TIL that self-updating mobile apps are a thing. It is quite surprising to me that the app store gatekeepers don't force all app changes through their vetting process! Has this always been the case, or is this a new development?

Every time you launch YouTube, or TikTok or Facebook, or any large game, (or any App with a WebView), yeah. https://docs.shorebird.dev/faq#does-shorebird-comply-with-pl... https://docs.shorebird.dev/faq#does-shorebird-comply-with-ap...

There are also various other commercial services offering code push. Even Microsoft has one: https://learn.microsoft.com/en-us/appcenter/distribution/ina...

The stores obviously can punish apps who break their terms (not just around updates), but code push is ubiquitous because so many apps need the ability to fix bugs w/o waiting for every single user to click "update" in a store.

I am very curious about this too. Wouldn't this allow you to remotely inject malware into an app? For my own, non-malicious, project, I'd love for this to work, but I don't want the app store gods to wreak vengeance on me.

UPDATE: I found this.

Examples of SDK-caused violations

Your app includes an SDK that downloads executable code, such as dex files or native code, from a source other than Google Play.

There are some limitations on what code push is allowed to do. Shorebird's docs[0] go over some of the details for the Play and App stores.

It's be because they can't anyways, what about web pages, feature flags & server side rendered views? The review process is mostly there to not circumvent their payment process.
