iOS Restrictions

Apple usually restricts sideloading, though that can be worked around by using stuff like AltStore, SideStore, etc. In the EU, Apple was forced to allow sideloading to users of Apple devices for all EU citizens with an Apple Account set to any EU member country. for many other users globally, they have to use workarounds. iOS also restricts JIT (Just-In-Time Compilation) for every single iOS app, the Safari browser and any other browser are allowed to use JIT. There are iOS apps that can utilize JIT, but you need workarounds, like StikDebug, LocalDevVPN, etc. They restrict it for "security" purposes.
