via background audio and background location.

The app does background audio, and its use is legitimate. It is an audio app.

But the point is - there's no fundamental restriction from the OS itself.

You contradicted yourself.

Whether you want to call it a “restriction”, “a lack of permission without being X type of activity”, or “it works because the app exhibits Y behavior”, it’s all functionally a restriction.

You can run some background activities that are not audio apps, but you’re at the mercy of iOS’s decision to keep your task active or not. If you’re off the charger, all bets are off. iOS’s dev docs make this very clear.

[lostmsu]

No, basic set theory: not every restriction is a fundamental restriction.

[redserk]

Elaborate?

[lostmsu]

I said NOT(rule in "fundamental restrictions") AND (rule is XXX). You showed (XXX in "restrictions"). It would have been sufficient to prove my statement false if "fundamental restrictions" === "restrictions", but it is not.

Another way of phrasing this: There is a fundamental restriction, with a carve out for a few specific things, including audio playback.

[lostmsu]

I don't think you understand the difference between a fundamental restriction and a restriction in general.

[lxgr]

What’s not fundamental about the OS pausing any background thread that doesn’t have an excuse to continue running from a relatively short list?

I am not here to debate meaning of words. If LLaMA 3.1 8B can understand the difference between a fundamental restriction and a restriction in general on its own, so can you. If you feel like this topic is worth your time for intellectual pursuit, feel free to debate with it: https://huggingface.co/meta-llama/Llama-3.1-8B-Instruct I don't feel that it is worth mine. See if you can convince it the definition your are implying is more accepted than the one I am.
