Apple is reportedly pushing back on 'vibe coding' iPhone apps, a category that allows developers to create tools without needing to be officially distributed by the App Store. The apps, which allow users to create apps without being officially distributed, violate longstanding App Store rules that prohibit running code that changes the way the app or other apps function. Apple has stated that these apps should be self-contained in their bundles and must make the source code completely viewable and editable by the user. The fix for at least one of these apps may be simple, generating app previews in a browser not inside the vibe coding app itself.
